Just read chapter 489 of Bleach and was going along fine. Then I saw Hinamori. Or at least I'm assuming it's Hinamori since her face was about the same and she was at a fukutaichou meeting (love Kira's new hair!). Last I saw she got stabbed by Hitsugaya and then there was some confusing Aizen related bits before there.
So... This is what I recall happening in the Winter War.
Hinamori showed up. Got hurt. Kira was tending her and Matsumoto while Aizen was fighting the others. Kurosaki showed up. A chapter or three later "Hinamori" was getting up and attacked Kira and Hisagi(99% sure). And then we are informed after "Aizen" is stabbed that that was Hinamori and the "Hinamori" on the ground was Aizen. When in the 9 levels of hell did this switch occur? And what about Hinamori's mental state afterwards? Unohana must've pulled off some great psychology stuff for Hinamori to be fit for duty.
Kubo... If I didn't want to see how it'd all end I would leave. And give me more Kira while you're at it.
