"We were a dreadfully tedious pair to have around," Sherlock smirked. But of course he was similarly glad they had each other. That was all that mattered in the long run. And being stranded on a strange beach with an ocean that blue was far from the worst thing that had happened to them. Disregarding the apparent plane crash beside them they were doing really well.
"I'm sure it's nothing," Sherlock shrugged his shoulder, leaning his forehead against John's. Even that made him feel a little bit better.
"Well, I'm getting a little bit warm sitting on the beach in my pajamas, I'm not going to lie to you," he said softly. "Do you want to go and look for more people? I can go and see if there's any clue as to any civilisation beyond here. Though there must be, some of those people clearly weren't in the crash."
