I must say, I was pleasantly surprised that this was not filler, or at least it didn't feel like it. I'd be willing to bet very little to none of this episode is filler.

Really looking forward to next episode. I always wanted more back story for Kisame. Though it would seem to come at his expense given past examples. I'm surprised there wasn't a bit of a joke about Guy not remember Kisame, again. It seemed to piss him off a hell of a lot last time.
