aizen is definately one of the best villains ever seen in anime history, at first in the manga, it was so unpredictable, the last guy to ever think about being a villain actually a villain. one of them is going to have their ass handed to them in my opinion, and i'm not talking about gin or aizen, just guessing. this episode was worth waiting 2 weeks.
i just want to see gin's bankai, is that so much to ask? and if he does release his bankai, i'm placing bets on a shotgun, because shinsou looks like the type of sword to be used while faraway, like a sniping mission and gin tends to disappear a lot..
