YET! He decides to go when Rukia goes missing, again. :/
Yeah, following usual shounen mannerism he should have headed over there immediately. I'm pleased he didn't and instead decided to wait until Yoruichi and Urahara can come up with some answers. But now with Rukia disappearing he obviously doesn't have such a luxury anymore.

The one making a mistake here is Rukia, not Ichigo.
