Connor Trinneer wanted Commander Trip Tucker and Subcommander T'Pol (Jolene Blalock) to try to have a baby if Star Trek: Enterprise season 5 happened, but there is a common misunderstanding regarding the 'rule' that Vulcans can only have sexual relations every seven years. Trip and T'Pol became an unlikely but electric couple starting in Star Trek: Enterprise season 3. The Vulcan Science Officer used to savagely critique good ol' boy Trip, but T'Pol and the Chief Engineer of the NX-01 Enterprise grew close physically and emotionally when she helped him heal from his trauma after an attack on Earth killed Trip's sister, Elizabeth.
