"Had to dance," Marcus muttered. "S'part of how shite works. There's a party. You dance. Isolde likes it." He'd been taught to dance when he was a kid, all awkward and towering over the girls his own age, just because it was expected as a pureblood that he'd be able to do it. "S'got a beat, though. Tempo. S'like music when you're doing this." That give and take, ebb and flow. That's what he liked about the peace of spinning.
His foot didn't stutter as he shot a look at Millicent. "Why'd you put two beds on top of each other?" It sounded uncomfortable, and Marcus sure as hell couldn't think why anyone'd want to sleep in the same room as someone else when it wasn't required at Hogwarts.
