Nepenthe

When Jurati was approached by Oh, the latter used a Vulcan mind meld to reveal the horrifying potential consequences of allowing synthetic life like Soji to exist. Jurati agreed to help destroy her, and ingested a tracking device. Narek now uses that to track La Sirena until a guilt-ridden Jurati takes an injection that places her in a coma and stops the tracking. Elnor's attempts to protect Hugh on the Artifact are unsuccessful when Narissa fatally wounds Hugh. Before dying, Hugh gives Elnor a device to signal Seven of Nine's vigilante group, the Fenris Rangers. On Nepenthe, Picard reunites with his old friends and colleagues William Riker and Deanna Troi, whose son Thad died after the medical procedure he required was banned as part of the synthetic ban. Riker, Troi, and their daughter Kestra give shelter to Picard and Soji until La Sirena arrives.
