"Noel, it's- it's Arthur, you're alright- w-well, you're alright now--" He moves to kneel in front of him, between Charlie and the fire in case he startles in the worst possible direction. "You passed out in the hall, you were- p-practically frozen through, we got you to our house as fast as we could." He offers Charlie a hand - both, in fact, partly surrender and partly to help him back to his feet if he wants it. "You're alright - it's only been a few hours."
