Uhm... I don't quite see how it makes sense but I'm not like.. totally opposed to it either.
Hm... it took me a long while to not hate, Gajeel...
Anyway, now we have Logia users in FT... I guess. And more split personality. Wait, I just recall something! Zeref! Not "cuddle me Zeref" from Tenryou but Jellal-possessing Zeref from way back in the beginning. Or part of Zeref or whatever that was in the end. Or is Rogue really just nuts? (And apparently Gajeel remembers... stuff. Well, I'd assume Rogue looks a lot different than as a kid(?)
