Aye. The story hardly went anywhere. And moreover, I don't really see even the whole point of the bulk of this episode. They used all too much time for a few bonehead bus hijackers. I think they could have cut half of this episode away without losing anything at all.
And there wasn't even any fanservice...
Well, at least Nina is back. Lets hope she will kick ass. At least she should have attitude for that if she regains her spirit.
