Eh - they better not do a 'baby' storyline - fake or otherwise, but I won't be shocked if they do! It WILL kill my interest, though, I know that for a fact if they go that route. They already created one writing disaster, no need for another one.
As for the DE route, Daphne is pretty strong and opinionated, if the friendship is effected, it would be to Emmett's own doing. I don't see Daphne respecting what he did at all, I just don't.
