chunk: As the group makes their way through the damaged ship, they swim through a flooded kitchen. They are chased by two Aliens. One is killed, while the other snatches Hillard. As they escape the kitchen, the Alien returns and blinds Christie, who sacrifices himself to kill the Alien so the others can escape. After Wren betrays the group, Call is revealed to be an android. Using her ability to interface with the Auriga's systems, Call sets it on a collision course with Earth, hoping to destroy the Aliens in the crash. She cuts off Wren's escape route, and directs the Aliens towards him. Ripley is captured by the Aliens, while the others head for the Betty. Wren shoots Purvis and takes Call hostage, demanding that she abort the collision. An injured Purvis attacks Wren and forces his head to his chest just as the Alien embryo he is carrying bursts through his ribcage, causing it to go through Wren's head and kill them both. The survivors shoot the embryo.
