@Grimmjow2 I took Aizen's lack of Bankai and him being sealed as "he'll be back!"

Seriously, Kubo might as well have had Aizen scream "I'll be back!!!!!!!!" But not to worry. He won't be back any time soon. By the time he comes back, everybody would have forgotten all about him and totally not expecting him to show-up but wham! Another curve ball will hit us and we'll be like "Wah!"
