I agree that was a good fight. Much better than the others we've seen recently. Hutsogaya wasn't bad at all, but with Hinamori unconscious on the ground I think he was at a disadvantage. Either he is forced to protect her, or if she was killed he would likely be too shocked/upset to be able to fight properly. If Matsumoto hadn't shown up he'd have been screwed. Oh, and the blond guy was completely useless.

I think there was a breif flashback showing Gin saving Matsumoto's life, but we still don't know why he cared about her getting hurt and stopped the fight. Bit of an odd note, since most of time he gives the impression that he'd love to laugh while watching everyone else die horribly.

I'm interested to see next week who Ichigo was in soul society before he died there and was reincarnated as a human. I think Ganju's brother is a good guess, but if that were true than you'd think that Ganju or his sister would have noticed the physical resemblance the same way Rukia and Renji did. I suppose that could be a plot hole, but I'm guessing he was someone else.
