However, by the season finale, fans were disappointed to learn that Peters wasn't actually Quicksilver, but rather a red herring/phallic joke. Upon closer inspection, though, there are several clues that indicate that "Ralph Bohner" may indeed be X-Men's Quicksilver.
The Multiverse Saga is in full swing, and with it has come many cameos in the first two years of Phase 4. From Tobey Maguire and Andrew Garfield returning as their versions of Peter Parker, to Patrick Stewart returning as Professor X, fans have been treated to cameo after cameo.
It makes little sense for a fan-favorite such as Evan Peters to be used for a subpar joke, rather than utilizing him long-term. Quicksilver, along with the other X-Men, are fair game for Marvel Studios now that they own the rights to the franchise once more. It would be a shame if Marvel let the opportunity to use him as a true Quicksilver variant go to waste.
