SPOILER!

Tite Kobo said that in the next arc Aizen will appear again! aizenplz
And many other things...So yes, Aizen is in this moment is jail. It is 100% sure
If you want the side where is the interview tell me.

Gods don't need people to feed them. I mean, Gods higher than Shinigami. Aizen is THE god

I love Aizen. HE is in my top 3 favorite characters

ITS ALL PART OF HIS PLAN!

I doubt that its part of his plan, but he'll have a plan for escaping for sure... maybe he wasn't prepared for Ichigo and Urahara defeating him, but there are the zero guard and the spirit king himself who he would have had to defeat when he wants to be spirit king, so he has to have a plan for the case of failure.

typo locked up for good

Aizen is just to beast to be looked up for good

As much as it looks like he's in jail, I have a strong feeling that it isn't him. Think of Kyokasuigetsu (if I spelt that correctly!) And, if it is, he's not going to be there for long.

I'm actually wondering if he's going to be slightly unvillainized and Ichigo will break him out.

(This is all spawning from the scene where Ichigo told Urahara that he wondered if Aizen himself wished in some small part to lose his powers, which was why the hokyouku finally turned away from him. Then Urahara has this funny look on his face - which manga characters usually do when they know something uber-special that we're not allowed to know about yet. Therefore it makes me think there's some overarching plot even larger. It will either set Aizen up as the supervillain or Ichigo will break him out because it turns out the King is really the evil one, or some random twist like that. That's my very vague theory anyhow.)

ARRRRRRRRRRRRRRRRRRRRRRRGHH Just call it (Bleach Spoiler)....!!
jk, I'm only on ep 230 tho q_q
