User blog comment:Darknesslover5000/What did Aizen mean when he said to Ichigo "Eating you...is something that can be done after all is finished."?/@comment-1883774-20100606012157

Aizen's eyes have nothing to do with him being hollow. (I' am not saying he is.) Just because Ichigo's eyes changed and look black does not mean that everybody who turns into a hollow will have black eyes. Aizen's eyes probably changed for another reason.

I am not saying he is or is not a hollow.
