Medical examiners observe that Waldo's corpse has a bizarre surgical incision near his eye, and, upon scrutinizing the evidence, John concludes that two different people are responsible for the murders of Waldo and Bryan. Meanwhile, Pete attends one of Gwen's studies at a large laboratory, which hosts both human and animal tests. Gwen has Pete swallow a pill and repeat several words before dismissing him. After, he invites Caroline, a college student who works the front desk at the laboratory, on a date, and the two quickly begin a romance. The following day, a woman finds her son, Timothy, being dismembered in her bathroom by an unknown young woman; she phones police before being stabbed, and manages to tell her friend Mildred over the phone sparse details about the girls' appearance before having her throat slashed.
