* [[DontFearTheReaper Don't Fear the Reaper]]: A variant. The Watcher is a sort of representation of the Doctor's upcoming regeneration. He breaths mystery and uneasiness, from his look to his theme music. But in the end, he is helpful, telling the Doctor where to go and merging with him at the end.

* GeorgeLucasAlteredVersion: In the 2019 Bluray release of Season 18 viewers are given the option to watch an updated version of this episode, which features new special effects, replacement of the model footage of the radio telescope in Episode 4 with live-action footage of the telescope at Jodrell Bank, and an additional scene where, after watching his hand slip away from the strut as we do in the original, we see the Fourth Doctor plunging to his death.

The Watcher approaches and merges into his dead body, and turns out to have been a time/space-transcending echo of his next incarnation all along. The Doctor [[TheNthDoctor regenerates]] into a young blonde gentleman, who greets everyone with a smile. The [[Creator/PeterDavison Fifth Doctor]] starts his first day almost drowning in the sheer amount of coat and scarf he's wearing, not to mention chased by some very angry security guards.

* EarlyInstalmentWeirdness: Creator/PeterDavison appears with his natural brown hair, which was quickly changed to blonde to better contrast his appearance with Creator/TomBaker's. Luckily, his role here is so brief that it's barely noticeable.

The sonorous ''bong'' of the TARDIS's cloister bell (its OhCrap signal) makes itself heard, so the Doctor and Adric eventually find their way through the nesting [=TARDISes=] back to the outside world. The Doctor suspects that the multiple [=TARDISes=] thing is yet another devious trick of the Master, and dematerializes at once, bound for Logopolis. Tegan, by now extremely confused, finds her way back to the control room and demands to know what the hell is going on and to be put back in 1981 ''right now'', please -- rather angrily, true, but then again "Sorry I'm late, I accidentally stepped into a spacetimeship that looked exactly like a police box and ended up traveling the universe in the company of an alien with an enormous scarf and a swotty maths geek from another dimension" is, as excuses go, pretty lousy. Especially for one's first day on the job.

* ArtisticLicensePhysics: Though the description of how the heat death of the universe would work is basically correct, the way it's depicted bears no resemblance whatsoever to the actual theory, and in fact is more similar to the "Big Rip" theory.

* FloatingAdviceReminder: Happens twice in Part 4. The first time, while hanging on the Pharos Project's power cable, the Doctor is taunted by visions of [[Recap/DoctorWhoS14E3TheDeadlyAssassin the (decayed) Master]], a [[Recap/DoctorWhoS17E1DestinyOfTheDaleks Dalek]], the [[Recap/DoctorWhoS16E2ThePiratePlanet Pirate Captain]], the [[Recap/DoctorWhoS12E5RevengeOfTheCybermen Cyberleader]], [[Recap/DoctorWhoS12E4GenesisOfTheDaleks Davros]], a [[Recap/DoctorWhoS15E6TheInvasionOfTime Sontaran]], a [[Recap/DoctorWhoS13E1TerrorOfTheZygons Zygon]], and the [[Recap/DoctorWhoS16E6TheArmageddonFactor Black Guardian]]. Then after falling, the Doctor sees visions of his past companions from Sarah Jane to Romana II.

Meanwhile, a plucky young Aussie named Tegan Jovanka is off to her first day of work as a flight attendant, when TheAllegedCar breaks down on the way to Heathrow. Good thing there's a handy police box nearby, so she can call for help. But she hadn't planned on getting ''lost inside''. She completely fails to be impressed by the fact that it's obviously an alien spaceship, and instead decides to go yell at the captain of the thing. Meanwhile, her aunt, who was driving her to the airport, has been murdered by the Master for no real reason.

Of course, it's time for the Master to show up and start mucking about with things. He starts small, with such pranks as shrinking the TARDIS (with the Doctor inside) and throwing a [[SpannerInTheWorks spanner into the endless work of Logopolis]]. Unfortunately, Logopolis can't be restarted once it's stopped, resulting in a rather ''large'' problem for those who still want to, you know, ''exist''. The Master hadn't really counted on accidentally deleting much of the universe, and while Tegan and Nyssa are both horrified at even having to be near him (Nyssa, of course, especially because he nicked her father's body), the Doctor reluctantly agrees to try and help the Master fix the spreading entropy.

Adric and Nyssa, meanwhile, can only watch helplessly, as the encroaching entropy wipes out a potion of the universe. Much to Nyssa's despair it includes Traken.

Landing inside Pharos Project, the Master and the Doctor eventually manage in cooperation to install the backup system and restore balance to the universe. But true to form, the Master decides to double-cross the Doctor; he uses the radio telescope broadcast to a message to all intelligent life in the universe: they must submit to him or else he will knock out the backup system and unleash the entropy field upon everything again.

After a chat with the Watcher inside the deepest parts of the TARDIS, Adric is able to follow the Doctor, and the ducklings cause enough of a distraction to allow the Doctor to muck up the Master's plans. Fortunately, this leaves the larger part of the universe intact. Unfortunately, the Master and the Doctor break out into a fight on top of the Pharos Tower. The Doctor sees visions of his worst enemies attempting to kill him. Clashing on the gantry, the two Time Lords wrestle to the floor. The Master gets up first and bolts to the controls of the telescope. He tilts the radar dish until the gantry completely flips over. Grabbing a cable and desperately trying to hang on to it, the Doctor sees several visions of his various enemies taunting him. Gradually, his strength begins to fail him, and finally his grasp slips, causing him to fall. The cowardly Master runs away sniggering in his TARDIS after this cheap act of murder.

* FinaleCredits: Since Part 4 is Creator/TomBaker's swan song, his face is electronically obscured during the ClosingCredits.

%% * GoOutWithASmile: We get one last glimpse of Creator/TomBaker's big toothy smile before the regeneration.

The universe nearly ends and Creator/TomBaker leaves ''Doctor Who'' after an amazing-- and still unmatched-- seven years and forty-one ([[Recap/DoctorWhoS17E6Shada or forty-two]]) episodes. We're not sure which is more important at this stage.
