The only thing i find interesting about this arc is that they gave some semblance of background to Asuma. It was nice seeing the 3rd again even if only for a few seconds. I found it interesting as well they showed him interacting with Asuma. First episode seemed really rushed, while the second dragged out to milk time for next weeks chat fest.

I feel they will waste a majority of the episode having Asuma and Kazuma talk to each other; how kazuma survived, how he met these people he associates with now, and how Asuma couldn't bring himself to actually kill him the first time around but will now not hold back because he wants to protect everyone in Konoha from Kazuma's destruction. Like father, like son in other words.

Hopefully I'm wrong. if its not this episode, it will probably be the one after it.
