Marcus couldn't help chuckling at her reaction - it was pretty much exactly what he would have expected. He was well aware of Bryony's love for all things Quidditch, had probably helped to feed it over the years with his constant ramblings about it. "I certainly wouldn't let anyone else take you to your first match," he answered with a grin, pleased by her excitement.
Letting her turn his arm this way and that, examining the tattoo from every angle, Marcus smiled at her words, because really, amazing was the perfect description. He never would have thought to cover the Mark with more ink on his own, and certainly wouldn't have been able to think of anything as fitting as the drawing Bryony had done. But now that the new image was there, he felt freer than he had since the day he'd been released from Azkaban. Sure, there would still be people heard his name and associated it only with 'convicted Death Eater', but at least he was no longer carrying the symbol of that title with him everywhere he went. Bryony's fingers weren't intrusive or awkward, and Marcus didn't tense under her touch, the way he might have with anyone else - she was too familiar and comforting of a presence for him to feel strange about the gesture.
He almost laughed again at her comment, because that was such a typical Bryony response - he could tell she recognized the work as her own, but didn't want to admit to it, even though they were both well aware of the fact. Her modesty still managed astounded him sometimes. "You did," he said quietly, because he wouldn't hide that truth from her, or anyone else, should it ever come up. "Draw it, that is." Marcus shrugged, not meaning to downplay the importance of his choice, but because he couldn't have imagined choosing anything else. "Sorry I didn't ask your permission first."
