Naruto and Gaara in “Unfinished Business”

Naruto

It's almost unbearable, isn't it? The feeling of being all alone. I know that feeling, I've been there, in that dark and lonely place. But now there are others, other people who mean a lot to me. I care more about them than I do myself, and I won't let anyone hurt them. That's why I won't ever give up. I will stop you, even if I have to kill you.

Gaara

But why? Why would you do this for anyone but yourself?

Naruto

Because they saved me from myself. They rescued me from my loneliness. They were the first to accept me for who I am. They're my friends.
