Ballrooms and Biscotti (S04E01)

Rory and Lorelai return from their European backpacking trip full of plans for Rory's last week in Stars Hollow before she leaves for Yale. Unfortunately, a scheduling error leaves the college freshman with just two nights at home, and her final evening booked for dinner at Emily and Richard's. Elsewhere, Luke fills Lorelai in on his vacation cruise with Nicole; and Sookie reveals the sex of her unborn child. (The WB)
