Wendell rides Cody 2 around town... and he fornicates with it along the way. Everybody else races to the Annihilatrix while the Deceptacles make a stew out of Watley's decapited body in the motel swimming pool. Finally, Killface's alien brethren (and his mother) arrive to inquire about how the Earth has not yet been annihilated.
Valerie kills Sinn and blames Wendell and Arthur. Xander learns he has an illegitimate daughter. She comes to visit after her mother dies from cancer. Xander bribes her never to contact him again. Wendell decapitates Arthur when he tries to propose to Antagone. Antagone finally gives birth to her monster ant baby, which then eats her head.
Killface and Simon attempt to repair the burnt couplings on the Annihilatrix, while Stan and Taquil attempt an escape from their shot-down plane. Sinn and Val ask Watley to kill Antagone (due to increasing strains on their relationships with Antagone). Meanwhile, Wendell is sent by Xander to kill the giant ant baby. Both Wendell and Watley inadvertently fall in love with Antagone.
While Killface prepares for the Presidential debate, Xander makes a few stops with Ronnie before he arrives at the debate. Both Xander and Killface come to realize that neither of them are qualified or allowed to run for the Presidency due to discrepancies they've both overlooked. Killface decides to follow up on his original plan to destroy the world.
