Martha: Then I can get sectioned!
- All Part of the Show: The Carrionites and the "Expelliarmus!" are mistaken as practical effects.
- And I Must Scream: "I've got a nice attic in the TARDIS where this lot can scream for all eternity, and I've got to take Martha back."
- Arbitrary Skepticism: The Doctor scoffs at the existence of witchcraft, but Martha reminds him that she just discovered that time travel is real.
- Arc Number: This episode only; 14. It turns out to be because the witches' solar system has 14 planets.
- Badass Bookworm: William Shakespeare, The Word-Smith. He didn't plan on fighting witches, but was quick to adapt to the changes brought forth by the Carrionites and the Doctor.
- Bavarian Fire Drill: When the Master of The Revels is killed, the Doctor quickly informs everyone that it's the result of "an imbalance of the humours", and asks for someone to remove the body. This is because he knows the actual answer would start a riot.
- Bizarre Alien Biology: The Carrionite witch Lillith creates a voodoo doll and stabs one of the Doctor's hearts. He gets by well enough on the other one until Martha gets it going again.
- Bi the Way: William Shakespeare.The Doctor: We can all have a good flirt later—
Shakespeare: Is that a promise, Doctor?
The Doctor: Ooh, fifty-seven academics just punched the air.
- Brick Joke:
- "I TOLD THEE SO! I TOLD THEE!"
- When handing out the scripts for Love's Labours Won, Shakespeare tells the performers to give it their all, "Y'never know, the queen might show up", before muttering that she never does. Cue the end of the episode...
- Broken Pedestal: Played for laughs. The Doctor goes into full-on fanboy mode at the prospect of hearing Shakespeare speak, and visibly deflates when what he gets is "SHUT YOUR BIG FAT MOUTHS!" Martha quips, "You should never meet your heroes."
- Comically Missing the Point: The Doctor cheerfully tells Martha she could tell everyone she knows she's met Shakespeare. Martha points out via sarcasm that if she did, she'd be institutionalised.
- Continuity Nod:
- CPR (Clean, Pretty, Reliable): When Lilith knocks him out, Martha starts trying to resuscitate the Doctor... and then she remembers he's got two hearts.
- Death by Sex: The young man at the beginning is lured into the witch's house thinking he's seduced the beautiful young woman. He gets torn to shreds instead.
- Description Cut: The Doctor saying that Shakespeare is a wordsmith and bound to say something wonderful, only for the man himself to just rudely tell everyone to shut up.
- Dirty Old Man: The Master of The Revels is accosted by Lilith looking to get a sample from him to use her magic on. He assumes she's trying to get a feel, and whispers that he'll come back later.
- Doing In the Wizard:
- Once again, the Doctor versus magic. He tries to rationalise Lilith's voodoo doll. She just brushes him off.
- At the beginning of the episode, the Doctor himself accuses Martha of this when she asks how the TARDIS can fly.
- Doomsayer: He's quite delighted that the end of the world is happening, crying: "I told ye so! I told ye so!"
- Drives Like Crazy: Martha is a little alarmed at her first TARDIS trip and asks if you have to pass a test to fly it. The Doctor replies that you do, and he failed it.
- The Exit Is That Way: When the Doctor and Martha stumble out of All Hallow's Way to get to the theatre, Martha tells the Doctor he's going the wrong way. He claims he isn't... cue a quick shot of him running in the opposite direction, yelling "we're going the wrong way".
- Foreshadowing: Martha's concern about old-timey racism was rightly founded in a following episode.
- Grandfather Paradox:Martha: What if I kill my grandfather?
The Doctor: Are you planning to?
- Have We Met Yet?: Inverted — the Queen immediately recognises the Doctor from a meeting that hasn't happened to him yet.
- Historical In-Joke:
- Love's Labour's Won is a lost play today because it was commandeered into a spell to release the Carrionite race. When the spell is reversed, the play vanishes along with the Carrionites.
- The Doctor feeding Shakespeare his own lines. Specifically, it resolves the Brick Joke of the Sycorax set up in "The Christmas Invasion"; Sycorax is a witch mentioned in The Tempest, and where Shakespeare got the name is a bit of an academic mystery — as far as anyone can find she's not a figure from mythology, and if it's a Meaningful Name it's far from obvious what the meaning is. "The Christmas Invasion" used it as the name of an alien species, with no explanation / comment, and in this episode Shakespeare hears the Doctor talking about them and likes the sound of it.
- Shakespeare wrote many sonnets about a "Dark Lady" that scholars have puzzled over for ages. It turns out to be Martha Jones.
- Historical Villain Upgrade: Queen Elizabeth I in the end. While she really did have her faults, ordering her soldiers to murder a man on sight in her presence without a trial was not among them.
- Hoist by His Own Petard: The Carrionites are defeated by Shakespeare using language, their own source of power, against them.
- It Only Works Once: The power of a True Name only works once. That's why Carrionites can only be banished once.
- Leaning on the Fourth Wall: The Doctor's comment about academics punching the air works for his own revelation, but also lampshading that academics watching the show who advocate that view are likely having that reaction.
- Let Us Never Speak of This Again: The two performers who cause a Carrionite to appear while rehearsing.
- Magic by Any Other Name: The Carrionites can fly on broomsticks, kill people by sticking pins in dolls, and use chanting to work the effects of their "word-based science". This is basically magic.
- Magic from Technology: Sort of. The Doctor points out that the Carrionites' powers only seem like magic because Earth's science is maths-derived while the Carrionites instead learned how to manipulate words.
- Magical Incantation: The Doctor instructs Shakespeare to create a counter-spell that will re-seal the Carrionites. He comes up with the following.''Close up this din of hateful dire decay.
Decomposition of your witches' plot.
You thieve my brains, consider me your toy
My doted Doctor tells me I am not!
Foul Carrionites fester, cease your show.
Between the points — Seven six one three nine 0.
Banished like a tinker's cuss,
I sing to thee EXPELLIARMUS!
- Mistaken for Cheating: The landlady of Shakespeare's dwelling walks in on Lilith controlling Will, and assumes that they're up to something. She's annoyed, since it's all but outright stated she and Shakespeare are having an affair already.
- Moment Killer: For once it's not the Doctor who does this.
- Mr. Fanservice: Will Shakespeare himself. It helps that this story happens before he lost his hair. It's lampshaded immediately when Martha notes how different he looks from the portraits, and the Doctor telling him not to rub his hair too much, or he'll go bald.
- Names to Run Away From Really Fast: Mother Doomfinger and Mother Bloodtide. The species name Carrionite as well.
- Noodle Incident: Whatever got the Doctor to be named as Elizabeth's mortal enemy.The Doctor: I can't wait to find out!
- No Sell: Shakespeare is too brilliant for the Doctor's psychic paper.
- Oblivious to Love: The Doctor doesn't realise how There Is Only One Bed can be interpreted; even more what it means when a young attractive woman accepts.The Doctor: There's something I'm missing, Martha. (she turns to lie face-to-face with him, their eyes inches apart) Something really close, staring me right in the face and I can't see it. (pause) Rose would know. That friend of mine, Rose. Right now, she'd say exactly the right thing. (flops back over on his back) Still, can't be helped. You're a novice, never mind. I'll take you back home tomorrow.
Martha: (hurt and angry) Great! (she turns her back on him and blows out the candle)
- Playing Possum: The Doctor does this to convince Lilith to leave after the first stab.
- The Power of Acting: The right word in the right time in the right place stirring the proper emotion can draw on a power as old as the Eternals themselves.
- Rebuilt Pedestal: By the end of the episode, The Doctor is again admiring Shakespeare because personality flaws aside he really is that brilliant.
- Rhymes on a Dime: The witches, whether they're incanting or not, do so in couplets.
- Running Gag:
- "No... no, don't do that." makes another appearance. In this case, Martha's attempt to speak ye olde English with ye shitey accent.
- Within the episode, "I might use that!" when the Doctor gives William an idea or two.
- Subverted with "Rage, rage against the dying of the light", which the Doctor says Shakespeare can't use because it's someone else's — or will be in a few hundred years.
- Sanity Slippage: The man who designed the Globe theatre was driven mad by the Carrionites, after they were done using him.
- Saving The World With Art: The world is saved by iambic pentameter and a Harry Potter quote.
- Sealed Evil in a Can: The Carrionites on two occasions. The three in this episode are trying to release the others and then The Doctor, with help from Shakespeare, pulls all of them back into their can.
- Shakespeare in Fiction: He helps The Doctor save the world from (sort of) witches.
- Sherlock Scan: Shakespeare is very good at picking out the unusual details of the Doctor and his companion, and by the end of the episode has worked out who they are.
- To Harry Potter:
- The Doctor tells Martha, "Wait until you read book 7. Oh, I cried." It's called book 7 simply because the book's title of Harry Potter and the Deathly Hallows hadn't been announced. The fact the book ended up being an emotional read in real life was a mixture of Genre Savvy and lucky guess on the part of the writer. It's also a bit of Writers Cannot Do Math; the previous story was set in 2008, so for Martha the book would already be out.
- The witches are finally destroyed with a shout of "Expelliarmus!" The Doctor reacts to the destruction by shouting, "Good old J. K.!"
- There's one towards Back to the Future.
- The Doctor says that Martha is from Freedonia.
- To Harry Potter:
- Shout-Out: To Shakespeare: The episode contained a veiled reference to Sonnet 57 (among many, many less subtle references, natch).The Doctor: Come on! We can have a good flirt later.
Shakespeare: Is that a promise, Doctor?
The Doctor: Oh, fifty-seven academics just punched the air.
- There Is Only One Bed: There's just one double bed in the room the Doctor and Martha share. The Doctor doesn't find this situation uncomfortable at all.
- True Name: The bane of the Carrionites. It can banish them, but only once.
- Words Can Break My Bones: A Carrionite's strength and weakness is the power of words.
- Weapons-Grade Vocabulary: The witches are finally destroyed with a shout of "Expelliarmus!" The Doctor reacts to the destruction by shouting, "Good old J. K.!"
- Ye Olde Butcherede Englishe: Martha tries this with "Verily! Forsooth! Egads!" The Doctor replies "No... no, don't do that."
- You Are Better Than You Think You Are: Faced with the burden of crafting words powerful enough to bind the Carrionites back into their prison, Shakespeare has a brief moment of crisis when the Doctor boosts him back up by telling him he is the one true genius capable of stopping them.
