A lovely epilogue to Once And Future, concerning the Fugitive Doctor having been unknowingly hired to track down and kill the War Doctor. There's some nice callbacks to Big Finish's own history here, with appearances from Vienna and Bernice Summerfield. Bernice, particularly, works very well as the voice of someone who knows the Doctor very well, and is shocked at how different the Fugitive incarnation seems to the usual Doctor. Her horror at the Fugitive Doctor using weapons, ordering a Voord army, and having an armoury onboard the TARDIS sells how much of an outier this Doctor is compared to other incarnations, which is a nice symmetary of the War Doctor, who is also a notably more gung-ho incarnation.

Jonathan Carley as usual is note perfect as the War Doctor, sounding uncannily like John Hurt, and the idea of two Time Lords fighting each other causing the emergence of an Uroboros is a novel one. This is a Multi-Doctor story that feels fresh and distinct from all of the others, and hearing these two incarnations who are more brutish in their approach compared to every other Doctor meet is a lot of fun.
