Amazon - Season 1 Episode 15 Escape

Alex, Andrew and Jimmy go to the caves to check some paintings that feature the way out of the Chosen valley. They notice that someone is watching then, but they can't find who. The elders tell Will that they want to start training him to be an elder some day. Will does not like the idea, but the others decide that, since the Chosen may go as far as necessary to get him back, he must stay in the village. Pia decides to stay and so does Karen to look after Will. Andrew goes to say goodbye to Prudence. She warns him that if he leaves the forest, he will suffer leukemia again and eventually he will die. Andrew changes his mind and stays, so Alex tells him to take care of Adam for him. On the night of the escape, Alex and Jimmy are caught in the forest by Balaam and a few of his men. He was the one watching them in the caves, but he does not want to stop them.
