There's a little, purposeful exhale --Kiden herself is not vexing Charles (in spite of her attitude) but he feels slightly frustrated by the situation as a whole. There's a lack of resources for mutants or xenians, and life here is, on the whole, much harder for them.

"Nothing. I'm sorry to have disturbed you. I wanted to make sure you were all right and --" he makes a little gesture with one hand. "You're fine." In a certain sense of the word. "So I'll be off."

He steps back a couple of paces and gives a little nod, saying, "I'll no doubt see you around." So unless Kiden stops him, he'll turn to go.
