Doctor Who: 10 Biggest Lies The Doctor Has Ever Told
The Ninth and Tenth Doctors were the freshest faces who had to deal with the Time War, the loss of Gallifrey and the destruction of the Time Lords. They both chose to deal with this in different ways. For the Ninth Doctor, he was more likely to keep silent on the whole affair. He told Rose that he was the last of his kind, though that would be one of the last times he mentioned it.
The Tenth Doctor, while not exactly starting conversations with it, was a little freer in speaking about it. He told Martha about Gallifrey, describing it as a beautiful paradise. He would go on to describe it to Wilf as well, telling the man about his people, how good and just they were, all while seeming to long for any way home.
However, this turns out to be a romanticized version of the truth. When the Master successfully opens a portal for Gallifrey to break the time lock and return, the Tenth Doctor is terrified. His fantasy is shattered, knowing that the planet had descended into Hell by the last day of the Time War. The Time Lords themselves had broken all of their sacred rules, throwing everything they had against the Dalek fleet.
The Doctor may once have been correct about his people and their ways, though the race that tried to escape the war was a far cry from this dream.
