CHRISTOPHER: Come on, Lor. Let’s get out of here, let’s get away from this place. Let’s take Myra and just bolt. Leave a note on the dining room table. ‘Dear Richard and Emily, I don’t belong here, I’m going somewhere else, I’ll call you when I get there. Love, Lorelai.’
This is where this episode’s title comes from, although Christopher says, “Dear Richard and Emily”, while the episode is called “Dear Emily and Richard”.
