This chapter was rather interesting to me, but I was rather disappointed when Kakashi didn't further explain on the other non elemental jutsus. I'd just like to remind you guys that the elemental jutsus were introduced way back, as in the characters, when using elemental jutsus, will shout out it's type. For eg. Katon (fire), Suiton (water), Douton (earth), etc. However, the mixing of the types is totally new and yet to be explained fully.

I'd like to think of the bloodline limits as still due to the genes passed down from generations, and not some sort of weird ability to mix affinities. But like I always say, it's not worth it to over analyse some times unless the mistakes or ambiguity is staring at you right in the face.

On Asuma, I hope he doesn't leave die so soon. And by the way, who's Konohamaru's father......?
