(Played by Tig Notaro)

Commander Jett Reno was Chief Engineer of the U.S.S. Hiawatha when it crash-landed on an asteroid. She transferred to the U.S.S. Discovery after they were rescued.

She was a widow to a Soyousian wife who died during the Klingon-Federation war, and kept a slender lifeline tattoo around her wrist to remember her.
