Well, he did answer the “Who’s Ralph?” question the fans had. And his name seems very witness protection to me. Maybe this was Disney testing the waters to see if non-comic fans wanted to see the X-men with the Avengers characters.
Other side of the coin is his Quicksilver is in the same time line as Apocalypse, Dark Phoenix, and New Mutants. I don’t think we want that timeline to exist. Also, Logan has a definitive end for the Mutants we’ve known over the decades.
Now, if Monica’s Astrophysicist friend does indeed turn out to be Reed Richards, that’s gonna be awesome.
Side note, I’ve been enjoying the Vishawn memes way too much.
