I think [Clara] has taught him to know himself and to try and understand human beings in a more generous way. I think she brings him an understanding of love and compassion, of the depth of the human soul, and in the form of Jenna, she’s brought me immense comfort and happiness and made my first season as Doctor Who unforgettable as an acting experience, because she’s such a class act. She’s a star and an incredible person. And, yeah, she’s fabulous.
