Travelling through time was a wonderful thing, and quite addictive. The Doctor got to meet the most interesting and influential people, often before they became famous.
Shakespeare was only one of many writers his path had crossed. He’d met Milton and Byron, Mary Shelley and Bram Stoker, H.G. Wells and C.S. Lewis.
And then there was Tolkien. He’d been writing The Hobbit at the time; they’d had an interesting conversation about stuff. The Doctor remembers telling him, ‘Just because someone wanders, it doesn’t necessarily mean they’re lost.’
He’d been chuffed to find Tolkien had paraphrased that idea in his book.
