Notes
- Punk artist Kathleen Hanna performed this episode's intro theme, "Let's Keep it Going," along with Kristen Anderson-Lopez, the co-writer/producer of all the series' intro themes.
Trivia
- This episode pays homage to the early 2000s sitcom Malcolm in the Middle with its intro and with how Billy and Tommy Maximoff talk directly to the camera.
- Pietro references the iconic shower scene from the 1960 film Psycho when pretending to stab Billy and Tommy.
- The entire Maximoff family wears Halloween costumes that are extremely accurate to their respective comic book counterparts' superhero outfits.
- Pietro tells Billy and Tommy, "unleash hell, demon spawn!" This is a nod to Billy and Tommy Maximoff originally being fragments of Mephisto's soul in the comics.
- Tommy and Pietro say, "I feel the need... for speed," referencing the 1980 film Top Gun and Tommy's comic book alias, Speed.
- Wanda lingers on Pietro's use of the word "kick-ass," which could be a nod to the fact that both Quicksilver actors Evan Peters and Aaron Taylor-Johnson (from Avengers: Age of Ultron) both appeared together in the film Kick-Ass.
- The movie theater marquee shows that the superhero family film The Incredibles and the 1998 remake of The Parent Trap are playing in Westview.
- S.W.O.R.D. has a file on an individual named "Ray Johnson," which could be a reference to the character John Wraith, who went by the alias Ray Johnson in the comics.
- Night of the Living Dead is being projected onto the big screen in the town square.
