Partners in Crime (TV story)

Synopsis
Donna Noble is determined to find the 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 is walking down a street on the way to Adipose Industries, as she is investigating them on their weight-loss drug. The Doctor is doing the same but they fail to see each other as they do different things at the same time. They are in a conference room posing as Health and Safety when a reporter starts asking Miss Foster what this drug does; she fails to tell her and the meeting ends. The Doctor and Donna ask different employees for customer addresses.

Donna goes to a woman named Stacey Campbell's house while the Doctor goes and interviews a man called Roger Davey about his use of the drug. Roger tells the Doctor that his burglar alarm keeps going off at 1:10 AM. While Donna is talking to Stacey, Stacey tells Donna that she has lost a lot of weight and can't wait to dump her boyfriend. Stacey goes to the bathroom and it is at this point where Donna begins to examine the capsule-like pendant. This results in a singular tubby piece of fat coming out of Stacey's body. Donna, oblivious to what is occurring then begins to investigate what is happening up stairs. Miss Foster is alerted that there has been an "unscheduled parthenogenesis" and sends out a squad team to retrieve the new Adipose child. The Doctor is also alerted of the 'birth' via a Y-shaped hand-held device. Miss Foster then incurs "full parthenogenesis" upon Stacey as the Adipose child had been witnessed by her, resulting in her entire body being converted into numerous Adipose, killing her instantly. Donna, who is now up stairs due to the unnerving shrieks emitted by Stacey in her last moments, breaks into her bathroom and as an Adipose waves to her it jumps out the window. Miss Foster senses it via her computer and she scans the CCTV with her henchmen only to find a reporter from earlier called Penny Carter. The Doctor senses what has happened to Stacey and runs up to her house only to find nothing there. He then runs off to the TARDIS. Donna cancels Stacey's cab and goes home only to find her mother nagging at her so she goes off to see her grandfather Wilfred Mott who is gazing at the stars at the allotments. He tells Donna to find the right man as she talks to him about missing the trip with the Doctor. The Doctor is in the TARDIS and talks to himself about the Adipose (He is thinking he has got Martha with him only he realises that he does not).

The next day Donna takes the car to Adipose industries only to be criticized by her mother because she needs the car for going out. Donna hides in the toilets until the end of the business day and the Doctor hides in a closet, to investigate. All day Miss Foster is looking for Penny Carter who is hiding in the same toilets as Donna. Donna thinks that she has been caught but it turns out to be Penny, who is then tied up. Donna follows only to find that the Doctor is also watching Miss Foster. He spots Donna watching through the door and mouths to her and she mouths back. They are both unaware that they are being watched by Miss Foster and everybody in her office. Miss Foster asks her two henchmen to get them and they chase after Donna, but she runs up to the roof. Handily for the Doctor he was on a window cleaner's pulley; he pulls himself up to rescue Donna. As they get in, he locks the roping device with the sonic screwdriver so that he can get down. But to his surprise Miss Foster has a sonic pen with which she sends them down flying as she cuts the rope with it. Donna almost falls but the Doctor climbs up a rope and squeezes into a window. He then goes down a floor to Miss Foster's office, only to find that Penny is locked in there. He opens her window with his screw driver and saves Donna.

Miss Foster then uses a device (possibly another sonic pen) which opens a sliding door to reveal an Inducer, which along with her capsule helps her to begin the birthing process of one million Adipose from her customers' bodies. Meanwhile the Doctor breaks into a secondary Inducer, hidden inside a cupboard, with his Sonic screwdriver. There he manages to temporarily disable the process by unscrewing his capsule and attaching it to a wire connected to the Inducer. While he is doing this Donna tells the Doctor that he looks older. She also asks if he's still on his own; he replies that he had this friend called Martha but he ruined her life but she's fine, he also says that Rose is still missing. Miss Foster notices he has tried to hack into the system and increases the power to double strength on her Inducer. The Doctor realises he can't save them without a second capsule and is really upset, until Donna pulls out the capsule she took from Stacey Campbell's house from her jacket pocket. The Doctor uses this to save the people's lives. Miss Foster's plans have failed but she says that one million Adipose will have to do and calls upon the Nursery Ship to take them home. The Doctor listens to an incoming signal from the Adiposian First Family that identifies Matron Cofelia (Miss Foster's real name) as a criminal for breeding on a Level 5 planet. The Doctor and Donna run onto the rooftop to try and save Matron Cofelia. Donna suggests blowing up the Adipose, but the Doctor replies that they're just children and can't help where they came from. Donna says that Martha must have done him good and he says, with arrogance, that she fancied him. He offers Matron a hand but she refuses just as the tractor beam switches off and she falls to her death; the Adipose leave the planet and zoom off into space.

The Doctor bins the sonic pen and Donna drags him off to the TARDIS. Once there she unpacks her belongings from her car (which is just a few feet from the TARDIS). 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", and says that he is just an alien streak of nothing. The misunderstanding mostly resolved, Donna then takes her car keys and puts them in a bin on Brook street, 30 yards from the corner. She then tells a girl with blonde hair to tell her mother: 'that bin there'; it turns out the girl is Rose Tyler. Donna then returns to the TARDIS, while Rose walks off down the street and disappears. Donna tells the Doctor to materialise two and a half miles "that way" to say goodbye to her Granddad; he cheers her on when they appear just above the hill from which he stargazes.

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. 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 it was decided to bring Donna back, this idea was dropped, although a minor character in the episode (the journalist) was given the name Penny Carter.
 * This episode is broadcast much earlier at a 6.20 timeslot. It is also fifty minutes long rather than forty five, as the TV listings state it is from 6.20 to 7.10.
 * A certain shot shows an army of Adipose in the streets of London, this was extremely complex and took the CGI team (The Mill) more time than most shots used for the series to complete. They used the software called Massive, which was created and used by Weta Digital, 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 Doctor says he's met 'cat people' before, he may be referring to the cat people he met in New Earth and Gridlock, or during Survival.
 * In The Fires of Pompeii the planet Pyrovillia also has gone missing similiar to the Adipose Breeding Planet.Important 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 the earlier slight-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; 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, suggesting that they are an orginization rather than just a treaty (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.

Continuity

 * Donna declined the Doctor's offer to travel with him in DW: The Runaway Bride, but accepted this time to travel with him.
 * Wilfred Mott, Donna's grandfather, appeared in DW: Voyage of the Damned as the newspaper dealer.
 * This is the first episode since DW: Doomsday in which Rose Tyler appeared as a present character.
 * 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 in TW: Fragments.
 * This is the first reference to disappearing bees (which is explained in DW: The Stolen Earth). Although intended as a storyline reference, this is actually a real-life concern.
 * On one of the taxis there is an ATMOS sticker on the windscreen. This will crop up again in DW: The Sontaran Stratagem / The Poison Sky.
 * In DW: Turn Left, sixty million Americans are converted into fat. Adipose Industries had targeted the United States rather than London since it no longer existed, having been destroyed when the Titanic crashed, and the entire South of England was flooded by radiation.
 * Humanoid Catkind are mentioned.
 * A catflap is examined as a method of either ingress or egress for a sneaky alien threat, just as it had been in DW: Rose.
