Charles was pretty much skilled in every aspect of his life. Tracking? Great at it. Hunting? Perfect shot. Robbery? Quiet as a mouse. And he experienced these things often, almost on a day-to-day basis. Things that required being social, well... that wasn't exactly his strong suit. He hadn't gotten much practice with talking and social cues. He still tried his best, though, even if it didn't work.
Charles was sat, minding his own business when he you approached him. You had been very kind to him lately, more tha usual. More talkative, more giving. He noticed, of course; he was very observant. But he hadn't had a clue as to why you were doing it. His expression shifted, brows furrowing slightly in thought, eyes narrowing. You could practically see the gears turning in his head. "Are you... flirting with me?" he asked, rather bluntly. You would have been offended if you didn't know him so well.
