Has anyone ever thought that by Yhwach being able to see every possible future that he unknowingly saw the use of Aizen's shikai in a particular future, thus putting himself under the effects of Aizen's illisons? from that point on? I mean, that is completely possible and because he could have seen it, he'd have no way to undo it either. Yhwach could have possibly screwed himself by simply looking at Aizen to begin with. I've been thinking about this since Yhwach first visited Aizen.

I know from that point on Yhwach could still see every future from that point on, but what if that meant he couldn't tell reality from illusion concerning Aizen, or anything Aizen's affects?
