A Fix with Sontarans (home video)

For the release of the Doctor Who: The Collection — Season 22 blu-ray boxset, a re-edited version of A Fix with Sontarans was included as a bonus feature, differing from the original in several ways; the two minutes of footage of Jimmy Savile from the original were removed as an ethical choice following the controversy surrounding him, and the fourth wall breaking ending that featured Savile was replaced with an all-new CG scene decpiting a fleet of Sontaran ships. Unlike the original, which is an invalid source for writing articles on this Wiki due to the ending, as this edition omits it, the 2022 edition of A Fix with Sontarans is a valid source.

Plot
The Doctor is operating the controls on the TARDIS console, accidentally transporting his former companion Tegan Jovanka on board after he pressed the matter transporter by mistake. Despite her annoyance at being transported from Earth, she reluctantly agrees to help when the Doctor reveals that two Sontarans are on board. The Doctor gets Tegan to help shut off all the sources of power, in the knowledge that the Sontarans have a powerful vitrox bomb with them that requires lots of power to detonate. If he cuts off the supply to the power cable they intend to tap into, he hopes that this will lure them into the TARDIS control room; Tegan points out, however, that they don't have anything to defend themselves with once they arrive, which the Doctor hadn't considered. The Doctor tells her that he'll improvise.

The Doctor then tells her to press the blue button, but, given the vague instruction, she presses the wrong blue button. He scolds her, telling Tegan that she has reactivated the matter transporter. The matter transporter, that seems to be influenced by what the Doctor is thinking, begins to work, transporting someone, not unlike the Doctor, would come and help him and Tegan. He guides Tegan's hand to the correct button and turns down the power, isolating it to control room. The matter transporter finishes, materialising a young human boy. The Doctor and Tegan hide, coming out after a few seconds, though the boy makes them jump by shouting "boo!" The Doctor asks the boy who he is while hiding behind Tegan, and the boy introduces himself as Gareth Jenkins. While Tegan wants to send Gareth back to Earth given the danger, the Doctor tells her it isn't possible due to the Sontarans and their bomb. Gareth offers to help them against the Sontarans, but while the Doctor doubts him, he reluctantly agrees given that the Sontarans will be arriving any minute. He tells Tegan to fetch a box, which she does, despite her indignant protesting.

After Tegan places the box on the floor, the Doctor and Gareth begin to activate a series of controls on the TARDIS control console, and after a short while, the energiser in the console is fully primed, meaning that a trap has been laid for the Sontarans. Just then, the open-skinned Sontarans burst through the doors in a shower of smoke and sparks, and the Doctor, furious, shouts at them for destroying his "beautiful" doors, which weren't even locked. The Turner demands that the Doctor treats Grand Marshal Nathan with respect, which he feigns to agree to. The Doctor, in turn, introduces himself, Tegan, and Gareth; Nathan immediately recognises the identity of Gareth despite his young age, pleased at capturing a bigger prize than he originally anticipated. Nathan instructs the shorter Sontaran to kill Gareth, as they know that Gareth Jenkins led the Earth Defence Force against the Sontarans in their invasion of Earth in 2001, in the Sontarans' future. Having no way to disaude the two Sontarans from killing Gareth, the Doctor tells Gareth to activate the trap that they set up, pressured steam kills them horribly, causing green blood to spew from their mouths, with steam rising from their convulsing bodies, and for their bodies to shrivel up. Tegan and the Doctor congratulate Gareth on killing the duo of Sontarans, and the Doctor asks how Gareth knew where all the TARDIS controls were, he responds: "Well, I've seen you fly the TARDIS on telly." Tegan worriedly tells them to look at the TARDIS scanner turns on, revealing an entire fleet of Sontaran ships outside. The Doctor exclaims, "this was just the beginning."

Story notes

 * When Tegan arrives, the Doctor explains he has regenerated; since Tegan witnessed this before, she is not surprised. She is also shown to be somewhat familiar with the TARDIS controls, in keeping with her earlier appearances.
 * However, Tegan is unfamiliar with Sontarans, which is contradicted by AUDIO: Heroes of Sontar and PROSE: Sontar's Little Helpers, which depict Tegan prior to the events of this story encountering Sontarans.
 * Gareth Jenkins reunited with Colin Baker for the first time since filming at a signing event in January 2013.
 * In 2015, Gareth Jenkins was interviewed by Toby Hadoke for Round 107 of Big Finish's charity podcast series Toby Hadoke's Who's Round. Clinton Greyn also shared his memories of the story in the 234th edition.

Production errors

 * Tegan is wearing a flight attendant's uniform similar to the one she wore in the series, even though she lost her job at the airline sometime between Time-Flight and Arc of Infinity. Though the short story Fixing a Hole, which acted as a sequel, addressed this by having Tegan say she had to call in favours to get back her job.

Continuity

 * The Doctor is a Time Lord. (TV: Spearhead from Space, The Mysterious Planet, et al.)
 * Doctor Who is a television series in the Doctor's universe. (TV: Remembrance of the Daleks, In the Forest of the Night, et al.)
 * Tegan later recalls this adventure in conversation with the Sixth Doctor. (PROSE: Fixing a Hole)

Home media releases
In the wake of widespread allegations of paedophilia against Jimmy Savile, the original cut of A Fix with Sontarans was pulled from any post-2014 DVD release of The Two Doctors ; the 2022 two edition is currently entirely exclusive to the release of Doctor Who: The Collection — Season 22.
