RICHARD: Interesting. I just realised you have three cups of coffee in the morning …
EMILY: Well, so what?
RICHARD: Nothing. Just an observation, that’s all. That’s a lot of coffee to drink early in the morning.
It seems that Lorelai and Emily have something else in common – they both need their coffee to get through the day. This feels like a callback to the beginning of the Pilot, where Luke asks Lorelai how many coffees she’s had. It’s first thing in the morning, but she’s already had five, and is ordering her sixth.
