To me it seemed this episode went by incredibly fast. When the ending song came on I looked at the progress bar and thought no way that could be twenty minutes already.

The only minor complaint I had with the episode is when the leaf with the sunglasses was fighting Kakuzu. A few minutes ago Kakuzu's hands were flying all over the place, now all of sudden this dude with glasses is easily blocking and dodging his attacks.

its probably going to be a sad one next week too if they show him telling Kurenai.
