On Trantor, Queen Sareth is summoned for a medical examination to determine her fertility, as Brother Day intends to harvest her eggs to produce an heir. Sareth refuses to undergo the procedure until after her marriage to Day, asserting her agency in the face of imperial pressure. During the examination, Sareth openly confronts Demerzel, revealing that she knows Demerzel is a robot and is aware of her secret affair with Brother Day. Sareth's assistant, Rue, urges caution, fearing that pushing the Emperor or Demerzel could be fatal, but Sareth is determined to uncover the truth about her family's murder.

After the examination, Demerzel requests a private meeting with Sareth. Demerzel admits she knows Sareth suspects Day of orchestrating her family's deaths. In a chilling moment, Demerzel not only confirms Sareth's suspicions but also directly states that she herself carried out the murders, warning Sareth that any attempt at revenge will result in her own death. Sareth is visibly shaken, realizing the full extent of the danger she is in and the ruthlessness of her adversaries. She is left emotionally devastated, grappling with the loss of her family and the threat to her own life.

Sareth, now desperate and isolated, secretly meets with Brother Dawn. She confides in him, expressing her horror at the prospect of bearing Day's child and her inability to back out of the marriage. Dawn, who is less hardened than his brother, listens sympathetically. Sareth suggests that Dawn could father the heir instead, seeing in him a chance to preserve a kinder legacy for the Empire. This clandestine conversation plants the seed for a potential coup, as Sareth seeks an ally within the imperial family.

Meanwhile, on Ignis, Salvor Hardin grows increasingly suspicious of the Mentalics' motives. She investigates one of their boats and discovers that all its data has been mysteriously erased. Following the boat's last known route, Salvor swims to the location where Hari Seldon was murdered. There, she finds Hari's lifeless body. Tellem Bond and her guards confront Salvor; Tellem declares Hari's death a necessity and, without further explanation, knocks Salvor unconscious. The episode ends with Salvor beginning to drown beside Hari's corpse, her fate uncertain.

Elsewhere, Hober Mallow's proposal to the Spacers meets resistance, complicating the Foundation's plans. Brothers Constant and Poly face trial, adding to the mounting tensions within the narrative. These subplots underscore the broader political and personal stakes as alliances shift and loyalties are tested.

On the military front, General Bel Riose reports developments to Day and Demerzel, but they interrupt him before he can receive orders to deploy the fleet to Terminus. Glawen, Riose's husband, urges him to mutiny against Empire and side with the Foundation, but Riose refuses, fearing the consequences of failure for both himself and Glawen, as well as the potential chaos that would engulf the galaxy if Empire were to fall. Glawen acknowledges Riose's reasoning, and the two share a moment of understanding, with Glawen reassured that Riose is returning to his true self.

The episode closes with multiple characters at critical junctures: Sareth and Dawn conspire against Day, Salvor's life hangs in the balance on Ignis, and the Foundation's broader strategy faces new obstacles. Each character's decisions in this episode have immediate and potentially far-reaching consequences for the future of the Empire and the Foundation.

At the end of Foundation Season 2, Episode 7, "A Necessary Death," Salvor finds Hari Seldon's dead body underwater on Ignis.

She inspects one of their boats, which has had all its data mysteriously erased. Following the boat's last known route underwater, Salvor discovers Hari Seldon's lifeless body lying submerged. This moment is heavy with tension and foreboding.

As Salvor reaches Hari's corpse, she is confronted by Tellem Bond, the Mentalic leader, accompanied by her guards. Tellem coldly states that Hari's death was a "necessary death," implying it was part of a larger plan or philosophy.
