Several additional time windows are on the ship which lead to different moments in Reinette's life. The Doctor steps through one window to defend Reinette from an android. The android tells Reinette that the androids killed the ship's crew to use their organs for parts to repair the ship. The Doctor discovers that the androids plan to open a time window to Reinette's life at the age of 37, believing that her brain at that age will be compatible with the ship.
