CARINA SAYLES: Does it ever bother you?
CARINA SAYLES: Being alone.
AGENT BONNECAZE: ... I must ask you to stop looking into this any further.
MULDER: For what? In case we might turn up any evidence that might support his innocence?
MULDER: So you think that Skinner may have killed the victim in his sleep?
SCULLY: Defending himself against this imaginary old woman. A lot of these patients have no recollection of their nocturnal activities, which might explain Skinner's amnesia.
MULDER: And it's not such a strange story.
SCULLY: It isn't?
MULDER: It's ancient, actually. You may have heard it, although not in such clinical terms. In the middle ages, a visitation like the one Skinner described would have been attributed to a succubus. It's a spirit that visits men in the night, usually in the form of an old woman.
SCULLY: Visits them for sex?
MULDER: Usually. Though sometimes the succubus becomes so attached to the man that she would kill any woman competing for his affection.
MULDER: Maybe that's it. Maybe that's why Skinner's running. He's afraid.
SCULLY: That he did it?
MULDER: That he doesn't know he didn't do it.
SCULLY: Agent Mulder had a theory that the substance could have come from a visitation.
SENIOR AGENT: But you have another explanation?
SCULLY: No. I'm sorry, I don't.
SENIOR AGENT: Do you believe in paranormal phenomena, Agent Scully?
SCULLY: Whatever extreme cases I have encountered I have always viewed through the lens of science. I believe that is why I was assigned to the X-Files and to Agent Mulder.
MULDER: ... I think Skinner's been out-maneuvered, Scully. They found a weakness and they're exploiting it.
SCULLY: But why?
MULDER: To put us in check. You remove Skinner and you weaken us.
SCULLY: I don't understand. Why would they orchestrate such an elaborate scheme just to set him up? Why not just kill him?
MULDER: Well, they already tried that once, and a second attempt would be too obvious, even for these thugs. Anyway, I think Skinner's probably worth more to them alive in disgrace than dead and buried.
