The Mysterious Virus
1 February 2008 | by (Rio de Janeiro, Brazil) – See all my reviews

While investigating an abandoned Xindi ship on the surface of a planet in the Delphic Expanse, Archer, Reed, Sato and T'Pol are infected with a virus and are transformed in aliens. T'Pol keeps her memory and language, and using the translator, she understands that their mates are seeking the city Urquat. Meanwhile, the Enterprise is under siege of two alien ships with teams of exterminators that want to "neutralize" the infected crew to prevent an outbreak of the virus while Phlox researches the cure using the DNA of T'Pol.

In "Extinction", there is a break in the non-stop action of the other three episodes and Archer, Reed, Sato are transformed in obsessive aliens by a mysterious laboratory virus that changes the DNA of other races to the one that is near extinction without capability of breeding, while the Vulcan T'Pol is only partially transformed. I did not find anything special in this episode. My vote is seven.

Title (Brazil): "Extinção" ("Extinction")
