It was hard to watch Sirius like that, Remus wanted to wrap his arms around his friend and comfort him, simply pushing his own hurt away to take away the hurt Sirius was obviously feeling. Instead he moved to sit next to the other boy but resisted the urge to touch.
"I don't hate you." Remus started not sure what to say, he didn't want to see his best friend hurt but he also wanted to make sure Sirius knew that he hurt not just Severus but also his trust.
"Sirius, I really do not hate you but you hurt my feelings, I was almost a murderer." He shuddered as he spoke, he had been thinking about that for a whole week but saying it out loud made it even more real. "I could have killed Severus."
He looked at his hands for a few moments not sure what to say or do next, he turned to face Sirius. "Please, Siri, tell me how I can forget that I almost killed someone I have classes with almost daily?"
