Sansa and the rest of the Eyrie are plaugued by Marillion's constant singing in the sky cells. Sansa asks Lord Petyr to make him stop, but Littlefinger says he promised the singer that he could sing. It will be over soon, however, as Lord Nestor is coming to make inquiries into Lady Lysa's demise. Marillion has agreed to confess before the lord. Sansa is afraid that Marillion may tell the truth, but Petyr says it will not matter because it would be their word against his, and Petyr has prepared an incentive for Lord Nestor to side with him. Sansa will have to tell her side of the story too, which frightens her, but Petyr says the lie is necessary to save themselves. Sansa does not fully trust Petyr, but is willing to go along for the moment as he did save her life. Her devious, lying side worries her, however everyone else she cares about is dead so far as she knows and she is isolated and friendless save for Petyr. That night, she is unable to sleep for long due to Marillion's continued singing.

Lord Nestor arrives late in the afternoon with his son, Ser Albar, a dozen knights, and twenty men-at-arms. Lord Petyr, Sansa, and Maester Colemon greet him. After the introductions are over, Petyr sends Sansa to fetch Robert. She finds him in his chambers being dressed by two serving women, Gretchel and Maddy. He has been crying and is a mess. Sansa orders a washbasin brought for Robert, whom she addresses as Sweetrobin. Robert did not sleep well the night before because of the singing and because his door was locked. it was actually Sansa who ordered Lothor to lock the door because Robert has taken to sleeping with her, often nuzzling her breasts or wetting the bed. Sansa and Maddy take Lord Robert ot the great hall, where he receives Lord Nestor. Nestor asks after Lysa, and Robert says Marillion killed her. Ser Marwyn Belmore asks if he saw the deed himself and he says that Petyr and Alayne did. Sansa recounts the tale. Part way through, Robert begins shaking violently while demanding to make Marillion fly, and Lothor is forced to restrain him. When the episode is over, Lothor and Colemon remove Robert from the hall. Lord Nestor accepts the story, particularly since Marillion made many enemies by mocking various nobles and then running to Lysa for protection who showered him with gifts. Mord escorts Marillion, now blind, into the hall, who confesses to the murder. He says that he killed her out of jealous love when he learned she was pregnant with Petyr's child. Mord leads him back out, and Sansa is astonished to see the jailor has gold teeth.¹ Petyr offers rooms and refreshments for his guests and has Oswell lead Lord Nestor's retainers away while he asks Lord Nestor to attend him in private.

Sansa serves Lords Petyr and Nestor in the solar. Nestor informs Petyr that Lord Yohn is on his way to question Marillion and that he will be coming in force with a group including Ser Symond Templeton, Lady Anya Waynwood, Lord Benedar Belmore, Lord Gilwood Hunter, Lord Horton Redfort, Ser Samwell Stone, Lord Uthor Tollett, Ser Damon Shett, Lord Royce Coldwater, and Ser Lyn Corbray. Lord Yohn means to remove Petyr as Lord Protector. Nestor wonders what Petyr will do, and Petyr presents him a decree naming Nestor's branch of House Royce Keepers of the Gates of the Moon in perpetuity. Petyr signed the decree himself, claiming that Lysa was murdered before she could do so. Much later, after Lord Nestor takes his leave, Petyr asks Sansa if she realizes what he did. She says that he gave Nestor the Gates of the Moon in return for his support. Petyr admits it, stating that if he had tried to bribe Nestor outright he would be rebuffed, but that he wanted to be a lord in truth and bequeath something to his son. Sansa realizes that Petyr signed it himself instead of having Robert sign so that if he dies, Nestor's claim will be called into question. Petyr is pleased that she sees the ploy and complements her as his daughter. She protests, but Petyr says she must think of herself as his daughter in her heart or the deception could fail. Sansa is not sure she wants to go that far, but realizes that this is what Petyr wants and lies that she will. That night, Robert comes to her bed to sleep. He asks if Sansa is his mother now, and she replies that she is, figuring that the lie is kindly meant and therefore of no harm.
