Lorelai: Hey Luke.
Luke: Lorelai - Hi, where's Rory?
Lorelai: Oh - she's out in the car.
Luke: It was a really nice ceremony wasn't it?
Lorelai: Yeah, it was beautiful.
Luke: What's up?
Lorelai: I just wanted to say something to you in case we don't see each other before you go on your trip.
Luke: Sure, what?
Lorelai: Don't get engaged.
Luke: What? Why? - Lorelai? (Cuts to Luke's apartment where he wakes up with a start...it was just a dream)
