Sirius dragged his trunk carefully off the train, saying his goodbyes to James, Remus and that Pettigrew kid, promising to write. He didn't see his parents
Andromeda walked past him with Narcissa, hugging him, telling him to be careful and she'll see him soon.
The crowds were thinning and finally he saw the dark head of his mother. Sirius walking slowly over to her, dragging his feet because he knew that would annoy her. He really did enjoy feeling defiant far too much.
Eventually he reached her. She grabbed his arm, nails digging into his flesh. Not saying anything she apparated home with him.
When they reached Grimmauld she shoved him up the steps roughly, not caring if Sirius stumbled. All too soon they were in the gloomy house and Kreacher greeted his mother and took his trunk with a glare.
Walburga pushed Sirius away from her and slapped him across the face.
"Get out of my sight you ungrateful brat," she hissed, "You'll be dealt with when your father gets home" and Sirius fled upstairs fingering the tender spot on his cheek.
He looked across at his brother's room, noticing the door was opened and Regulus was peering around it.
"Hey, Reg" Sirius said with a smile only to turn into a frown when the door was slammed without a comment.
Sirius made his way into his room and flung himself on his bed. He stayed like that until late in the evening. No one had talked to him or called him down and he was feeling very nervous. Finally he couldn't take it anymore and he wrenched open the door and listened carefully. Silence, but then again he could never hear anything from up here.
Sirius walked cautiously down the stairs taking care not to make any of them creak. He got to the living room and he heard the hushed voices of his parents. Sirius opened the door silently and his parents turned to face him.
"Sirius," his father said, "We were just about to summon you."
Sirius inaudibly gulped but kept his face carefully blank.
"We have decided," continued Orion Black, "that although you have brought shame to us by sorting into Gryffindor we will forgive you if you befriend the right people."
"Basically, get rid of the half blood and bloodtraitor darling Cissa told us you were hanging around."
"But they're my friends," gasped Sirius
Orion sent a stinging hex at his son snapping, "Don't talk to your mother like that,"
"I won't" said Sirius stubbornly, ignoring the biting pain he felt.
Walburga made as if to slap him again but Orion stopped her.
"Then go to your room and do not come out until you change your mind."
