Susan Foreman Having Susan on the new series of Doctor Who is a no-brainer, but it still hasn't happened yet. Even current 12th Doctor, Peter Capaldi, agrees. In 2014, Ford visited the set of Doctor Who and met Capaldi. "... he started saying, 'Oh, you should come back!' I said, 'Yeah, I'd love to come back!' " Ford told Doctor Who Magazine. "He was running around the TARDIS saying, 'She's got to come back! She's got to come back!'" We couldn't agree more. BBC, make this happen.
