The Doctor: I'm always alright.
Donna: Is "alright" a special Time Lord code for... really not alright at all?
The Doctor: Why?
Donna: Because I'm alright too.
Original air date: June 7, 2008
Written by Steven Moffat.
Donna, our favourite stroppy Londoner, has been having some funny turns recently. As we all know, she was a bit confused and spent a few years in a mental institution. There, she met a nice man called Lee, and now she's happily married with two kids. But lately, she's been having "lost time", and Dr. Moon says everything is fine, and...
But what about the Library of the future, and the people-eating shadows, and River Song and everything? And then we see a familiar person in Donna's world: Miss Evangelista, one of the Red Shirts killed in the last episode. And she tells Donna that none of this is real.
When Donna rips off Miss Evangelista's veil, it reveals that her face has become glitched. The little girl, watching all this on her TV, screams. So do you, because Steven Moffat.
Donna and everyone else aren't really in present-day London. They're in a Lotus-Eater Machine, and the computer is getting a little overloaded. Doing what? Saving all the people, of course... that's where they all went. They got saved... to disk. When the Vashta Nerada arrived, the Library's computer tried to teleport 4022 people out all at once, and the system overloaded. Even the neural echoes of people, briefly captured by their suits' comm systems, get included. Which is how Miss Evangelista now lives on.
The Vashta Nerada usually live in forests. They hatch in trees. Trees... that were made into a planet full of books.
The little girl really was a little girl: related to the founder of the Library, she was merged with the Library's computer as a gift to her when doctors couldn't save her life. Her therapist, Dr. Moon, is quite literally the planet's moon, which contains backup systems that stabilise the computer from above.
While the Doctor, back in the real world, works all this out, a couple more people get eaten by the shadows. The Doctor teaches the Vashta Nerada how to use the suits' comm systems to communicate, but it doesn't exactly help. He does, however, convince the creatures to give him one day, and after that, they can have the planet all to themselves. And River manages to persuade him to trust her by whispering something in his ear...
The Doctor realises that he'll need to pull a Heroic Sacrifice to rescue Donna and the rest of the saved people. River punches him square in the face, handcuffs him to a wall and decides to sacrifice herself instead. Because she knows that if the Doctor sacrificed himself this way he wouldn't be able to regenerate, as the machine's continuous shock would kill him permanently. And now she knows that this is not only his first time meeting her, it's also her last time seeing him... and that from his perspective, their entire relationship will have been based on the moment the Doctor saw her die. The Doctor is powerless to stop her, and asks her why she was able to whisper that one word into his ear — his name. His real name. Her only reply is a final "spoilers!", and with that, she dies.
All the not-dead people are transported back to the library. Donna desperately searches for her Matrix-world husband, whom she truly loves. But just when he sees her, he's teleported away to his own home, and she decides he must have been imaginary. The Doctor leaves River's diary and her sonic behind in the Library —
— she knew his name. He gave her a screwdriver. Why did he give her a screwdriver? Because the screwdriver has a neural relay with her mind's echo stored inside it. The Doctor races back to the little girl/computer and plugs in what's left of River. Her echo, and those of her companions who died today, can live on forever in the Matrix system, being able to live out untold billions of books. In a bittersweet way, Everybody Lives.
- Ascend to a Higher Plane of Existence: The people that were eaten continue living in Cyberspace. Word of God is that Moffat considers this to be as much being alive as most of us get. Their consciousnesses exist inside an electronic library containing the sum total knowledge of a huge slice of the Universe. They can virtually go anywhere, be anybody, and experience anything. Sounds pretty good, doesn't it?
- Ask a Stupid Question...: "It's a screwdriver. It works in the dark."
- Badass Boast: Indirectly, and the more badass for it:"Don't play games with me. You just killed someone I liked, that is not a safe place to stand! I'm the Doctor, and you're in the biggest library in the universe. (pause) Look me up."
- Badass Fingersnap: The Doctor does one at the end, to see if it will open the TARDIS doors as River had said earlier. Cue the biggest smile on his face when it does. He does another one moments later to close the doors.
- Because You Were Nice to Me: Miss Evangelista's reason for wanting to help Donna escape her false reality is returning Donna's kindness when she was alive in the flesh.
- Big Bad: The Vashta Narada.
- Big "NO!":
- Donna lets out several when her virtual children disappear.
- Lux, upon being told that in twenty minutes, the Library will crack like an egg. He then says Doctor Moon will stop it.
- The Doctor, at least four times, after the Girl causes Doctor Moon to disappear and stop the Library's systems from working.
- Big "SHUT UP!": The Girl gives one to her father before causing him to disappear with the TV remote. She later does the same thing to Doctor Moon.
- Body Horror: Miss Evangelista's face is literally glitched. She looks badly photoshopped, or like a walking Picasso painting, which is exactly the point.
- Brain Uploading: "Zero survivors, four-thousand twenty-two saved."
- Broken Record: "We should go. Doctor!"
- The "squareness gun" Captain Jack Harkness used in his first appearance. Word of God says it is the same gun — pilfered by River from the TARDIS where Jack left it at the end of "The Parting of the Ways".
- Donna's line to Miss Evangelista: "If my face ends up on one of those statues..." is this, as at the end of the previous episode, a Node appeared with Donna's face on it, repeatedly saying that Donna had left the Library and had been saved.
- Continuity Nod: The Doctor escaping from being cornered by the Vashta Nerada by dropping through a hole in the floor is quite reminiscent of that time Nine escaped from an impromptu firing squad because he'd been backed up against a lift.
- A very subtle one: "The Moonbase" also had a scene where the Doctor reveals that the enemy are hiding in plain sight inside the room, and pulls aside another character to whisper the information to them.
- Corrupt Corporate Executive: Lux appears to be one of these, until it's revealed what's really been guiding him this entire time.Doctor: CAL is a child? A child hooked up to a mainframe? Why didn't you tell me this? I needed to know this!
Lux: Because she's family! CAL: Charlotte Abigail Lux. My grandfather's youngest daughter. She was dying, so he built her a library and put her living mind inside, with a moon to watch over her, and all of human history to pass the time. Any era to live in, any book to read. She loved books more than anything, and he gave her them all. He asked only that she be left in peace. A secret, not a freak show.
Doctor: So you weren't protecting a patent, you were protecting her...
- Cuckoo Nest: Dr. Moon tells Donna she hallucinated the Doctor, but is now cured. She's actually in a Lotus-Eater Machine.
- Cyberspace: The core of the planet is the biggest library ever; big enough to hold an entire world.
- Dark Is Evil: The Vashta Nerada, being that they exist in shadows, strip humans to the bone and after killing Anita, they say "We are not kind." It can't get more explicit than that.
- Dashed Plot Line: Donna's life inside CAL is a subversion. It looks like we're only being shown selected scenes that take place years apart, but then it turns out that Donna is only experiencing those scenes as well. Only those scenes exist with nothing in between them.
- A Death in the Limelight: With Donna stuck in the artificial reality, River steps up as the companion figure for the last time before she dies in a Heroic Sacrifice at the episode’s conclusion. Most of this and the preceding episode is spent exploring their future dynamic and her history with his next two incarnations. Her only consolation is that her consciousness was the only part saved, onto the planet’s “hard drive”.
- Does This Remind You of Anything?: The scene where Josh and Ella disappear from their beds. Donna loses it completely and starts screaming and sobbing. It looks and sounds reminiscent of a kidnapping or, worse, Outliving One's Offspring. Granted, they're not real, but Donna thought they were.
- The Dreaded: The Doctor's status as this is such that when he tells the Vashta Nerada to use the biggest library in the universe to look him up, they immediately back off afterwards.
- Dreamville: Donna's life inside CAL's system is set in a virtual 21st-century suburbia with no memory of her time with the Doctor. All quite idyllic except for the fact that no time is passing between cuts, she's been given Fake Memories to compensate, and her children are completely identical to all the other kids in the neighbourhood.
- Dumbass No More: Miss Evangelista was a Brainless Beauty in real life. In the virtual world, she is more like The Smart Guy. As she somewhat clinically observes, the same glitch that ruined her looks shifted her IQ by several decimal points.
- Dwindling Party: Following the deaths of Miss Evangelista and Proper Dave in the previous episode, this episode sees the deaths of Other Dave, Anita and River. Only Lux is still alive at the end. However, the consciousnesses of the dead still live on inside the Library's data core.
- Emergency Transformation: Occurs in the backstory. Charlotte Abigail Lux was terminally ill, so her rich family built the Library and uploaded her as the mind of the central computer so she could live forever.
- "Eureka!" Moment:
- "You don't say saved, you say safe!"
- When the Doctor realizes why he gave River his screwdriver, to "save" a copy of her into the virtual world.River: [voiceover] Everybody knows that everybody dies, and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark [the Doctor begins to run back] if he ever, for one moment, accepts it.
The Doctor: Why?! Why would I give her my screwdriver? Why would I do that?
- Everybody Lives: River Song's closing monologue is all about these "blessed days" where everyone is saved and everybody lives. Those stuck in cyberspace come back and are re-teleported without a problem. Everyone that was eaten is transferred to the Library's core through Wi-Fi.
- Exact Words: The message sent by the Library as it was sealed off said "4022 people saved. No survivors." It turns out "saved" was meant literally, as in "saved to the hard drive", explaining the seemingly paradoxical statement.
- Explain, Explain... Oh, Crap!:
- After taking a glance at the room after tinting Anita's visor black, the Doctor pulls River down into a huddle:River: What is it?The Doctor: (quietly) Look, you said there are five people still alive in this room.River: Yeah, so?The Doctor: So... why are there six?
- When the Doctor is able to finally speak to the Vashta Nerada itself, it explains that they haven't come to the library, they were born in it:Vashta Nerada: We. Hatched. Here.The Doctor: But you hatch from trees. From spores in trees.Vashta Nerada: These are. Our. Forests.The Doctor: You're nowhere near a forest. Look around you.Vashta Nerada: These are. Our. Forests.The Doctor: You're not in a forest, you're in a library! There are no trees in a... library.Other Dave: (offscreen) We should go. Doctor!
- After taking a glance at the room after tinting Anita's visor black, the Doctor pulls River down into a huddle:
- Face Death with Dignity: Anita, when she realizes she has two shadows, is pretty calm about it. After she's gone the Doctor tells the Vashta Nerada that her bravery even when scared was something he really liked about her.
- Famed in Story: The Doctor exploits this when Staring Down Cthulhu, telling the Vashta Nerada to look him up as they're threatening him. They do. They back down very quickly.
- Five-Second Foreshadowing:
- After the Doctor tints Anita's visor black, he looks back towards the other archaeologists, only to hold his gaze towards one spot in the back for a few seconds too long. When he then tells everyone else to step back, you can see a fifth archaeologist in the background, right where the Doctor was looking.
- In the scene where Miss Evangelista reveals all the children are identical, if you look closely this can be seen earlier in the scene before she points it out.
- Josh and Ella, Donna's children, have this to say to her after Miss Evangelista reveals the world she's in is not real: "But, Mummy, sometimes, when you're not here, it's like we're not here." "Even when you close your eyes. We just stop." Guess what happens a few seconds later.
- Dr. Moon maintains the dream-world's integrity at several points, but it doesn't dawn on what he represents until the Doctor is told that the moon that's rising in the sky isn't real, but an artificial doctor moon, which maintains the library database. He's the virus checker; a therapist for a computer.
- Lux accuses the Doctor and River of arguing Like an Old Married Couple.
- When River's about to make her Heroic Sacrifice, there's this exchange. Think about it very carefully.The Doctor: I'd have a chance! You don't have any!
River: You wouldn't have a chance and neither do I!
- As River is describing the last time she encountered the Doctor before coming to the library, she says "the real you", before correcting herself to "the future you", signalling that it's a different Doctor who gets to know River better and who gets to say the last goodbye.
- Four Is Death: Other's Dave's line of "We should go. Doctor!" is said four times before the Doctor realizes he was killed by the Vashta Nerada and the words are being spoken through his neural relay.
- Freudian Slip:Donna: I made up the perfect man. Gorgeous, adores me, and hardly able to speak a word. What's that say about me?
The Doctor: Everything. [Beat] Sorry. Did I say "everything"? I meant to say "nothing". I was aiming for "nothing". I accidentally said "everything".
- Heroic BSoD: The entire third act is CAL having a mental breakdown after finding out about her reality.
- Heroic Sacrifice: River Song wires herself up the Library's computer system to allow it to use her personal memory. This kills her stone dead.
- Hidden Heart of Gold: Strackman Lux, set up as a paranoid, uncooperative type obsessed with patents and IP, but it's all a front to keep CAL safe, who is his child-like aunt. He's actually shown to be quite a nice guy after he reveals what CAL is to everyone.
- Holodeck Malfunction: When the Vashta Nerada hatched, CAL initiated an emergency teleport on everyone in the Library. However, there was nowhere to send them. Thus, she "saved" them inside herself. However, this took up too much memory, making her forget about her status as a computer, so when she begins to remember, things start going haywire.
- Hope Spot: Donna really loves her virtual husband, and promises to look for him in the real world as she's yanked out of the computer system. In the real world as everyone is restored, she asks after him, is told no one by that name was in the Library, and unhappily concludes that — like her children — he was never real. However, he sees her and tries to call out her name, but is halted by his stutter and is teleported home before he can reach her.
- Iconic Item: The Doctor is shocked to find his future self has given his sonic screwdriver to River. As she's about to die, River realizes why.
- I Know Your True Name: The Doctor doesn't trust River Song, so to facilitate cooperation she whispers his true name in his ear. This makes him trust her immediately.
- Informed Attribute: CAL "loved books more than anything", but we never see her do any reading. It's justified because she's not in her right mind and has forgotten everything about her life before the shadows came.
- Insane Troll Logic: "If he dies, I'll kill him!"
- Kinky Cuffs: Implied.The Doctor: Why am I handcuffed...? Why do you even have handcuffs?!
River: [smirks] Spoilers.
- Leaning on the Fourth Wall:
- The scenes appearing on CAL's TV, complete with music. She, like many of the viewers, spends a good part of the episode clutching a pillow and trying not to scream.
- Time in the computer progresses "like a dream" — people just mention where they're going to be, and then they're there. In other words, it's like television. Cutting between scenes in a conventional way, and then revealing that that's how the characters are experiencing it, adds a meta level to the are-you-sure-you-know-what-is-and-isn't-real theme.
- Light Is Good:
- Everyone wearing a white suit who isn't killed by the Vashta Nerada. River is probably the biggest example.
- Also the clothes of River, both Daves, Anita and Miss Evangelista after River is uploaded to the Library's data core.
- Light Is Not Good: The white suits and helmets of anyone chasing the group after being killed by the Vashta Nerada, with Proper Dave being the most prominent.
- Like an Old Married Couple: Strackman Lux interrupts an early argument between the Doctor and River thusly:"Oh, for heaven's sake! We're all going to die, right here, right now, and you're squabbling like an old married couple!"
- Literal-Minded: The computer. When it said "4022 people saved, no survivors", it meant it literally. It saved them to the hard drive.
- Living Shadow: Invisible air piranhas, who are very light-sensitive (or maybe just appear as shadows, and are very slow-moving) but can strip the flesh from a chicken leg in the time it takes to fall to the ground.
- Lotus-Eater Machine: The world created by CAL is a virtual reality contained within a gigantic hard drive.
- Mass "Oh, Crap!":
- Everyone when the Doctor points out that although River said there were five people still alive in the room they are in, there are actually six, as Proper Dave has caught up to them.
- The Doctor, River and Lux when informed the Library is going to self-destruct in twenty minutes' time.
- Meaningful Background Event: Right as the Doctor is learning where the Vashta Nerada came from, Other Dave starts looking upward in the background before the camera pans slightly to the left, removing him from the shot. He isn't seen again for a couple minutes, but can be heard saying the same thing four times in a row.Other Dave(?): We should go. Doctor!
- Meaningful Echo:
- Meaningful Name:
- CAL is the initials of the girl's full name: Charlotte Abigail Lux.
- Dr. Moon is the doctor moon.
- Medium Awareness: Donna starts noticing the episode's editing when she's in the computer. This is because the cuts represent the computer basically teleporting her and giving her fake memories. It saves an awful lot of space.
- Mood Whiplash: A four-layered version of it when River tells the Doctor his own name (although it's not until later that we find out what she said). After a pause, he suddenly starts talking about his sonic screwdriver again. Then Anita realises she has two shadows. Then the Doctor points out that Proper Dave has caught up with them.
- More Expendable Than You: River takes out the Doctor to do a Heroic Sacrifice in his place because he has more heroic saving to do and her diary is full.
- My God, What Have I Done?: The Girl has one after she snaps at her father and causes him to vanish. In response, she hurls the remote to the floor and it activates the Library's self-destruct mechanism.
- Nightmare of Normality: As a result of trying to rescue all four thousand visitors by saving them to her database, CAL has accidentally inflicted this trope on herself, living out her fantasies of being an ordinary little girl in a virtual reality environment.
- Ninja Prop: The episode uses Jump Cuts to transition from a scene to the other (for example, the characters in a house talk about taking a stroll in the park, and we jump to the park). Quite an ordinary way of depicting the passing of time in a TV medium, right? Except Donna realizes that she isn't experiencing at all the time between the cuts, only fake memories. This is her first hint she's inside a Lotus-Eater Machine.
- Noodle Incident: Both of these would go on to be resolved by later episodes.
- No Sympathy: The Vashta Nerada didn't really care that Anita was scared, they just wanted to eat.
- Not Now, Kiddo: Doctor tries reassuring Dave that he's got things under control, as Dave repeats, "We should go, Doctor!" When Dave repeats it the fourth time, the Doctor goes Oh, Crap! as he realized Dave died behind him in seconds.
- Oh, Crap!:
- The Doctor, when he finally realizes Other Dave's been eaten, gets more nervous.
- Anita when she realises she has two shadows.
- The Vashta Nerada when they look the Doctor up.
- Only Known by Their Nickname: Donna's virtual-reality husband wasn't really named Lee McAvoy in real life.
- Papa Wolf: Technically the little girl for whom Strackman Lux is willing to go to such lengths to protect is his aunt, but she died as a child and maintained that mental state. It plays out the same.
- Parent-Induced Extended Childhood: Played with; the library's central computer CAL is actually a little girl named Charlotte Abigail Lux. Her father incorporated her into the system in order to save her from a terminal illness, allowing her eternal youth and all the books in the universe to read. For good measure, her family kept her existence a secret in order to prevent her from becoming a freakshow to the rest of the galaxy. As benevolent as this move was, it's implied that CAL isn't happy with it, as her Lotus-Eater Machine features her living an ordinary life on Earth with her father (who has been dead for decades in the real world). In the finale, River Song is uploaded to the system after her Heroic Sacrifice, allowing her to become a surrogate mother of sorts to CAL.
- Le Parkour: In one scene the Doctor essentially follows the Parkour principle of "Getting from point A to point B ASAP" as he runs, jumping over carts and shelves and even just jumping into a hole instead of using the mobile transport platform to save River.
- Percussive Prevention: River punches the Doctor out so she can undertake the Heroic Sacrifice instead.
- Pink Girl, Blue Boy: Josh and Ella's pyjamas. Also, in the playground, Ella's coat and boots are pink and red, while Josh wears a green coat and jeans. Possibly a subtle clue to show that they're not real.
- Platonic Cave: Charlotte is trapped in one, unable to realize that her world is a computer simulation because of the 4,022 uploaded people taking up too much memory space.
- Powered by a Forsaken Child: The Library exists for the sole purpose of keeping CAL occupied, which makes this an inversion. The Library itself is the inversion — there is a child with a terminal, incurable illness, but her family is rich, so her brain is uploaded and she is given a library the size of a planet to keep her entertained. However, when something threatened the people in the Library, they all tried to teleport away at once and ended up getting stored in the computer. This starts causing problems for the child, so in a way the lifeboats are Powered by a Forsaken Child.
- Quotes Fit for a Trailer: The "Next Time" trailer at the end of "Silence in the Library" combines the Doctor asking about CAL, River and the Doctor both saying "Spoilers" and the little girl screaming "No! Don't tell! You mustn't tell!" to create a truly Fourth Wall-leaning clip.
- Rescued from the Underworld: Getting Donna back out of the computer requires some help from someone who knows the truth of the matter.
- Retroactive Preparation: Used by the Doctor to save River Song.
- Self-Destruct Mechanism: The Library has one of these. It starts at twenty minutes. Then it will "crack like an egg".
- Shout-Out: Miss Evangelista's glitched face looks rather like a Picasso painting.
- Shown Their Work: Even for the largest computer ever created in the distant future, 4022 people is an incredibly huge amount of space. One person is 2x10^45 bits of space. That's 2.27x10^31 terabytes according to this Because Science episode.
- Simulated Fantasy, Post-Apocalyptic Reality: It's revealed that the Library's population was saved from the apocalyptic release of the Vashta Nerada by its central computer CAL - "saved" in the sense that she literally saved them to her hard drive, where they could live in a comforting virtual reality scenario while they waited to be rescued. Unfortunately, the Library was officially quarantined afterwards, meaning that nobody has even approached the planet for a hundred years, leaving everyone trapped in the VR neighborhood - including CAL herself thanks to the strain on her memory.
- Smash Cut: There are lots of them while Donna is in the virtual world. They show that the smashes are missing.
- Smug Snake: The Vashta Nerada get rather smug towards the end, when the Doctor informs that he's going to offer them a deal; they let everyone go, and they get their forests to swarm in for all eternity, which they respond to by saying, "these are our forests, they are our meat." The Doctor warns them again, pointing out that they have made the usually lethal mistake of killing someone he likes, and they start extending the shadows towards him. The smugness is very abruptly broken when he tells them who he is and to look him up. The shadows pause, then very rapidly retreat, with a curt and slightly subdued acceptance of the deal as they run.
- Sound-Only Death: If River screams as the energy runs through her, it's drowned out by the energy's noise. Doubles as a Gory Discretion Shot as blinding light obscures her, and later the camera never pulls away from the Doctor as he stares devastated at her body.
- Speech-Impeded Love Interest: Donna's husband stutters. Outside the computer, she takes this to mean she subconsciously wants a husband who can't say anything.
- Spooky Silent Library: Slightly louder since the last episode because so many zombies are talking in broken records.
- Spot the Imposter: The Doctor does this after Anita finds out she has two shadows. Near the end of the episode, he reveals in a Wham Line that he knows Anita is dead because her suit only has one shadow instead of two, so it's actually the Vashta Nerada talking with her voice.
- Stable Time Loop: The sonic screwdriver, many of River Song's mannerisms and rules, including "spoilers!" and the blue diary, she initially got from the Doctor, who in turn got them from her. Another example is opening the TARDIS with a click of the fingers; the Doctor hadn't even thought of doing that until River mentioned it, but she was remembering how he used to do it.
- Staring Down Cthulhu: The "look me up" scene is the Doctor confronting a swarm of living shadows and making them blink. Considering the Doctor's reputation, it's perhaps not surprising that they backed down.
- Stunned Silence: The Doctor's reaction when River whispers his real name into his ear.
- Subverted Catchphrase: One only noticeable in hindsight. In many other River episodes, she and the Doctor have a recurring dialogue of: "I hate you!" and an affectionate "No, you don't." In this episode the Doctor replies to River's "I hate you!" with a dismissive "I know!"
- Swiss-Army Weapon: The Doctor's got his screwdriver, and River's got hers, which has a red setting and dampeners.
- Tempting Fate: Lux says the Doctor Moon will protect CAL and stop the self-destruct. In the next scene, the Girl uses the TV remote to make Doctor Moon vanish.
- Tomato in the Mirror: Cal has a Freak Out when she learns from her nephew that she's a computer reconstruction of a little girl. She accidentally deletes her father and Doctor Moon, which causes her to panic further. It takes River pulling a Heroic Sacrifice to calm down CAL, restore her defaults, and restore everyone who was "saved" and not killed by the Vashta Nerada.
- Too Spicy for Yog-Sothoth: When the Vashta Nerada, a pseudo-Living Shadow conglomeration of creatures thats name translates roughly into "The Shadows that melt the flesh", with good reason, which exist apparently everywhere in the universe, corner the Doctor, he gives the Badass Boast "I'm The Doctor, you're in the biggest library in the universe, look me up" not only does the Vashta Nerada stop for a second, but starts backing off as well!.
- Trauma-Induced Amnesia: Of a sort. CAL was forced to save all of the people who tried to teleport out of the Library to her hard drive when the system overloaded, but this used up so much of her operating memory that she forgot the reality of her situation and her current status as a computer.
- Trust Password: River convinces the Doctor to trust her by telling him his real name.
- Tuckerization: In the virtual reality, Donna's two "children" are called Josh and Ella. Josh is the name of Steven Moffat's son, with Ella being a friend of his.
- The Unreveal: River Song knows the Doctor's real name, but only whispers it to the Doctor. We never hear it in "Forest of the Dead", and still have yet to.
- Victory Through Intimidation: The Doctor has no way to physically stop the Vashta Nerada (or at least, none we know of), so he gets them to back off by threatening them with his reputation."I'm the Doctor, and you're in the biggest library in the universe. Look me up."
- Virtual Ghost: The final fate of River and her crew is to live forever as data inside the Library's hard drive.
- Virtual-Reality Warper: Moon initially appears to be able to fast-forward Donna through her life via jump cut and erase her memories if she happens to notice anything unusual. In reality, Dr. Moon is just a support program for the Library's central computer, CAL; while Moon has a certain degree of influence over things, CAL has full power over the simulation - as evidenced when she has a panic attack and accidentally begins deleting people from the simulation, even deactivating Dr. Moon. Fortunately, once the Doctor saves the day, CAL and Dr. Moon are able to rebuild the simulation so as to provide a comfortable Artificial Afterlife for the now-digitized River Song and her friends.
- Wham Line:
- "BECAUSE SHE'S FAMILY!"
- "You know what? I really liked Anita..."
- "River, you know my name."
- The X of Y: "Forest of the Dead".
- Your Princess Is in Another Castle!: The Doctor sets down River's diary and sonic screwdriver, leaving them behind to turn and walk away with Donna, as River begins a voice-over. It's all set up to make people think the story will end on that note, until the Doctor thinks of a very urgent question.
