The witch told me years ago. She promised me three children and she promised me they’d die. “And gold their shrouds." Everything she said came true.
When exactly did Cersei plan for Myrcella's return and Trystane's death with Balon Swann? And why? To avenge Myrcella's mutilation? Or to simply cancel the betrothal? If latter, why go to the extent of killing one of Westeros's prominent scions? (Even with Cersei's craziness that is show!sandsnakes killing Doran and Trystane level stupid) The reason this plot confuses me is that there is no hint/explanation of it from Cersei's POV. And how did Doran find about it? Taena?
