The seventeenth time I shared a bed with Sirius Black was the night after the incident with Severus. Moony was still in the hospital wing and Wormtail was asleep in his own bed on the other side of the room when Sirius came across and pulled my curtains open. I ignored him, anger still burning in me at what he had almost done to Moony.
'Prongs...'he started. I turned my back. I could hear him breathing next to me but not saying a word. He reached out, laying a hand on my shoulder. I turned and glared at him.
'How can you still call me that after what you did to Moony? You know what would have happened if Snape had been hurt? Moony would have been expelled! He could have been arrested! And it would have been all your fault. How could you do that to him? Not to mention Snape. Would you really want him bitten? Are you that heartless? You're more of a Black than I thought you were, Sirius' I tried not to yell, not wanting Wormtail to wake up. Guilt was written clearly on Sirius' face, as well as immeasurable pain. I knew I'd done the unforgivable, calling him a Black, but he deserved it at that moment in time.
'I never thought...'
'That's right. You didn't think.' I hissed at him, grabbing my curtains and slamming them shut, intending to just go to sleep and ignore him.
'Prongs,' he was still outside. I didn't answer. He seemed to take that as permission to keep speaking, 'I went after you, when you went after Snape. I followed. I never thought he'd be stupid enough to go out there on a tip off from me. He knows how much I hate him. I was just going to use it to call him a coward. I never wanted Moony to get hurt. And...he made me angry. He was insulting you, insulting what the Marauders are. He said Lily was just one of your whores and she'd come to her senses soon enough when you left her alone and broken after you were done with her. I tried to curse him but he'd already disarmed me, the creep. I couldn't think of anything else to do. I just wanted to prove he was wrong, to make him look stupid. He had no right to say those things about you and Lily. I'm sorry. I...don't make me lose my best friend over this, please....' I could hear him sobbing on the floor beside my bed. I sighed and opened my curtains.
'That was the stupidest thing you've ever done, Padfoot.' I murmured. He nodded, unable to speak through the tears.
'Promise me you'll never do anything like that again,' He nodded, 'Say it,' I hissed. He took a deep breath and fixed his eyes on me.
'I promise' he whispered. Something between us seemed to suddenly thaw during that moment and I grabbed him, wrapping my arms around him as he cried guilty tears. I pulled him gently into my bed and lay down next to him.
'He's going to be alright you know,' I said after a while. He looked at me, confused, 'Snape,' I clarified, 'He wasn't hurt. He knows about Moony now though, so we'll have to be extra careful. I think we're going to have to leave him alone from now on, whatever he says or does. Agreed?'
Sirius just nodded, grateful to have been accepted back, at least by one of his friends.
