Kassidy Was digging through the clothes in a closet. He had pants on - low-slung loose things that barely stayed on his hips - but he wasn't looking for a shirt to wear on his bare torso. he was hunting down the Clothes that Catherine had left in the apartment that he just could not wear.
Maybe he should be picking up what was scattered around the small space in preparation for Claire's arrival, but honestly neatness was not one of his virtues, and the kitchen/dining space was spotless from a combination of disuse and dusting.
The clothes were just decorations, sort of.
