Well, who saw this coming?
Uh, most of us actually, as it's been reported that Evan Peters would appear in WandaVision for upwards of a year now. However, the reveal that Wanda has seemingly "recast" her brother (as we predicted here on CBM) still came as a surprise, and seeing the X-Men: Days of Future Past, X-Men: Apocalypse, and Dark Phoenix star return as Pietro was a definite shocker.
It's left us with a lot of questions...and even more theories. Wanda appeared to be surprised, so has she or someone else plucked this Pietro out of the Multiverse as a replacement for her dead brother? Could Peters actually be playing a random Westview resident who has been forced into the role?
We still haven't learned who Jimmy Woo's mysterious witness is, so it's feasible - as CBM member contrast has suggested - that's who Evans is playing (potentially with the reveal that he's either Simon Williams/Wonder Man or Eric Williams/Grim Reaper). If that's the case, it'll likely be revealed next week.
Marvel Studios certainly knows how to get us talking, and if this Pietro reveal isn't handled the right way, fans are either going to be overjoyed...or thoroughly disappointed.
