Actually guys all this makes perfect sense when you calm down and think about it. I would assume that Aizen did his little switcheroo right as Shinji used his Shikai. After that it was all a flash with Hitsuguya. Ichigo can't even keep up with Aizen, so Aizen probably switched with Hinamori in that instant. I only assume this because Aizen is a dick and Hinamori did not have a stab wound from Kyouraku. Of course though, it still all sucks. Ultimate Genjutsu ftw I guess. Need a freaking Uchiha in this manga now. I really hope Old Man Yama gets off his high horse now that all his fighters are down and starts setting stuff on fire. I mean, being the oldest captain there he must have a trick or two up his sleeve, but then again, Kubo always manages to disappoint me.
BTW Kensei probably lost... no he did lose. Probably eating dirt with all the other captains. Same for Byakuya and Zaraki. Probably face down right next to the FORGOTTEN GRIMMJAW!!!
