alien-human hybrids. At Prangen Pharmaceuticals, Mulder tries to get Dr. Calderon, Emily's doctor, to grant access to Emily's medical records; Calderon refuses. Mulder beats him up and threatens him with a gun. Calderon hurriedly leaves the building; Mulder follows, surreptitiously. Scully has imaging tests conducted on Emily. Calderon goes to a large house to see the two Dark Suited Men, one of whom kills him by stabbing him in the back of the neck with an alien stiletto. Calderon's wound bleeds the same green liquid. Both men then morph into Calderon look-alikes. Mulder follows one of the look-alikes as he leaves the house. The results of Emily's tests show her to be suffering from a rapidly-growing neoplastic mass in her central nervous system. The second Calderon look-alike injects Emily with an unknown dark green substance, then escapes by changing his appearance again. Scully believes that Calderon is continuing the treatments, and that the Sims were murdered because they were trying to stop him. Mulder returns to the large house, which turns out to be a nursing home. There, he stumbles upon the real Anna Fugazzi, an innocent elderly lady. The hospital doctor tells Scully that Emily is getting worse. A woman from the adoption agency wants to stop Scully from making decisions for Emily. Mulder connects the names of the women in the nursing home to recent births and finds that Dr. Calderon was treating them. Emily reacts badly to being placed in a hyperbaric oxygen chamber. Mulder finds medical records with Scully's name on them at the nursing home, along with a live fetus in a refrigerated chamber. Mulder finds Calderon entering soon after, and Detective Kresge arrives as well. Mulder and Kresge confront Calderon, who attacks Kresge. Despite Mulder's warning, Kresge shoots Calderon, whose wounds cause him to spew green blood which incapacitates Kresge. Mulder quickly leaves the building to avoid being affected by the blood. Calderon morphs into Kresge, deceives Mulder, and escapes. Mulder returns to the hospital, where Emily has gone into a coma. Days later Emily dies. Mulder visits Scully at the funeral chapel, telling her that Kresge is recovering and all evidence at the nursing home and Prangen is gone. The only evidence left is Emily's body, but the agents instead find sand bags in her coffin along with Scully's cross necklace, which she had previously given to Emily.
