Malina Rigel-Smythe's third wife
From Tardis Wiki, the free Doctor Who reference
Lady Malina Rigel-Smythe was married to at least three other women. Her third wife encouraged Malina to find a greater pursuit in her life when she began following Dr Suleiman Zorn and the Helios Society. Leela, expressing the same sentiments once Heliotropia proved to be a myth, reminded Malina of her wife. (AUDIO: Shadow of the Sun)
