The episode begins with a Flashback Nightmare for Mulder. It's not much of a surprise opening because of the standard flashback effects and the fact that it depicts him as his younger self together with his sister Samantha.
Murder-Suicide: The murder which Mulder might have committed was ruled out as muder-suicide.
Ominous Visual Glitch: Mulder underwent an extreme psycho-treatment to induce his memories of Samantha's abduction. His "memories" (probably hallucinations) were showed in freaky colours with distorted people, and the picture is intentionally grainy.
