I agree about the Neji thing, I was PISSED Hinata ended up missing the end of that. Not just because I want him to get recognition, but he pretty much dedicated that fight to her going into it. And seeing that would be the kind of thing that inspires Hinata to get better, which could only be a good thing.
It's also a great example of his bragging. Or maybe not bragging, but doing a victory lap around the arena has to be some kind of display of ego.
