Also @Nick: It was more like Ichigo's not-even-10-year-old son absorbing what remained of Yhwach because he's part Quincy. The Soul King also had to be replaced otherwise Soul Society would have crumbled to pieces. Aizen was also gravely wounded after the battle, so I'm sure getting him back to his cell wouldn't have been terribly difficult for certain people. What we really need is a databook, but I was completely satisfied with the ending regardless.
