"Very," Marcus answered honestly, returning Roger's grin with a smile of his own. The artist had made an interesting face at seeing the Mark that he'd wanted to cover, muttering something about 'shoddy work' before beginning. The new tattoo went from his wrist almost all the way up to his elbow, and there was no trace that there had been anything there before it, which was more than he'd thought to hope for. "I know," he said, even as he attempted to peek under the wrapping that covered the length of his forearm. "She said to leave it on for twelve hours." He'd paid close attention as the artist had explained, and the sheet of instructions (which was far flimsier than parchment and had felt strange when he'd taken it) was safely in his pocket.
Feeling Roger's eyes on him, Marcus glanced over, and at the question, he nodded slightly before saying simply, "Bryony drew it." It occurred to him after he'd spoken that there was the possibility that Roger wouldn't know who Bryony was - a strange concept, after having grown up around people who always knew who everyone was and what their connections to one another were. Rather than get into all the complicated details of his relationship with her, since it would serve to put him in a strange mood and he was perfectly happy to continue his pleasant time with Roger, he limited his offered explanation to, "She's my best friend."
