Katniss moves his hands to her hips and Derek gives her a little smile. Her predilection toward using physical gestures to communicate when she becomes concerned that her words aren't doing the job has always been endearing to him. He follows her, most of the time, even if it takes him an extra minute to get there, but she always seems to default to supplementing it like this and he thinks that's sweet.

Derek moves one of his hands off her hip and up to hold the side of her face as he smiles again. "I know. I'm sorry, I didn't mean to take you off guard like that. But if you don't mind it...I kind of like it," he points out. "It doesn't always just have to be because you're upset or scared. Sometimes it can just be because I like you and I want to. Or because you like me and you want to," he adds, letting her know that if she ever feels inclined to initiate in the same way he had this afternoon, she's welcome to do so.
