- "If I had accepted things, I would be a cocktail waitress in Vegas like my mother and I never would have gone to college and I never would have moved a thousand miles away to work at Queen Consolidated and I never would have believed some crazy guy in a hood when he told me I could be more than just some I.T. girl."
- —Felicity to Oliver[src]
Felicity is the daughter of an unnamed man, and Donna Smoak, the partner-in-vigilantism and a good friend of Oliver Queen, John Diggle, and Sara Lance. She is the primary contact between The Arrow and SCPD Officer Quentin Lance. She is also a friend and former employee of Walter Steele. Felicity is very intelligent and extremely proficient with electronics, which is why both Walter and Oliver initially approached her for help in their separate problems.
Felicity was drawn into Oliver's vigilante team due to her desire to find her abducted boss and friend, Walter Steele, who, prior to his kidnapping, had secretly asked her to look into some suspicious things happening with his money and business. When she finds evidence confirming his suspicions, Walter asks her to stop looking further because he didn't want to put her in more danger. However, she stubbornly continues to look into it, and after Walter is kidnapped, she realizes that he might have been taken due to the things she found.
Meanwhile, Oliver Queen has approached Felicity for help with a few odd tasks (that he couldn't complete himself), using ridiculous cover stories in a vain attempt to hide the true purpose of his request. Putting two and two together, Felicity begins to suspect that Oliver was involved with Starling City's new vigilante archer, which helps her eventually decide to approach Oliver with Walter's copy of The List (which Walter found in his and Moira's bedroom), trusting him with the information.
After Oliver is shot by his mother, he retreats to Felicity's car, revealing his identity to her and asking her to drive him to his warehouse instead of a hospital. After she and Diggle save his life, she agrees to join his team, but only until they find Walter. After Walter is found and rescued in "The Undertaking," Felicity decided to remain with the team.
In the beginning, Felicity doesn't agree with Oliver's methods in catching criminals, but later starts to loosen up after she helps capture The Dodger and realizes that what he does isn't all bad. Unfortunately, she would later be unable to get a lock on the location of a criminal, and is subsequently forced to watch a man die due to her failure. She begins to lose faith in herself until John Diggle realizes that their target was on a moving train underground, which allows her to anticipate where the train would be next and help save Roy Harper.
Felicity has gone on three undercover missions: first as a card-counter in a mob-run casino, second as a Big Belly Burger delivery girl at Merlyn Global Group, and third as bait for The Dollmaker. In the episode Time of Death, she had her first solo-mission, taking down William Tockman.
In Heir to the Demon, Felicity reveals to Oliver that the reason she rarely talks about her family is because her father abandoned her and her mother when she was young. She reputedly lived in Las Vegas with her mother until she went to college. Felicity has mentioned that she is Jewish twice so far, once to Oliver Queen in Year's End when he wishes her a Merry Christmas and she replies, "I'm Jewish," and a second time to Barry Allen in Three Ghosts, when he asks what her holiday plans are and she responds "Lighting my menorah". At a young age, Felicity became interested in computers, claiming to have built them since age 7. However, she was always fearful that she would wind up as a cocktail waitress like her mother and worked hard to escape from her circumstances. She went to M.I.T. (class of 2009), apparently having an incident with a stalker in her freshmen year, and moved a thousand miles away to work at Queen Consolidated in Starling City.
In "Lone Gunmen", Felicity is busy working in the I.T. Department when Oliver Queen walks in. Upon introducing himself and insisting that Mr. Queen was his father, Felicity accidentally mentions his father's death, backtracking apologetically and ending up babbling at him, which visibly amused Oliver. To her relief, he ignores her ramblings and gives her a bullet-ridden laptop, claiming that he'd spilled a latte on it, though she clearly dis-believes Oliver's cover-story. Felicity retrieves blueprints to the Exchange building, where Walter Steele would be bidding on the Unidac Industries auction. She also learns that the laptop belongs to Walter's competitor Warren Patel, Deadshot's employer.
In "An Innocent Man", Walter summons Felicity up to his office, but mistakenly believes she is going to be fired. However Walter instead gives her a secret task off-books. Walter explains to her that a value of 2.6 million dollars has gone missing after one of Moira Queen's transactions. He asks her to find out some of the details of the transaction discreetly. From this, Felicity unearths that there was no investment, the money in question was used to set up an offshore limited liability company called Tempest. The organization, with no ties to the government or any other company, including Queen Consolidated, seemingly only existed to facilitate the purchase of a warehouse in 2009 that was located somewhere in Starling City.
In "Legacies", Felicity researches Derek Reston for Oliver and John Diggle. Although she clearly disbelieves his excuse for doing so, her research unearths the fact that Reston had been an employee of his father, which propelled Oliver to reach out and offer Derek a second chance.
In "Vendetta", Felicity enters Walter's office to speak with him about someone else looking at his wife's financial transactions regarding Tempest. She shows him a picture (the symbol in The List) she managed to find that Walter denies having seen before, and he coldly warns her to stop looking into his wife's affairs, promising to suspend her if she continued (to keep her safe), though Walter later calls her back and gives her a seemingly blank copy of The List after he finds it in his and Moira's bedroom. After a few hours, Felicity returns to Walter's office with The List and a pair of glasses manufactured by Queen Consolidated's Applied Sciences division that allowed them to see the list of names written in invisible ink.
In "Year's End", Felicity calls Walter in the middle of dinner to tell him that Doug Miller, head of Queen Consolidated's Applied Sciences division, is on the List. She warns him that Miller may be in danger, prompting Walter to meet with him. Later, while looking at the names she'd copied onto her tablet, Oliver arrives to ask for her help again, claiming that a friend of his is a big archery fan and giving her an arrow to track down where it was delivered. Upon providing him with the information, Oliver praises her and greets her a merry Christmas before he leaves, causing Felicity to reveal to him that she is Jewish.
In "Trust but Verify", Oliver asks Felicity to decrypt the information stored on a security fob, claiming that it was part of a scavenger hunt that would award several bottles of 1982 Lafite Rothschild to the winner. Declaring her love of red wine and bring promised one of the bottles, Felicity decrypts the fob and discovers that it contained information regarding several planned heists similar to the armored-car robberies that have been occurring in the city. Oliver asks her to hold off on warning the police, saying he didn't want to get her in trouble and asking her to send him the information instead. Felicity does so, privately expressing her disappointment in the lack of wine coming her way.
In "Vertigo", Oliver and John arrive at her office and hand her a syringe and asks her to run a spectro-analysis on what he claims is an energy drink, but is in fact Vertigo. Felicity questions him on why the energy drink is in a syringe, and then walks away exasperatedly when Oliver tells her he ran out of sports bottles. However, she contacts him later that night and asks him to meet her. They go to Big Belly Burger, where Felicity admits that despite the outrageous stories he'd told her when he asked for her help, she somehow trusts him enough to share the information she has collated. She presents him with the copy of The List in her possession, telling Oliver that it may be the reason why Walter had been abducted.
In "The Odyssey", Felicity leaves her work at night and gets in her car. She turns around and sees a gunshot-wounded Green Arrow, who reveals himself as none other than Oliver Queen, much to Felicity's shock. Oliver tells her to take him to his father's old warehouse and nowhere else, which she does. When Felicity gets to the warehouse, she and thoroughly startled John Diggle operate on Oliver and manage to stop the bleeding and the effects of the gunshot wound . While Oliver was unconscious, John commented on Felicity's handling of the revelation she has discovered suspecting she kne, to which Felicity states she was already suspicious from the horrible cover stories they have told her for the favors Oliver asked her for. Felicity also learns that the "energy drink" vial given to her was Vertigo, and learned of her partial take-down of the The Count. After learning how much she has helped already, she agrees to help Oliver on a provisional basis until Walter is found.
In "Dodger", Oliver hoods up to mark a name off of the List and Felicity locks him in the Arrowcave to point out that he's about to threaten to kill a single father with a ten-year-old son. Oliver ignores her objections, prompting her to quit in the belief that it was a bad idea to get involved with them in the first place. To coax her back on the team, Oliver goes after The Dodger, a thief who forces others to steal for him with bomb collars. During their first team meeting at Big Belly Burger, Felicity notices the attraction between John and his former sister-in-law Carly, which leads to her persuading and/or daring the guys to go on dates: John with Carly and Oliver with McKenna Hall, mostly for fun, though Oliver's date also had more to do with the intention of planting a bug on McKenna's phone, which would allow them to get information about the Dodger. When Team Hood sets up a sting using one of the Queen jewels, the Dodger simply steals the bait himself. Felicity naively confronts him, which leads to him collaring her with a bomb. With Felicity guiding him through the streets via the tracking device they installed in the jewel, Oliver chases after the Dodger while Diggle attempts to disarm the collar. He manages to find and stop the Dodger, retrieving the detonator and freeing Felicity from her collar.
In "Dead to Rights", John has begun training Felicity to defend herself in case she is attacked. During their break, Oliver comes in, having just killed Guillermo Barrera, an assassin-for-hire. He gives Felicity Barrera's phone, hoping she could figure out who the target was so they could stop any another assassin who came to finish the job. Felicity manages to get the last number Barrera called, which was a front for the Chinese Triad, a restaurant called the Jade Dragon Restaurant. While Oliver goes to check it out, Felicity continues to decrypt the phone, eventually cracking through its firewalls and discovering that Barrera's target was Malcolm Merlyn. Later, after Malcolm is saved, Oliver informs them that the assassin had been Floyd Lawton, upsetting John. Felicity learns from Oliver that Lawton was the man who killed John's brother.
In "The Huntress Returns", Felicity accidentally interrupts a meeting between Oliver Queen, John, and Helena, offering to hack into the FBI database. Oliver sharply tells her to leave, trying to prevent Felicity from becoming involved with Helena's vendetta. This fails, as Helena later breaks into the I.T. Department of Queen Consolidated and threatens Felicity into hacking the FBI to find the location of her father's safehouse. Thankfully, Felicity had been in the middle of a call to Oliver's voicemail when Helena showed up, so he immediately proceeds to Queen Consolidated when he hears it. He finds Felicity tied up under her desk, quickly freeing her. Felicity explains what happened and apologizes for giving Helena the information, though the attack persuades Oliver to go after Helena with no mercy..
In "Salvation", Felicity is in the Arrowcave watching the news regarding John Nickel, one of the people on The List. With the DA's office deciding not to indict Nickel for the fire that occurred the night before, Oliver decides to go after Nickel, to which Felicity gave "100%" support. However, someone else gets to Nickel first and broadcasts his interrogation of Nickel on his website. Felicity sends the broadcast link to Oliver and Diggle, and upon seeing where the interrogation was headed, Oliver demands that Felicity track the signal it was coming from, only for Nickel to get shot on video. John contacts his friends in the NSA and discovers that the person who owns the website is a cyber-crusader called The Savior. Soon after, another video is linked onto The Savior's website, showing that Assistant District Attorney Gavin Carnahan had been kidnapped and strung up like Nickel had. Using information given away in the video, Felicity discovers that The Savior is Joseph Falk, a former employee of the Department of Transportation whose wife was killed in the Glades. Given ten minutes to find Carnahan, Felicity tries to find the location where the ADA is being held, but cannot pinpoint where the transmission is being sent from. She directs Oliver to two false locations, and as a frustrated Oliver tells her to find them faster, The Savior shoots Carnahan, shocking and upsetting Felicity. Later, when Oliver returns, she tells him she told John to leave in her loud voice and expresses guilt over her failure to find Carnahan. Oliver tries and fails to comfort her by telling them that, in their line of business, they sometimes lose a battle. Felicity then cites his policy on staying single as a good thing, saying she wouldn't know how to talk about the day she'd just had if she'd been dating someone. Her comment causes Oliver to rethink how his personal policy of isolationism is affecting him and those around him. Later, he tells Felicity that if she ever needs to tell someone about her day, she can talk to him.
In "Unfinished Business", Felicity arrives in the Arrowcave to find both Oliver and Diggle already present. Briefly teasing them about their fondness for the hideout, she shows them the news footage announcing The Count's escape from the mental institution, upsetting Oliver, who had already gone to see the Count because of the death of one of his club-goers and had discounted him as a suspect for being insane. Later, after John successfully dropped off tagged money by purchasing Vertigo, Felicity activates the tracker slipped into the bills and, at John's teasing of her throwing a pill party, admits that the only encounter she had with drugs was her accidental ingestion of a pot brownie during her freshman year, which had also triggered her nut allergy, making it an unhappy experience. John then brings them to the topic of Floyd Lawton, whom Felicity has been tracking without Oliver's knowledge at John's request. She gives him the information she had, then tries to convince John to let Oliver in on the secret, but John refuses and leaves.
Some time later, Oliver and Felicity hear a report about a Vertigo-related hostage-taking incident in Starling City Aquarium. As Oliver mixes the herbs he had to use on the junkie, Felicity wonders why he wasn't going to kill the man instead. Oliver explains to her that his sister had been in the same place, and that if she hadn't deserved to be killed for taking Vertigo, then neither did this man. When he laments that he should've killed The Count the first time around, Felicity tries to talk him out of it, only for him to point out that his choice had been wrong since the city was once again in danger due to Vertigo, and that he would kill The Count once and for all when he gets the chance. Oliver leaves after instructing Felicity to call John for backup. Later, Felicity walks into the Arrowcave to find that Oliver's things had been replaced with the club's inventory and furniture, which Oliver claims is a long story. Directed to look at the autopsy reports of the Vertigo victims, Felicity discovers that one of the junkies had died due to his allergy to chlorpromazine. Oliver promptly leaves Felicity in the Arrowcave to recheck the mental institution, realizing that the amount of anti-psychotic drugs needed to manufacture the new Vertigo could only be found in a mental institution.
In "Home Invasion", while Oliver and Diggle are working out and talking about Floyd Lawton, Felicity refutes Oliver's claim that Lawton is on another continent, explaining that she'd decrypted A.R.G.U.S.'s communication logs and ending up admitting that she dyed her hair blonde, much to Oliver's amusement and John's impatience. Felicity tells them that Lawton had returned to Starling City thanks to a sting setup by John's friend, A.R.G.U.S. agent Lyla Michaels. Felicity pulls the details of the sting for John and Oliver to study and create a counter-plan for, and later monitors the movements of Edward Rasmus, who hired an assassin to kill Laurel Lance's clients, orphaning a young boy who is also targeted for having seen the assassin's face. Just before the time for A.R.G.U.S. 's sting, Felicity gets a notification that Rasmus was on a flight manifest heading out of Starling City, forcing Oliver to choose whether to support John or help Laurel's case. He chooses Laurel, and when he returns, Felicity is tending to John's head wound. Upset that Oliver chose Laurel yet again, John tells him that his absence caused the deaths of four A.R.G.U.S. agents, and though Felicity doesn't say anything on the subject, it is clear that she agreed with John.
In "The Undertaking", Oliver brings Felicity the laptop of Harold Backman, who launders money for the white-collar criminals of Starling City, and asks her to return money to their rightful owners before they turn the laptop over to the IRS. Felicity tries to convince Oliver to apologize to Diggle for breaking his promise to him, but Oliver stubbornly refuses. After a while, Felicity walks into the club to find Oliver, only to find him conversing with Laurel Lance, whom she now meets for the first time. Excusing herself as someone who is fixing the club's router, Felicity urges Oliver to come with her so she could show him what she'd found, explaining that she hacked Cayman Fidelity and compiled a list of deposits made in the last year and had discovered a payment made on the same day of Walter Steele's disappearance. She manages to track it to Dominic Alonzo, who runs the biggest underground casino in the city. With Oliver hesitating to both storm Alonzo's place due to the unknown amount of security guarding the place and contact John for help, Felicity convinces him to let her get caught counting cards in order to place a bug on Alonzo's computer. Despite his reservations, Oliver bends to Felicity's tenacity, but insists that he plan the mission, which Felicity agrees to.
Before she goes, Felicity pays a visit to John to try and convince him to help them save Walter, but to no avail. Sometime later, she and Oliver arrive outside Alonzo's casino, where Oliver gives her another chance to back out. When Felicity refuses to do so, he assures her that he'll be right outside, and they separate. With Oliver scouting ahead and providing her the password (Snapdragon), Felicity heads in, detailing how many of Alonzo's employees were in sight and also accidentally rambling at him, much to her chagrin. Her plan to get caught counting cards goes off without a hitch, and she is brought into Alonzo's office. Introducing herself as Megan, she plants the bug and agrees to never count cards in Alonzo's casino again, only for them to find the earwig that connected her to Oliver. Having lost contact with her, Oliver storms the casino and, after getting Felicity out of Alonzo's clutches, reverts to his old method of intimidating his target into confessing the information he wanted. The fear of God placed in him, Alonzo tells them that he'd heard the gunshot that killed Walter, devastating her and Oliver both.
Felicity returns to the Arrowcave later that night to find Oliver sitting in the dark. Admitting that she'd been doing the same thing, she tries to extend her condolences to Oliver and his family, only for Oliver to tell her that Walter was still alive. He explains that his mother had known who had Walter all along, and he'd followed her straight to Malcolm Merlyn after giving them the news that Walter was found dead. He asks her to pull up Malcolm's phone records to trace the call he made to where Walter was being held, which Felicity discovers is in Blüdhaven. Seeing that the least amount of security is on the roof, Oliver charters a jump plane to parachute down, and when he recovers Walter, Felicity immediately proceeds to the hospital to see him.
In "Darkness on the Edge of Town", Felicity, Oliver and Diggle are trying to figure out what The Undertaking is and how Moira Queen is involved in it. Oliver decides that it's time he spoke to his mother about it, and when Felicity expresses concern due to what happened the last time he tried that, he tells her that he'd be doing it without the hood. When Oliver returns, Felicity is shocked to see the mess his face has become, scolding John and reminding him that he was supposed to pull his punches, indicating that John had told her about the plan Oliver had concocted to make his mother talk. Oliver asks her to research Unidac Industries, to which Felicity reminds him that Queen Consolidated acquired Unidac Industries in the same month they'd met. Discovering that Unidac Industries specialized in seismic infringement, Oliver theorizes that Malcolm plans to level the Glades using a device that triggers a man-made earthquake. Upon finding a news article suggesting that the copycat archer was involved, they realize that the Dark Archer is working for Malcolm Merlyn, and that they were tying up loose ends.
When Felicity decides to hack into Merlyn Global to find information about Malcolm's plan, but is stonewalled by the company's firewalls, she expresses that they would have to waltz in to gain access to the company mainframe. Oliver decides to do just that, and Felicity ends up posing as a delivery girl for the Big Belly Burger and sneaks to the twenty-fourth floor with Oliver. While hacking in, Felicity encounters a guard patrolling the floor earlier than scheduled, and since Oliver is detained by Malcolm himself, John is forced to head up to rescue her, forcing her to pretend to be a Tommy Merlyn groupie. Later, she tells them that she left a Trojan in the mainframe, thinking it would come in handy in the future. The Trojan later alerts them when Malcolm logs onto his computer, prompting Oliver to face him as a distraction while John went to retrieve the earthquake device. However, Felicity's Trojan backfires on her, as Malcolm moved the devices when he discovered the virus.
In "Sacrifice", Detective Quentin takes Felicity into custody for questioning after police technicians find a computer trail linked with the vigilante's activities that traces back to her computer at Queen Consolidated. Felicity is later released when Oliver, as the vigilante, contacts Lance to warn him of the impending attack on the Glades. Before leaving, and without blowing her cover, Felicity explains that she had thought the vigilante was a bad person too, until she realized how much he'd sacrificed for Starling City. She points out that it makes him more of a hero than Lance gives him credit for. Before Oliver leaves to confront Merlyn, he tells Felicity that he wants her out of the Glades because of the chance that the Markov Device would go off. She refuses, telling him that if he's not leaving, she's not leaving. After stealing data from Merlyn Global, Felicity works with Lance to disarm the earthquake device threatening the Glades, blowing her cover with Lance and confirming that she was definitely in league with the vigilante, in order to prevent the Undertaking. Though successful in disarming the device, Felicity was stuck in Verdant as the back-up earthquake device was activated and proceeded to destroy the east side of the Glades.
In "City of Heroes", Felicity and John Diggle travel to Lian Yu in order to find Oliver Queen. In the process, she charters a rickety airplane that she inevitably jumps out of and eventually steps on a land mine, which Oliver saves her from by swinging from a tree using a rope arrow. In a bid to cajole him into returning to Starling City, she reveals that his mother's trial was coming up and Queen Consolidated was undergoing a hostile takeover, which meant that she would lose her job if it succeeded, and that his family would lose the source of their income. She and John convince Oliver to come back, under the condition that he did it as Oliver Queen, and not as The Hood. Later, she, Oliver, and Diggle finally meet Isabel Rochev at QC in regards to the company buyout. The meeting is interrupted by The Hoods, who declare that Oliver has failed the city. As Oliver rushes Isabel out, one of The Hoods members points a gun at him and Felicity hits him with a statue. Oliver and Felicity escape through a window, swinging once again via a chain out the window and into another two floors below, escaping The Hoods. After the attack, Felicity confronts Oliver for not even trying to stop the Hoods, and he responds by citing the body count he typically leaves behind. After Oliver finds out that The Hoods kidnapped Thea, she, Oliver, and John go to the upgraded lair. She helps him find out information about The Hoods, why they formed, and their location. She then gives Oliver his new bow. Back at the hideout, after Oliver defeats The Hoods, they talk about a new way and a new name for The Hood.
In "Identity", Felicity vehemently protests her new job as Oliver's executive assistant despite Oliver's valid excuses. She inevitably stays on as his EA, even though she dislikes her new job. She manages to track where the Chinese Triad strikes next, only for The Arrow to get into an intense fight with Bronze Tiger. Back at the Arrowcave, Felicity called Oliver out on his attitude and told him he was so involved with himself, he didn't realize that Diggle and Carly had broken up, partially because of him. After missing a crucial fundraiser, Oliver becomes vilified by Sebastian Blood, even though he was actually helping the hospital by stopping the Triad from acquiring the next batch of medical supplies being delivered to them. Seemingly to comfort him, Felicity gives Oliver a cup of coffee, stating the word "one" quietly, implying it would be the only time she would get him coffee.
In "Broken Dolls", Felicity and Diggle are waiting in the Arrowcave when Oliver arrives, having been nearly caught by the SCPD due to Laurel setting a trap for him. Oliver asks Felicity to keep an eye out on a new vigilante, a blonde woman who seemed like a highly-skilled fighter, but they soon reprioritize to help Officer Quentin Lance with the Dollmaker case. Because of all the times she hacked the SCPD, they've outsource their evidence to a facility that she can't hack into from the outside. Oliver and Lance break into the facility and give Felicity the connection she needs to retrieve and disseminate the information there, leading to a break in the case. It turns out that all the women used a special type of lotion called Mermaiden, and her skills leave Lance mystified at the thought that she can discover all of that with what little information she's been given in less than a minute, prompting Oliver to smile under the cover of his hood. She then volunteers to be bait for the Dollmaker, going to each boutique and buying Mermaiden. Quentin points out that Felicity must trust The Arrow a lot to be bait for a serial killer. Creeped out, and scared, she vows to never be bait again, right before she's attacked by the Dollmaker. The Arrow and Quentin scare him off, but not before Felicity is injured. When she's recovered, she reports the kidnapping of Officer Quentin and Laurel to Oliver, and manages to provide him with their location.
In "Crucible", Felicity is forced to make excuses for Oliver's lateness at a Queen Consolidated investment party to Isabel Rochev. When asked where he was, Felicity opens her communications link to him, only to be startled at the sound of gunfire. Oliver finally arrives, having some blood on his face that Isabel notices and that Felicity tries to excuse away. While watching Oliver and Laurel speak during the party, Felicity realizes that Laurel had also been in the same two places where the masked blonde vigilante had helped Oliver out, leading her to theorize that it was Laurel, not Oliver, whom the woman was following. This revelation allows Oliver to trap the woman and learn her real identity: Sara Lance. Back at the Arrowcave, Oliver tells Felicity and Diggle that Sara hadn't died on the island, prompting Felicity to question why he hadn't told the Lances about her survival. An upset Oliver explains to her that because nothing good happened on the island, they were better off not knowing. Later, they set aside the Sara issue to locate the Mayor's hideout to take back a stolen weapons crate of military-grade armament. Felicity later "borrows" the FBI facial recognition software to identify the Mayor's real identity, Xavier Reed, and figures out that not only was Reed's foster brother serving in the army, he was also about to hand over assault rifles and grenade launchers to Reed, prompting Oliver to head out and successfully stop it from happening.
In "League of Assassins", Felicity finally meets the elusive Sara Lance and expresses her happiness regarding Sara's survival despite not having known her before the shipwreck. This amuses Sara, who calls Felicity "cute". Oliver tells them that he and Sara were attacked inside Queen Mansion by a man dressed like the Dark Archer/Malcolm Merlyn, then asks Felicity to analyze a bag of dirt the man had tracked in. Hearing their lack of knowledge on the matter, Sara reveals that the man was named Al-Owal, a member of the League of Assassins sent to bring her back with him, as she too was a member. She admits to murdering a man who was inevitably found by his young children and uses it as an example as to why she kept her survival a secret from her family. Later, when Sara apologizes to Felicity for upsetting her with her confession, Felicity compares Sara's regret for joining the League of Assassins to her regret of joining a gym membership. Sara thanks Felicity for not making her feel like "what she was" and expresses how lucky Oliver was for having both her and John as friends. When Oliver arrives, Felicity reports that she'd found pesticide on the dirt he gave her, giving them Al-Owal's possible hideout. After Sara and Oliver fail to deter him, Felicity volunteers to warn Officer Lance about the possible threat on his life. She confronts Lance at his apartment after his shift, and Lance is seemingly disgruntled by not only her request but her vague explanation. Lance refuses to listen to her, believing that he isn't in any real danger. Felicity returns to the Arrowcave, announcing her failure, forcing Sara to reveal herself to her father.
In "Keep Your Enemies Closer", she appears when Isabel Rochev is reprimanding Oliver for his lack of interest in the company. Felicity apologizes for interrupting, reminding Oliver about his "evening plans". She tells him that "Mr. Harper" has information for him while a disbelieving and irritated Isabel listens. Oliver then tells Felicity that she needs to work on her poor excuses. She later goes with Oliver, Diggle, and unexpectedly Isabel to Moscow to rescue Lyla from prison. Unbeknownst to her, Isabel believes she's sleeping with Oliver because of her abrupt job change and asks Oliver multiple times about it. While in the hotel, Felicity helps orchestrate Diggle's capture and coordinates the rendezvous point for his escape. Later that night, Felicity goes to fetch Oliver from his hotel room, Isabel exits his room and tells Oliver that "she can take the night off". Felicity, hurt by what Isabel implied, is visibly shocked by what happened. While she, Oliver, and Knyazev stake out the gulag, Felicity shuts down the prison's phones, helping Diggle and Lyla break out. After the mission succeeds, Diggle, Lyla, Felicity, Oliver, and Isabel later return to Starling City in Oliver's private jet. Despite saying "what happens in Russia stays in Russia" while in Moscow, she confronts Oliver about Isabel at Queen Consolidated, suggesting that she has feelings for him. Oliver replies that it didn't mean anything and that, due to his vigilantism, he believes that "it's better to not be with someone that I could really care about", implying that he may have romantic feelings for her as well, but won't act on them.
In "State v. Queen", Felicity takes Diggle to the Arrowcave when he passes out in the office and immediately calls Oliver. When Oliver arrives, Felicity tells him that Diggle had somehow been injected with Vertigo, and that his condition was the effects of severe withdrawal. The Count, who has broken out of prison, takes credit for the outbreak of Vertigo withdrawal among regular people. As Oliver is occupied with his mother's on-going trial, Felicity works with an ill Diggle to try to figure out why a random mix of people were infected. After plotting out the employment of each infected person, she finds a path and links that path to the free flu shots that were given around Starling City. Since Diggle is out of commission and Oliver is at the trial, Felicity decides to check out the immunization truck on her own, and is subsequently abducted by Count Vertigo. When Count Vertigo finds her Queen Consolidated ID badge in her coat, he manages to figure out the Arrow's true identity and calls Oliver off of her phone, using Felicity as bait to lure Oliver to his office. Despite Felicity telling him not to kill Count Vertigo because of her, Oliver shoots him in the chest three times, killing him anyway when Count Vertigo moves to inject her with a high concentration of Vertigo. Later, Felicity thanks Oliver for saving her life, then apologizes for being the reason he had to choose to kill someone again. Oliver tells her that because she was about to be hurt, "there was no choice to make".
In "The Scientist", Felicity welcomes Moira Queen back when she pays a visit to the office, laughing at the joke Moira makes, but then awkwardly mentioning Moira's stint in prison, making Moira leave the room immediately. Minutes later, she and John fetch Oliver to tell him about a break-in at one of QC's Applied Sciences facilities, where a centrifuge has been stolen. They proceed to the site, meeting Officer Quentin, Kelton the Crime Scene Unit technician, and Barry Allen, who introduces himself as a C.S.I. from the Central City Police Department. After Barry extrapolates a logical, but unbelievable explanation about the thief being super-powered by merely looking at the crime scene, Felicity realizes that he knew more about the case than they did and enlisted his help, telling Barry that Oliver wanted to keep the investigation in-house. During the course of their time together, Felicity exhibits signs of being attracted to Barry, though she was clearly uncomfortable when he mentioned his admiration of The Arrow and his theory that the vigilante had partners, particularly one versed in computer science. Barry seems to reciprocate her affections, and though he was briefly surprised to learn that Felicity spent her nights with Oliver, he is reassured when she denies liking Oliver romantically and then asks him to accompany her to the party Oliver is throwing to celebrate his mother's acquittal. She becomes angry at Oliver when he reveals that Barry has been misleading them, only for Barry to admit that he was investigating their case due to its possible relation to the events that led to his mother's death and the wrongful incarceration of his father. Oliver makes it up to her by reinviting Barry to the party, where they share a dance. Later, after Barry receives a phone call from his boss demanding he return to Central City at once, Felicity is visibly disappointed that they have to say goodbye. She proceeds to the Arrowcave to direct Oliver to the thief's next target, only for the thief to overpower Oliver and knock him into a pile of unknown drugs. Felicity and John come to Oliver's rescue, and when she is unable to discover what Oliver was poisoned with, John decides to call 911, despite Oliver being in full vigilante garb. Felicity stops him from making the call, instead asking John to abduct Barry at the train station to ask for his help in saving Oliver.
In "Three Ghosts", Felicity, John, and Barry work together to save Oliver, with Barry using a small dose of rat poison to thin Oliver's coagulating blood. When Oliver wakes up, he is upset to discover that Felicity has exposed his secret to an outsider without his consent, leading to their first fight which ends only when Barry points out that Oliver was being a jerk to her. While Oliver was away, Felicity runs a print that Barry lifted from Oliver's neck through the computer and finds a match, identifying Oliver's physically-enhanced attacker as Cyrus Gold. As she ran Gold's picture through facial recognition software, targeting traffic cameras to track Gold's location, Barry smugly reminds her about his theory of the vigilante working with partners, and then surprises them by mentioning that he'd kept count of the high-profile cases they'd been involved with. Oliver soon arrives to question Barry about the side-effects of the rat poison, which includes hallucinations and excessive sweating. Felicity correctly realizes that Oliver has been hallucinating and asks what he was seeing, only to be visibly jealous when he mentions Shado, another girl he met on the island. Minutes later, Felicity announces that she had found Gold's location and directs John and Oliver to a motel Gold might be staying in. When Gold manages to hurt John, with him and Oliver narrowly escaping, Oliver tells Felicity to call for backup, and she reaches out to Officer Quentin.
Later that day, Barry implies that despite her denying it, he understood why Felicity would like Oliver. Their conversation eventually turns to their holiday plans, though it is interrupted when Oliver arrives and asks for some privacy, prompting her and Barry to retreat to the Big Belly Burger to get some takeout. They return with John to find the Arrowcave in disarray, though Oliver denies that they'd had a break-in and doesn't explain what happened. After Barry tells Oliver that his hallucinations weren't being caused by any drugs in his system, Felicity finds a police report detailing Quentin's injuries and the death of several officers, including Quentin's former partner and friend, Lucas Hilton. Oliver leaves to speak with Quentin and returns with a key that Felicity tracks back to a place in the Glades. When Oliver prepares to face Gold once more, Felicity tries to stop him and fails, so she asks him to promise that he'd come back, but he doesn't. To John and Felicity's relief, Oliver returns mostly intact, and she rushes to hug him while he assures them that he'd stopped hallucinating, though he also warns them that they had to keep an eye on Roy Harper, who'd been injected with the same serum that gave Gold his enhanced abilities. When he asks after Barry, Felicity tells him that Barry had returned to Central City, just as Barry gives her a call. He tells her that he arrived too late to attend the activation of the S.T.A.R. Labs particle accelerator, but that if she ever decided to go on a date with someone who wasn't Oliver Queen (marking the first time her romantic feelings for Oliver is blatantly mentioned), then that someone wouldn't be late for their date. Barry mentions that he'd left a present for Oliver: a mask. Felicity helps Oliver put it on, becoming the first person to see him as The Arrow. When asked how he looked, Felicity tells him that he looks like a hero.
In "Blast Radius", Felicity has gone to Central City to stay with Barry Allen, who is in a coma. After she returns, Officer Lance asks the Arrow if his "blonde friend" could hack the cell phone records of his fellow policemen to see which one tipped off Cyrus Gold. It is later implied but not directly stated by Officer Lance that Felicity did, indeed, trace the cell phone records of the policemen at the precinct and relayed them to Lance. As Oliver replies, another bomb goes off. He instantly contacts Felicity and she tries to help him find the bomber, Shrapnel. Felicity tracks him while Oliver follows in a high-speed chase. She loses Shrapnel's signal and he ends up escaping. Oliver blames her, claiming she's distracted by Barry. When she angrily leaves, Diggle tells Oliver "I think you didn't have a problem with Felicity's performance until she met Barry Allen". Their argument is still unresolved, a very concerned Felicity helps Oliver escape one of Shrapnel's booby traps by identifying the trap's power source. Afterwards, Oliver apologizes to Felicity, admitting he relies on her more than he thought he did, and acknowledges her as his partner.
In "Blind Spot", Felicity conducts a polygraph test for the Arrow via Bluetooth, determining that the man Oliver was interrogating knew nothing about Brother Blood. At Queen Consolidated, Felicity, Diggle, and Oliver discuss Laurel's claim that Sebastian Blood is not who he says he is. While Diggle is skeptical of Laurel's theory and blames it on paranoia, Felicity seems to think that it's credible and decides to look into it. Felicity researches Blood's past, but is unable to find any electronically-stored information, all of it being held in a file at the City Archives. She assists the Arrow in the Archives, maneuvering him through the building and helping him and Laurel avoid the police when they eventually come.
In "Tremors", Felicity discovers that Ben Turner has escaped from Iron Heights Penitentiary. She explains that since the earthquake, more prisoners have escaped and the prison officials have been working overtime to conceal any breakouts, saying "Iron Heights is better at keeping secrets then they are at keeping prisoners". Felicity later interrupts one of Roy Harper's training sessions, informing the Arrow that Turner has just suspiciously stolen blueprints to Malcolm Merlyn's house. When Oliver returns from the mansion, she fingerprints a watch that he had taken from one of the mercenaries. After scanning several databases, she discovers that the thief in question worked for Milo Armitage, and is ultimately able to track him down based on a shipment that is based at the Starling City docks. When she leaves the Arrowcave and goes upstairs to Verdant to deliver this news to Oliver, Felicity is drunkenly harassed at the bar of the club by a highly intoxicated Laurel Lance. After Oliver's identity is revealed to Roy, Oliver brings him to the Arrowcave. Felicity meets Roy for presumably the first time, and when he asks if their group has a name, she calls themselves "Team Arrow".
In "Heir to the Demon", Felicity discovers Thea's true parentage after questioning Walter about a wire transfer from a flagged account. She asks Walter to talk to Moira about it, but later reveals that she knew he was lying when he said he would. On her own time, she stops by the Queen Mansion and informs Moira of her discovery. Taking advantage of Felicity's feelings for Oliver, Moira manipulates her into keeping her secret, saying that even though Oliver would hate her, he would also blame Felicity for telling him. Moira tells Felicity that "we all have to keep secrets". This ordeal leads her to become distracted and withdrawn, something Oliver notices. Felicity also helps Sara by finding out that the Tibetan Pit Viper venom used for suicidal purposes by a member of the League of Assassins was acquired from the local zoo. She tracks down a license plate that may be connected to Nyssa. At Moira's campaign event, Oliver asks what has been bothering Felicity once and for all. Unable to keep this secret from him, Felicity tells Oliver that she doesn't talk a lot about her family because her father abandoned her and her mother, saying "I barely remember him. But I do remember how much it hurt when he left." She explains to Oliver her fear of losing him. He assures her he won't, which leads her to tell him the truth about Thea.
In "Time of Death", Felicity begins to feel left out as Sara, Oliver, and Diggle trade stories of their battle scars. Felicity takes her frustration out on a training dummy, only for Sara to give her some pointers on self defense. When William Tockman, AKA the Clock King, steals the Skeleton Key, a device that can access any computer system, Felicity tries to stop him, but he manages to divert their attention to stopping a near-collision with a bus and a train. Felicity soon feels insecure and left out again when Sara reveals her aptitude for chemistry and genetics. Together, Felicity and Sara are able to identify the Clock King's disease and manage to put a name on him. Felicity reveals that Tockman's sister is suffering from Cystic Fibrosis and that all the money he steals goes to her. Based on his sister's address, the Arrow and the Canary track him down. However, this proves to be a trap, as Tockman waited for Felicity to hack the device he had planted and was able to backtrack and trace the computer system to the Arrowcave. Using the Skeleton Key, Tockman fries the Arrowcave's computer system. As she assesses the damage, Oliver tells Felicity to call Walter Steele and use some of Oliver's money as bait. When Oliver and Sara leave, Diggle tries to get Felicity to open up about Oliver's relationship with Sara. After Diggle implies that she's feeling insecure because of whatever feelings she has for Oliver, Felicity denies it and explains to Diggle of her uncertainty of herself within the team, feeling extra pressure to take Tockman down. After she puts a large amount of Oliver's money into Starling National Bank, Tockman quickly takes their bait, and Felicity tries to stop him alone. Oliver, Sara and Diggle manage to find her before the Clock King does, but while Oliver deals with Tockman's men and Diggle stops a gas main from exploding, Felicity and Sara find Tockman, only for Felicity to get shot in the shoulder protecting Sara. Using the same virus that fried her systems, Felicity uses Tockman's phone to knock him out. Back at the Arrowcave, Sara patches her up, and Felicity seems pleased that she finally has a scar of her own. It is revealed that Diggle had given her Oxycodone to dull the pain instead of aspirin, as she believed. Oliver confronts her and asks if she was feeling "left out" and a drugged-up Felicity admits that she has gotten used being Oliver's "girl-girl". Oliver reassures her that she will always be his girl.
In "The Promise", when Slade Wilson is in the Queen Mansion on an art tour, Oliver quietly calls Felicity. Bringing back Big Belly Burger for the rest of Team Arrow in the Arrowcave, she answers the call. After there is no response, she believes Oliver butt-dialed her and puts the call on speakerphone. Sara hears Slade's voice and realizes that Oliver and his family are in immanent danger. When the rest of the team leaves, Felicity uses thermal imaging software to track movement Thea, Moira, and Slade while on their tour of the house, therefore directing Diggle, Sara, and Roy on their mission throughout the Queen Mansion.
In "Suicide Squad", the outside of Felicity's townhouse is first seen in this episode when Diggle begins keeping watch on her due to the looming threat of Slade. She comes to his car in her pajamas, gives him a mug of hot chocolate, and convinces Diggle to leave. She tells him that if Slade wants to kill her, he can, and there is nothing Diggle can do to stop him. Felicity is later seen in the Arrowcave, where she explains to Oliver that she is tracking any type of automotive movement in Starling City based on car titles and rental agreements, looking for anything under the name off Slade Wilson. While in conversation with Oliver, she alerts him that an robbery is being held at Fifth and Giffen, saying "We're still in the crime-fighting business, right?" Felicity is also able to locate Slade Wilson's headquarters using information supplied to Oliver by the Bratva. When Oliver plans on meeting Slade at his headquarters, Felicity futilely tries to discourage him, emphasizing that Oliver is no match for Slade and that he'll be killed if he goes.
In "Birds of Prey", Felicity states that she has been "keeping tabs" on Helena Bertinelli's global activity for the last year. She traces a stolen car to Michael Staton, the late fiancé of Helena, hacking the GPS and discovering that she is headed for Starling City. After the Arrow, the Canary, and Roy are unsuccessful in finding Helena, Felicity finds out that a "frat boy" gave her a ride into town and attempts to track Helena down. Throughout the episode, both Felicity and Diggle are very verbally expressive of their feelings for Helena, constantly referring to her as "Oliver's psycho ex-girlfriend".
In "Deathstroke", Felicity gives Oliver a month's worth of phone messages and reminds him about Queen Consolidated's annual board meeting and tells him that there is no way the CEO can avoid attending it. After Thea Queen's abduction, Felicity is adamant on tracking her down. She compiles a list of Verdant's customers from the previous night based on receipts, traces the credit card numbers and connects it to their cell phones, and pings them, looking at all of their photos. When Diggle comments on how much work that is, Felicity simply says, "It's Thea". She finds a partial picture of a car that is registered to Slade Wilson, and hacks into its GPS. Later in the night, when Slade is released from police custody, Felicity leads the rest of Team Arrow over the comms, tracking the car Slade had entered. He somehow multiplies the signal into other identical vehicles, getting away in the process.Felicity attempts to calm Roy down when he gets angry at Oliver and blames him for Thea's kidnapping. She also encourages Oliver when everyone else thinks that it's futile, telling him "Go get Thea. Stop Slade. End this once and for all." Felicity and Diggle console Oliver at the end of the episode, emphasizing to him that he is not alone when it comes to defeating Slade.
In The Man Under the Hood, Felicity masterminds a break-in plan at Queen Consolidated's Applied Sciences division. Using the Skeleton Key, Oliver, Felicity, Diggle, and Sara infiltrate and plant explosives around the building in order to prevent Slade's further use of its technology. When Slade surprises the team in the foundry, Felicity is not hurt or even attacked, but later discovers that he stole the Skeleton Key from them. When Slade breaks into S.T.A.R. Labs, Diggle and Felicity investigate to find out what Slade attempted to steal from them. They run into Cisco Ramon and Caitlin Snow, and Felicity states that she met them before in Central City and asks about Barry's condition. When they refuse to tell her what has been stolen, Felicity hacks Harrison Wells' personal files to find out. She prides herself on doing so, saying "he's the director of S.T.A.R. Labs, which basically makes me unstoppable." Felicity also keeps an eye out on the city's power grid, waiting for the moment Slade activates the bio-transfuser. When Oliver arranges a meeting with Thea, Felicity calls him and interrupts, informing him that the transfuser just went online. She tracks the location but tells him to wait to stop Slade, thinking Oliver's conversation with Thea is more important. Later, when Oliver reveals that there is a cure for the mirakuru, Felicity goes to S.T.A.R. Labs to have an antidote created.
In Seeing Red, Felicity continues investigating Isabel Rochev's death and tells Diggle that S.T.A.R. Labs are still working on the mirakuru cure. Roy destroys her computers after he wakes up and leaves before he can do any more damage. Felicity calls Oliver and Sara (at the same time) with the news that Roy escaped. She helps them track him while on his rampage. She also assists Oliver with his hurt knee and helps him inject an entire bottle of Lidocaine into his knee. Throughout the episode, contrasting with Sara's darker perspective, Felicity emphasizes that Roy can still be saved.
In City of Blood, Felicity attends Moira's funeral with Diggle. There, the pair run into the newly-resurrected Isabel Rochev, who both startles and threatens them. Felicity wonders where Oliver was and why he did not attend his own mother's funeral, and begins looking for him through every means possible. She wonders if Oliver is dead, but learns that he is not when she and Diggle visit Amanda Waller, who informs them that Oliver is at his secondary lair. Felicity and Diggle find him, and when Oliver tells them that he is going to turn himself over to Slade, Felicity tries to talk him out of it. She tells him that if she had accepted things, "I would be a cocktail waitress in Vegas like my mother and I never would have gone to college and I never would have moved a thousand miles away to work at Queen Consolidated and I never would have believed some crazy guy in a hood when told me could be more than just some I.T. girl." He leaves anyway, which causes Diggle and Felicity to take extreme measures. They knock him out, take him back to the Arrowcave, and reveal that Laurel Lance knows his secret. Felicity then interrogates her first victim, Clinton Hogue. Using only her tablet, she hacks into his bank accounts and tediously siphons away enough money until he gives in. Later, stationed in a van rather than the foundry, Felicity directs Diggle to plant a charge that should kill all of Blood's men. Before the charge is set, she reminds Oliver how hard he's worked not to kill anyone. Cisco Ramon then calls her from S.T.A.R. Labs, and she picks up the phone while saying, "now is really not a good time".
In Streets of Fire, Isabel Rochev defeats Diggle and then subsequently asks him where Felicity is, expressing her desire to kill her. She is immediately interrupted by Felicity hitting her with a van. She and Diggle escape and reconvene with Oliver, where Felicity announces that there is a S.T.A.R. Labs courier en route with the mirakuru cure. Felicity calls the courier, only to find that he has been attacked by one of the mirakuru-injected prisoners. She pings his phone, and she, Diggle, and Oliver drive the van to find his location. On their way, however, Slade's soldiers manage to crash the van. Felicity is the most severely injured of the three, being knocked unconscious by a head wound. Oliver carries her until she can walk, but by that time, the cure has already been taken by Slade. They hold base in the clocktower, where Roy is being held. Oliver tells Felicity that he takes blame for what is happening to the city. She tells him that he isn't done fighting because Slade still has to be defeated, and even though she doesn't know how, she knows that, "you are not alone, and I believe in you." When Sebastian Blood contacts Oliver and offers him the cure, Felicity wonders out loud if it's a trap. Nevertheless, Diggle and Oliver both return, and Oliver prepares to test the cure on Roy. At the last second, Felicity tries to convince him not to, warning him of the potentially harmful side affects ("Treat Roy like some kind of lab rat? What if it doesn't work? What if it kills him? What if he wakes up and kills us?"). Oliver hesitantly decides to test it on Roy anyway after they discover that A.R.G.U.S. is planning on leveling the city.
In Unthinkable, Felicity, Roy, and Oliver leave the destroyed clocktower to head to the Arrowcave. While they are working to assemble arrows that contain the mirakuru cure, Roy asks Felicity if he had been unconcious ever since Slade had kidnapped him. She lies to him, telling him "you were out the whole time", most likely to prevent him from discovering how deep the damage had been when he was unstable. Seconds later, members of League of Assassins enter the Arrowcave. There, she meets Nyssa al Ghul for the first time, introducing herself as "Felicity Smoak. M.I.T. class of '09." She then runs into Detective Lance at Queen Consolidated, where she assures Lance that both Oliver and Thea had gotten out of the city safely. When Lance sees Nyssa, the Canary, and the Arrow, he tries to convince Oliver to break his no-killing promise. After Lance leaves, Felicity tells Oliver that she believes Lance is wrong and that murder is not the answer. She reminds Oliver that he has made a promise that he has to keep. She explains that the only reason that Slade is still after him is because Oliver tried to kill him on the island when he had the chance to cure him instead. Oliver tells her that he cannot defeat Slade otherwise, she tells him to "make him out-think you". Oliver unexpectedly takes her to the Queen Mansion, apparently trying to keep her safe. Confused, she asks why. Oliver tells her that he can't have her getting hurt and declares his love for her. He leaves her alone in the mansion, and the audience later finds out that Slade abducted her from the mansion afterwards. Slade calls Oliver and reveals that he has the one Oliver loves most: Felicity. Oliver goes to meet Slade where he is holding Felicity captive. He begins talking to Slade, distracting him, and Felicity, who is being held with Slade's sword to her neck, injects the mirakuru cure into him. Flashbacks reveal that Oliver planned the "I love you" because he knew about Slade's cameras in the mansion and used it as a ploy for Felicity to get near Slade with the cure that Oliver had given her inside the mansion. After Slade is captured, Felicity flies with Diggle and Oliver to Lian Yu where Slade will be held in a secure A.R.G.U.S. bunker. While on the island, Felicity confesses that she believed Oliver's "I love you" for a moment, telling him "you really sold it". Oliver smiles and responds with "we both did." They meet back up with Diggle and Oliver announces that he will fly the plane home. Felicity asks when he learned to fly a plane if he was stranded on the island for five years.
Felicity is an intelligent, ambitious, hard-working, and tech-savvy woman who is highly confident in her computer skills. Though she doesn't go looking for trouble, she is also not one to back away from danger, particularly when there is a mystery waiting to be solved. These traits are proven when she accepts the task of looking into Moira Queen's seemingly blank notebook, despite Walter Steele's warning that the last man who looked into his wife's affairs died suspiciously the next day. In the same scene however, she also reveals a capacity for insecurity in regards to her position in the company, as seen when she assumed she was being fired after Walter called her up to his office. She is also a rather patient and indulgent person, as proven when she continues to humor Oliver Queen's odd requests, despite the obvious lies he provides her with and the dubious and dangerous nature of the tasks he gives her, such as accessing the contents of a bullet-ridden laptop, analyzing the contents of what he claims is an energy drink stored in a syringe, and decrypting a security fob that contained plans to rob an armored car of Blackhawk Squad Protection Group, which Paul Knox claims Felicity was the first person to ever do so.
Aside from her natural talents and developed skills, Felicity's most prominent attributes are her capacity for compassion, kindness, and trust. It is presumably these traits that allows Oliver to trust her with the knowledge of his vigilante activities, as well as rely only on her promise that she would deliver him to his father's old factory after being shot, despite the risk of her alerting the authorities instead. Felicity proves her worth by performing all he had asked of her, and then going beyond what he expected by helping John Diggle patch Oliver up. She then stays at his side with John until he wakes up and, out of loyalty to the then-missing Walter, agrees to join the team to help locate her kidnapped employer. True to her tech-savvy nature, she proceeds to upgrade the Arrowcave's computers simply because Oliver's poorly set up system bugged her. She also helped him cover his tracks by hacking into the SCPD crime lab's computers and to order the destruction of Oliver's blood sample, which was collected by the police after he was shot by his mother.
Initially, Felicity didn't approve of Oliver's harsh methods, especially murdering criminals when necessary, but they ultimately came to an understanding after stopping the Savior. Even though both Oliver and John have tried to prevent the need at times, Felicity has shown that she is capable of handling herself in dangerous situations, having gone undercover in a Mob Casino, infiltrated the Merlyn Global Group headquarters under the guise as a delivery girl, and offered herself as bait to catch the Dollmaker, all to help them take down the criminals they were after. She has been shown training only twice; once with Diggle shortly after joining the team, and once by herself before Sara assisted her.
Conversely, Felicity is also portrayed as a jocular, socially-awkward nerd. She has a habit of babbling without censoring herself, and usually does so using double ententes with sexual connotation. This happens when she is nervous, particularly in the presence of authority figures (such as Walter Steele and Moira Queen) or those she finds attractive (like Oliver Queen and Barry Allen). Her trademark babbling often results in her feeling embarrassed, so she tries to backtrack and explain herself, which only contributes to her rambling. The exception to her embarrassment seems to be Barry, though neither of them seem to notice when she does it. But despite her tendency to babble, she isn't afraid to give voice to her opinions, and she always stands her ground unwavering when she knows she's in the right. Felicity uses humor in any type of situation, especially darker ones where her comical yet positive outlook on life usually relieves the tension. One of her strongest attributes is her ability to surprise others that underestimate her, such as Clinton Hogue, who scoffed at the idea of Felicity interrogating him, or Slade Wilson who thought Oliver "had a thing for stronger women", only for Felicity to be the ace in the hole in his own demise.
- Genius-level intellect: Felicity is an intellectual whizkid, as evidenced by the crucial role she plays in Team Arrow, as well as her enviable skillset in tasks such as information retrieval, computer software and technology, and the creation of customized gadgets, among other things. She was able to draw an accurate theory regarding Oliver's alternate identity from the few requests Oliver asked of her which would later be connected to the vigilante's activities, but she did not expose his secret identity to anyone, nor did she mention it until Oliver entrusted her with the information. Felicity hints at being scientifically proficient from an early age (claiming to have been engineering computers since she was 7), which is a recurring trait among child prodigies. She is also an adroit card counter, telling Oliver that "it's all probability theory and mathematics". When Felicity infiltrates an illegal casino in "The Undertaking", she is so adept at winning card games that she was immediately reprimanded by the owner, who was under the impression that she was cheating. She has a superior memory, and is an expert engineer, showing her prowess in disabling both bombs and the Markov device. She also hoards and displays intimate knowledge in many other subjects, such as history, politics, economics, geography, physics, engineering, biology, and chemistry.
- Computer specialist: As an M.I.T. graduate (class of 2009) and a former member of Queen Consolidated's I.T. department, Felicity has proven herself to be a highly skilled computer specialist. She was able to recover valuable information, such as the blueprints of the exchange building where the Unidac Industries auction was being held, from Floyd Lawton's damaged laptop, despite the fact that it had sustained bullet holes. She was able to find the delivery location of a teflon-coated titanium blade arrow by tracking down its manufacturing company, Sagittarius, and finding out where and when it had been purchased using the company's records. She analyzed a sample of the drug named Vertigo and was able to find its manufacturing location in the city. After discovering the vigilante's identity, Felicity constructed a highly effective computer system in the Arrowcave, which she uses to locate people, places, and things Oliver has a problem finding on his own.
- Expert computer hacker: Felicity is a highly-skilled computer hacker, capable of breaking into any computer system, which makes her a valuable asset to Team Arrow. She was able to hack into the crime lab computers of the SCPD and order the disposal of the vigilante's blood, which had been lifted from a crime scene for analysis. She also managed to easily hack into A.R.G.U.S.'s databanks in order to track Deadshot's movements and broke into Harrison Wells' (the director of S.T.A.R. Labs) personal files. The only computer system which proved immune to her skills was that of Merlyn Global Group, but this was remedied with the help of Oliver and Diggle, who snuck her into Merlyn Global's headquarters so she could gain direct access to their mainframe. She then proceeded to download the entire schematics from the Markov Device, and planted a Trojan in the system, so they would know what Malcolm was up to. She is more than able to bypass most firewalls and is also able to do so with surprising speed.
