Storyline

Trip and Hoshi are returning from a visit to a planet where the Klingons once landed. Nothing interesting could be found, but in the shuttle pod back Trip suddenly starts coughing. A while later he collapses. Dr. Phlox finds out they are infected by a silicon-based virus. He estimates that the pathogen will kill them in five hours. Meanwhile an alien species seems to have taken over Mayweather and Reed. They are discussing the behavior of the Humans. For 10000 years they have been observing the reactions to the viruses to measure the intelligence of the infected species. Will the crew surprise them? Written by Arnoud Tiele (imdb@tiele.nl)

Goofs

A silicon-based virus can not replicate in carbon-based life. It will not be able to use its host molecules; which are completely different from a biochemistry point of view. If such a virus exist, no humans or earth species can be infected by such alien virus. See more »

Quotes

[first lines]
["Reed" and "Mayweather" are playing chess]
Alien inhabiting Ens. Mayweather: You win in eight moves.
Alien inhabiting Lt. Reed: You're really starting to get a feel for the game.
Alien inhabiting Ens. Mayweather: 32 pieces, 64 squares - it's not as if it's difficult. Total number of possible outcomes is limited.
Alien inhabiting Lt. Reed: Ten to the 123rd power.
Alien inhabiting Ens. Mayweather: That's what I mean. Chess is so predictable. I'm surprised anyone bothers to play it.

A new refreshing plot.
3 May 2019 | by vodkamate-48063See all my reviews

This was definitely one of the better episodes. Usually there are a lot of episodes with very similar plots scattered throughout the Star Trek series. Voyager, DS9 and Enterprise all seem to recycle. But this one was different. Different and interesting with a sprinkle of ethics on top.
