The dim light of the nearby buildings reflects off Lancelot's jacket and gives Nancy a little warning that he's coming. His radio chitters faintly but he reaches up to turn it down, frowns a little.

"Having a good night?" he prompts her, stopping a short distance away so she doesn't feel too pressured. After all, he has no proof that's she's loitering for the reason he thinks he is. Just an overall gut feeling related to her attitude, the way she's dressed and the way she watches people passing by. His clothing clearly declares him a Police Community Support Officer, so he doesn't carry any weapons or handcuffs, just a notebook and radio (and a frown of concern for her.)
