The trick with the cigarettes happens so fast that Nathan doesn't have time to do more than blink, then nod his thanks for both the cigarette and the light.
He opens his mouth to answer Aidan's question, but shuts it with a shrug when the detective continues without waiting for an answer. Now's not necessarily the best time for introductions, anyway. He takes a drag on his cigarette and waits for the detective to wind down, blowing smoke off to the side as he nods. "Obviously."
He'd point out that no one seems to be in a rush to do just that, and that he's got no authority to make it happen, but he figures the detective knows that, so he just waits to see if the man has a solution to their joint problem.
