ENT Season 3 Episode 6 Exile

Plot

Sub-Commander T'Pol, examining gravitational anomaly patterns, calculates the location of a second sphere within the Delphic Expanse [a], and Enterprise diverts course to investigate. Meanwhile, Ensign Sato is contacted telepathically by Tarquin, an alien that appears to her in human form.
Enterprise soon arrives at Tarquin's planet. He welcomes Archer and Hoshi and explains that he can telepathically read objects, and suggests that Enterprise bring him a Xindi object; they give him part of the weapon used to attack Earth. He adds a condition: he will only help them if Sato agrees to remain with him while he works. They reluctantly agree, and Enterprise departs to investigate the second sphere. Tarquin and Sato discuss many subjects and initially the alien seems trustworthy. She also discovers that he had been watching her telepathically for some time and that she is not the first person to be brought here to provide companionship for him; the graves of four earlier companions lie outside his home.
Meanwhile, Enterprise approaches the sphere, but has to halt its approach due to damage from the spatial anomalies generated by it. The ship sends down a shuttlepod insulated with Trellium-D , and is able to approach close enough to take readings. Archer and Trip return to Enterprise and set course to retrieve Sato. Meanwhile, Tarquin attempts to trick her into staying with him permanently, but she refuses and threatens to destroy a device which enhances his telepathic abilities. He reluctantly agrees to let her go, and later provides Enterprise with the co-ordinates for the Xindi colony that is building a part of the weapon. T'Pol's analysis reveals that there are at least fifty spheres in the expanse region.
