Life of the Doctor

Life of the Doctor was a feature-length episode of the british science fiction television series Doctor Who, and marked the 50th Anniversary of the First Episode's broadcast. It continued onfrom The Name of the Doctor, the finale of Series 7.

David Tennant reprised his role as the Doctor and the mystery of John Hurt's "Forgotten Doctor" was explained. However, apart from Matt Smith's, these were the only Doctors who appeared in new footage (all others appeared through archive material.)

Plot
The Doctor is carrying Clara around his timeline, trying to find a way out. He desperately tries to wake her up. In the distance, he sees a figure. He walks up and finds that the Great Intelligence, not having a body, survived. He walks away. The Forgotten Doctor comes up shortly after, and the Great Intelligence wonders why he never met this incarnation. The Doctor quickly follows in the direction the other one went. A whisperman is sent after him.

Clara wakes up. The Doctor tells her there is a way out, but they will have to go through his own life. She agrees to go through. The Other Doctor momentarily comes up and talks to them before they enter his life. When the Whisperman comes, both of them enter in quick succession.

They first find themselves on Trenzalore, during the battle. It is revealed that Daleks were the Doctor's opponent. The Doctor, wanting to avoid interacting with his own future, finds a way to move back through his timeline. It works, but it will not take them back far. They arrive, still on Trenzalore, before the battle. They see two people standing next to a TARDIS. The other Doctor arrives and tries to talk to the eleventh, but he is ignored. He is given the opportunity to escape after informing the Eleventh Doctor that a Whisperman is coming.
