2x15 - Lost and Found
Rory (Alexis Bledel) panics when she suddenly realizes that she lost the bracelet Dean (Jared Padalecki) made for her, and when a suspicious Lorelai (Lauren Graham) catches Jess (Milo Ventimiglia) in Rory's room, she accuses him of stealing the bracelet. Meanwhile, Luke (Scott Patterson) goes a little stir-crazy after living with Jess in the tiny apartment over the diner, and he impulsively buys the building so he can expand.
