While rescuing [[T'Pol]] from a [[spatial anomaly]], [[Jonathan Archer|Archer]] is infected by subspace parasites in his [[cerebral cortex]], resulting in [[anterograde amnesia]]. His condition, reminiscent of [[Alzheimer's Disease]], prevents him from forming new [[long-term memory|long term memories]]. In other words, Archer remembers everything prior to the accident, but any new memories would fade within a few hours. It becomes clear that Archer is not fit for duty, and he is subsequently relieved of his command. [[Admiral Forrest]] of [[Starfleet]] grants T'Pol a [[field commission]] to Captain. Unfortunately, the mission fails. Earth and every human colony is wiped out by the [[Xindi (Star Trek)|Xindi]]. The only surviving convoy of humans is led by ''[[Enterprise (NX-01)|Enterprise]]'' under T'Pol's command to [[Ceti Alpha V]]. Twelve years pass and [[Phlox (Star Trek)|Dr. Phlox]] finds a cure. Unfortunately, the Xindi track Phlox right to the human colony and begin to attack. This, however, corrects the timeline{{ndash}} Phlox discovers that when he uses radiation treatments to kill one of the parasites in Archer's brain, the parasite also vanishes from every medical scan Phlox took{{ndash}} as if the parasite never existed. Phlox and Enterprise crewmen devise a plan in which Archer will be subjected to repeated radiation treatments which will eliminate all of the parasites in his brain; therefore, since Archer will never have been infected, he would have remained captain and possibly prevented Earth's destruction. Unfortunately, the ship is attacked by [[Xindi (Star Trek)|Xindi]] vessels before the treatments can be completed. Phlox noted before that a subspace implosion would also destroy the parasites. Phlox, T'Pol, and Archer set the ship to create a subspace implosion. Their plan works and the ship is destroyed; the subspace parasites are destroyed by the implosion (which exist outside the normal space/time realm). The next scene goes back to Archer in sick bay after being injured from the anomaly. However, since the parasites have been retroactively destroyed, Archer's memory is normal and he remains captain. ==Trivia== {{trivia|date=September 2007}} * At the start of the episode, an allusion is made to [[Scott Bakula]]'s other hit sci-fi series, ''[[Quantum Leap (TV series)|Quantum Leap]]'' (1989&ndash;1993), when [[Jonathan Archer|Captain Archer]] sees himself out of sorts in the mirror. * [[Ceti Alpha V]] is the planet that [[Captain Kirk]] would deposit Khan Noonien Singh on in ''The Original Series'' episode "[[Space Seed]]". Reference is also made to the [[Mutara Nebula]], where the climactic battle between Captain Kirk and Khan occurs in ''[[Star Trek II: The Wrath of Khan]]'' (1983). This is also meant to be a cruel irony as Ceti Alpha V would be forever changed into a wasteland in the 23rd century by the destruction of Ceti Alpha VI. Thus humanity would be doomed regardless. * The Ceti eel does not seem to be a problem for the human colonists; perhaps the creature became a menace after the environment was altered, but that is not consistent with the non-canon novel "To Rule In Hell: The Exile of Khan Noonian Singh", in which the eel was found to cause problems while the ecosystem was healthy. ==External links== * [http://www.startrek.com/startrek/view/series/ENT/episode/2906.html Episode information from STARTREK.COM] {{memoryalpha article|Twilight|Twilight}} {{Time travel stories}} [[Category:Star Trek: Enterprise episodes]] [[Category:2003 television episodes]]
