"I don't know either. We're pretty bad at this, aren't we?" It's no secret that Derek isn't really all that great at taking care of himself, or being selfish. He looks over at Thomas and cocks his head to the side curiously. "If I win, I get to tell you a secret about me. And you have to really think about it before you react."

It's an odd request, he's sure, but he finds that he wants Thomas to know that part of him. Thomas might freak out or decide he doesn't want anything to do with Derek anymore, but still. He wants him to know.
