Luke: Uh, listen, I just want you to know that I had a little talk with Jess earlier.
Lorelai: You did?
Luke: Yes, I did, and I really laid down the rules concerning him and Rory. Trust me, he now knows that I am going to be watching them every second they are together.
Lorelai: Oh good.
Luke: Yup.
Lorelai: You know, they're together now.
Luke: What?
Lorelai: Oh yeah. 'I have to get a part for my car,' 'I'm going to go study' - that's kid code for 'Meet me at the previously agreed upon location far away from my clueless uncle.'
Luke: You're kidding me, right? You don't really think that...damn, they are! They're together. They used the kid code and now they're together!
