One theory could be, simply being a captain they had access to confidential information. However, I was wondering if they went to King's realm in person? The discussion between Urahara and Aizen at the end of HM arc was intriguing:
Chapter 421 Panel 21
Chapter 421 Panel 22
Especially, in the Panel 22 Urahara said "I see, so you've seen it". I was under the impression that every captain might have seen Soul King. The way Urahara said it, implies otherwise. I mean, if every captain has seen SK, Urahra would not be saying such a thing.
First agenda of discussion, have these two been to Soul King Palace?
If they did, what could be the reason?
