Yeah, I know his appearance was minute, but I think he has a lot more character than some of the current espada. I agree with Rukia making the Soul Society arc fail miserably, but if you could ignore her, and you looked back at things, you realized "OH, this connects to THIS later on, and this is part of blahblah's coat, how could I miss this?!?!" etc, and you realized that Kubo had it all planned out so well, and put hints in waaaay early on. I'm still in denial and hope Kubo will do something amazing with the current plot and make everyone go "D'OH!" like with Aizen; but I know it's just wishful thinking.
