Unquestionable theory Number 1

The mystery that shrouds Isshin and his identity.

I've been researching an awful lot of shit. Some things alot less subtle than others but in my research I came across something. Somethign unquestionable and something that makes the most fucking sense I've ever heard in my God damned life. . . . Okay I exxagerated but seriously this makes sense. Before I tell you my theory I want to point out the Facts.

When you look at this Gif just look at Aizens Hilt guard. Ignore everything else, Just look at its shape and its design.



Now look at Isshins Zan hilt. This is just a small piece of evidence towards my theory but add two and One together and you see so far. . . You have three.

Remember when Aizen Defected from Soul society? Ask yourself one question. . . Did you see Isshin there when he did so? So how is it. . . . That why is it that when Isshin finally made his grand apperance in the Arrancar arc as a shinigami, he immidiately pointed his finger at Aizen assuming that he was behind the Arrancars developement?

There is no other possible way of him knowing about Aizens defection if you were not there to witness it firsthand or before hand and he couldn't have been told if The vizard leader (Shinji) who has been a Captain before the previous generation, didn't even know about him and Urahara admitted to finally meeting him again after "All these years".

Yes by now you are asking yourself; Where am I going with this? But with this last piece of evidense you should be able to figure it out.

Spoiler:

Now then, Ichigo is sixteen right? and if he knew about him since he was born he had to have had a reason right? I doubt Aizen is scouting some random baby because he is a pedophile and accidentally figured out that he has the finest "raw materials" Aizen needs. And Aizen immediately realized Isshin and Vice versa as soon as Isshin came on the scene to cut Aizen off. So how is it that Aizen knows Isshin while No one else but Urahara does? And how is it that Isshin; Out of all the other Captains; Put up more of a fight for Aizen then all of the Vizards and Captains combined. Granted near the end he did say he was reaching his limit but still.

Any questions?
