"Nothing Lasts Forever" is the ninth episode of the eleventh season of the American science fiction television series The X-Files.
In this episode, Mulder and Scully, while investigating human organ theft, uncover a mysterious cult consumed with macabre rituals.
The operation is interrupted by Juliet, a young woman who kills the surgeons by driving metal spikes through their chests.
The police believe the murders are related to an organ theft ring, pointing out that one of the surgeons had his medical license revoked and was an associate of the Russian mafia.
Scully confirms that all legal organ donations have been accounted for while Mulder has found no trace of illegal sales on the dark web.
Mulder links the killer's message to a psalm about God's vengeance and notices that iron bars matching the murder weapon's distinctive shape have been removed from the church fence.
As Luvenis leaves to steal the remaining organs from the hospital, a cult member offers himself as a sacrifice to sustain the others.
Mulder and Scully arrange for a tracking device to be placed in a heart for Luvenis to retrieve, then follow the signal to Beaumont's house.
As he tries to locate Scully in the basement, he is confronted by Luvenis, who has the appearance and strength of a much younger man after being conjoined to Olivia.
[4] Liz Shannon Miller of IndieWire called the episode a pretty on-the-nose title, but one worth letting rattle around in the brains this week, as preparation for the season finale.
