ok i have a throey which may suck but here goes. what if the vaizards are just using azien i mean shinji knew what azein was going to do years before it happened so why didn't he stop azien i think hes just using azien to start he own plan that is greater than azien's and also what if ichgo's father became a vaizard and thats why he left what do u guys think?

ohh very good prediction man....may be tru

No the reason Ichigo's father left was cuz his powers where gone

The theory that vizards wanna do something may be true though
cuz they don't have any connection wit this war

ok maybe i may be wrong on ichigos father but not about the vaizards and azien may be just a pawn to shinji since he was his former capt and its obvious that shinji knows what azuien is thinking

he knew every thing yes but not about aizen not being with him when he was his Lt....oops spoilers

np in like 7 more episodes it will be revieled

ohh yeah haha ur right

dude he told ichigo about what he knew which was about the orb thingy and when he defected

ohh brago made another good point

the gigay thing that restores powers urhrha made it

but when he defeated grand fisher, grand fisher was in adjuhas form

a what form? also maybe he defected cuz he was in a mission in the human world and saw a beautiful women and that women was being targeted by hollow and he saved her and they had an affair and then he deffected and as more longer time in giga he got powerless
