Yvette angrily confronts Leith later, but he assures her that he had no idea who her father was and that he would not have pursued her if he had known, or if he still wanted to be with Greer. Yvette tells Leith that she wants him to spend what may be their final days on Earth with her, asking her to meet him at a certain place so they can sneak away and spend time alone.
Leith intends to pursue her, but is confronted by Greer and tells him to stay away from her. Yvette waits for him and begins to fear he will not turn up, but admits to not having given up hope yet. Unfortunately, she and those she is with are poisoned. Yvette is later buried. Lord Castleroy blames Leith for Yvette's death but Leith assures him he would not have hurt her, for she was a kind and good person.
