Klaus/Sirius
It had been days since he'd been back, nearly a week - but Sirius was still feeling a little off balance. But a party was a temptation too great for even a internally conflicted Sirius to resist, so he'd gone, though he'd done without a lot of the pageantry, it felt a little too familiar to things he'd like to forget. But he was there, and he'd helped transfigure a few outfits for people who had requested it, but otherwise was kind of quietly watching most of the goings on.
So when Klaus found him and offered him a drink, Sirius didn't mind the interruption to his nothing. "Cheers," He lifted the glass in thanks after he'd accepted it. And nodded with a quiet huff. "Depends on the reason for the party." He admitted shaking his head.
"I think my parents could have been all too happy at a party like this," Though only if everyone submitted to the theme, and only if things were kept rather sedate and proper. "But it was never really my scene." He told him shrugging, "The robes weren't too different from all this if you were going to a formal affair though." He told him, maybe not quite so flashy in some cases, and as things got more modern the styles changed more and more, Sirius had no doubt that in Jamie's time things would be even further removed from all of this. "What about you, you're looking quite at home in all of this."
