re: #45 Nyet
I think there is a significant chance it will be someone who is Muslim. Capaldi and Moffat have both said they want to add a little diversity to the companions, and we have had Gay (Jack Harkness), Lesbian (Vastra & Jenny), and Bi (River and Clara) Companions. We have also had 2 companions of Black British origin. A Muslim companion would fit in to that band.
