[MS] Regarding Juvia in chapter 499

So i've seen in other subreddits, other forums FT related and including 9gag people saying that juvia will ressurect because of "nakama power" or because Mashima feels like bringing her back but here is my theory if we think about it correctly it makes kinda of some sense so here it goes.

Remember Juvia saying that her body is made of water?

Yes that's the whole reason why i believe she is still alive and never died in the first place. We have seen in first hand that Invel's Ice Lock does not deny the usage of magic so what i believe it happened is that Juvia penetrated her body with her magic but her body was in water form so it didn't affect her at all.

And where did all of that blood came from when she "sacrificed" herself you might ask.

Well simple answer, her new magic that she learned to save Gray in case of need (she can either control blood now or transmute water into blood something like i cant remember very well right now).

So yeah that's my theory, tell me what you guys think and correct me if i'm wrong at some point or if i've forgotten something.
