I have no problem with the attack names since they're all made up anyhow. Really, call it anything you want. Won't make any difference.

But about the ep, I'm wondering why Byakuya hasn't defeated his zampakutou yet. If Ichigo could stand up to it, I'm sure Byakuya would know more about its fighting style and be able to win easily. There's also the question of what this signifies for Rukia. And there is the question as to how the fight between Byakuya and his zampakutou ended. Why did it end? Why are they both still alive? I think Byakuya let his zampakutou live. To what end, I don't know.

And is it just me, but do the live incarnations of the zampakutou's overall seem to be more powerful than when their Shinigami is weilding them? Especially with Renji, it just looks like two different levels all together.
