Kenzi isn't planning on making friends with this kid any time soon. But it doesn't mean she's going to be outright rude to him 24/7. That would be exhausting.

She's walking them towards the nearest pizza place - and it being Portobello, it'll be within a block or two. Kenzi lets him keep doing his totally discreet glances for a few more seconds before...

"What's on your mind, bucko?"

Sorry, Stiles. She's much more fond of nicknames than any name you mind want to be called.
