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 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?


It's the second time that Mulder quotes Scully's thesis. See more »


(at around 10 mins) Mulder knocks a hole in the window using a fire extinguisher just before the two men burst into flames. He makes no attempt to put them out using the extinguisher he is still holding. 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!

Back to the Future!
18 September 2006 | by (Washington Terrace, Utah) – See all my reviews

If you haven't seen Back to the Future, you should. It's good, harmless fun. Synchrony explores the time traveling concept as well, but doesn't do as well. It has too many plot holes. I bring up Back to the Future because the teaser to Synchrony plays similarly to the mall scene at the end of Back to the Future, with the emphasis on the clock, the bad weather, and someone running to try to save another's life. Nice homage, but the similarities end there. Synchrony is much more dark and serious. Time travel is always an intriguing concept which is why I still like this episode. However, the actress playing Lisa wasn't all the great. Also, the three big inconsistencies are this: the injection freezes others, but it helps boost the old man? And, the old man has the ability to make himself spontaneously combust? Lastly, at 104 degrees body temperature, Dr. Yonechi was convulsing, but Lisa was still and never convulsed at the same body temperature. The episode also never really explained how Jason Nichols time traveled. We just had some vague Mulder theories. Like I said, time traveling is an ever-entertaining concept which made this episode interesting, but it was filled with too many story holes and inconsistencies to make it a really good x-file.
