Aizen almost have to use his bankai at this point, just because Kubo knows that his fanbase will be in an uproar if he gets killed off before it's revealed. I like Tinni's idea of a house of mirrors type ability. If not probably a mind control ability, but that would need some heavy restrictions to it's use, like the person needs low spiritual pressure.

On the Zangetsu, Engetsu, Suigetsu topic. I think it's not unreasonable to draw a relationship between Zangetsu and Engetsu, because of the relationship of their owners, but until there's something more revealed about Aizen's past, there's no proof saying Suigetsu is related to the other two. There's an old theory, that I will say right now is completely crack and has no proof, that somehow Aizen and Isshin were related, which would make Ichigo and Aizen distant cousins or something. If that ends up being true, which I doubt it will, then just ignore this entire last statement. As of now, the only relationship between the three is that they all have the kanji for moon in their names.
