"I was thinking about going to the diner," Derek says, looking over to give Thomas a sly grin before bumping their their shoulders together. "Or are you just trying to get me to cook for you again?"

Derek is comfortable like this with few people, and somehow Thomas has already found himself one of them, It's strange. Well, the entire situation is strange, but Derek doesn't want Thomas to think that he's only growing fond of him because of who he looks like. He just can't think of any way to say that.
