The scent of the candle comforted Seamus as soon as he recognised it. Just the fact that Dean had calmed down enough to find and light it was a good sign. "It's okay," he said. He never needed Dean to apologise, but it seemed churlish not to accept it when he did. "I'll add it to my list of stupid shit not to say." He really did have a mental list, one which had started long before the war, of things he should think before saying.
He approached Dean on the couch. "Room on there for me?" he asked, hoping Dean would be ready for a hug but willing to respect it if he wasn't. He could take his own reassurance from the fact that Dean was still in his flat, rather than across the city in his own or his studio.
