He isn't expecting the apology and he cocks his head slightly, looking up at him. It was a fair response, Derek supposes, and he doesn't hold it against Thomas. He just gets up and butts his head against Thomas' hip, circling around his leg once before heading back behind the rock and out of view.

It could have gone a lot worse, he thinks as he shifts back and rolls his shoulders, looking out at the waves as he takes a breath. He pulls on his underwear and then his pants, and he steps out from behind the rock and gives Thomas a tentative smile. The wind ruffles his hair, feeling cool on the bare skin of his chest and back, and he comes back over to sit back on the rock again.

"That's about it," Derek says after a moment, looking Thomas over. "You can ask questions. I'm sure you have some."
