Back when Hinamori and Hitsugaya talked through the monitor thingie. Hinamori said that Aizen could be doing what he is doing because he was being forced, upon which yamamoto immediatly threw a hand infront of her face, after which she collapsed, and then there was no further mention of this.
What do you think about this? when i heard it i immediatly thought that yamamoto must have forced Aizen to create ouken and all that, so that Yamamoto could kill the "king" himself.. but that seems unlikely..
What do YOU think?
