Now aboard the mysterious train, Mulder locates the car containing the scientific equipment and what appears to be the autopsy room he saw in the video he purchased. There is also an assassin on board who claims to work for the NSA. When they are locked in, he reveals that there is a bomb aboard which is set to go off and destroy any evidence on the train. Scully meanwhile traces her implant to a medical research facility in West Virginia which she feels provides a logical explanation for what has been happening - rogue medical research by a Japanese scientist working without authority. Mulder remains convinced the work was to create a human-alien hybrid. Written by garykmcd

Scully: What is this place?
Elder #1: This was one of the most frightening places on the earth. A place where society sent its monsters to live in shame and isolation. Now, their disease is all but conquered. Science has eliminated thousands of years of misery.
Scully: I've seen your methods of "elimination." What happened to the man who was with me in the forest? What about the people who were in this room?"
Elder #1: They had been exposed.
Scully: Exposed to what?
Elder #1: The same thing all these victims have been exposed to... victims of an ...

731 the Limerick:

Mulder gets locked in a cart

With one who in the cover-up takes part

He gets the door code

Before the cart will explode

Then X saves Mulder from being blown apart

The second episode in the two parter with Nisei being the first. I don't quite understand the title and I'm not sure if its explained in the episode but I know that I missed it if it is. We rejoin our friend Mulder just after he has jumped onto a moving train and for some reason decided to do so with his cell phone in his hand and so he loses it off the side. I like this episode because of the suspense of being stuck on the train car with a bomb with the NSA guy. It gives the episode a kind of "The Phone Booth" feel to it. I also love X in this episode as I do in pretty much every episode. But I love first of all how quickly and easily he slaps the pistol out of Scully's hand at the beginning. C'mon Scully you do NOT mess with X. Then of course he saves Mulder from being blown to bits at the end. And of course there are the important mythology facts that become known to us. Such as the "aliens" being results of human experimenting and they are just deformed lepers. The tests on abductees taking place on these train carts. I think this is the only time the First Elder of the syndicate makes contact with either Mulder or Scully but we are glad he does because it helps Mulder to believe that there is a bomb actually on the train and saves him from blowing himself to bits. I also really like the teaser with the execution of all the mutant alien human leper things. Very graphic. Oh yeah and don't forget this is another good one for all you Pendrell fans. Anyway all in all 9/10.
