The advert breaks occur as: the Brigadier won't talk to Walmsley as she has enough trouble; as Morgana announces that the sword is waiting for her; when the scabbard slams into the wall next to Walmsley as Mordred summons Morgaine; as the Doctor explains to Ace where Ancelyn comes from in Arthur's tomb; as the Doctor tells the Brigadier he doesn't want to know what Morgaine might have planned when they are in the landrover; as Mordred eascapes, leaving the Brigadier on the ground by Bessie.
