i've added a citation for epicurus being the originator of the problem of evil there's probably a better one available somewhere but this one will do for now not sure whether you were looking for a cite for the theory as a whole or not i don't see a lot of mainstream media discussion of the alternate ending theory except for maybe this article in the oregon herald a publication with which i am unfamiliar but there's plenty of discussion of it in online sources reviewers and blogs message boards etc as such it's not original research but it'd be nice to have a firm print citation if someone can find one
