I noticed that Isshin was mysteriously absent for the most part when the shinigami appeared, and for all intensive purposes Rangiku and Toshiro were unconscious when Isshin arrived to confront Aizen. Not trying the spur anything, but is it me or does captain Isshin look a lot younger than he is now at the current time in the story and not just Present Isshin minus the beard? I wonder if somehow his gigai aged him the rate of a normal human, in order to have him blend in more with the normal population? If that's true, then it would explain why no one other than Uraharas company recognized him, plus considering he was a captain, I would assume that he would be able to easily hide his presence among most Shinigami.
