Oh, I totally get what you're saying. I don't think he absorbed ichigo's inner hollow, for the very reason that you said. I just think that the small portion of hollow reiatsu required for a fullbring, when gathered en masse, would lead to some adverse effects.
Eh, next chapter is basically gonna be a fight with a bunch of explanation of who Ginjou is from the Captains... someone's gonna be like "Yeah, he did a damn good job until something corrupted him...." and someone else will be like "Must have been Aizen and his hollowification" and then Rangiku is gonna be like "Look at my boo.....umm, yeah, you're right Toushirou-kun!" and then Toushirou is gonna blush and be all like "Uhh, where did Kenpachi go?" and Kenpachi is gonna be all like "You can't beat me!!!".....
yeah, after having read what I just wrote... it's definitely not gonna happen like that. But more than likely, it will still be a big fight scene (probably just one or two slashes of their swords), a little bit of talking, a big blank page (or black page), and the end. Oh, i forgot the page that is pretty much their feet in little panels and the title of the chapter running really hugely down the middle. Sounds like the stereotypical Bleach chapter to me..... But i still love the series. cheers
