This is coming from a filler episode...Besides i think Aizen only said sorry to Hinamori just to more or less to add insult to injury.

I had never think that Aizen isn't the mastermind because the real masterminds ever the most unspicous poeple are so it was clear that gin it couldn't be.
And Hinamori were/is in love with aizen but Aizen only use her.

No way. Ichimaru's never seemed as much of a bad guy as Aizen. I think that Ichimaru is under Aizen's control. Hinamori was a bit too brainwashed by Aizen to see the truth about him. Aizen may have his own problems, but he's definitively the main bad guy (so far).

Hmm..even though Gin scares the heck out of me with his smile, I don't think he could have actually been the one behind all of this. Like Pyro said before, he DID help Rangiku. I think in episode 62, he looks kinda sad when he leaves Rangiku, so he can't be all that bad. Hinamori's is madly in love with Aizen, which is why she just can't see him as being bad. She really is messed up, but I do feel bad for her also. Aizen is evil. That's all there is to it. He deceived everyone in Soul Society. Maybe they'll reveal just how evil he can be in the future.

Personally I think this is just wishful thinking on people's parts both fictional and real. A lot of people are fans of Aizen or hate Gin so that want to down play their level of involvement. Characters like Hinamori who were so fully deceived by Aizen and worshiped Aizen will have the hardest times accepting his betrayal as genuine.

Well, I haven't reach that part yet ( being still in episode 89 ) but I think thats a bit possible, seeing how bleach always go on with so much and so many surprises.

But honestly and personally, I don't think that that is possible. I mean just look at Aizen when he was about to be taken by the Huecos thingy. Fine, HE DOES LOOKS COOL after he changes his appearance a bit, but being honest, he does looks cool enough to tell us that he is the one who is in charge of the rebellion and the master mind. I mean, before then, Aizen was the captain and Ichimaru was his lieutenant. Its is nuts to think that a lieutenant ( though later one become a captain ) is the master mind while his captain is his right hand.

Then too, you must consider the fact that Hinamori really admires, if not love, Aizen. ( How could you like such a jerk, but then, he is a charming prince before we know that he is a traitor, isn't he ) When someone is in such condition, how could you expect her to say that Aizen is wrong and traitor?

Wow.. *blinks*

Never actually thought about it.. since at first I actually thought that Gin 'killed' Aizen, and was so surprised when it turned out that it was Aizen's masterplan all along.

It is possible, but it's more possible for me for Gin to somehow overthrow Aizen.. someday.

Honestly if I ever thought that Aizen is the one being manipulated and not the manipulator, I would believe that Urahara is the mastermind. He seems to know then most people and keep talking in slight riddles.But the chances of Urahara being the mastermind is very slim though.I don't think that Gin could be the mastermind because of his scene with Rangiku ,the part where he left for Hueco Mondo and said "I wish you could hold on a little longer..." Watching that scene ,I actually had a theory that he might actually be undercover or something ,but again the chances is very slim.

I suspect that Gin could very well be acting as an infiltrate.I mean, who's better than the guy with almost no friends and impossible to read? And with some recent cases happening in other manga/books/whatever, I think it's a possibility.

I like that if Gin was only infiltrating. but with his status, i think Gin has no clear path in front of him. he's just riding along with Aizen cause maybe that's more fun for him and suits he's grin all the time. you think maybe everything is still under Aizen's illusion since i really can't understand why he planned to do all that. plotting to eliminate the King of Soul Society may mean Aizen has a deep grudge. but who is Aizen actually?

he's capable of everything but how and why he came that way.
i think Aizen is of royal family which something bad happened that he didn't like and never accepted.
