Sasuke: Come, Naruto! If that's how it is, I'll just have to sever that bond.
Naruto: Sever it just like that, huh? Then why do you bother wearing that headband anymore?
Sasuke: I'll admit it, you're definitely strong. It's because you know the pain that solitude brings, just as I do. It's that very pain that makes you and I stronger Naruto. Which means if I can break that bond, I'll be able to achieve even greater strength.
