Susana was Dr. Burt's assistant and now will be Guy Carson's. Her family came to America in 1598 with Don Juan de Onate, and she has deep resentment towards being lumped into a "Mexican" category despite her heritage. She is slim built with long black hair. Her eyes are a deep shade of purple, set against her brown skin, and the overall effect is one of extreme beauty, but her attitude is frosty and untouchable.
