Thea Dearden Queen (born January 21, 1995) is a wealthy 18 year-old girl. She is the birth daughter of Moira Queen and Malcolm Merlyn, the step-daughter of the late Robert Queen, the younger half sister of Oliver Queen and the late Tommy Merlyn, a good friend of Margo, Blake, and Morgan, and the girlfriend and love interest of Roy Harper. Before she met Roy and began a romantic relationship with him, she had a crush on Tommy Merlyn, who unknown to her was her half brother, and Shane Colvin.
Thea is the daughter of Moria Queen and Malcolm Merlyn. Thea (it is insinuated) idolized Oliver as a child. They used to be close and, according to Oliver, she used to chase after him when she was younger, thus giving her the nickname, "Speedy". When her father and brother were both presumed dead, Thea felt alone and disconnected from the world. She fell into a life of drugs and partying to fill the void left by her father and brother. Oliver's reappearance has done little to fill that void, as he is hardly ever around to re-connect with her. After a string of "disappearances" and a murder charge, Thea herself is starting to wonder where Oliver "disappears" to.
In "Pilot", Thea was one of the first people to welcome Oliver home with open arms. Though she is later surprised and disappointed when Oliver expresses his unhappiness with her party lifestyle, which Oliver himself used to lead.
In "Lone Gunmen", Thea is brought home by the police after a night of drunken partying that led to breaking and entering a shop. Despite being grounded, she parties at the nightclub Poison, where she bumps into Oliver, and the two have an argument.

Later on she is with Moira at the hospital and later seen telling Oliver off for leaving Moira and going after the shooter. Thea stays in that night with Moira after Oliver tells her he has a buisiness meeting, talking to Moira how she wishes that Oliver wouldn't lie and tell them what's wrong.

In "Vertigo", Due to the rampant use of Vertigo in Starling City, the judge overseeing Thea's trial decided that the best way to discourage the drug's use is to sentence Thea to hard time, by showing that not even the rich can escape the law. Oliver decided to take down The Count so as to take heat off her. He also talks to Laurel about getting her father to use his connections to help Thea. Detective Quentin Lance was able to get Thea a deal where she had to work community service for 500 hours, and be under the watch of a guardian, Laurel. The plan was for her to work at CNRI. Thea refuses the deal just to spite her mother, who she thinks is cheating on Walter and cheated on her birth father, as well.

When Verdant later got attacked by The Hoods, looking for Oliver, Roy made an attempt to fight the attackers, to no avail with The Hoods kidnapping Thea in the process. While in captivity, when The Hoods argued what to do with Thea, Thea realized that Moira was a victim of circumstances and that she had no choice but to follow Malcolm due to her fear of him.
