WARNING: The following contains spoilers for WandaVision Episode 6, "All-New Halloween Spooktacular!" now streaming on Disney+.

Disney+ series WandaVision's retro-throwback aesthetic perfectly parodies classic family sitcoms with just enough oddities to signal to fans that not everything as it seems. The mystery behind WandaVision has captivated fans and theorists alike, with many fans digging through every episode for any hint towards what exactly is going on.

One particular reference caught the attention of Redditor kidkolumbus on the TVDetails subreddit. In episode 6 of WandaVision, there's a scene where Wanda's twins, Billy and Tommy, are playing Dance Dance Revolution. More specifically, they're playing the song "Butterfly" by smile.dk which is a song featured on earlier versions of DDR and often associated with the rhythm game. However, it may factor into yet another ongoing piece of symbolism for the series: butterflies keep appearing.

"Butterfly" itself is notable as it introduced a new technique to DDR called the Butterly Spin/Turn, which forces players to quite literally turn around on the dance pad to hit the notes. This scene was brought up on the TVDetails subreddit due to the fact that one of the twins fails the song and falls down trying to perform Butterly Spin/Turn. kidkolumbus was able to identify what was happening during the scene as it was something so common and specific for himself and other DDR players.

"Butterfly" is so specific a reference, though, that it could be more than just a nod. Butterflies have been a notable part of WandaVision since the first episode. Butterflies were present on Wanda's calendar, and since then have appeared in other notable scenes, such as when Wanda's magic began to falter while pregnant. Fans have been speculating as to what they mean for the series as a whole.

Layla Miller is the girl who knows stuff

One popular theory relates to a character that Scarlet Witch has had plenty of interaction within the comics. Layla Miller, otherwise known as the Butterfly, is a mutant from Marvel's comics whose mutant ability allows her to coexist within alternate realities. In short, Layla retains the knowledge of any timeline that branches from the main one. She can also give other people knowledge of their lives beyond the reality they're currently in, which helps her free people from an alternate reality that Scarlet Witch created in the comic storyline House of M.

Fans think that Layla Miller may make her debut into the MCU by helping to break people out of Scarlet Witch's false reality that she's created. Granted, there are so many references to characters who have yet to appear in the MCU some fans have dismissed many as red hearings, but this may one of the few clear-cut hints towards the shows ending. The use of the song "Butterfly" and the Butterly Spin/Turn technique may be a hint towards what these butterflies really mean.

The writers could be specifically hinting that the big "spin" or "turn" for the series is directly related to the butterflies and possibly even Layla Miller. The Spin/Turn technique causes one of Wanda's twins to fail the song, which could be further proof that the butterflies are disrupting the illusion. This may be a stretch, but butterflies have been used before to break character out of illusions as well. In Doctor Strange, Strange ends up falling out of his multiverse-spanning mind-trip after seeing a butterfly approach him.

The DDR easter egg in WandaVision may be indicating to fans that butterflies may be what helps "turn" the people trapped in Wanda's illusion away. There's also the lyric in smile.dk's "Butterfly." "Green, black and blue, make the colors in the sky." Given that most of WandaVision takes place in a black and white reality, the butterflies may literally bring color back to this reality, breaking Scarlet Witch's illusion.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau and Kathryn Hahn as Agnes. New episodes air Fridays on Disney+.
