He did, didn't he , He was there outside? Ichigo was a good teacher of how to act dead/unconcious/sleep (all those are valid options ) I wonder if Ulqui will use that information against Ichigo or bring it up to break his concentration or something like that. He has that eye that records everything, doesn't he...This is just speculation, but could be. He is known for being very cunning and push their buttons.
I have mixed emotions about showing Ichigo Orihime's thoughts hahaha, but I think if Ulqui does, Ichigo is going to feel a bit hurt and embarassed. He was uncouncious and Hime's intentions were questionable at best.
