Forest of the Dead (TV story)

Forest of the Dead was the ninth episode of the fourth series of Doctor Who. It marked the death of River Song.

Synopsis
As the shadows rise, the Doctor forges an alliance with the mysterious River Song. But can anyone stop the Vashta Nerada?

Plot
River Song uses her Sonic blaster to create a hole in the wall - enabling her, the Doctor and the others to escape the shadow-possessed Proper Dave down a corridor.

These events are being watched on TV by the girl. She switches channels and eventually finds a channel showing Donna being taken out of the ambulance on a stretcher. Donna wakes up in an ambulance with no memories of her past life, and is treated in a facility by Doctor Moon. The way time progresses in her virtual world seems to be led by her thoughts; Doctor Moon suggests she walks by the river and she suddenly appears at the river. She occasionally finds this odd, but is reassured by Doctor Moon. Before she knows it, she is married to her ideal man Lee, who has a stammer, and has two children of her own. She is then approached by a hooded figure in a playground, who turns out to be Miss Evangelista. She warns Donna that the world is not real. Donna is stubborn and skeptical of Miss Evangelista's words, although soon, much to her horror, she observes that all the children in the playground are copies of one another. This revelation drives the little girl into hysterics, making her father and Doctor Moon disappear with her TV remote. The Library starts to enter a meltdown, and is set to explode.

Meanwhile, the Doctor squabbles with River Song, but is soon stunned when she whispers something in his ear to prove that he comes to trust her completely (later found out to be his name). However, Anita now has two shadows. They are then forced to flee as the Vashta Nerada suit creature has caught them up again. The Time Lord tries to reason with the Vashta Nerada as it takes over more of the team, and finds out they came as microspores in millions and millions of books and then hatched. Other Dave stays behind, but is then killed by the Vashta Nerada, leaving the Doctor inbetween the two Daves. He escapes and sets off after the other three.

Further ahead, River Song is telling Anita about the Doctor she knows and tells her that in the future the Doctor can open the TARDIS by snapping his fingers. The Doctor overhears this, but then switches his attention back to the present. He then figures out that the library's computer hard drive - CAL - is the key to bringing Donna back, for it has literally 'saved' her and all of the 4022 people in the Library 100 years ago to its hard drive. The team travels to the core of the planet to locate the computer. It transpires that the little girl is in fact the hard drive, and was Strackman Lux's grandfather's youngest daughter, Charlotte Abigail Lux (CAL). She was dying so he made an imaginary world and a Doctor Moon to watch over her and every book ever written for her to enjoy, but the stress of having so many minds integrated into her own is making her overload and destroy the planet.

The Doctor realises that in order to restore the 'saved' people, the Library needs extra memory, so he plans to link himself to the core, even though River Song says it will kill him. He sends River and Lux upstairs to prepare for the restoration. River tells Anita to watch him. Anita asks what the Doctor is going to do, and he says restore everyone and get them away, then leave the world to the Vashta Nerada. When asked if he thinks the Vashta Nerada will take his offer, he reveals Anita has already been consumed by them. When they, using Anita's suit, threaten to consume him and everyone else, he reminds them he is the Doctor, in the biggest Library in the universe, and to look him up. They give him one day and withdraw. River returns to find Anita dead, then knocks the Doctor out to prevent him from sacrificing himself to bring back Donna and the others. The Doctor wakes up, find himself handcuffed to the wall and tries to persuade River to let him do this, and reveals that she had whispered his real name into his ear, which apparently he could only tell someone one time. She links in when the countdown reaches zero and dies, as the Doctor looks on.

Donna and the other saved people return, but she cannot find Lee and thinks that perhaps he didn't exist after all. Lee sees her but his stammer prevents him from calling out to her before he is teleported away.

The Doctor realizes in the nick of time that, knowing River's fate and having years to think of a way to save her, his future self must have given her the sonic screwdriver for a reason. He finds that, like the Data Ghosts, her consciousness has been saved in a neural relay he had hidden in the screwdriver. The Doctor manages to upload River's data ghost into the Library's computer where she is reunited with the rest of her team in the virtual reality with Dr. Moon and Charlotte. With the hard drive repaired by the Doctor Charlotte can give the team a comfotable home. River takes care of Charlotte and Donna and Lee's children, telling them the story of the Doctor. In the real world, the Doctor and Donna take off, but before they do, the Doctor tries out what River told him about being able to open the TARDIS doors with a snap of his fingers and is able to do so.

The Doctor

 * Ironically, the Doctor says "Who are you?" to River Song, a line which is often asked of him.
 * The Doctor learns the fate of River Song, and retains this memory through to their "first" meeting in the future. The future Doctor will adjust his sonic screwdriver in order to preserve Song's consciousness so his younger self will be able to preserve her within Cal.
 * Song appears to have knowledge of Time Lord anatomy, including knowledge of regeneration. She also indicates that destruction of both of the Doctor's hearts in this instance is a circumstance after which he will likely not be able to regenerate. It is later revealed she has Time Lord DNA, suggesting that her knowledge of the process is a part of her.
 * River Song reveals to the Doctor that his future self can open the TARDIS doors with a snap of his fingers, presumably due to the affinity the ship has developed with him. While the Doctor doesn't believe this can be done, he tests it out at the end of the episode and is able to do so. The Eleventh Doctor later does the same thing when inviting Amy Pond to join him in The Eleventh Hour.

Story notes

 * The working title for this story was: River's Run. When BBC Video announced the North American release of the Series 4 DVD box set, this title was used in the episode list and not Forest of the Dead. Also, the Radio Times also used this working title. According to REF: Doctor Who: The Writer's Tale - The Final Chapter, the title was changed not long before broadcast.
 * In River Song's voice over, she mentions the "skies of all the worlds might just turn dark", a possible reference to The Darkness, a story arc element that plays out in the series 4 finale.
 * CAL was also the name of the computer graphics company that created the title sequence used between 1987 and 1989 for the Seventh Doctor's TV adventures. A result of this work was the creation of the first photo-realistic CGI TARDIS, featured in DW: Bad Wolf.
 * In the girl's house, on a drawing on the wall, there is a picture of a blonde haired girl and a wolf. This may be a reference to Rose and Bad Wolf.
 * This is the second episode in this series to have a character (River) share the name of a character from the Joss Whedon show Firefly. The first was Cobb in The Doctor's Daughter.
 * Moffat's recurring theme "everybody lives" returns again in this episode. In the BBC podcast associated with this episode, Moffat and Davies point out that so far in the four major storylines that he has contributed to the series, the only "final" deaths that have occurred have been due to old age (such as Billy Shipton and Kathy Nightingale) or illness (Madame de Pompadour). Moffat consequently promises (in the podcast) that he will kill people off in more dramatic fashion in future stories, proven to be true in The Time of Angels/Flesh and Stone.
 * The concept of downloading human consciousness as data - even after physical death - and the philosophical issues surrounding this is an issue being addressed by futurists in real-life, with scientists such as Ray Kurzweil speculating that technology will allow the uploading of consciousness to computers within a generation in his book, The Age of Spiritual Machines.
 * A recurring theme in this and the preceding episode is "Spoilers". This is a term that was coined in the 1990s by science fiction fandom to address the circulation of information revealing the plots and endings of TV shows and movies. Interestingly, the fourth series of Doctor Who contains several examples of plot twists and cameos that were successfully protected from "spoilers". Other examples of successful spoiler protection include the appearance of Catherine Tate at the end of Doomsday. Examples of plot twists that were not successfully protected from "spoilers" included the return of Rose in Series 4 - spoiled in part by people witnessing the filming - and the regeneration of Christopher Eccleston at the end of Series 1 - spoiled by the BBC publicity office itself.

Myths

 * Following the broadcast of Silence in the Library there was much discussion in the Doctor Who fan community over the identity of River Song, with rampant speculation on various characters whom she might "really" be. The episode ultimately leaves her origin ambiguous, although it does establish several times that this was the first time the Doctor met River, meaning she cannot be a past character.
 * In Planet of the Ood, the Doctor is told his "song may end soon", leading to speculation the "death" of River Song is what is being referred to. Although this is one interpretation, in Planet of the Dead Carmen makes a similar prediction, and The End of Time shows that prediction centred on the end of this incarnation of the Doctor.
 * It has been rumoured that River Song is the Doctor's future wife. A hint at this may be when Mr. Lux said, "squabbling like an old married couple", which was followed by River and the Doctor looking into each other's eyes, and then River revealing that she knows the Doctor's name, which he said he could only tell someone under one specific circumstance. This eventually turned out to be true (The Wedding of River Song)
 * Before the official title was revealed to be 'Forest of the Dead', it was rumoured that the episode's title was 'Saved from the Books'.

Production errors

 * The two times we see the Doctor's sonic screwdriver project the image of Donna, the Doctor's tone of voice is different.
 * Several times when the Doctor handles River's sonic screwdriver, the camera changes do not match up his hand positions on the screwdriver.
 * When Anita gets two shadows after she says "didn't do proper Dave any good" she only has one shadow. When they get away from the swarm she has two shadows again.
 * Shortly after Donna's children are taken to the playground, Ella runs by with a scraped left knee, long before she actually injures herself there.

Continuity

 * The Doctor says that the auto destruct in The Library could 'crack the planet open like an egg'. The Seventh Doctor said the same about what the Imperial Dalek mothership's weapons could do to the Earth (DW: Remembrance of the Daleks).
 * River Song says the Doctor has taken her to the "end of the universe". (The Doctor mentioned in Flesh and Stone that the Crack is "The End of the Universe" This reference may or may not be referring to the opening of the Pandorica.)
 * The question of the Doctor's real name dates back to the earliest days of the series (DW: An Unearthly Child, Silver Nemesis), though in more recent episodes (DW: The Girl in the Fireplace, The Shakespeare Code, The Fires of Pompeii, etc.) the fact his name is a mystery has been amplified. An earlier Moffat-written episode The Girl in the Fireplace, directly addressed this issue when Madame de Pompadour reads the Doctor's mind and discovers that the Doctor's true name is hidden (it is not, however, indicated whether she actually learns his true name). In The Wedding of River Song the first question, which will cause silence to fall across the universe when it is answered on the fields of Trenzalore at the fall of the Eleventh, is simply "Doctor Who?".
 * At the end of this episode, River states that some days "Everybody lives!". This is very similar to what the Doctor says at the end of another of Steven Moffat's episodes, The Doctor Dances ("Everybody lives, Rose! Just this once — everybody lives!! I need more days like this!").
 * The Doctor says to River Song "history can be rewritten" to which Song replies "not one line" a reference to DW: The Aztecs.
 * The Doctor has previously spoken his name in EDA: Vanderdeken's Children and also EDA: Interference.
 * The teleport system is similar to that used in DW: The Ark in Space in that it is limited to three at one time.
 * The squareness gun used by River Song to blast a hole in the wall of the Library is just like the gun used by Jack Harkness when he first met the Doctor. (DW: The Empty Child/The Doctor Dances) (Per Steven Moffat, Doctor Who Confidential: "River Runs Deep", it is intended to be the very same gun. That gun was left behind in the TARDIS when Jack Harkness was teleported out with the Doctor and Rose into the game shows on Satellite Five in Bad Wolf)
 * Although the Doctor has never given away a sonic screwdriver exactly, Liz Shaw has a "door handle" device in Inferno, and Sarah Jane Smith has her sonic lipstick.
 * In Flesh and Stone, River Song states "you, me... handcuffs. Must it always end this way?" This unknowningly references her death within this episode. Her statement's true meaning is unknown, other than the obvious playful flirtation and the apparent propensity of handcuff use surrounding their encounters. Also, the handcuffs used to chain the Doctor appear to be the similar to the ones used in Flesh and Stone, implying River obtained them somehow
 * Just as in DW: The Girl in the Fireplace and Last of the Time Lords the Doctor maintains that he is "always all right" in the wake of a great loss.
 * The Doctor says that having 4,022 minds talking inside one's mind (referring to CAL) is like being him. In DW: The Deadly Assassin, it is first revealed that Time Lord minds are all interconnected through The Matrix.
 * River Song mentions the Crash of the Byzantium (DW: The Time of Angels/Flesh and Stone), an event that had not yet happened from the Doctor's perspective.
