Sevet is T'Pring's father, a mild and deferential Vulcan who attends his daughter's ritual engagement dinner with Spock aboard the Enterprise in the episode Charades.
Sevet appears in Charades, in the second season of Star Trek: Strange New Worlds. He and his wife T'Pril come to the USS Enterprise for the ceremonial meal at which the families of a betrothed couple weigh each other up.
Where T'Pril is sharp and openly scornful of Spock's human heritage, Sevet is gentle and anxious to keep the peace. He defers to his wife throughout, and she corrects him freely.
The evening is made harder because Spock has been turned fully human by aliens and must hide it, with help from his mother Amanda and his shipmates. Spock's later confession that he kept the secret from T'Pring leads her to ask for time apart. Sevet is played by Michael Benyaer.
