Behind the scenes

  • After Laurel sidesteps around using Felicity's name, Oliver claims that she's "not Voldemort", a reference to the main antagonist of the Harry Potter series.
    • Thea additionally makes fun of Oliver for actually having knowledge of Harry Potter. He claims to have read a few of the books and is surprised that there are films. Not all of this can be attributed to Oliver's time spent on Lian Yu, as he was first stranded there on 2007, where five of the films had already been released.
  • Curtis compares the projected price of the bio-chip to the first Digital Equipment Corporation VAX, a high-end minicomputer from the late 70s.
  • When Thea bursts into Felicity's office just after the latter's mother, she claims that they are like Tribbles, creatures from the Star Trek franchise which are known for their often-excessive reproduction rate.
  • When Curtis sees the Arrowcave, he exclaims "holy frak", a reference to an expletive popularized by the Battlestar Galactica franchise.
    • This same exclamation is frequently used by Cisco Ramon.
  • Curtis compares the robotic bees hitting critical mass to "John Hurt in Alien", referencing the actor's character in the 1979 film, Gilbert Kane, who is killed by a chestburster.
  • Curtis asks Laurel to use her Canary Cry by giving it "the full Mariah Carey".
  • When Donna sees the secret elevator in the Palmer Technologies building, she likens it to the 2002 Jodie Foster film, Panic Room.
  • Brie Larvan mentions her "favorite scene from My Girl", likely referencing a scene in which the character Thomas J. Sennett is fatally stung by a bee.
  • The episode's title is mentioned a number of times later in the episode, referencing Team Arrow's need to be a beacon of hope for others, as no one else is, as well as being one of many bee puns featured in the episode.
  • Felicity reminds Thea that they are in a "Die Hard movie with bees", referencing the film series that have been a favorite for Stephen Amell.
  • After Curtis comes up with the idea to upload a virus to the collective of bees, Lance likens it to the 1996 film Independence Day, in which the characters upload a virus to the alien mothership, allowing them to implant a nuclear bomb (effectively decimating the enemy).
  • Curtis calls Larvan "Bea Arthur", an actress.
  • When Paul goes to heat up soup for Curtis, he describes it as "terrific", referencing his comic book alter ego Mr. Terrific.
  • The end of the episode includes info on the Christopher and Dana Reeve Foundation due to its subject on Felicity and Brie both dealing with paralysis. Following the airing, The CW released a special PSA from Emily Bett Rickards and a representative from the foundation.
