I'm starting to get excited about this Kaien-Ichigo-reincarnation-theory :D And maybe Rukia trusts Ichigo more because he seems somehow familiar :) who knows? :D

@ Tinni: I agree, maybe Gramps has realized who Ichigo is, but has decided that it's better not to tell him. Maybe Gramps banished Isshin? Maybe Isshin and Gramps have similar relationship as Kisuke and Gramps? (yama asked urahara to help with preparations).

Oh, and about haori. What I think is that they have captain haori with 0 in the back. (as toshiro has 10 and kenpachi has 12 etc.)
