Now people just let one thing clear - Urahara when first showed up there in FKT, stated Aizen had fused with the Hogyoku, then Aizen clarifies with Urahara that he he finally subdued the thing, well Lia I dont say I do not agrees with you but which part do you think that the orb has its will that it is wanting to have a body of its own... (becareful lol don't turn this into just another crack theories though)
