[Someone gets very bored at night. Sebastian keeps busy enough during the day - he's gathered enough firewood to last for weeks; he helps with the cooking... not so much with the game hunting so far, if only because the resident Musketeers seem so happy to take care of that by themselves. But the nights are boring. He can't even pass the time reading.
With how insufferably cold it is even in the main room, maybe it's understandable that instead of managing to sleep he slips out into the corridor - not for the first time since the blizzard started - walking carefully so his heels won't click against the floor and wake anyone. Pausing before one of the almost snowed-over windows to look out at the whirling snow. Maybe he could spend the night hunting, after all?]
