Yeah, and then the shit hit the fan.Hmm? struggle? To what extent?
Oh, you mean "No... you won't use me for this!". I was thinking of when XH was telling Riku "You must become stronger" and so on. He didn't struggle there; he willingly opened his heart to Darkness, soething that would normally end in the person becoming a Heartless, but in Riku's case, XH took over his body and became whole.
Hmm, Kingdom Hearts is pretty complkicated when you get down to it.
