ENT Season 3 Episode 4 Rajiin

Plot

The Xindi Council meet to discuss the progress of Enterprise. Although the Reptilians and Insectoids want to attack the humans, Degra advises them to continue with the plan to build the superweapon. On Enterprise, Sub-Commander T'Pol continues to help Commander Tucker with Vulcan neuropressure sessions. The crew, seeking the formula for a compound to reinforce the ship's hull against spatial anomalies, approach a planet with a vast floating alien bazaar. Captain Archer leads an away team to meet with B'Rat Ud, a chemist who they have met before.
After bartering, he sells them the formula for liquid trellium-D, and also informs them that the Xindi recently visited a merchant nearby. Archer meets the merchant, Zjod, a slaver who tries to sell him a female called Rajiin. Archer refuses and leaves, but Rajiin chases after him. Following a fight between Archer and Zjod, the away team leave with Rajiin, and Archer promises to return her to her home planet. Later she approaches Archer in his quarters, and as she nears him she puts him in a trance, and he no longer remembers her visit. Meanwhile, T'Pol and Tucker attempt to replicate the chemical from B'Rat's formula but the first attempt fails.
Afterwards, T'Pol returns to her cabin and is surprised to find Rajiin inside. She tries to resist, but is soon overcome. Rajiin attempts to flee using the transporter, but is quickly captured and placed in the brig. As Archer attempts to question her, Lieutenant Reed informs him that two Reptilian ships are on an intercept course. Rajiin admits she was gathering information for the Xindi. Reptilians, after running battles with the crew, retrieve Rajiin and take her back to one of the ships. Enterprise attempts to pursue, but the Xindi enter a subspace vortex. Afterwards, the Council convenes again to discuss the development and construction of a new bio-weapon, a project helped by Archer's bio-data that was stolen by Rajiin.
