Episode cast overview:
Lieutenant B'Elanna Torres (as Roxann Biggs-Dawson)

After a bumpy start and the help of Torres and Kim, they succeed in a holodeck simulation. When it is presented to Captain Janeway, she is impressed and gives them the go ahead to try it, but traveling faster than warp 10 has never before been attempted. The first run goes very well. Tom Paris manages to cross the warp threshold which means that the shuttle craft in which he is traveling exists simultaneously everywhere. But Tom then disappears and Harry is unable to find him anywhere within five parsecs. Tom somehow manages to return to Voyager through subspace, but there are unforeseen side-effects of his transwarp travel and Tom begins to mutate. The doctor tries to treat him with a type of radiation that will prohibit cell mutation, however this fails and Tom dies. To ... Written by Leila Reid (edited by Jeff L.)

When the mutated Paris carries unconscious Captain Janeway and gently puts her down, the Captain holds her head steady, instead of having it hang down, as it does for an truly unconscious person. See more »


[Paris is delirious]
Tom Paris: Do you cry?
The Doctor: [looks unsure] It's not in my program.
Tom Paris: Shame.
Tom Paris: You know, it's funny. What I remember most about being a kid are the times I spent in my room crying. I liked my room, though. It was quiet in there. People'd leave me alone. I'd keep the door locked, read, play games.
Tom Paris: I lost my virginity in that room. Seventeen. Parents were away for the weekend.
The Doctor: I'll note that in your medical file.

Can this be as horrible as I just read?!
14 February 2015 | by (Bradenton, Florida) – See all my reviews

According to IMDb, this is among the most hated episodes of the series. And, when I read through the six reviews for the show, one was lukewarm and the other five totally hated it. So is this really that bad? After all, there have been so many horrible episodes of the various Star Trek shows! Mind you, I love the shows but I also am honest enough with myself to admit that on rare occasions the Trek shows and films let down the viewers. I am a fan but I am NOT a fanatic!

When the show begins, Paris and a few other crew members are working on trying to achieve warp 10. We are told that in theory this would allow for instantaneous travel ANYWHERE...but is it possible? Well, eventually they are ready to test this outside the holodeck and Paris insists that he be allowed to pilot the shuttle on the attempt. At first, it seems to work...but of course it cannot work perfectly, otherwise the series would come to an end and they'd all be home in the middle of the second season!

What follows reminds me a lot of the remake of "The Fly" but with a lot less coherence. It also wasn't bad...that is until the end. Then, it became completely bat$&#* well as stupid! You really have to see this one to believe it...but I can see much of why folks disliked this was kooky indeed! But is it the worst? I don't think so, as the final episode of the original series featured Kirk getting a sex change and suffering a HUGE menopausal mood shift, a terrible "Star Trek: Deep Space 9" episode involving a baseball game in the holodeck and much of season one and two of "Star Trek: Voyager" at least give it a run for the money as worst episode!
