Dude, I haven't seen the latest season yet, but who WOULDNT be changed by all the stuff they've been through. I think one of the cool things about the show is that it stuck out to me as different than many anime you see, where the characters are somewhat static. I will brush up on the latest episodes before I comment more on it, but I think character change is a great thing to include in a series. Plus there is still time for them to change again. Wouldnt that be cool, if they lose touch with who they were, just to get reinvigorated later? Id like to see that.
