  ====Season 5 and 6====
  Myrcella (now much older) is seen walking through the Water Gardens with Trystane, with whom she has fallen in love, while being watched by Ellaria Sand and Prince Doran Martell. Ellaria, furious about Oberyn's death, offers to torture Myrcella and send pieces of her back to take revenge on Cersei, whom she feels is responsible for orchestrating Tyrion's show trial which led to the trial by combat that took Oberyn's life, but Doran refuses to harm her. Myrcella is surprised when her "uncle" Jaime Lannister and Bronn finally meet her as she is with Trystane in the gardens. She is upset after Bronn is forced to knock Trystane unconscious, and resists Jaime's urging to leave with him. The Sand Snakes make a sudden ambush in order to kidnap her. She is nearly taken hostage by Nymeria, but the conflict is interrupted after Areo Hotah arrives with a dozen Dornish guards, imprisoning Jaime, Bronn, the Sand Snakes and Ellaria. Myrcella visits Jaime while he is in custody. Jaime tells her that about the situation with Ellaria. He tells her that he needs to take her home to King's Landing. Myrcella, failing to understand, assures him that Dorne is her home now, and that she will stay and marry Trystane. However, her marriage to Trystane never happens as she is poisoned by Ellaria and the Sand Snakes just before she leaves Dorne with Jamie and Bronn. As she's sailing away towards Kings Landing, she dies in Jaime's arms moments after acknowledging him as her father.
  In Season 6, Episode 2, her body returns home to King's Landing shortly after her death, and her corpse. complete with stones over her eyes, is later seen in the Great Sept of Baelor.
