<P> The final episode "These Are the Voyages ..." reveals that T'Pol remained Archer's first officer aboard the Enterprise for a total of 10 years . Her relationship with Trip allegedly ended at some point within a year of the death of their cloned child in 2155 (see "Family", below), although she remained emotionally attached to him and expressed concern that she would never see Trip again after the decommissioning of the Enterprise in 2161 . Trip's death on a minor mission just prior to the decommissioning affected her deeply, and she expressed a desire to meet his parents . </P> <P> She also grew comfortable in confiding in the ship's chef during the years prior to the finale . Dialog in the finale suggests that T'Pol was to be assigned to another vessel following the decommissioning of the Enterprise, implying that she remained a Starfleet officer for some time after 2161 . </P> <P> In the Star Trek novels released following the formation of the United Federation of Planets it is stated that T'Pol was promoted to Captain and given command of the newly commissioned NX - class starship USS Endeavour, NX - 06 . </P> <P> T'Pol's ultimate fate has yet to be revealed . Given a Vulcan's life expectancy of approximately 250 years, it is possible that she is still alive at the time of Star Trek: The Original Series and subsequent films . </P>
