In 2010, John Welsey Shipp provided the voice for Professor Zoom/The Reverse Flash in the Batman: The Brave and The Bold episode "Requiem for a Speedster" (which centers around The Flash).
According to the Social Security card in Barry's wallet, his Social Security number is 547-29-6400. This number did belong to a real life individual by the name of Zabel Aivazian who died in 1987.
Scudder: You know, some things I'll put up with. But getting double-crossed by the woman I love is definitely not one of them.
Barry: Tina, I've never seen you like this. What's the matter?
Tina: What's the matter? Nothing's the matter. It's only the end of the world as I know it.
Barry: Don't you think you're overreacting a little?
Tina: You don't know my mother.
Jocelyn: And what do you do, Barry?
Stasia: I don't believe it. Barry Allen? (kisses him)
Jocelyn: I see that you do rather well.
Jocelyn: There are research firms in more civilized cities. Like New York.
Tina: Central City has a lot to offer, Mother.
Barry: That's true. Did you know the corn dog was invented here? (Tina and Jocelyn stare) Uh, yeah, okay. Wow, look at the time.
Stasia: What, are you and Tina...?
Barry: Just friends. We're intimate yet platonic.
Stasia: You know something? You really are a nice guy.
Tina: Barry, who was that?
Barry: Oh, I, um, I did her homework in high school.
Tina: You did her homework or you were her homework?
The Infantino Hotel, mentioned in previous episodes, is said to be at the corner of Fox & Broome. Gardner Fox created the Golden Age Flash, Jay Garrick, in 1939 and then updated the concept and created the Silver Age Flash, Barry Allen. John Broome wrote the first Barry Allen Flash story, "Mystery of the Human Thunderbolt!" in Showcase #4 (Oct. 1956).
Jocelyn holds her reception at the Garrick Gallery, another reference to Jay Garrick, the Golden Age Flash.
The original Mirror Master first appeared in Flash v. 1 #105 (Feb-March 1959), and was created by John Broome and Carmine Infantino. Samuel Scudder was a small-time crook who became fascinated by mirrors and created a number of mirror gimmicks. Dubbing himself the "Mirror Master," Scudder pitted himself against the Silver Age Flash and numerous other heroes, and was a charter member of the original Secret Society of Super-Villains. He was killed during Crisis, however, An orphan, Scotsman Evan McCulloch, turned to crime and government agents hired him to work for them and provided him with the equipment of the original Mirror Master. Scudder hires himself out as a mercenary, although he can often be swayed by sentiment toward orphans or hired away by someone offering a higher price. Since the 2011 reboot of DC comics, the Mirror Master has reverted back to Scudder.
Scudder: I love Double Jeopardy.
Scudder is referring to the long-running gameshow Jeopardy!, where contestants must provide their answers in the form of a question. The game is divided into three rounds, and the second round is called Double Jeopardy since the points for the five correct answers in each category are double ($200 - $400 - $600 - $800 - $1,000) the value of those in the first round.
Murphy: Now it's The Flash and Pecos Bill.
When hearing about the cowboy in the middle of the street, Murphy describes Pecos Bill, a legendary fictional cowboy created by Edward O'Reilly in 1917. Pecos Bill was raised by wolves, used a snake as a lasso, and dated Slue-Foot Sue. Patrick Swayze portrayed the character in the 1995 movie Tall Tale.
Stasia makes reference at least twice to Professor Zoom in this episode. In the comics, Professor Zoom is from the future and is one The Flash's recurring villains.
