They are both sad because Hanabi has been kidnapped.Its not rejection.Does that change your opinion?
But that's your opinion, not a fact given to us. This scene could have taken place before Hanabi was even taken and Salsalover64 point of it being a rejection can be true. There's also the possibility that they met at Neji's grave and we're talking about him while walking back. The pic only makes NaruHina a possibility, it doesn't confirms anything until we're actually told they are together, given a romantic scene pic of them or until we watch it.
They said Naruto, Sakura, Sai, Shikamaru, and Hinata goes after Hanabi; Sasuke is in the movie so he's probably not in Konoha. That doesn't seems like SasSaku is happening or if it does not to the end. So Naruto could end up with Sakura, Hinata, or neither of them. He can easily end up like Jiraiya who didn't get the girl he wanted (Tsunade) and lives as a prevy hermit. Kishi already showed us how alike Naruto is to Jiraiya by showing how kid Jiraiya acted like kid Naruto, both went after their best friend who left the village and fell to bring them back, Naruto showed some prevyness by having the sexy jutsu which he taught Konohamaru by looking at adult rated magazines and going into the women bathroom in part 1.
