By the time Dean heard Seamus coming up the stairs he was considerably more calm than when he'd left the bar. There had been pacing and muttering and a lot of very precise breathing but eventually he'd managed to pull out his self-care kit and sit on the sofa, still slightly angled towards the door.
He had looked up at the sound on the stairs, hands still running over a scrap of paper with a stupid exchange Seamus and he had had in class back at Hogwarts on it. The room was full of the scent of the candle he'd lit, sea salt and the sense of warm water filling the air.
"Hey," he said quietly as Seamus came in. "Sorry. I know it was a joke, but logic deserted me for a little bit. I'm doing better now." He gestured to his box, similar to ones he kept at his own flat and the studio, several of the items next to him on the sofa where he'd been holding and using them.
