Episode 56 of "Lexx"
s04e19 Haley's Comet

The Lexx crew encounter a space capsule filled with a bunch of politically motivated twenty-year-olds (Haley, Amber, Ryan, Josh). They claim that they have gone up in space with the intention of transmitting a message to make a political statement about the dying earth, and globalization. With financing from Haley's trust fund, they were able to pay the Russians to help them get up in space. Stan and Xev decide that they can stay on board the Lexx for the time being as long as they behave. We soon learn that Amber, Ryan and Josh have a hidden agenda to steal the Lexx and do away with the crew. They pretended to buy into Haley's political agendas only as a means to get up into space. When Haley finds out that she has been deceived by her friends, 790 convinces her to kill them off one by one. 790 spots a black pak (a destructive weapon) lodged under the edge of the bridge and instructs her on how to use it. After obliterating Ryan and Amber, she sets her sites on Stan. Stan and Xev race to awake Kai from the cryochamber so that he can protect them, while Josh attempts to fly off in a moth. A skirmish ensues resulting in Haley and Josh simultaneously killing each other. At the end of the episode, Stan, Xev and Kai put 790 in restraints to prevent him from stirring up more trouble.
