Yeah, bothered about the 'Darkness of FT' thing too, but I'll wait till we get more info on that. It might be that the nature of the reasons for putting Mavis in stasis might be ambiguous, rather than LH itself being something dark. Many things could still fit.

But, yeah, I also think that Mashima changed his take on this after creating Zero. Like 'Kyouka knows Silver has a Demon form' makes me think that Mashima also changed the Silver story at the last moment, kind of thing. I just hope he does better than that. >.>
