Unohana and Zaraki are currently fighting in lowest prison level, the same place where Aizen is imprisoned. So, do you think this battle will set him free? That kinda seems to be Kubo's intention. It will be very interesting if this happens considering the fact that he's been labeled as one of five great war potentials, meaning there are aspects to his power not yet revealed. What do you think Aizen will do after he escapes? Will he join either of the sides or try to use the conflict for his own goals?
