Naruto is captured by the Akatsuki, and what's worse is that Sasuke was the one that formally caught him. Yet even that isn't the biggest problem. Naruto is going mad. When He had met Orochimaru, Orochimaru had put a curse on him. THe more the fox's powers leak, the faster Naruto's mind shatters.
Sasuke is face with a big diliema. Yes, he had captured Naruto, but he never intends to keep Naruto in the forsaken place. Yet when Sasuke heard Naruto when he had an...episode, Sasuke knew that he needs help. From a friend. But what if Gaara takes that spot away from him?
(Read this story. It's alot better than how I described it. I suck at this XD)
