Sub-Commander
T'Pol, examining gravitational anomaly patterns, calculates the location of a second sphere within the
Delphic Expanse and
Enterprise diverts course to investigate. 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 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.
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. Tarquin tries to trick her into staying with him 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. ==Production==
