Pete Wentz wanted for the dumbest crack fairy tale line where Prince Patrick needs to be rescued from a tower guarded by a dragon and Accoucheur Pete needs extra money so he takes the job and fucks up so badly that Patrick has to save himself and Pete. Cue adventure times to travel back to the kingdom. Think Shrek, with less ogres and interspecies sex (or more, who knows, I'm not tryin' put a cap on anything here).
Or another AU. Or a canon line. I'm not really picky.
