Actually, if you'd played Resi Gaiden, you would know that it was all a dream and never actually happened.

I do want to see stuff happen in RE5, just that most of the characters have been cut out already so there's not many left to work with.

Realistically, it could only be Chris and Claire, since they're kinda after Wesker, but even then...

There are hints that Sherry will appear, either as a main character or a villain though.
