I threw together this video showing Doctor Who’s ongoing theme of the Doctor and his worst enemies being more similar than he may like. It is also a medium for the show’s ongoing theme that nobody is one-dimensional, and everybody has a “good” and an “evil” side.

Breakdown of each scene and why I included it:

0:00 — Series 1 Episode 6 “Dalek” — The Doctor’s first encounter with the Daleks in the 2005 series, and the first time since the end of the Time War. The exchange sets the scene for the rest of the Doctor’s interactions with the Daleks, and introduces the idea of the Doctor and the Daleks either being the same or sharing traits, with the Dalek explicitly saying so, in addition to the Doctor saying he should “exterminate” the Dalek.

1:30 — Series 1 Episode 6 “Dalek” — Continuing from the previous scene, the Doctor shows his internal hatred of the Daleks and once again tells the Dalek to “Kill yourself. … Why don’t you finish the job, and make the Daleks extinct? Rid the universe of your stink. Why don’t you just die?”, to which the Dalek says “You would make a good Dalek.” This is the first of multiple times a Dalek complements the Doctor on his suitability as a Dalek, or his Dalek-like traits.

2:12 — Series 1 Episode 13 “The Parting of Ways” — The scene has the first allusion in the new series of the Doctor being “The Destroyer of Worlds”, as he must decide if he should kill the Daleks, but destroy the Earth too. When Captain Jack confirms his support for the Doctor, the Dalek Emperor also says “But he will exterminate you!”

3:20 — Series 1 Episode 13 “The Parting of Ways” — The Dalek Emperor explicitly says “I want to see you become like me. Hail the Doctor, the great exterminator!” However, the Doctor is unable to go through with it, choosing “coward” over “killer”.

4:26 — Series 4 Episode 13 “Journey’s End” — The Doctor becomes enraged at Dalek Khan’s prophecy, prompting Davros to say “Oh, that’s it! The anger, the fire, the rage of a Time Lord, that butchered millions!” Davros also tells the Doctor to “Show your companion. Show her your true self” and continue yelling.

4:58 — Series 4 Episode 13 “Journey’s End” — After seeing his “Children of Time” threatening Davros and the Daleks, the Doctor realises what he has turned his companions into. Davros calls the Doctor out on this, and asks how many others have died in the name of the Doctor. See also Series 4 Episode 4 “The Sontaran Stratagem”, when Donna asks the Doctor if he “… turned [Martha] into a soldier?”

6:54 — Series 4 Episode 13 “Journey’s End” — While escaping the collapsing Dalek Crucible, the Doctor tries to save Davros. Davros refuses assistance, naming the Doctor “The Destroyer of Worlds”.

7:25 — Series 5 Episode 3 “Victory of the Daleks” — The Doctor is first introduced to the “Ironsides” in WWII, with one claiming that their ultimate goal is “To win the war.”

7:46 — Series 5 Episode 3 “Victory of the Daleks” — The Doctor once again expresses his desire to “exterminate” the Daleks, explicitly telling Churchill to do so.

8:03 — Series 5 Episode 3 “Victory of the Daleks” — A Dalek once again states their goal is “To win the war”, showing their absolute determination, no matter how long it takes. The Doctor goes on to show his own determination to rid the universe of the Daleks, citing his previous attempts, and again shows his inner hatred of the Daleks, physically striking one repeatedly.

9:44 — Series 5 Episode 12 “The Pandorica Opens” — The Doctor recounts the story of the “… goblin, or a trickster, or a warrior” that is supposedly trapped inside the Pandorica, without realising that the story is remarkably close to most of his adventures. River comments that most “good wizards” in fairy tales turn out to be the Doctor, adding a kind of situational irony that in this story, the Doctor is the villain, and the Daleks (amongst others) are the good wizards.

10:23 — Series 5 Episode 12 “The Pandorica Opens” — The Doctor asks what could need all the security of the Pandorica, and “What could inspire that level of fear?”, then asking “Have we met?” to whatever is inside the box. Again, it turns out that what will be inside the box is in fact himself. The amount of fear being discussed would seem to be close to how the Doctor has previously described the Daleks.

11:01 — Series 5 Episode 12 “The Pandorica Opens” — As he is forced into the Pandorica by the alliance, he realises that he is in fact the warrior that is so feared across the universe, potentially on the same level as the Daleks. The Doctor also tries to convince the alliance that they need his help, which they deny, mirroring the Doctor denying the validity and morality of the Daleks’ mission (to exterminate all life that is different to themselves). This may also relate to future episodes such as Series 6 Episode 7 “A Good Man Goes to War”, when he learns that the word “doctor” to the people of the Gamma Forests means “Mighty warrior”, the Time Lords’ fear of The Hybrid (and their subsequent torturing of the Doctor to learn what it is in Series 9 Episode 11 “Heaven Sent”), and his decision to delete himself from history throughout Series 7.

13:38 — Series 7 Episode 1 “Asylum of the Daleks” — The Daleks reveal both that they find hatred beautiful, and that they admire the Doctor’s hatred for them, revealing that perhaps that is why they have never been able to kill him.

14:13 — Series 7 Episode 1 “Asylum of the Daleks” — The Daleks also reveal, later in the conversation from the previous scene, that their name for the Doctor is “The Predator” due to his behaviour.

14:51 — Series 8 Episode 2 “Into the Dalek” — While trying to turn a corrupted Dalek good, the Doctor allows it into his mind, trying to show it the beauty of the universe. Instead, it sees the Doctor’s hatred of the Daleks, determining that is beauty and going on a murderous rampage. The Doctor is visibly distressed when he cannot seem to convince the Dalek that there is more to him than hatred. The following carnage shows what someone with the same hatred of the Daleks as the Doctor would do, without the Doctor’s restraint on using weapons and killing.

16:27 — Series 8 Episode 2 “Into the Dalek” — The corrupted Dalek sees that the Doctor is not pleased with his “victory”, to which the Doctor says “Victory would have been a good Dalek.” The Dalek responds with “I am not a good Dalek. You, are a good Dalek.” using the word “good” as a homograph, and once again upsetting the Doctor.

17:08 — Series 9 Episode 1 “The Magician’s Apprentice” — Having not yet gone back in time to save Davros from the hand mines, the Doctor rhetorically asks “Davros made the Daleks, but who made Davros?” At this point he thinks he may be the source of Davros’ malevolence, going against his intentions of helping those he comes across to become better people, and creating both his arch-nemesis and the race he so despises.

17:28 — Series 9 Episode 1 “The Magician’s Apprentice” — Davros and the Doctor meet for the first time since Series 4, when Davros says “Doctor … I approve of your new face. So much more like mine.” Once again the similarities are being drawn between the Doctor and both Davros, and the Daleks by extension, this time quite literally. At a more metaphorical level, we see in both previous and future episodes that Capaldi’s Doctor is quite angry, or at least more willing to show it, like the Daleks who channel their anger.

17:42 — Series 9 Episode 2 “The Witch’s Familiar” — Faced with the prospect of Clara being dead, the Doctor threatens the Supreme Dalek with a detached Dalek gun. The Supreme Dalek assumes they are more different than they actually are, stating “The Doctor does not use weapons.” After the Doctor corrects this assumption, the Daleks are visibly afraid, as they are struck with a similar fear to what they usually inflict on others. The Doctor is also aware of this, yelling “Listen to your little hearts beat!”

18:01 — Series 9 Episode 2 “The Witch’s Familiar” — As the Doctor threatens the Daleks and broadcasts his conversation, Missy turns to Clara and says “Listen to that, the Doctor without hope. … Nobody is safe now. … He’ll burn everything, us too.” The allusion sounds remarkably similar to what the Daleks are known to do. Davros proceeds to call the Doctor out on what he is becoming, saying it is “gratifying” to see the Doctor become even more like the Daleks.

18:54 — Series 9 Episode 2 “The Witch’s Familiar” — The Doctor realises that with the cables, he could kill every Dalek on Skaro. The length of his contemplation on committing genocide, “Not in self defence, not as a simple act of war.” in Davros’ words, shows his true nature, as a “good man” should have refused without hesitation.

20:24 — Series 9 Episode 2 “The Witch’s Familiar” — As the sun rises, Davros says he has always admired the Doctor, and that he wishes they could’ve been on the same side. While this is of course Davros laying on the charm to entrap the Doctor, it once again shows that they are similar enough for the Doctor’s arch-nemesis to admire him.

20:52 — Series 9 Episode 2 “The Witch’s Familiar” — Missy alludes to the coming of the Hybrid, stating “The friend inside the enemy, the enemy inside the friend. Everyone’s a bit of both, everyone’s… a hybrid.” Additionally, the statement shows that nobody is simple, everyone has a “good” and an “evil” inside them, and the Doctor is no different.
