  ====Season 7====
  During a meeting with Daenerys' allies at Dragonstone, Olenna displays her initial unease about Tyrion Lannister's plan to attack King's Landing using the Tyrell and Dornish forces, but eventually agrees. After the meeting, Daenerys asks Olenna to stay to talk with her. Daenerys acknowledges that Olenna has joined forces with her to exact revenge for her family, and not out of any loyalty to her. Olenna advises Daenerys not to listen to "wise men" such as Tyrion, as that is how she has stayed alive all these years: ignoring them. She then tells her the lords of Westeros are all sheep, and Daenerys is a dragon, so she should *be* a dragon.
  In "The Queen's Justice", Jaime Lannister seizes control of Highgarden on Cersei's orders. He confronts Olenna, granting her a painless death by poison, putting it in her cup of wine as she watches. She drinks the entire cup all at once with no hesitation, and then admits her responsibility for Joffrey's death, wanting Cersei to know who had done it.
