Plot summary
Eichhorst's true appearance is revealed when he is shown applying nose, ear, and throat prostheses as well as disguising his eyes and teeth, preparing himself to look more human. The four survivors continue to worsen. Captain Redfern is quarantined, but Eph and Nora are unable to treat him, and his condition deteriorates. The CDC worker Jim Kent meets with Eichhorst, refusing to take any more bribes. Eichhorst states Jim's terminally ill wife will be admitted into an experimental cancer treatment trial in exchange for his continued cooperation. Right after Setrakian is released from jail, Nora seeks him out for information.
He insists the victims' bodies must be destroyed. Elsewhere, Bolivar remains holed up in his penthouse, showing increasingly erratic behavior and strange physical transformations, including his atrophied genitals falling off. After turning completely, Redfern escapes quarantine and flees to the hospital basement and feeds on stored blood. As Eph, Nora, and Jim approach, Redfern attacks. After a struggle, Eph bludgeons him to death with a fire extinguisher.
