- You may be looking for the comic story Museum Piece.
The Doctor arrives in a Velyshaan museum dedicated to the Dalek War. He meets Kalendorf there, an old soldier. They reminisce about the war. The Doctor needed to meet Kalendorf so he could help him make a decision that would destroy the Daleks, albeit at the cost of everything the Doctor holds dear, namely Gallifrey and Time Lords.
A nearby Dalek in a display cabinet is not as dead as it seems and has charged enough power for one shot of its energy weapon. It sees the Doctor and Kalendorf and has to make the decision of which to kill. The Dalek chooses and fires. A nearby school child runs in front of the Doctor and Kalendorf and takes the shot. Kalendorf responds by destroying the Dalek. He turns around to see that the child is dead and the Doctor is nowhere to be seen. Kalendorf concludes that the Doctor had made his decision.
- Reference is made to the Last Great Time War, as the Doctor's choice is linked to his decision not to destroy the Daleks in his fourth incarnation.
- The Doctor is wearing a frock coat.
- The Doctor mentions the planet Tsan.
- The Court of Cenotaphs is a building on Vega VI.
- The Doctor knows that he is going to regenerate soon.
