This is the name of a 2nd season episode where we find the chief engineer 'trip' in a moral dilemma. The Enterprise encounters the Vissans, a species with 3 genders. One of the genders occupies only 3% of the population and serve only a single purpose, to produce offspring as a 'Cogenitor' for couples of the other 2 genders.Trip has a problem with the way the Cogenitor is treated, 'it' has the same mental ability as any other member of the Vissan species but is treated as an object with no equal rights.
This is classic Star Trek at its best and the writers of this show "Enterprise" do an incredible job of this one by bringing us a dilemma where everything that appears to be 'right' is completely against the nature of anyone who watches this. This has issues such as Slavery and Human Rights all over it and the episode has a sting in the tale that will send your jaw halfway to the floor.
2: Outgunned
We are an enlightened species, intent on making peaceful contact with alien races, so reluctantly we as humans in our new age of enlightenment we will take the minimum amount of offensive weaponry as possible, OK?Previous Star Trek shows never really made many story lines about weapons and why should they? The USS Enterprise, Voyager and certainly the Defiant were always a good match for any potential enemy they encountered. But here, during humanity's first days in deep space, we see the characters constantly struggling to come with ways to defend themselves. Eventually in one episode, Archer admits that he although his intention to explore peacfully never wavered, 'he needed those weapons, and a whole lot more'
Seeing these Star Trek characters struggling to bring peace and human values to the galaxy without the the desire of being armed to the teeth is an interesting development.
3: Borg
Everyone's favourite Star Trek villain's appear in this show too but hang on, there is a very good reason why. The Ultimate Plot Device!Remember in the movie First Contact when picard fires Quantum Torpedoes at the Borg sphere attacking the surface? Well the destruction of the sphere had sent wreckage to the surface of the Earth (The Arctic) and a few well preserved Borg drones have been preserved in the ice. You can imagine the utter carnage that ensues!
22nd century humans of course do not have the slightest clue how dangerous the Borg are and take nowhere near enough precautions, this makes a great episode for a Star Trek viewer since we already know what these bloody Borg are going to do. Some great action, music and drama make for an excellent Borg episode and of course the last outing of the Borg in the Star Trek franchise ever. Not to be missed!
4. Vulcans
Never have the Vulcan characters been so extensively developed before like they have in this series. We find that mind melding is considered a 'dirty' practice and that there are Vulcan sects such as the 'Syrannites' who do not follow the traditional path and are considered rebels and terrorists. Vulcans during this time struggle to keep their emotions in check when things get serious and they prove to be in some cases very unstable and dangerous given that their technology is way better than Starfleets.5. Humbled
One 1st season episode sees Captain Archer reluctantly having to ask for help from an arrogant Vulcan commander (who is constantly looking over his shoulder) to rescue a shuttlepod trapped inside a comet. The Enterprise is equipped with a magnetic grapple, whereas the Vulcans have a tractor beam. Seeing the Starfleet ship as somewhat puny and simple compared to the Vulcan vessel is again, another departure in typical Star Trek lore.
