Scully: Mulder, these are test results. DNA from the claw nail we found, matching exactly the DNA from the virus you believe is extraterrestrial.
Mulder: That’s the connection…
Scully: Which matches exactly DNA that was found in Gibson Praise
Mulder: Wait a minute…I don’t understand. You’re saying that Gibson Praise is infected with the virus?
Scully: No, it’s a part of his DNA. In fact it’s a part of all of our DNA. It’s called a genetic remnant, it’s inactive junk DNA, except in Gibson it’s turned on
Mulder: So if that were true, it would mean that Gibson is in some part extraterrestrial.
Scully: It would mean that all of us are.
