Joan Redfern

Nurse Joan Redfern, widow of Oliver Redfern, was a nurse at Farringham School for Boys, where John Smith was working during 1913.

Biography
While at his time at Farringham, John Smith fell deeply in love with her. He showed her a journal in which he had written down his dreams. They turned out to be his adventures with Rose, and Martha before he was human. After John Smith became the Tenth Doctor again, he requested she join him as a companion, but she dismissed the idea immediately by asking the Doctor, "If you hadn't decided to come here on a whim, would any of these people have died?"

In an alternative future viewed by both her and John Smith, she became his wife, they had two children and a number of grandchildren as they lived happy lives, and grew old together. (DW: Human Nature / The Family of Blood)

In the true timeline, nearly one century later in the end of 2009 or Spring 2010, Joan Redfern's great-granddaughter Verity Newman published the Journal of Impossible Things as a true story told from Joan's perspective and would tell Joan's story to people wanting to purchase the book, showing that Joan would be remembered. She was visited by the Doctor before he regenerated into his eleventh incarnation. She said that, in the end, Joan Redfern was happy. (DW: The End of Time)
