Boldly Going: “Demons” and “Terra Prime”

After the season-long arc of the Xindi attack in season 3 of Star Trek Enterprise, season 4 followed with several two and three-part stories. Thanks to a change in showrunner, season 4 saw more stories connected to TOS as a spiritual ancestor. One of the main threads of the final season was establishing long-term peaceful relations with not just the Vulcans, but Tellarites and Andorians as well. Together the four species founded the United Federation of Planets in 2161.

In 2155, several species arrive on Earth to discuss the potential of forming a Coalition of Planets. The Enterprise is recalled to assist and the crew are in attendance for Minister Nathan Samuels opening speech. They’re interrupted by a woman who presses a vial of hair into T’Pol’s hand before collapsing. The hair belongs to someone who has both T’Pol’s Vulcan and Tucker’s human DNA, which is impossible because T’Pol has never been pregnant. Archer vows that they will get to the bottom of this mystery.
