"David didn't ask me for any tips on the role, but I took my two sons to the filming of his first episode in London, and he was fantastic, very nice and very welcoming," Davison says. "Later on things changed when he married my daughter, and that is rather weird. I don't know if either of us have really come to terms with it. But I think he did a great job in the show, and I do like the fact that I was 'his' Doctor Who when he was growing up."
