Her hand fell to his face hard. Sirius was far from shocked, he was expecting such a thing from Bellatrix. She had been yelling profanities at him for almost an hour and throwing various things at him. He tried to explain, but she wasn't listening.
"Dissowned?!" she shrieked, throwing a nearby vase at him, "What were you thinking!"
"Bella-"
"How dare you! And to think I just slept in the same bed as you!" she yelled furiously, not letting him get another word in, "how could you! You let your mother and father believe that you weren't coming back! This is what you get then obviously! We're Black's Sirius!"
"I left a note..." he tried.
"Oh a note! Well that makes it all better then doesn't it?!" she hissed, throwing another nearby object which just happened to be another very expensive heirloom, just as the vase was.
"I tried to explain!" he said, dodging the next thing she was throwing, his mother's favourite china.
They had made their way down to the kitchens and the elf had run away fearing for its life. Breakfast was long forgotten by now. She was furious.
"Don't give me that crap!" she snarled viciously, storming past him and heading back up to his room to get her things and leave.
"You couldn't honestly expect me to stay in this hell hole forever, could you?!" he shouted back, following her.
"Doesn't mean you had to get yourself disowned!" she hissed viciously, turning suddenly, a whiskey glass still in her hand which she threw at him. He ducked, missing it by an inch. The glass shattered behind him and he stormed after her.
"I hate this family, you know I do!"
"I hate it too but does that mean I go and do stupid things like that?!"
"Don't give me that shit, Bellatrix. You agree with everything this family stands for."
"Yes I do." She said suddenly, turning again. They were both stood in the hallway this time, "And I always will. He has the right idea that Tom Riddle. He knows what's good for our world."
"YOU ARE INSANE! How can you say that?!" he bellowed, now furious she could say such a thing.
"If you hadn't been sorted into the same house as those stupid boys, you would..." she had her teeth grit furiously, but suddenly her voice quietened a little and she looked away from him, folding her arms, "...You wouldn't have done any of this."
"Bellatrix, please you know the way I have felt about our families values and norms from a young age!"
"No!" she shrieked again, "I DON'T WANT TO HEAR IT! You have no right to do that! You have no right to leave me!"
Sirius said nothing, suddenly understanding what all of her anger was about, watching his cousin turn once more. She walked into his room, grabbing her clothes she had been wearing yesterday. When Sirius walked in to follow her some moments later, she already had the leather type tight leggings which clung to her skin and her black shirt on once more. She grabbed her thigh high boots, pulling them on one after another.
"Bella..." he said quietly, standing at the door.
"Don't bother Sirius." She said, standing and without even looking at him, walking past him to the hallway once more.
"Bellatrix, listen to me..." he started while following her out of the room into the hallway.
Bellatrix turned around once more, stepping back as he moved towards her. She looked at her cousin somewhat calmly, "You'll regret leaving me here. I promise you that." She said, pausing for a moment and before he could even say anything, disapparating without another word.
