Além de uma citação do livro:
[Lysa]: “I gave you my maiden’s gift. I would have given you a son too, but they murdered him with moon tea, with tansy and mint and wormwood, a spoon of honey and a drop of permyroyal. It wasn’t me, I never knew, I only drank what Father gave me...”
[Petyr]: “That’s past and done, Lysa. Lord Hoster’s dead, and his old maester as well.”
