He Jests at Scars... (audio story)

 was the fourth Doctor Who Unbound audio story produced by Big Finish Productions. This was the first story not to feature an alternate Doctor; rather it featured Michael Jayston reprising his role as the Valeyard, whom he had last played in 1986's The Ultimate Foe. Bonnie Langford also reprised her role of Melanie Bush. However, like other characters in the Unbound series, these reprisals were of alternate versions of their characters, changed by the scenario presented in the story. The events shown here touch upon what might have happened if the Valeyard had won his trial against the Sixth Doctor and then stole his remaining regenerations.

Publisher's summary
The thing about meddling with time is that one moment something is real, the next, it's been erased. Probability becomes just a possibility. Established truth becomes a theoretical falsehood. Like dominoes, as one timeline falls, the others come cascading down around it. You can engineer new timelines, new possibilities, but before long, the distinction between what is, what was, what might be and what never can be becomes blurred.

Out of this grow myths, lies and legends. The Doctor was one such legend, but no one knows whether he truly ever existed. Well, not now they don't. The Mighty One, ruling the multiverses from the eternal city of Chronopolis, has made sure of that.

Continuity

 * Vansell, introduced in AUDIO: The Sirens of Time and also appeared in PROSE: Divided Loyalties, AUDIO: The Apocalypse Element and AUDIO: Neverland. Three other alternative versions of the character were depicted in AUDIO: Reborn, AUDIO: Disassembled and AUDIO: Annihilation.
 * An alternative version of Ellie Martin appeared in the Sarah Jane Smith audio series.
 * Time Rings first appeared in TV: Genesis of the Daleks.
 * The concept of a time ram first occurred in TV: The Time Monster.
 * Ellie complains that the Valeyard criticises her for carrying weapons unless it suits him. In the proper timeline, the Seventh Doctor's companion Ace frequently raises similar objections. (TV: Remembrance of the Daleks, et al)
 * The Matrix’s projection of the Sixth Doctor’s missed encounter with Mel is inconsistent with their actual first encounter in PROSE: Business Unusual; they didn’t meet at the police station, but the previous day, when the Doctor took her friend Trey Korte back home before realising that he was staying with Mel. However, this story does take place in an alternative timeline, and it is possible that the Valeyard had already changed history in some other way, perhaps erasing Trey or the Nestenes from history.
 * The Valeyard implies that he’s picked up a weapon which belonged to Jack the Ripper, a probable reference to PROSE: Matrix.
 * Vansell observes the Valeyard and Ellie onboard the Hyperion III in the place of the Sixth Doctor and Mel in the proper timeline. The Valeyard leaves Commodore Travers and his entire crew dead as well as leaving the "augmented aubergines" to their own devices. (TV: Terror of the Vervoids)
 * Vansell compares the Valeyard to the inchoate form of the Watcher (TV: Logopolis) but claims that it is unprecedented for such a being to achieve independent sentience, implying either that the Time Lords are unaware of the existence of Cho-Je (TV: Planet of the Spiders) or that he was something else entirely.
 * Vansell refers to the Time Lords once sending the Doctor on an ultimately unsuccessful mission to destroy the Daleks after the Valeyard has altered history by giving the Thals a formula to wipe out the Daleks before their creation. (TV: Genesis of the Daleks)
 * Nula is from the planet Archetryx. (AUDIO: The Apocalypse Element)
 * The Valeyard intends to stop his fourth incarnation from destroying Logopolis and to steal the Master's TARDIS. (TV: Logopolis)
 * The First Doctor, Steven Taylor and "an extinct bird" visited Logopolis after leaving 13th century Kiev. (PROSE: Bunker Soldiers)
 * In various alternative timelines, Mel died of a brain tumour on Earth in 2012, on the colony planet Heritage in the 61st century (PROSE: Heritage) and in the crash of the spaceship Nosferatu II while travelling with Sabalom Glitz (TV: Dragonfire).
 * Vansell observes the Valeyard and Ellie visiting a Silurian bunker in the Galapagos Islands, as the Sixth Doctor and his companion Evelyn Smythe did on 19 September 1835 in the proper timeline. (AUDIO: Bloodtide)
 * The Valeyard tells Mel the names of various companions which whom the Doctor might have travelled in another timeline (namely, the proper timeline): Peri Brown (TV: Planet of Fire), Evelyn Smythe (AUDIO: The Marian Conspiracy), Ace (TV: Dragonfire), Hex (AUDIO: The Harvest), Charley Pollard (AUDIO: Storm Warning) and C'rizz (AUDIO: The Creed of the Kromon).
