The Purge.The episode opens with Æon chasing Bambara, a vicious man who frequently causes injury or death to those he encounters. Æon, ignoring his victims, pursues him through a train and onto a building site. Bambara escapes Æon, killing a construction worker in the process, but is captured for Trevor Goodchild. He inserts a strange robot into Bambara through the man's navel and he suddenly loses his darker side, becoming friendly to those around him and quickly befriending an orphan. Trevor says the robot is a 'Custodian', an artificial conscience of his creation which he hopes to implant in all citizens. Æon then meets up with an organization of women who are opposed to Trevor's project, planning to remove the implanted Custodians and bring the operation to an end. Æon goes after Bambara's Custodian, successfully removing it although she is drugged and captured by Breen forces. Trevor meanwhile takes down the resistance movement, while a bomb planted on the train Æon was on explodes, killing the group's leader. Æon then wakes in the middle of a game show, with many of the resistance members implanted with Custodians acting as 'Hostesses' and Trevor being the presenter with two small twin girls. The object of the show seems to be to prove to Æon that she has a natural conscience. It is then that Bambara bursts in, preparing to kill Trevor. Æon pulls a lever that should instigate Bambara's death, but it only shows 'Game Host Trevor' as a complex robot. It is the audience that pulls a lever and opens a trapdoor beneath Bambara, sending him to his death. Æon leaves, assured by her actions that she has no conscience. But, as she leaves, she sees a Custodian imitating her action with the lever.
