Chapter Text
Sirius was having breakfast with his friends. James was beside him Talking about the latest Quidditch match with Peter. Today was a full moon, there were only two left till’ the end of the year and they were going to go with Remus, as always. Remus was noticeably more tired than usual, he had the same distant eyes as every moon. Sirius hated seeing him like that. He wished he could keep him safe forever.
At that moment, the owls came flying with the post, a red envelope falling directly on Sirius’ plate. He didn’t have much time to react before the voice of his mother could rise.
“HOW DARE YOU COME CLOSE TO OUR DEAR REGULUS” his mother’s voice seemed to fill the room, everyone’s heads turned “YOU ARE CORRUPTING HIM, WE FORBID YOU FROM EVER TALKING TO HIM, YOU MADE A CHOICE WHEN YOU ABANDONED US, YOU LEFT SO DON’T TRY ANYTHING TO TAKE REG-” he didn’t know when he had started running, but he was, away from the pitying eyes and mocking faces. Away from Regulus and his friends.
He had started talking to Regulus after he ran away. He had told him that he forgave him and that he understood why he left. They even had made plans to help Regulus run away that summer. He didn't know how his mother had found out about that.
He found himself on a dark corner, his head hurting and his heart beating a hundred miles an hour. His mind started to cloud something that had started to happen back at home, when things would go bad with their parents.

He woke up some time later, when the sun was already missing from the sky, the werewolf would come anytime now. His head was burning. He barely remembered where he was. He looked around him and he didn't know when he had gotten there. Suddenly he remembered something. Snape asking about the moon?. Fuck. Remus.
He started running as fast as his feet would let him.He didn't know how but he knew that he had told Snape how to get to Remus.
“Sirius what happened? We thought we would have to leave without you” said James while walking towards him. Right after him entering their dorm.
“I told him”
“What?” Peter had gotten up from his place in James’ bed and was looking at him worriedly.
“I told Snape how to get past the Whomping Willow”
He saw exactly the moment the color drained from both of his friends’ faces.
“Peter go get Poppy” James was already running out of the door, with Peter close behind. Sirius started running as well, a fog over his afternoon memories. He didn’t have time for that, Remus was in danger, he was supposed to keep him safe, and now he had put him in danger.
When he reached the tree, James had already gotten in. He could hear some distant noises. He was about to enter when he saw James carrying an injured Snape out of the passage. He had blood all over his clothes.
“Oh god, is he okay? How can I help?”
“Go away” James was dragging Severus to the castle. Sirius tried getting close to them. He had to help. He couldn’t just stand there.
“What? No, I have to…”
“You don’t need to do anything, you fucked up hard enough”
“No wait, let me explain” James was getting away, he tried to move but his feet wouldn't move. He couldn’t breathe.
What had happened? Why did he tell Snape? How could he do this to Remus?
What had he done?.
