* HeyItsThatVoice: It's Creator/DavidTennant! ([[Recap/BigFinishDoctorWho025Colditz Again]])

Dr. Knox, a classic CardCarryingVillain, tells Evelyn and Mary that he's fully aware of who the Doctor is -- in fact, the Doctor is like the Jekyll to his Hyde. The Doctor points out that 1827 is, in fact, thirty years before Stephenson would even be born, let alone write ''DrJekyllAndMrHyde'', meaning Knox is a time traveller, meaning that things are a lot more complicated than they seem.

* AnachronismStew: ''TheStrangeCaseOfDrJekyllAndMrHyde'' is referred to a full 3 decades before it's written. This is a plot point.

* ShoutOut: The Doctor quotes Alfred Lord Tennyson. [[Recap/BigFinishDoctorWho057ArrangementsForWar Again]].
** TheStrangeCaseOfDrJekyllAndMrHyde

* ContinuityNod: The Doctor meets Daft Jamie, and recalls his companion, Jamie McCrimmon.

AKA. "The One Where Creator/DavidTennant Saves The Day By Hugging The Villain to Death"

The Doctor can't wait to meet the men, because however abhorrent they must have been, they were an important part of history and did it ''for science''. Evelyn doesn't agree at all. They soon meet every single HistoricalDomainCharacter in the plot: an alcoholic whore named Mary, a mentally disabled street performer named Daft Jamie (DavidTennant!), Hare (who's trying to get it on with Mary), and Knox. Suspiciously absent, however, is Burke, so team TARDIS goes off to investigate. Also, the Doctor, very nostalgic for daft young Scottish men named Jamie, takes Daft Jamie under his wing.

* HeartIsAnAwesomePower: [[spoiler: Daft Jamie's mental disability leads to two things: he doesn't drink alcohol because it makes him feel weird, and he's able to see through the GroundhogDayLoop. On the one hand, not drinking alcohol means he's gotten infected by TheVirus. On the other hand, when the Doctor tells him that Knox is responsible for making Jamie "famous" in the future, Jamie is so happy that he hugs Knox, spreading TheVirus to him. Just as the Doctor planned.]]

Knox turns out to be a human with a stolen TARDIS (don't ask how -- the episode never really explains it) who was hired by some aliens to do virus tests on humans for medicinal purposes. Sadly, alcohol grants immunity to the virus, so coming to Edinburgh ''really'' wasn't the smartest thing to do. Luckily, a few murders in, Knox realised that he could also just set up a GroundhogDayLoop, keep on murdering everyone over and over, and charge some other aliens to watch. Sadly, this means that the web of time is close to tearing apart. Luckily, Daft Jamie is able to see through the loop, thanks to being InspirationallyDisadvantaged. Even more luckily, Jamie isn't immune to TheVirus because he doesn't drink, so the Doctor simply takes him into the TARDIS, vworps over to a month later (just outside the GroundhogDayLoop), and casually tells Jamie that Knox is the reason Jamie's now famous. Leaving out the part where Jamie's fame is because he's ''dead''. Jamie's so delighted that he hugs Knox to bits... infecting him with TheVirus. The Doctor happily leaves a very scared Knox behind, vworps back to 1827, and drops Jamie off on the street so he can go get killed by Hare and Burke. With the timeline reset, the Doctor has to admit that he hates having to send people to their deaths like that, but that it's all part of the big picture.
