Warning: Spoilers for “WandaVision” episode 5 below.

The ending of the fifth episode of “WandaVision” had a cliffhanger that might have seemed confusing for some. But it’s actually a huge deal when you consider the Marvel Cinematic Universe and where it’s heading next.

What happened

The latest “WandaVision” episode ended with Wanda (Elizabeth Olsen) opening her door to see a silver-haired young man standing in the doorway. He introduced himself as Pietro, the brother of Wanda who died in “Avengers: Age of Ultron.” Wanda had said previously in the episode that people can’t be brought back from the dead.

  • However, there was a noticeable difference. Her brother Pietro — who is the superhero Quicksilver — did not look the same as he did in “Age of Ultron.”
  • In fact, Darcy Lewis (Kat Dennings) said while watching the “episode” of “WandaVision” that Wanda had recast her brother with a different person. That’s because real-life actor Evan Peters replaced Aaron Taylor-Johnson in the role.

Why it matters

Evan Peters played Quicksilver in Fox’s X-Men franchise. But Quicksilver was played by Aaron Taylor-Johnson in “Avengers: Age of Ultron.” We get the sense that Wanda “recast” her brother Pietro at the end of the episode, which suggests that Peters will likely play the role moving forward.

  • This represents the first time someone from the X-Men franchise has joined the Marvel Cinematic Universe since Disney purchased 21st Century Fox and its film properties.
  • “This is the first major step for Marvel Studios incorporating elements of the X-Men franchise. Where it goes from here is anyone’s guess, but the stars of ‘WandaVision’ have seemingly been teasing this moment for a long time,” according to ComicBook.com.

Is this the ‘Luke Skywalker moment’?

“WandaVision” star Elizabeth Olsen recently told TVLine that the Disney+ Marvel show will have a “Luke Skywalker moment” — meaning a character from the past returns in the same way that Luke Skywalker returned at the end of “The Mandalorian” Season 2 finale.

Vision actor Paul Bettany told Black Girl Nerds that a surprise actor will make an appearance on the show, too. It’s unclear if he was referring to Peters, though.
