Hahahaha, Halibel dies, and by Aizen's hand
The one character I'm most disappointed in is Gin. So far, he's been acting as nothing except Aizen's lapdog. I always saw him as a very individualistic schemer who sticks to whichever side is more likely to win, or just does things for his own sake. I'm still waiting for him to "explode" so I'm still hopeful.
On another note, I'm still hoping nobody else disappoints me as greatly as Soi Fon did with her childish behavior and her Bankai. I'm serious, if Kensei or Urahara end up having a Bankai that makes no sense, especially after all the hype behind Urahara's possible Bankai, I'm going to stop reading this.
