After half an hour of psyching herself up, Lorelai goes into the diner and tries to make up her fight with Luke. She has already written him a note to apologise, but Luke refuses to engage with her. He accepts her apology, he offers to get her a coffee and a doughnut, but there is no emotion there, and he barely looks at her (would his resolve crumble if he did?). Lorelai has really hurt Luke, and he cannot go back to how things were before.
