Bryony's laugh made Marcus grin - it was a sound he didn't hear nearly often enough, and he was always happy when she was happy. He let her pull away, following at a slightly slower pace, content to let her lead but close enough that he would be nearby in the event that anything unfortunate happened.
He barely glanced around once he cleared the roof - things were mostly the same as they'd always been, the trees a little taller than the last time he'd seen them, but nothing jarringly different. Seeing Bryony take off, he chuckled again, making sure to keep her in sight as he followed. Though they both knew he was more than capable of overtaking her, Marcus didn't feel the need to - as in most things, she was the only exception to his usual competitive streak, and even as children he had allowed her to best him in these sorts of things.
"Do you have a destination in mind, or will I find out where we're going when we get there?" he called out, still teasing, though his voice was pitched a little louder to carry, though by no means near his typical bellow on the Quidditch pitch.
