6x18 - Gilmore Girls

Although Rory and Logan are back together, Logan is miserable knowing that Rory hasn't really forgiven him, and he takes off with his friends for another stunt with the Life and Death Brigade. Rory accepts Jess's invitation to attend an open house at his new book store/art gallery/publishing house in Philadelphia. While there, she is surprised to run into Luke, who is accompanying his daughter April on an academic field trip.
