2x21 - Lorelai's Graduation Day
Wanting Lorelai's (Lauren Graham) graduation from business school to be a big event, Rory (Alexis Bledel) secretly invites her grandparents Richard (Edward Herrmann) and Emily (Kelly Bishop) to attend. Lorelai is surprised and touched when her parents show up, but her happiness turns to worry when Rory misses the ceremony because she cut school to spend the day in New York with Jess (Milo Ventimiglia).
