The Doctor's driver and friend. He possesses a very specific set of skills.
Luke Wright is not really a super hero or official member of the Vigil. He met and was “hired” by the Doctor after he participated in a series of extraordinary events in New York. The Doctor offered him and his friend Mei protection from the Russian Moffia and Chinese Triads in exchange for services rendered. Luke serves mainly as the Doctor’s driver and body guard. He also delivers important messages from time to time.
