Sherlock wasn't uncomfortable but he also wasn't relaxed. This was too strange, too new for him to sleep like this. Instead he spent his time analyzing the men that lay on either side of him: the sounds of their breathing (John's soft snores and Lestrade's little huffs as he buried his face in Sherlock's hair), the feel of their skin against his body, under his hands, the small movements they made, how they clung to him, trying to reassure themselves he was safe even in sleep. It made Sherlock feel rather odd, but he thought he just might like it.
