Lorelai: Luke, you're mad at Dean from years past. What's past is past. They're a couple now. Do you even remember why you're mad at him?
Luke: He's a punk. That's what I remember. Just look at his history. He broke her heart before.
Lorelai: Well, their problems were mutual. You don't know the whole story.
Luke: He got married and bailed out before the honeymoon was even over.
Lorelai: Well, when you're young, you make mistakes.
Luke: He was pining for Rory, and he got married. That's unstable.
Lorelai: He's 19. Give him a break.
Luke: He doesn't know what he wants. He's proven that. How can Rory trust him now?
Lorelai: Matters of the heart are not science. There are no sure things.
Luke: He's not good enough for her.
Lorelai: Well, who is? Jess?
Luke: No, not Jess. A prince, maybe. One that's in line to be king. You know, not one of those waiting-for-a-brother-to-die ones, but a real one. If not a prince, someone who's gonna be good for her.
