When Naruto awoke, Hinata thanked him for helping her and returned his scarf to him, but he let her keep it.
He was unaware that the girl's growing affections for him began from that moment onwards.
Naruto's time at the Falls of Truth revealed that a part of him hated the villagers for ostracising him, only to admire him after he saved them during Pain's Assault.
