Dean's breath huffed out of his body as he gave Seamus a sad smile, reaching automatically to run fingers through his hair a couple of times. This time of year tended to bring out he worst in some things. In Seamus' case it was an overzealous need to help everyone else before himself, whereas Dean just tended to get a fiercer round of nightmares.
Since Dean was also making tea for himself through force of habit he picked up the milk, and because he was used to Seamus' habits he smelt it before putting it anywhere near his tea. It was just past the point he really wanted to drink it. He put honey in both lots of tea and brought the mugs over to the sofa, offering one to Seamus and wandering around to stick his own on the table. "That's good," he said, eyes still running over Seamus a few times before he was satisfied that he did appear to be relaxing at least minutely.
"I'm gonna go get food, I'll be back by the time that's drinkable," he said, gesturing at his tea. "If I'm not back and you get worse go yell for Dominic," he added sternly. Not that it was all that stern, he was more worried than actually intimidating.
