SCULLY: How could that be?

MULDER: Exsanguination. If you were to stick a needle into the jugular of any living creature, the heart itself would act as a pump.

SCULLY: Mulder, why would alien beings travel light years through space in order to play doctor on cattle?

MULDER: For the same reason we cut up frogs and monkeys. Besides, they seem to have stepped up their interest.

SCULLY: Time of death was estimated at 2:30 p.m. Same day, only three hours earlier than the Simmons murder.

MULDER: That's Pacific standard time. That makes it the exact same moment.

SCULLY: It appears we have two serial killers working in tandem.

MULDER: No. Serial killers seldom work in pairs. And when they do, they kill together not separately.

MULDER: I don't know. The only thing similar about these girls doesn't seem to be their appearance.

SCULLY: Well, there seems to be the random possibility that two people can have an unrelated likeness.

MULDER: Who both just happened to see their father's exsanguinated. I'd like to get the odds on that in Vegas.

SCULLY: The girls are the one and only link between identical murders.

MULDER: One girl was just abducted.

SCULLY: Kidnapped.

MULDER: Potato, potahto.

DEEP THROAT: Actually I was just in the neighborhood... Wondered if I ever told you about the Lichfield Experiments.

MULDER: No you haven't.

DEEP THROAT: Well, it was the most interesting project. Highest level of classification. All records have since been destroyed. And those who knew of it, denied knowledge of its existence. It existed during the height of the cold war. We got wind the Russians were fooling around with Eugenics. Rather primitively, I might add. Trying to crossbreed top scientists, athletes... to come up with the superior soldier. Naturally, we jumped on the band wagon.

EVE 6: You and you. You have 46 chromosomes. The Adams and the Eves... we have 56. We have extra chromosomes. Number 4, 5, 12, 16, and 22. This replication of chromosomes also produces additional genes. Heightened strength. Heightened intelligence.

MULDER: Heightened psychosis.
