Prologue (webcast)

was the first prequel to the ninth series of Doctor Who, which was released on 11 September 2015 on the Doctor Who website and BBC iPlayer.
It introduced the confession dial, a device pertaining to the Doctor's secretive past which would play an important role in the climactic events of Series 9, and saw the return of Ohila and the Sisterhood of Karn from The Night of the Doctor, and their first appearance in a post-Last Great Time War setting.
== Plot ==
The Twelfth Doctor has returned to Karn, and discusses the nature of friends and enemies with Ohila, the leader of the Sisterhood of Karn. The two discuss an invitation given to the Doctor by someone who the Doctor has known for a long time, but has been enemies with for all that time.
Ohila does not believe the Doctor when he says he will not visit "him", and continues to question his reasons. Eventually the Doctor says he will go "soon", and gives Ohila a confession dial that he says she knows who to give it to. The Doctor comments that he should go and meditate somewhere and then leaves the meeting spot.
== Cast ==
* The Doctor - Peter Capaldi
* Ohila - Clare Higgins
== Crew ==
* Writer - Steven Moffat
* Director - Hettie MacDonald
* Producer - Peter Bennett
* Executive Producers - Steven Moffat, Brian Minchin
== Worldbuilding ==
* The Doctor claims that an enemy is "just a friend you don't really know yet".
== Story notes ==
* This is the first prequel, mini-episode and webcast to feature the Twelfth Doctor.
* This prologue is included in the shooting script for The Magician's Apprentice that was released by the BBC Writersroom, indicating it was originally intended to be a part of the episode proper but was cut during the editing process. In the script, the scene takes place immediately after Colony Sarff speaks to Ohila and departs.
** The placement of this minisode becomes apparent during the episode itself.
* This is Ohila's first appearance that is contemporary with the show's ongoing narrative, rather than in the Doctor's past.
* The Doctor's line to Ohila, "Look after the universe for me, I've put a lot of work into it", is identical to a line used in the 1999 Comic Relief Doctor Who special The Curse of Fatal Death, a story also written by Steven Moffat. The line in question was spoken by that universe's version of the Twelfth Doctor as he was dying. He asked his companion Emma, and the Master, to do the same.
