"Shut it," Severus muttered, his arms still firmly around Remus's neck. "You know nothing." Again, hardly kind words. Severus was digging himself the hole for his own funeral, he just didn't realize it.

When Remus's arms did not come up to hold him back, it occurred to Snape that he was acting like a right bloody fool, throwing himself at someone that was more than likely trying to push him away.

He was heartbroken. He was, literally, shattered inside. Severus pulled back, casting around for a place to go, and fled.

This was both fortunate and unfortunate in different circumstances. Three corridors later and Snape bounced right off of Sirius Black's chest, falling to the floor. Black had been minutes from catching them together.
