A small grin tugs up the corners of Derek's mouth and his eyes crinkle in the corners in a way that only a genuine smile can make them do. "I promise not to laugh; only help you expand your repertoire," he says, holding one hand over his head and raising the other playfully. Of course, he's putting on that playful demeanor, because that's the sort of exchange this one happens to be, but he does genuinely mean that. He won't make fun of her. The fact that she was even willing to try if it wasn't her thing was enough to guarantee that out of him.

"I won't fault you if you laugh. I once mistook a laptop for a book, so..." he says, voice trailing off slightly as his face pulls back in an expression of awkward ownership. "I wish I was joking. So, yeah, if you laugh, I won't even be mad," he adds with a smirk.
