Yamato, Naruto and others in “Unfinished Business”

Yamato

Mutual respect and trust are essential elements of teamwork. Wasn't it Kakashi that taught you that? You are part of the team led by the great Kakashi. Lose the attitude.

Naruto

He's not a member of Team Kakashi! The fourth member of Team Kakashi is and always will be Sasuke Uchiha! This guy, he's just a fill in for Sasuke. That's all he is. He'll never be a real member of the team!

Sai

Well I'm glad that's how you feel. Sasuke is a traitor. He betrayed the Leaf and joined Orochimaru. Yes you're right. I'm not him at all. I'm not a traitorous cockroach. I can't fill in for someone like that.

Naruto

I've had it with you Sai. [Sakura stops him from saying anything]

Sakura

Remember what's important Naruto. It's teamwork. Calm down. Sai, Naruto was out of line, but it's just because he doesn't know you well enough yet. I'm sorry. I hope you can find it in your heart to forgive him.

Naruto

But Sakura...

Yamato

Glad we have one levelheaded person on the team.

Sai

Oh don't worry. He doesn't bother me in the least.

Sakura

Good. That's a relief. [sends Sai flying with a punch] I don't care one bit if you forgive me.
