Partners in Crime (TV story)

Partners in Crime was the first episode of the fourth series of Doctor Who. It marked the reappearance of Catherine Tate as new regular companion Donna Noble. It also saw Sylvia Noble and Wilfred Mott return, as Donna's family. Donna's father Geoff Noble, however, was implied to have died offscreen, following the sudden passing of actor Howard Attfield. Importantly, Rose Tyler made a cameo appearance, heralding her eventual return later in the season.

This episode began the "Missing Planets Arc", with it being mentioned that Adipose 3 had been lost. As a trick to the viewers, this was lamp-shaded by Matron Cofelia mistakenly believing the planet had been lost through political means, instead of it vanishing.

As shown in the future story Turn Left, if the Doctor hadn't been around to prevent the Titanic from crashing into London, the Adipose would have chosen America instead. Worse, without anyone to prevent it, hundreds of people would have died.

Synopsis
Donna Noble is determined to find the Tenth Doctor again — even if it means braving the villainous Miss Foster. But when the alien threat escalates out of control, can Donna find her Time Lord before the march of the Adipose begins at last?

Plot
Donna Noble, wearing a business suit, walks down a street on the way to Adipose Industries, as she is investigating them on their new weight-loss drug. Unknown to her, the Tenth Doctor is there for the exact same purpose. Both enter the Adipose offices through different entrances, and pass themselves off as employees of "Health and Safety".

Both the Doctor and Donna then crash a press conference held by Adipose Industries company manager Miss Foster, Donna sitting with the journalists and the Doctor watching from the projection booth. A science reporter, Penny Carter of The Observer, asks what this drug does; Miss Foster gives them a lecture on the science of the pill, and the meeting ends. The Doctor and Donna ask different employees for customer addresses; Donna also takes a pill-shaped golden pendant — a free gift that comes with the pills. Throughout their time at Adipose, the Doctor and Donna have multiple near-misses.

That night, Donna goes to the house of a woman named Stacy Campbell, who is preparing to go out on a date to dump her boyfriend now that her weight is going down so nicely — "I can do better than him now!" Meanwhile, the Doctor interviews another valued customer, Roger Davey, about his use of the drug. Roger tells the Doctor that he knows he's lost a kilo of weight every night by 1:10 AM — that's when he's always woken up by his burglar alarm. The Doctor deduces that this is because of his cat flap. Not only does it let things in, it lets them out too. As the Adipose slogan goes, "The fat just walks away..." Stacy goes to the bathroom, and Donna begins fiddling with her pendant; the result is that a humanoid cute and tubby piece of fat forces itself out of Stacy's body. Donna, oblivious to what is occurring, then begins to investigate what's going on upstairs. Miss Foster is alerted that there has been an "unscheduled parthenogenesis", and sends out a squad team to retrieve the new Adipose children. The Doctor is also alerted of the "birth" via a Y-shaped hand-held device and runs off down the street to track it. Once Stacy witnesses the Adipose child, Miss Foster activates "full parthenogenesis", and Stacy's entire body is converted into numerous Adipose, leaving nothing but her clothing behind.

Donna, who is now upstairs due to Stacy's screams, breaks into her bathroom just in time to see an Adipose waving to her as it jumps out the window. The Adipose Industries retrieval team scoops up the new Adipose and zooms off in their van, just missed by both the Doctor and Donna — who both give up, and head off in different directions, unaware they are only a few feet away from each other. Miss Foster goes through her CCTV records with her henchmen to find out just who "borrowed" a pendant, and spots her.

Donna cancels Stacy's cab, and goes home, only to find her mother nagging at her about her unemployment. Donna sits at the table, ignoring her, as she tries to get over what she saw. She then goes to see her grandfather Wilfred Mott, who is up at the allotments stargazing. He says she looks like he's drifting, but she replies she's waiting for the right man — the Doctor. She says, "I met him just once...and then I let him fly away." When Wilf urges her to look for him, Donna explains she has — but that he is nowhere. She asks him to keep an eye out for a certain blue box in the sky, and give her a shout if he finds it.

Back in the TARDIS, the Doctor is examining his readings, talking to himself for a moment before remembering that Martha Jones has gone. He stands there in silence.

The next day, despite protests from her mother, Donna takes the car to Adipose Industries, parking in an alleyway nearby. Shortly thereafter, the TARDIS materialises immediately behind it. The Doctor and Donna hide in the building until after hours: the Doctor in a caretaker's cupboard, and Donna in the women's bathroom. Donna even goes so far to conceal herself as to pretend she is in church when her mother calls. Miss Foster suddenly stalks into the toilets searching for the thief — and, much to Donna's surprise and relief, instead pulls out Penny Carter.

Penny accuses Miss Foster of faking her results. As Penny is dragged to Miss Foster's office by her guards, Donna follows, peeking through the office door. The Doctor zips to the roof, fiddles with a window-cleaning crane and drops down to the office window. He watches the same event from the other side of the room. Unable to quite see what's going on, both pop their heads up — only to spot each other. They mouth frantic questions to each other while Donna does her best to mime her answers, all the while unaware that they are being watched by Miss Foster and everybody in her office. "Are we interrupting you?"

Donna runs, while the Doctor locks the door with his sonic screwdriver and raises his window-cleaning cradle to the roof, before racing to the stairs. The pair finally meet, but have to keep running and head back to the window-cleaning cradle to lower themselves down for a quick getaway. Before that, though, Donna explains how she went about searching for the Doctor. "'Cause I thought, "How do you find the Doctor?" And then I just thought, "Look for trouble, and then he'll turn up." So I looked everywhere — you name it. UFO sightings, crop circles, sea monsters — I looked, I found them all. Like that stuff about the bees disappearing, I thought, "I bet he's connected." 'Cause the thing is, Doctor, I believe it all now. You opened my eyes to all those amazing things out there. I believe them all..."

However, even though the Doctor locks the pulley with his sonic screwdriver, Miss Foster has a sonic device of her own. She uses her sonic pen to cut one side of the supporting ropes, making Donna fall out and hanging to the broke rope. Before Miss Foster can cut the other one, the Doctor uses his sonic to knock the pen out of her hand and into his; he uses it to open a window in below Donna and swings Donna inside before following after her. Intrigued someone with advanced technology has appeared, Miss Foster heads back in with her guards to confront the Doctor.

Inside, the Doctor and Donna have arrived back in Miss Foster's office via the window. Out of breath from her screaming, Donna asks if she's right in thinking it's always like this with him around. The Doctor confirms with a smile and tells her it's time to run again. Donna rushes out as Penny, yells for answers; the Doctor tells her that as a reporter, she should just invent a story, which is what people in her profession are good at. He unties her via the sonic, and runs out. However, Penny wastes the chance to flee by searching the office for evidence and is once more caught by Miss Foster and her guards. They tie her up again.

Miss Foster, with her guards, finally catches up with the Doctor and Donna in the main office; she notes that the Doctor must be an off-worlder due to his possession of sonic technology. The Doctor takes out the sonic pen he confiscated, noting that the design is sleeker than his sonic screwdriver. He asks for her real name, learning she is Matron Cofelia of the Five-Straighten Classabindi Nursery Fleet, Intergalactic Class, who has been hired by the Adiposian First Family to breed the next generation of the species from humans following the loss of their breeding planet. Donna wonders how losing a planet is even possible, but Cofelia dismisses it as politics she's not interested in. Cofelia ignores both Donna's protests about Stacy Campbell's death (which she passes off as necessary to keep her presence secret; she does feel bad that using an entire person's matter makes the Adipose born from them a little ill) and the Doctor's that seeding a Level 5 planet is against galactic law.

The Doctor decides to make a last request: does she know what happens if you use two sonic devices against each other? Cofelia hasn't a clue; "Neither do I. Let's find out, shall we?" the Doctor smirks, pointing his sonic and her pen at each other and turning them on. The result is a painful sonic feedback, which stuns Cofelia and her guards. The Doctor grabs Donna's arm and pulls her away. Seeing that she cannot trap the Doctor, Cofelia fears that he might have alerted the Shadow Proclamation of her illegal actions; she decides to call the Adipose to collect the children that have been born already. Seeing that keeping her cover will not last, Cofelia activate the inducer - they're going into premature labour. Down in the basement, the Doctor and Donna head into the cupboard where he hid all day, which has a secondary inducer hidden in the back. He quickly uses the fact that Miss Foster had wired the building to stun her guards. Donna then admits she was a fool to turn down the Doctor's original offer to travel with him, and asks if she can still come. Back in her office, Miss Foster activates the main inducer, which sends a signal to the free pendants that will trigger the Adipose birthing process in the company's one million customers, converting fat, bones and internal organs... and kill the hosts in the process. In a London wine bar, Sylvia Noble is having a girls' night out; one of them, Suzette Chambers, is an Adipose customer and "host". Adipose start popping out of her, as well as out of Roger Davey back at his home. The Doctor manages to temporarily disable the process by unscrewing his Adipose capsule and attaching it to his inducer, but Miss Foster doubles the power. The Doctor begins to panic as he finds himself unable to stop the imminent deaths of a million people, but Donna offers him just what he needs: a second capsule, to block the increased signal.

The second capsule overloads the system, and the Adipose clients return to normal; but ten thousand Adipose have now been born, and are now making their way to Adipose Industries, causing traffic chaos throughout London. The ten thousand will have to do; the nursery is coming. As a benefit, now that the truth about the Adipose weight loss program has been revealed, it's highly unlikely that humanity will welcome the Adipose back to Earth; given that the spark of life could kill/convert them into Adipose.

A gigantic nursery ship arrives over London to collect the babies; while Sylvia gawps at it, Wilfred — the one who's always believed in extraterrestrial life — has his back turned towards his telescope in the other direction and his headphones on, and misses the whole thing. As it arrives, so does a signal from the Adiposian First Family, which the Doctor listens to via the secondary inducer; he suddenly realises that it's no longer the humans, but Miss Foster who is now in serious trouble.

The Doctor and Donna run onto the rooftop to watch several levitation beams carry the Adipose babies up to the ship. Having already seen firsthand what the Doctor can do to even children who he feels are a threat (the Racnoss children), she asks if he plans to blow the Adipose up too, but the Doctor refuses to harm them, as they're just children; they can't help where they came from. Donna openly notes that that is a marked difference from the last time they were in that situation; Martha's time with him seems to have changed him for the better. Smugly, the Doctor notes Martha fancied him; "Mad Martha that one; blind Martha; charity Martha." Donna jokes back to him. A child sees them as it ascends, waving at them. They wave back as the Doctor admits that as a weight loss plan, the Adipose birthing has its merits. They see Cofelia in another beam on her way up to the nursery ship. The Doctor pleads with her to get over to the roof; the Adiposian First Family is aware that their actions are illegal, which means they need to get rid of their accomplice. Cofelia dismisses the threat because she's the nanny - but the Doctor remains worried, exclaiming, "Exactly! Mum and Dad have got the kids now - they don't need the nanny anymore!" At that moment, the levitation beam carrying Miss Foster is switched off, and Miss Foster, with just enough time to realise her fate, falls to her death as the Doctor comforts a terrified Donna. Immediately afterwards, the nursery ship leaves Earth.

Back on the street the Doctor bins the sonic pen as Penny — tied again to her chair — flees the building, unable to cope with what's been happening; comically running off still tied up, she yells that the two of them mad. Donna points out, "Some people just can't take it." Donna promptly drags the Doctor off to the TARDIS — and is delighted to realise he parked just a few feet from her car; it's just like destiny!

She promptly starts hauling a ridiculous amount of luggage out of the car boot and shoving it into the Doctor's arms, saying she's been ready to go for ages. The Doctor warns that it is a hard life but accepts her, saying that he just wants a mate. She misunderstands this to mean that he wants "to mate", saying he's just a "long streak of nothing" and exclaiming, "Well, you're not mating with me, sunshine!" The misunderstanding (mostly) resolved, Donna then calls her mum to say she's put the car keys in a certain bin for her to collect before asking a blonde girl to tell her mother, "That bin there". While Donna returns to the TARDIS, the girl, a sad-looking Rose Tyler, walks off down the street and disappears into thin air...

For her first trip, Donna tells the Doctor she wants to go "two and a half miles, that way." Back at the allotments, Wilf is still puttering about when he spots a certain blue box flying overhead. After first yelling for Donna, he takes a closer look through his telescope, and realises she's in the blue box, waving to him from the doorway — and so is the Doctor! He starts whooping and dancing around in delight as the TARDIS spins away into space, happy she found what she was after: "Go on, girl! Go on, get out there!"

Story notes

 * This episode is dedicated to Howard Attfield, who passed away shortly after filming scenes for this episode reprising the role of Donna's father, Geoff Noble. As Geoff was to have been a recurring character in the season, the producers chose to remove Attfield's scenes and bring back Bernard Cribbins to play Wilfred Mott, the character he played in Voyage of the Damned; the character was retconned to become Donna's grandfather and renamed Wilf (although he was unnamed on screen, the character was called "Stan" in the scripts for Voyage of the Damned). Attfield's scenes were preserved and included on the subsequent Series 4 DVD release.
 * According to his memoir The Writer's Tale, Russell T Davies originally planned to introduce a new companion named Penny Carter in this episode, who he describes as 30-something, recently jilted by a boyfriend, and strong-willed in the vein of Donna Noble. When Catherine Tate became interested in reprising her role as Donna this idea was dropped, although a minor character in the episode (the journalist) was given the name Penny Carter.
 * This episode was broadcast at the earlier timeslot of 6.20. TV listings gave it a fifty minutes time slot rather than forty five, stating it to be shown from 6.20 to 7.10. The actual episode clocks in at just under 49 minutes.
 * A certain shot shows an army of Adipose in the streets of London. This was extremely complex and took the series' CGI team (The Mill) more time than most shots used for the series to complete. They used the software called, which was created and used by , who created all CGI for the Lord of the Rings film trilogy.
 * A scene was shown the day before airing on GMTV showing the Doctor and Donna Noble on a suspended window washing platform breaking in while Miss Foster cuts the cable with her sonic pen.
 * Pointing the functioning ends of a sonic screwdriver and a sonic pen at one another (or, as the Doctor put it, "two identical sonic devices") creates a sonic feedback in the surrounding area.
 * The planet Adipose 3 is the first of the missing planets mentioned in this series. The mystery is solved in The Stolen Earth.
 * The scene with Rose was actually shot along with her scenes in Turn Left. It was removed from the episode when it was shown to the media. According to an interview in Doctor Who Magazine #396, the positive reaction to Piper's surprise cameo (which was successfully telecast without any pre-broadcast revelation in the media thanks to this sleight-of-hand) led Davies to add a third surprise appearance by Rose to The Poison Sky, in addition to one already planned and filmed for Midnight (the Midnight footage was reused). Rose's return wasn't a complete surprise, however; besides media coverage of her return, a clip of Rose from Turn Left had also been included in the official Series 4 theatrical trailer several weeks earlier.
 * Miss Foster mentions the Doctor warning the Shadow Proclamation about her illegal activities, suggesting that they are an organisation rather than just a treaty; this was confirmed in The Stolen Earth.
 * The window cleaner cradle scene was intended for use in Smith and Jones but was cut and used here instead. In the first draft, the initial confrontation between the Doctor, Donna and Miss Foster was to have happened in the cradle, but budgetary and logistics problems meant the scene was moved to the sales cubicles area (and the Doctor's "sonic screwdriver plus sonic pen equals massive sonic feedback" diversion added).
 * The Adipose developed from Russell T Davies' idea that alien genetics were hidden in doses of a Botox-like drug, resulting in the people injected being overwhelmed by the genetic code and transforming into aliens; in his Writer's Tale he describes it as "Ladies Who Lunch/Lurch" (one of his cartoons included in the book shows his take on the idea).
 * This was the last episode until the 50th anniversary special not to include a pre-credits sequence.
 * Additional material for the episode (namely the reshoots featuring Bernard Cribbins in place of Howard Attfield, and Rose's cameo at the end) was directed, uncredited, by Graeme Harper, according to the DVD commentary.
 * This is the first reference to disappearing bees (which is explained in The Stolen Earth). Although intended as a storyline reference, this is actually.

Production errors

 * In every scene Miss Foster's guards change position.
 * When the Doctor and Donna are in the cradle, Miss Foster is seen cutting the cable on the right (the Doctor's side). However, the cable on the left (Donna's side) is the one that snaps. This mistake is confirmed a few moments later; when Miss Foster says, "Now for the other one", she moves over to the cable on the left, which has clearly already snapped. This is realised in the episode commentary.
 * When the Doctor is erecting a sonic cage around the cradle controls, he puts the sonic screwdriver in his mouth, with the emitter facing to his left. When he turns to look at Donna briefly and takes it out of his mouth, the emitter is facing to his right.
 * At 17.21 the numberplate of the Noble family's car is YD55VHG. However, when Donna collects her bags from the car at 43.01 it has the numberplate LN54VKR.
 * In the scene with the Doctor and Donna outside the TARDIS, the rain in the alleyway stops and starts every time the angle changes. The production team had some difficulty filming this sequence due to both the weather (filming had to be rescheduled due to rain) and then a very noisy nightclub nearby, as related by Russell T Davies in The Writer's Tale 
 * Miss Foster places an Adipose on her desk, but in the next shot, it's gone.
 * The electrocuted guards disappear.
 * Stacy Campbell's name is clearly visible onscreen among other clients of Adipose Industries, but the end credits refer to her as "Stacey Harris".

Continuity

 * Donna and the Doctor refer to many instances the last time they encountered each other, including the Doctor drowning the Racnoss children. Donna declined the Doctor's offer to travel with him then, but regrets the decision and accepts this time. (TV: The Runaway Bride)
 * The Doctor mentions how Rose Tyler is still lost, (TV: Doomsday) and how his most recent companion Martha Jones suffered while adventuring with him. (TV: Last of the Time Lords)
 * The Doctor and Donna constantly missing each other by a fraction resembles the First Doctor and Vicki constantly missing Barbara Wright and Ian Chesterton while in Rome. (TV: The Romans)
 * Rose Tyler appears, briefly returning from the parallel universe in which she was locked. (TV: Doomsday)
 * The effect of pointing the sonic pen and sonic screwdriver (or, as the Doctor put it, "two identical sonic devices") at one another is remarkably similar to an effect of a sonic device used by Toshiko Sato. (TV: Fragments) This trick was also done by the Fourth Doctor and the Eighth Doctor to enter The Master's TARDIS when trapped in a pocket dimension (AUDIO: The Light at the End)
 * Reference is made to disappearing bees and a missing planet. (TV: The Stolen Earth)
 * One of the taxis has an ATMOS sticker on the windscreen. (TV: The Sontaran Stratagem / The Poison Sky)
 * In a parallel world, sixty million Americans were converted into fat. Adipose Industries had targeted the United States rather than London, as the city had been destroyed and the entire South of England flooded by radiation when the Titanic crashed. (TV: Turn Left)
 * Roger Davey says he is not a cat person, which makes the Doctor reflect on his past encounters with "cat people". (PROSE: Fairy Tale of New New York, TV: New Earth, Gridlock)
 * A catflap is examined as a method of either entry or exit for an alien threat. (TV: Rose)
 * The Shadow Proclamation is mentioned. (TV: Rose, The Christmas Invasion, Fear Her) The Doctor will later take Donna to meet them. (TV: The Stolen Earth)
 * Donna refers to the Titanic replica over Buckingham Palace, saying it must have been a hoax. (TV: Voyage of the Damned)
 * Donna and the Doctor's mimed reunion echoes a similar situation involving the Third Doctor and Jo Grant. (TV: The Sea Devils)
