Mulder and Scully investigate a accident that was predicted by an old man who accosted the victim a few minutes before to warn him he would be run over by a bus, which is exactly what happens. The man, a university professor, was with one of his students, Jason Nichols when the accident happened. The old man was taken into custody by the campus police but the arresting officer is found frozen to death and mysteriously, is still getting colder. The old man escapes and a visiting Japanese scientist is also found frozen to death. The obvious suspect is Nichols but Mulder begins to suspect that something far more complex is happening.

Did You Know?


The molecule shown on the screen is a form of dichloroethane in which the four hydrogen atoms are replaced with helium. Although helium is highly unlikely to form a molecule in this way, the theoretical compound was simply intended to be something that didn't exist and that would be cold and unstable. See more »


The compound shown on screen twice in this episode is 1,2 dichloroethane. This compound clearly wouldn't match the NMR spectra that was present with Dr. Yonechi, since it would only have one peak versus the many shown in that spectra. Also, 1,2 dichloroethane clearly does not exhibit any of the properties claimed by the characters in this episode. See more »


Mulder: If Lucas Menand never gets hit by that bus, his complaint gets heard before the grand committee, Jason Nichols loses his funding and he never gets to collaborate on his research with Dr. Yonechi. Therefore, this photograph never gets taken because this celebration never happens.
Scully: ...And if your sister is your aunt and your mother marries your uncle, you'd be your own grandpa!

It puts a whole new spin on being your own worst enemy, huh?
24 December 2007 | by (Sandy, UT, United States) – See all my reviews

I love sci-fi time travel stories. Ever since Back to the Future I have wondered what it would be like to travel back in time and try to warn myself about certain things. It wouldn't be an X-Files episode without really weird corpses of course. In this episode we have an old man ranting about predicting the future who is arrested. Later the arresting officer is found dead and frozen yet strangely his body temperature is dropping. The casting in the episode does a really good job of making sure the old Jason and the young Jason look very much alike. Also apparently in the future the cure for bad eye sight has been found so there is hope for all you that wear glasses and contacts. The old man has come back to stop himself and other scientists from doing the research that finds the way that will make it possible for humans to survive time travel. The main problem with time travel stories is they never make logical sense mainly because the consequences of changing the past always present a paradox. If in the future you can travel to the past and then everyone ends up screwing up history then how come history isn't screwed up in the present due to the people from the past coming and screwing it up. There are explanations for this but they are all of course only theories. The best way to understand it at least to me is to look at each reality as one plane of existence. Then when time travel is invented and things in the past are changed they only happen on separate planes of existence. This is easy to understand if you understand the idea of the fourth dimension. But hey I'm not an expert on this at all. The coolest part of this episode is when the Asian guy bursts into flames after he is revived from being frozen. In any case the episode is decent but not my favorite portrayal of the time travel theme. I give it an 8 out of 10.
