It also said in the episode preview naruto will learn on the go. I kinda wonder how Orochimaru will go about getting Tsunade to heal him(assuming she does).

As far as the next episode, i think itll largely befocused on orochimaru and Tsunade. Looks like the next episode will be heated and the episode after the conclusion.

EDIT: Misread the subtitles. I guess Naruto wants him to teach it to him on the road. He never said he would. When naruto says "You are too reckless to teach the third stage while walking." It implys that he does. It looks like that also.
