8 Ways Doctor Who Could Actually End
3. The Curator
Speaking of keeping fans happy, it's hard to think of a better ending than this one.
50th anniversary special The Day Of The Doctor introduced a character called the Curator, played by Tom Baker. The Curator is heavily implied to be a future, elderly incarnation of the Doctor, one who is revisiting some of his "old favourite" faces, and has retired from a life of adventure to become the humble steward of the Under Gallery.
As we mentioned, there have been flashes of the Doctor yearning for a normal, adventure-free life, and this is an example of him actually doing it. If the Curator is indeed in the Doctor's future, then this could be right at the end of his life - and, in turn, right at the end of the show - with the character running out of regenerations (or simply not needing to regenerate) and finally growing old.
No matter how the Doctor ends up becoming the Curator, ending things here would simply be perfect. Imagine the scene: we pick up with the Curator walking away after finishing his conversation with Eleven, as seen in The Day Of The Doctor. The camera then follows him - if Baker isn't around, then a body double can be slotted in - as he walks out of the gallery, into that white light. The white consumes the screen, and the show ends.
In many ways, Baker is the Doctor, so having him bring the show home would be truly poetic, and highly emotional for long-time fans.
