Episode 34 of "Andromeda"
s02e12 Ouroboros

The crew watches Rev Bem's farewell message, not sure whether or not to pursue him, or let him leave. Dylan says that they should respect Rev's decision to leave, but Harper snaps at Dylan and storms out. He is upset because Rev had promised to remove the Magog larvae from his gut. He writhes in pain, but when he tries to take his medication, it has no effect, as the larvae have grown immune to it, as Trance and Rev had warned him they would. Soon after, Harper enlists in Chief Technical Director Hohne's help, as well as the other Perseids. Harper plans to build a machine that will fold space to remove the eggs, but it's affecting time, as well.
