Mark's head snaps back at Arthur's words, and he stares at him uncomprehending for a second, raising one hand to mirror the man's motions. When it sinks in what he's getting at, his embarrassment only seems to ramp up a notch and he mutters "Oh geez" pawing at his chin, and ducking back into the room, heading for a bureau so that he can check things out in the mirror. He not only scrubs off the lip gloss, but rakes his fingers through his hair, and then seems to notice his collar, and awkwardly fumbles to refasten it, trying to avoid Arthur's gaze in the reflection.

"Of course, uh... course you can. Just give me a ..." He turns around when he's apparently completed his cursory touch-up and glances around the room for anything incriminating, but the only sign of anything out of place is the red chair scraped away from its spot by the wall. He wipes a palm across his mouth before focusing back on Arthur, and then seeming to realize something else that fills him with dread. "I'm sorry. This isn't how I wanted to--" He takes a deep breath and looks down, licking his lips, before forcing a smile and meeting his gaze, his entire posture seeming to tighten up like a soldier. "... It's an honor, your Highness."
