The crew takes Dr. Arik Soong, a prisoner of Starfleet because he stole the embryos to create these super-humans, aboard, to help find the Bird-of-Prey.

Back in the Bird-of-Prey, Malik starts to question Dr. Soong's judgment when Soong wants to change the embryos' DNA to make them less violent and more human. Malik defies Soong's orders and takes leadership of the Augments. His goal is to create a war between the Humans and Klingon which would enable the Augments to grow in power.

83 :04x07 - The Forge (1)

A tragic incident shakes human-Vulcan relations to the core when a bomb is set off in a protected area of the United Earth Embassy that claims 43 lives, including that of Admiral Forrest. The bomb detonated just before the High Command may have been announcing its intent to conduct joint missions with Starfleet. In the throes of the blast, Forrest actually saved the life of an extremely grateful Soval. As Enterprise is called to Vulcan after the tragedy, Soval comes aboard the ship with the head of the Vulcan High Command, Administrator V'Las, and his security chief, Stel. With the embassy officially on Earth soil, Captain Jonathan Archer is to handle the official investigation. The initial research from the bomb fragments that Mayweather and Reed extricate finds the DNA fingerprint of a Vulcan, T'Pau. She is a member of the Syrrannites, a zealous Vulcan sect that believes in — among other Vulcan taboos — the practice of mind-melding. Syrrannites follow a corrupted form of the teachings of Surak, the father of Vulcan logic who is considered the most important Vulcan who ever lived. A wanted man named Syrran is the sect's current leader. With a Syrrannite now suspected, V'Las announces that Vulcans will take over the investigation.
Guest Stars: Gary Graham (1) as Soval | Vaughn Armstrong as Admiral Forrest | Michael Nouri as Arev | Robert Foxworth as V'Las | Michael Reilly Burke as Koss | Larc Spies as Stel

84 :04x08 - Awakening (2)

As Captain Jonathan Archer and T'Pol reach the Syrrannite compound after crossing the treacherous Forge expanse, they are immediately treated like traitors. But as T'Pol's mom T'Les comes forward, the Syrrannite de facto leader T'Pau backs off a bit, especially after she realizes a dangerous exchange has taken place. Before he died, the Syrrannites revered leader Syrran mind-melded with Archer, giving the captain his "katra.? The Syrrannites regard the "katra? as the living spirit of Surak, a man who died 2,000 years ago and is considered the greatest Vulcan who ever lived. Archer, who has been feeling strangely since Syrran mind-melded with him, is having visions of Surak, and realizes that the notions of katra must be true. Further, while T'Pau tries to extract the katra from Archer through another type of mind-meld, Surak resists, staying firmly planted in Archer's consciousness. Surak has decided that Archer should have this katra; Vulcans cannot possibly understand the severity of dangers they currently face. In trying to protect Vulcans, Surak believes that Archer is his best recourse in saving his race.

85 :04x09 - Kir'Shara (3)

The Vulcans having decimated the Syrrannite compound, Archer — with T'Pol and T'Pau — is driven on bringing the Kir'Shara relic to the Vulcan High Command. V'Las has succeeded in convincing his fellow High Command members that the Andorians will be using Xindi technology to obliterate the Vulcans — although they have a peace accord in place — and is plotting the attack. Because the future-knowing Surak is literally in his mind, Archer knows that time is of the essence; he must bring the Kir'Shara to the High Command before the Vulcans go to war with the Andorians. Unfortunately for Archer and his traveling companions, V'Las is going to extremes to thwart any interference they may cause in carrying out his battle strategy. Further, their showing up and professing the pacifistic views of the Vulcan Syrrannite faction would nullify his framing them for the embassy bombing. To that end, he has sent his henchman Talok to find Archer, T'Pol and T'Pau and "eradicate? them.
