T'Pol receives a message from the Vulcan High Command and tells Captain Archer that he will be called by Admiral Forest sooner to use the Enterprise to help her in a classified mission. Later she invites Archer to go with her because she trusts him. Archer asks for details, and T'Pol explains that she worked in a Security Agency many years ago and she had been assigned to capture six surgically altered Vulcan agents of a group that worked undercover in a corrupt planet and refused to return to Vulcan. However, the former agent Menos escaped from her in Risa, and now he has been located in a planet in the route of the Enterprise. They go to the planet with Travis in the shuttle pod and when they capture the fugitive, T'Pol partially recalls details of her past mission. Archer recalls T'Pol that her assignment is to capture the fugitive, not to judge him.
"The Seventh" is another great episode of the Second Season. The story shows a vulnerable T'Pol maybe for the first time, and how important the wise Archer is for her. I feel that with the final statement of T'Pol, her bonds of trust and loyalty with Captain Archer have increased much more. My vote is eight.
