They also manage to activate the ship's computer, Zen, who responds to their verbal commands.

Teleport back up Cygnus Alpha-2

Blake is brought back onto the Liberator.

Blake teleports down again, taking a large number of teleport bracelets with which to bring back the other prisoners as a crew for the ship. He manages to reach the cells where the prisoners are being kept and speak to Gan. Gan explains that everyone on the planet has contracted a disease, the Curse of Cygnus, and requires constant medication in order to survive. Blake plans to use the Liberator's medical facilities to replicate the drug and offer the religion's leaders a way off the planet. However, he is knocked unconscious by one of the hooded figures.

Jenna and Avon discover a large number of riches aboard the Liberator and agree to leave orbit if Blake doesn't call back within a certain time frame. Blake is taken to the hooded figures' leader Vargas, who has discovered the teleport bracelets and puts one on. He wants Blake to take him off the planet so he can spread his religion throughout space. He tortures Blake to ensure his compliance, then threatens to sacrifice one of the prisoners and deny them the drug. Blake convinces Gan, Vila and two other prisoners, Arco and Selman, to join him in an escape attempt.

A group of hooded figures bring Gan to be sacrificed but at the last moment they are revealed to be Blake and the others and a fight breaks out. Blake, Vila and Gan manage to grab bracelets but Arco and Selman are killed, as is Kara when she shouts a warning to Gan. Against Avon's wishes, Jenna teleports the group onboard, including Vargas. He admits the Curse of Cygnus is a myth, a simple poison used to ensure compliance, and tries to gain control of the ship. However, when he steps onto the teleport pad, Blake teleports him into space, making Vargas explode. As they evade a Federation patrol, Blake tells his new crew that soon they'll stop running.
