"Ah-" he stammers, absently touching his own neck. "No it's--it's fine." It's not that he'd forgotten about the scarf, but he'd just assumed that the loan was going to last longer than an afternoon. New arrival, unprepared for the cold. It might have been an expensive accessory but it's not as if Eliot doesn't have others at his disposal.

He puts a hand up to stop Jack, and offers him an appeasing smile. "You can just borrow it for a while, I really don't mind."
