Seamus' gestures of truce connected in his mind and he began to shake along with his heavy breathing. He still felt angry, but there was also terror creeping in around the edges and his eyes started to dart around the room as he suddenly realised he'd had his back to the door and most of the people. He usually trusted Seamus to watch his back but in this moment that wasn't helping.
He almost didn't hear the words over the roaring in his brain but the word 'flat' made it through and suddenly he moved, dashing down the bar to the opening, checking his rear before moving through to the private area and up the stairs.
Seamus' rooms weren't that big, but they were safe, they were warded and even Dean's panicking brain knew that somehow and his survey was rapid before he parked himself against a wall where he could see the entrance to the flat and have nothing at his back.
