Seamus was still awake, just, and he nodded - hands dropping to open the button of his jeans and push them down. They tangled against his shoes and he had to kick his feet against the side of the bed to dislodge the lot. In t-shirt, boxers and socks he wriggled his way under the covers and situated his head on the pillow properly. A tiny part of him wanted to throw the blankets back and demand Dean stay, give him something to cuddle, but Dean obviously didn't want to, and Seamus wasn't going to make him.
Instead, he tugged the second pillow down from under his head to wrap his arms around it and squeeze it against his chest. "There," he murmured. "M'tucked." He blinked his eyes open to smile at Dean. "Thanks."
