The TARDIS takes the Tenth Doctor, Martha and Donna to the planet Messaline. As they emerge from the TARDIS, they are met by human soldiers who force the Doctor to stick his hand into a progenation machine. The Doctor's daughter, whom Donna later names Jenny, emerges from the machine. They are soon confronted by the other occupants of the planet, the Hath. The Hath take Martha hostage. Jenny causes an explosion that traps Martha on the other side of the corridor. Martha tends to an injured Hath and earns their trust. The Doctor and Donna meet with General Cobb, who explains that, initially, the humans were meant to live with the Hath, but a dispute arose over something called "the Source", which Cobb believes has the power to end the war by wiping out the Hath. The Doctor inadvertently reveals the location of the Source to the humans and the Hath. The two sides prepare for battle.

The Doctor confides privately to Donna that he is resistant to Jenny travelling with them because she reminds him too much of everyone who was killed in the Time War. Donna becomes intrigued by a series of numbered plaques that she notices in each room. The Doctor, Donna, and Jenny reach the Source, which is a terraforming device within a colonising spaceship. Donna realises that the plaques represent the dates each part of the building was completed; according to the dates, the ship landed only seven days ago. The humans and Hath have bred so many generations through the progenation machines that their own history has degraded into myth. The Doctor determines the original cause of the conflict was a power vacuum created after the death of the mission commander.

By travelling over the surface with a Hath's help, Martha reunites with the Doctor and Donna near the Source shortly before both armies arrive. The Doctor declares the war to be over and releases the terraforming agent. Cobb tries to shoot the Doctor. Jenny steps in the way and takes a bullet to the chest, and the Doctor holds her as she dies. The Doctor picks up Cobb's gun and holds it to his head, but refuses to shoot him. He declares that the humans and Hath should build their new society based on peace. Martha returns home. Meanwhile, on Messaline, Jenny suddenly revives. She then commandeers a rocket and leaves the planet.

Writing edit

Russell T Davies has stated that this episode "does exactly as it says on the tin".^[3] Jenny's death was originally to take place in what Davies called "a Generic Spaceship Room", but producer Phil Collinson suggested filming the scene at Plantasia botanical garden in Swansea.^[4][5] Having Jenny come back to life at the end of the episode was Steven Moffat's idea.^[3]

Casting edit

Georgia Moffett, who plays Jenny, is the real-life daughter of Fifth Doctor actor Peter Davison and The Hitchhiker's Guide to the Galaxy actress Sandra Dickinson.^[1] David Tennant described the episode by saying "We get to see the Doctor's daughter, played by the Doctor's daughter."^[6] Georgia Moffett had previously auditioned for a role in "The Unicorn and the Wasp" in 2007. Her role as Jenny was not chosen because of her father; it was entirely coincidental, but nevertheless a "great PR coup" for the series.^[3] Moffett previously appeared alongside her father in the Big Finish audio story Red Dawn and drama series Fear, Stress & Anger. In Doctor Who Confidential, Peter Davison stated that, after he finished filming "Time Crash", he said to Moffett "[now] it's your turn".

Tennant and Moffett, who met on the episode, started dating some time after filming the episode, and married on 30 December 2011.

Unofficial figures indicated that "The Doctor's Daughter" was watched by 6.6 million viewers, giving it a 38.4% share of the total television audience. The final consolidated figure was 7.33 million viewers.^[7] While most programmes received lower figures than the previous week, Doctor Who had increased its audience. The top rated programme of the day was still ITV1's Britain's Got Talent, although its audience was down by a million at 8.17 million. Doctor Who was the highest rated programme on BBC1 for the day and had the biggest share of any programme on Saturday. The episode received an Appreciation Index score of 88 (considered "excellent").^[8]

"The Doctor's Daughter" received mixed reviews. David Chater of The Times described it as "A wonderful episode – funny, exciting and strangely moving."^[9] Martin Anderson of Den of Geek! stated that it was "rather good – though badly plot-holed". He noted that it was yet another episode of Doctor Who "undermined by Murray Gold's incessant music". He also described the episode as "quite redolent of Tom Baker-era Who, with plenty of dark and cheap corridors to run down and two under-manned warring factions for the Doctor to bring peace to".^[10] For SFX's Ian Berriman, the running up and down corridors was reminiscent of Lenny Henry's 1985 Doctor Who spoof featured on The Lenny Henry Show. Berriman described the episode as "underwhelming", citing that because one "always suspect[s] she's a redshirt" it is difficult to care for Jenny. Although "reasonably diverting", Berriman argues that budgetary constraints make "the story feel so enclosed" and that the episode's plot, likened to "old-school Trek", seems too similar to that of the Sontaran two-parter immediately prior to this adventure because both involve "militarism" and "cloning".^[11] Newsround's Lizo Mzimba also notes the similarities with "The Sontaran Stratagem" and "The Poison Sky". Mzimba asserts that the episode's "biggest problem" is that it tries "to cram an enormous amount into 45 minutes" with most of the "interesting" and new ideas not getting "the attention they deserve" resulting in the audience not caring about either the human fighters or the Hath and thereby limiting a "sense of danger or menace".^[12]

Mzimba observes that, since her return in "The Sontaran Stratagem", Martha shares little onscreen time with the Doctor therefore reducing the emotional impact of her departure in this episode. He describes Moffett as "superb",^[12] with Berriman calling her "cute as a button".^[11] Berriman praises Tennant's performance,^[11] but Anderson suggests that Tennant shouts too much. Anderson asserts that "Donna's role as the Doctor's conscience is beginning to take shape" describing this as "refreshing" in a companion and noting that "Tate has toned down the grating voice a tad".^[10]
