Konohamaru pulling off what he pulled off is damned gold xD. Plus, that's something right out of Naruto's playbook, so I'm sure Naruto showed him everything we saw him do here today. Wow...even shit talked a little about his genetic blessings. He'll make a fine ninja if they don't kill him now.

About Naruto still needing to use clones for the rasengan, I don't think he's even tried to master it with one hand. And something tells me he doesn't need to. Kagebunshin for him is almost more like a power than a technique.
