A Vulcan who has rejected logic and gone on the run, and whom T'Pring is trying to bring into rehabilitation in 2259 when she and Spock accidentally exchange bodies.
Barjan T'Or appears in the first-season Strange New Worlds episode Spock Amok. He is one of the lapsed Vulcans whom T'Pring, in her work for the Ankeshtan K'til rehabilitation centre, seeks out and persuades to return to the path of logic.
T'Pring has arranged to meet him near Starbase 1, but a ritual meant to help her and Spock understand each other leaves each in the other's body. Spock, looking like T'Pring and accompanied by Christine Chapel, has to keep the appointment in her place.
Barjan T'Or is scornful. He mocks Vulcan tradition and sneers at T'Pring's attachment to a man who is half human. Spock's patience gives out and he knocks the fugitive unconscious, which secures the prisoner but is hardly the reasoned persuasion T'Pring would have used.
