Derek smiles again and starts on a third box. He really shouldn't stay very long, because if Stiles catches him in this tent, he'll almost definitely guilt him into going back to the kissing booth because this is hardly the "plans" Derek alluded to in order to get himself a short shift, so that he could compromise.

"I'll do one more, but then I should probably get going," Derek says, reaching for another box. He doesn't explain why, but he figures that it doesn't really matter. Sansa doesn't really seem the nosy type and the truth is a little more embarrassing than he'd really enjoy sharing. He won't lie if asked, but all the same.

Another smile pulls up the corners of his mouth. "Well, if you think of something, you let me know."
