->''"I am the Doctor, [[LeaningOnTheFourthWall whether you like it or not.]]"''
-->-- '''[[CaptainObvious The Doctor]]'''

The Doctor isn't recovering well from [[Recap/DoctorWhoS21E6TheCavesOfAndrozani his regeneration]], suffering mood swings, arrogance, bad temper, and ''terrible'' dress sense. He suddenly decides Peri is evil and tries to kill her, then one mood swing later is full of remorse and declares his intention to find a deserted asteroid and become a hermit. Peri is not much impressed, particularly since he seems to have decided she has to go and be a hermit too.

As luck would have it, however, the deserted asteroid is also a stopping-off point for a group of kidnappers who have just abducted a pair of identical twin geniuses to assist with a sinister plot. It isn't long before the Doctor's rediscovering his enthusiasm for saving the universe from evil telepathic giant slugs.

His dress sense seems to be [[ImpossiblyCoolClothes altered]] [[ImpossiblyTackyClothes permanently]], though.

You can watch it [[http://www.dailymotion.com/playlist/x11buh_tardismedia_the-twin-dilemma here]].

!!Tropes:

* BrokenPedestal: Edgeworth, due to being controlled by Mestor's {{telepathy}} powers.
* ContrivedCoincidence: This deserted asteroid suddenly has an awful lot of people on it, doesn't it?
* {{Deconstruction}}: If this serial aired today, people would interpret it as a high-profile trolling effort. The Doctor regenerates back into William Hartnell, undoing all of his character development thus far, and what's more, the new costume is eye-searingly ugly? By all indications, this was not Nathan-Turner's intention; Colin Baker was interested in returning to a darker, less trustworthy Doctor, and Nathan-Turner cast someone who was the polar opposite of Peter Davison. It's hard to explain the outfit, though... except as a deliberate subversion of the hallowed regeneration makeover.
** Six and Peri Brown are assuredly the most controversial portrayal of the Doctor-Companion relationship yet, with the Doctor threatening to abduct Peri against her will and make her into his au pair.
* DirtyCoward: The Doctor, of all people. He does a SecurityCling to Peri on facing his first {{Cliffhanger}}. He gets better though.
* DoubleMeaningTitle: Anyone who has watched it will think of Romulus and Remus when hearing the title, but anyone who knows it as "the first Sixth Doctor episode" will think of regeneration and his moodswings. Of course, that sentence doesn't apply to most people - any episode with Peri in it is BestKnownForTheFanservice.
* ElmuhFuddSyndwome: The twins both have this... which wouldn't be such a problem if their names didn't both start with "R".
* EstablishingCharacterMoment: The Sixth Doctor strangling Peri makes it clear how unstable this regeneration is starting off. Fortunately, the Doctor gets better.
** Mestor has one when he sentences someone to death by embolism for the first time.
* GrandTheftMe: One of Mestor's powers.
* HeroicSacrifice: Edgeworth
* IHatePastMe:
-->(The Doctor is checking his new appearance in a mirror)
-->'''Doctor:''' Ah. A noble brow. Clear gaze. At least it will be, given a few hours sleep. A firm mouth. A face beaming with a vast intelligence. My dear child, what on Earth are you complaining about? It's the most extraordinary improvement.
-->'''Peri:''' On what?
-->'''Doctor:''' [[Creator/PeterDavison My last incarnation]]. I was never happy with that one.
-->'''Peri:''' Why ever not?
-->'''Doctor:''' It had a sort of feckless charm, which simply wasn't me.
** It's worth noting that while he didn't like it, [[Recap/DoctorWho2007CiNSTimeCrash Ten certainly did]].
** It's also worth noting that this is nothing new to Doctor Who- Multi-Doctor Episodes (The Five Doctors and the Three Doctors, especially) had the vast majority of their interactions be vast amounts of bickering between the Doctors.
* InsufferableGenius: Imagine if there were ''two'' Wesley Crushers, and you've pretty much got Romulus and Remus.
** And if you shove them into one body you'd get the Sixth Doctor!
* ItIsPronouncedTroPAY: A RunningGag in this episode is the different ways in which "Lieutenant" is pronounced, with Peri saying "Loo-ten-ant" (the American pronunciation) and the Doctor and Lang saying "Leff-ten-ant" (the British pronunciation).
* LeaningOnTheFourthWall: The Doctor's speech to Peri near the end is no doubt meant for the audience, as well as her. The Doctor even makes a few good points, [[DroppedABridgeOnHim shame that didn't save him in the end...]]
--> '''Doctor''': And I suggest Peri that you wait a little before criticizing my new persona. You may well find it isn't quite as disagreeable as you think.
* MoodSwinger: The Doctor's moods are completely out of control in this story, as a result of his regeneration.
* MyGodWhatHaveIDone: The Doctor regains his senses just in time to stop his attempt to kill Peri.
* OurGraphicsWillSuckInTheFuture: Perhaps the best example is the ''symphony in higher mathematics'' which is composed of large pixels.
* PettingZooPeople: The Jacondans look distinctly avian, with a helping of BigOlEyebrows and mustaches.
* PlanetaryParasite: The episode featured the Gastropods, a race of nearly indestructible creatures who devastated entire planets, but whose eggs couldn't hatch unless seared by a supernova first, limiting their spread.
* ShoutOut: The Doctor quotes from the epic poem "Excelsior." Also, Mestor is a gastropod version of [[StarWars Jabba the Hutt]].
* SingleMindedTwins: Romulus and Remus
* SpaceClothes
* TeleportersAndTransporters
* ThemeTwinNaming: Romulus and Remus.
* TenMinuteRetirement: The Doctor's short-lived career as a hermit.
* TooDumbToLive: Had Mestor just taken over the Doctor at the end of the story like he claimed he could, he would have ''won''. Instead, he screws around and decides to possess Azmael, a more experienced Time Lord who isn't in the throes of post-regenerative trauma, which leads directly to his defeat.
* WeUsedToBeFriends: Peri's dismay at what the Doctor has become sums it up:
-->'''Peri:''' ''You were almost young! I really liked you! And you were sweet, and--''
-->'''Doctor:''' ''Sweet? Effete! Sweet? Sweet? Sweet? Huh, that says it all!''
** The Doctor has a similar moment with Azmael later on.
* WhatTheHellHero: Peri does not take the Doctor's attempt at strangling her well, not to mention all his mood swings and unpredictable behavior.
* YouLookFamiliar: Dennis Chinnery (Sylvest) previously appeared as Albert C. Richardson in The Chase, and as Gharman in Genesis of the Daleks.
