Hot off the presses from LoveDrop, a doujinshi group in Japan, this morning. The way Ichigo would REALLY hold a woman's hand:
Kishimoto-sensei and Kubo-sensei discuss the recent drama over beer.

IchiOri fans were overheard to say that even if this handholding scene in episode 167 was filler, it was STILL indicative of a future relationship between Ichigo and Orihime because in Asian cultures "the first time" holding hands is a very intimate thing and only designated for couples to be.
Studio Pierrot assigned that first time to Ishida and Orihime--the moment, too, was pure filler and never occurred in the manga:
Ishida's hand sure looks like a warped baby mitt there.
Carry on. I'm still cleaning for Passover and maybe when the kitchen's turned over, I can read chapter -105. SPOILERS LOOK THRILLING.
