One of the best episodes I've seen within this arc. It really brought me back to the reasons why I still watch the anime, even with the filler (which wasn't too bad in this episode). I feel like watching it again; it's THAT awesome.
Why do people still find the Buggy filler annoying? This time it was done pretty well. (More importantly, no Hancock filler.)
And the anime seems to have a new habit of slightly lampshading those "boom" moments in the manga. Well, whatever works.
Edit: I don't know about the next episode, though. It might not be as good as this one. Here's to hoping that I'm wrong…
