Haha - you mean like Amon wasn't Zaizen's boy any longer? XD

...Don't worry. When Ulquiorra comes back, it won't be as Aizen's lapdog...(I'm wondering just how much of that he was from the beginning, anyway, with his hiding his 2nd release from his boss)...because the fact of the matter is that Aizen has nothing to offer him now.

It's Orihime who he'll be loyal to. When he comes back more powerful than he was before, it's her he'd have to thank for that. :)
