inform him that Soona wants to meet with him and are interrupted by the sound of a gunshot. When Mulder goes out to his apartment hallway to investigate, he finds that one of his neighbors has shot her husband. Soona gives the digital tape to Mulder at a discreet meeting in a park. An excited Mulder returns to FBI headquarters, only to find that the tape is encrypted. Scully believes the encryption is based on the Navajo language and takes the tape in order to investigate. When Skinner calls Mulder to his office to question him about the tape, Mulder physically attacks him. Scully is brought before an FBI panel led by Skinner and is questioned about Mulder's actions. Scully is told that Mulder faces dismissal from the FBI, and that she will suffer a similar punishment if she has lied to them. On Martha's Vineyard, the Smoking Man visits Mulder's father, Bill, and informs him of his son's likely possession of the tape. Scully meets with a Navajo translator, who refers her to a code talker. Mulder is called away to see Bill; when Scully arrives at his apartment, she is grazed by a bullet shot through his window. When Mulder arrives at Bill's residence, his father prepares to reveal the truth about everything. However, Bill is shot and mortally wounded by Alex Krycek. When Mulder contacts Scully, she tells him to flee the scene. After Mulder arrives at her apartment, Scully takes his gun from him while he sleeps. Scully brings the gun to the FBI for comparison against the bullet that killed Bill. When Mulder awakens, he becomes angry and suspicious towards Scully. Later returning to his building, Scully finds his water being contaminated. As Mulder is entering in his building, he spots Krycek, whom he disarms and prepares to kill. However, Scully shoots him to prevent him from doing so, allowing Krycek to escape. Scully brings an unconscious Mulder to New Mexico and, when he awakens, reveals that his behavior was caused by a drug placed into his water supply and that she shot him because if he had killed Krycek, it then would have been harder to prove his innocence in his father's death. She then introduces him to Hosteen, who has been translating the files on the tape. Scully reveals that the tape contains information on both her and Duane Barry. Hosteen introduces Mulder
