The Betty crew soon encounters Ripley 8. Annalee Call recognizes her name and tries to kill her, suspecting that Ripley 8 may be used to create xenomorphs, but the creatures have already been cloned. The xenomorphs, having matured, escape confinement by killing off one of their own to use its acidic blood to burn through their enclosures, aware of their blood's acidity from said genetic memory. They then capture Dr. Jonathan Gediman and kill a second scientist. They damage the Auriga and kill some of those people who failed to evacuate, including General Perez and Elgyn. Another crew member is captured and cocooned for eggmorphing. Military scientist Dr. Wren reveals that the ship's default command in an emergency is to return to Earth. Realizing that this will unleash the xenomorphs on Earth, Ripley 8, the mercenaries, Wren, a Marine named Distephano, and surviving xenomorph host Purvis, decide to head for the Betty and use it to destroy the Auriga. Along the way, Ripley 8 discovers a laboratory containing the grotesque results of the previous seven failed attempts to clone Ellen Ripley. The surviving one begs Ripley 8 to euthanise her; she complies and then incinerates the lab and its contents.
