What I did like about that scene was the fact that he IS acknowledging Sasuke has changed. And I agree that facing Nagato was very hard on him. I mean, the man killed what was tantemount to his father figure, destroyed his village, practically killed the girl who just admitted she loved him... and then he watches as Nagato kills himself to correct some of the damage. I can very easily see how all that would be very jarring for him.

The reason I think I'm not really feeling the tears this time is that I'm tired of him doing EVERYTHING for Sasuke. Sasuke chose to leave. Sasuke chose to do all the things he did. And yeah, I understand that Naruto sees Sasuke as family... but it's getting to the point where I'm sick and tired of him playing the martyr for Sasuke's sake. He has other people who care about him and who DIDN'T turn their back on him. I'd rather he focus on his OWN goals (i.e. peace and becoming Hokage) than constantly obsessing over someone who very clearly does NOT want to have anything to do with him.
