After encountering Geillis and realizing she is the one who kidnapped Young Ian, Claire and Jamie set out to stop Geillis from traveling to the future through the stones in the cave locals call Abandawe.
Jamie realizes one of his pictures of Brianna is missing and Claire believes Geillis is going after Brianna because of the Brahan Seer’s Prophecy. Before Geillis can go back in time by using Young Ian as a human sacrifice, Claire kills her with an axe to prevent her from going after Brianna.
Claire realizes these are the bones Joe was studying and the warning Margaret gave her.
