Thea: It's shocking that you know who Voldemort is.
Oliver: Well, I mean I'm not immune to pop culture. I read a few of the Harry Potter books.
Diggle: Really? I was going to bet Thea that you just saw the movies.
Oliver: There were movies?

(to Donna)
Felicity: Oh, my God, I don't know what's worse--the fact that you just spelled out breakup or that you misspelled it.

Curtis Holt: Do you guys even know what that is?
Quentin: That is an army of robotic bees. Yeah, that's my life now.

(about Curtis)
Diggle: It looks like we have ourselves a taller, more dude-like version of Felicity.

Curtis Holt: But I'll have to "bee" careful. It's too soon for bee puns, right?
Oliver: Let's assume that it is.

Donna Smoak: They just got their butts kicked by that--that--that bee man.
Felicity: This is why we leave the nicknames to Cisco.
Thea: Yeah.
Donna Smoak: What?
Felicity: Inside joke.

Donna Smoak: Um, don't you think you should have thought of that, like, I don’t know, 15 minutes ago?
Felicity: Oh, I'm sorry. I was busy trying not to die, and you were talking, talking, talking.

Oliver: That was inside me?
Curtis Holt: Well, that and thousands of its microscopic larvae. Don't worry. Should pass in a few days.
Oliver: Can't wait.

Curtis Holt: But we just beat a group of robot bees using a superhero doohickey, and if that's not high-five-worthy, I don't know what is.

Quentin: Like what they did in Independence Day, right? (everyone stares) What, I can't watch movies, too?

Curtis Holt: That's both comforting and horrifying at the same time.
Oliver: Yeah. Welcome to our world.

Oliver: Laurel, she's not Voldemort.

Voldemort is the evil wizard, originally named Tom Riddle, who is the nemesis of Harry Potter in J.K. Rowling's Harry Potter novels.

Felicity: You people are like tribbles today.

Tribbles are small furry fictional creatures found in the Star Trek programs, starting with "The Trouble With Tribbles" in 1967. They multiply rapidly when overfed

Felicity: Just when I thought I was out.

Felicity paraphrases the aging Michael Corleone in the movie The Godfather Part III saying the same thing.

Curtis: The damn things are like the Borg.

The Borg are cybernetic humanoids from the Star Trek franchise that share a collective consciousness.

Curtis: It's gonna be like John Hurt in Alien!

In the movie Alien (1979), John Hurt plays Kane, a crewman who is "infected" by an alien egg. A small alien bursts out of his chest in the middle of a meal.

Donna: Whoa, so this is like that thing, from that, uh--that Jodie Foster movie.

In the 2002 movie Panic Room, Jodie Foster plays a desperate mother who takes refuge in a panic room in the new brownstone apartment that she has just bought, when burglar break in looking for bearer's bonds.

Brie: I want the microchip specs, or your friend relives my favorite scene from My Girl.

In the movie My Girl (1991), one of the main characters dies due to an allergic reaction from a bee sting.

Felicity: Thea, we're in a Die Hard movie with bees.

Die Hard is a 1988 movie starring Bruce Willis as John McClane, a New York cop visiting his estranged wife in California on Christmas. Apparent terrorists take over the skyscraper that he visits, trapping him in the building and forcing him to fight back.

Quentin: Like what they did in Independence Day, right?

In the 1996 movie Independence Day, a computer programmer sabotages an alien ship by uploading a virus into its computer system.
