Cersei's maid, Senelle, wakes her from a nightmare in which Tyrion is laughing at her while the Iron Throne tears her apart. Ser Osmund and Ser Boros are there to tell her that Lord Tywin is dead. Senelle and Jocelyn Swyft help her dress and freshen up a little. Ser Osmund explains that they discovered a passage in Tywin's room and that Jaime has gone to see where it leads. Ser Loras is guarding Tommen. Cersei sends Boros to make sure Tyrion is still in her cell and accompanies Osmund to Tywin's chambers. Cersei is troubled by Tywin's death, but also pleased that she now holds all the power of Casterly Rock and will not be disregarded. As she climbs the Tower of the Hand, she ponders tearing down the cursed structure. Red Lester offers condolences when she reaches the top. The hall is full of people already, and Cersei is irate that she was not told first as the Queen Regent. Ser Meryn guards the entrance to the bedchamber. Tywin has been brought to his bed. Ser Kevan is trying to pray beside it. Cersei is furious that the quarrel is still embedded in his groin and that he has not been bathed and dressed. She angrily calls for Grand Maester Pycelle, only to learn that he had already come and then left to summon the silent sisters. Cersei realizes that she was summoned last. She angrily calls for Ballabar or Frenken, and two guards, Puckens and Shortear, run to obey. They return with Qyburn. He explains that he was once a maester and treated Jaime, and Cersei orders him to remove the quarrel and prepare the body. Qyburn asks what to do with the other body, and Cersei realizes that Shae is in the bed too. Cersei cannot believe that Tywin would use a whore. When Lord Tytos died, Tywin had his mistress paraded naked through the streets to confess herself a thief and a harlot. Qyburn suggests that perhaps Tywin was questioning her about Sansa, and Cersei eagerly accepts the explanation. When she emerges into the hall, Osney and Osfryd have arrived. She tells them to dispose of Shae and make sure no one knows she was there. She tells them to go through the passage just as Jaime emerges. He reports that the passage is blocked by locked iron gates, and he will need keys. Cersei orders men to knock through walls with hammers if they must but to find the killers. She tells Jaime he must be Hand now, but he refuses. Kevan, Qyburn, Osmund, Osfrey, Osney, and three guardsmen, Puckens, Shortear, and Hoke the Horseleg all overhear the rebuff. Jaime mocks her ability to rule, so she slaps him. Kevan angrily tells them to take their quarrel outside. Cersei is sick of meddling Hands and desides that Tywin's successor must be biddible. She decides to ask Kevan. Cersei suddenly wonders where Varys is and thinks he must have been part of it. She orders Ser Meryn to bring him when Ser Boros returns to report Tyrion is gone. One of the gaolers, Rugen is missing as well, and the guards are asleep. Cersei orders the guards killed. Cersei is suddenly frightened and thinks of a prophecy from her childhood relating to her doom. She closes her eyes and sees Tyrion grinning at her.
