One of the most significant differences between Sasuke and Naruto was that by now, everyone knew of the demon Naruto carried inside of him. They knew of the Kyuubi and its power – its importance. And they feared it, even though they had learned not to fear Naruto.
Only very few people could tell that Sasuke, too, was carrying such a demon.
It didn't have a physical form (though Sasuke could feel its claws just perfectly well at times) and it didn't change his appearance when it broke free (though Sasuke hoped he wasn't always scowling this much). But it was there nevertheless, whispering to him all the time.
It was there when Naruto was having fun and Sasuke wanted nothing more than to just join him, telling him, "Remember who you are! You're an Uchiha!" – it was there when he fought Naruto and knew that he was nearing his limits, hissing "Remember who he is! You can't lose to someone like that!" – it was there when Naruto was looming over him, all panted breaths and hot kisses, screeching "Have you lost your mind?! How can you submit to him?!"
It was just there, a dark, angry presence at the back of his mind. It was breaking him down, yet keeping him upright at the same time – because Uchiha didn't break down. They were better than that. He was better than that.
It was a two-faced thing and Sasuke just didn't know how to fight it, was afraid of losing its power. And sometimes he was convinced that Naruto's was the easier opponent. At least the moron didn't have to fight against himself.
