5.5 - Flesh and Stone

From wikipedia

Continuing from the cliffhanger of the previous episode, the destruction of the gravity globe allows the Doctor, Amy, Dr. River Song, and Father Octavian and his clerics to jump into the localised gravity well of the starship Byzantium and escape the horde of approaching Weeping Angels. The Angels follow them into the ship, where the Doctor directs everyone into the ship's oxygen factory, a forest contained within the starship. Before leaving the secondary control room, the Doctor observes a growing, familiar crack, the same one from Amy's bedroom ("The Eleventh Hour"), and determines that it is leaking time energy from which the Angels are currently feeding.
