At the very least, though, he's finally been able to relieve that burden of not knowing his Zanpakuto's name. He was kinda sad about that after his fight with Ichigo, but it hasn't really been mentioned since. Now that I think about it, that may be contributing to his seriousness in this week's chapter: he's learned exactly was his sword was going through (Ichigo could literally hear it screaming during their fight) and has grown a bit because of it.
