I would also like to note that Aizen seems to have lost a bit of his composure in the last pages of the latest chapter. He seemed to show a bit of anger, calling Shisuei a bastard (quite unusual for the normally confident and calm Aizen, don't you think?). He also lost a bit more composure when thinking "shit...", showing a bit of surprise, and possibly just the smallest bit of panic or something.
