Sirius could be as contrary as he liked as often as he liked no matter the situation, particularly when it came to his brother who had joined with a murderous zealot just to spite him. He wasn't feeling all that forgiving of that particular confession just yet, but he wasn't in a hurry to run out of there just yet either so that was something.
"I'm sorry I didn't hate my life the way you wanted me to." He said with a sigh, because that's all he could say. "But getting to school, getting sorted into a house I never expected to wind up in, I realized for the first time that I didn't have to be miserable just because our parents said we should. Merlin forbid I try and tell you about it when I got back, who else was going to tell but you?" Because they were great friends, even Peter for a time, and he loved it, he loved being something more than just a son of the House of Black, he could be a Marauder. "Has it ever occurred to you that you could have done the same? You could have started something new there too?" Because Sirius wanted more from his life than all of that, than tradition and the hateful life that his family would have resigned him to if they'd had their way.
Sirius rolled his eyes, "Listen to yourself, we're not students anymore. We don't have to be that. I am not that anymore. This place doesn't even know what Gryffindor and Slytherin are except for a few prats who can't leave the past where it belongs." He wanted to scream, even here in another world, these things were haunting him. "If you want to live here, and make a life fine, marry your half-witch and be more than a fucking Slytherin idiot for once in your life. And for whatever time I'm here I'm going to be anything but a fucking Gryffindor asshole, okay?"
