âThe universe is his mistress and heâs not going to give her up for anyone!â? he joked. âHe finds marriage all rather peculiar, I have to say. To him, spending his whole life with someone is an alien concept.â?
He also said that The Doctorâs relationship with River Song is unlikely to move very far.
âThe Doctor gets to flirt, he just doesnât get all the rubbish stuff. He doesnât have to clean up!â?
âMaybe The Doctor will pack it all in and go and live with River, but I canât see it. I think heâs always going to have the element of a mad man with a box, which I really like.â?
Doctor Who begins again on BBC One on April 23.
