More and more, when he wasn't exploring the forest or the beaches, Castiel found himself lingering in the Winchesters' home rather than wandering the streets as he had the first few months he'd been in Preya. There was a level of intimacy to human routines that he found soothing, especially those of his friends. Sometimes, like tonight, he just liked to sit with Dean and quietly enjoy his company. Cas didn't look away as Dean stood and stretched, but his eyes were drawn to the quick flash of skin at Dean's waist before it was covered up once more.
He only lowered his gaze at Dean's comment on the smell, looking down at the long black and white animal hairs clinging to his clothing still. "I'm sorry," he murmured. The skunk musk really didn't bother him any, but he understood that it could be quite overpowering for humans. It was, after all, intended to be a natural defense. But as Dean stepped past him, Castiel went very still for a moment, processing what the hunter had said next. Come upstairs? Perhaps Dean wanted Cas to watch over him - which he was happy to do, of course, though Dean usually protested Castiel doing any such thing.
At least cleaning up was easy enough. Castiel stood up from the stairway and tugged his coat straight. He swept a tendril of Grace lightly over the fabric, through both the coat and the loose pants and t-shirt, to eliminate any of the offensive odor that might still cling to him. He didn't bother with the stairs then, flying the short distance to rejoin Dean. "Is this better, Dean?"
