Does anyone know why Osric Chau was called Ryan Choi instead of Alternate! Kevin Tran? Supernatural has alternate universes, including Earth negative-several-zillion, where the brothers are stars on a cheesy TV show,
Also, why did no one say, "Would you rather hug your wife and child while they die, or try to save them?" CWverse motivation often boils down to, "you should do this because my life sucks too".
I'm pretty sure that the ending to this crossover will be Ashton Kutcher awaklening John Cryer on "the couch" and telling him that he was having a bad (or good!) dream. That, or obvious time-travel shenanigans.
