Remus was on his knees looking helplessly up at the two boys. He was so, so sorry for what Sirius was doing to Snape. "Sirius, stop it. I'm serious." He grit his teeth and pulled away from the other Marauder.

He gave Snape one last look, knowing it was better if he didn't say anything. "Come on, let's go to the Common Room." He stomped off, gutted.

They didn't have plans to meet again. It wasn't until he passed Snape in the halls the next day and thrust a piece of parchment into the boys hands. It simply said "Library. After dinner."

He knew that Sirius and James wouldn't look for him there.
