Like many people, we didn’t see that coming: that shock ending to WandaVision‘s fifth episode.

[MAJOR SPOILERS after the jump!]

In case you missed it on Disney+, the WandaVision episode ended by revealing Wanda Maximoff’s brother, Pietro Maximoff, being alive and well!

Now, this is a shocker because – as far as the Marvel Cinematic Universe (“MCU”) is concerned (of which WandaVision is decidedly a part of!) – Pietro Maximoff died saving Hawkeye in Avengers: Age of Ultron; and he was played by actor Aaron Taylor-Johnson.

Now, to add to the shock factor, the Pietro that was shown at the door was played by Evan Peters; who acted as the Quicksilver we see in Fox’s X-men movies: Days of Future Past; Apocalypse and Dark Phoenix.

So, not only is Wanda’s brother Pietro alive again – the version of him that is alive is from a completely different universe, namely Fox Studios’ “X-Men/mutant universe” – which hasn’t been a part of the MCU… yet.

So, what does this mean? Well, it could mean a lot of things – and that’s why everyone’s buzzing!

Since the Disney-Fox merger two years ago in 2019, fans have been anticipating when or if mutants and the X-men would make their way to the MCU. This could be the first real instance of the possibility becoming a reality!

Also, coupled by the fact that the MCU’s Scarlet Witch will have a role in Doctor Strange in the Multiverse of Madness – keyword being “multiverse” – it’s no wonder fans are going bananas over the, ahem, multiple possibilities. After all, Elizabeth Olsen, who plays Wanda in the MCU, did say that Scarlet Witch’s role in the Doctor Strange sequel will feel earned after WandaVision:

And now, I’m excited for the next thing… I just signed on because I liked the character, because of the comics, and I thought the Age of Ultron story was really powerful and fun, angsty and rebellious, and really an honorable story to tell. Now, it’s this completely new thing that it never was at the beginning. The transition from WandaVision to Doctor Strange 2, I just feel like it’s all so earned.

Even though the hype is very real right now, we’re still holding our breaths to see where this all goes. Having Evan Peters’ Pietro show up in the MCU could be the beginning of a lot of things, or it could be a nice little hat tip and fan service that ultimately amounts to little more than that.

Where do you think this will go?
