Truly, Arthur's reaction perhaps isn't as extreme as Mark's, but it's certainly coming from the same school of emotion. His eyes widen, the tips of his ears go scarlet, and his only movement is the way his eyes dart between the visibly ravaged Sandazhard and the woman he doesn't know, though he's fairly certain is a fellow Knight.

Something about her gaze on him makes him want to straighten his shoulders, maybe tuck in his stomach, touch his hair, his jaw. But his shock at the situation stills his nervous gestures.

"Er, I'm very sorry," Arthur very nearly stammers, wishing perhaps that he'd just knocked and gone away. "I didn't mean to interrupt... any sort of, er... tryst."

Immediately he winces, wishing he could take that word back.

"That is," he adds, trying and failing to salvage the situation. "I can — go."
