The Hunt for the Golden Ankh (S04E09)

Title: The Quest for the Golden Ankh Plot: With Praxis back at ORCA, Cass and Brett enlist Winston’s assistance to erase all traces of Neri from Helen's files. Meanwhile, Louis spies on them through the air ducts and alerts Shelby and Hauser, but by the time they intervene, it’s too late—every record is gone. Neri and Jason explore the underwater pyramid, where Neri activates the Shalamorn hologram, revealing a rebel faction on the Ocean Planet that opposes a peaceful migration to Earth. Shortly after, Malakat and Shersheba confront them, revealing their intent to use the pyramid's power to melt Earth's polar ice caps for their people’s arrival. Malakat admits to causing the crash of the spacecraft carrying Neri and her father. He demands the Golden Ankh, but Neri and Jason manage to flee through a water gate, reemerging in the familiar cave in the outback, where Jakamarra awaits.
