While making his escape from the City of Chains taught him a few things, by and large Cullen still moves like he's used to plate armor. Meaning while he's quiet... telltale sounds still wind their way down the cave.

There's a door. Cullen listens: no sign of anything that might indicate that the camp on the other side is occupied. It's worth seeing if there are any supplies. Or dry tinder.

Cullen pulls down his hood, but doesn't undo his jacket just yet. Really, it's a mistake to take the hood off; it'd be better not to be recognizable, after all... but it's just such a pleasure to be dry.
