Goodbye, Sarah Jane Smith (TV story)

Goodbye, Sarah Jane Smith was the sixth and final serial of series 4 of The Sarah Jane Adventures. It was written by Clayton Hickman and Gareth Roberts and directed by Joss Agnew. It featured Elisabeth Sladen as Sarah Jane Smith, Tommy Knight as Luke Smith, Daniel Anthony as Clyde Langer, Anjli Mohindra as Rani Chandra, Alexander Armstrong as Mr Smith and John Leeson as K9.

In a sad case of irony, arising from the title and plot, it was the final story of the programme to be broadcast during the life of its star, Elisabeth Sladen. The story introduced a pair of foil characters to Sarah and Mr Smith, Ruby White and Mr White, and dealt with Sarah's quiet fear of growing too old and ill to continue protecting the Earth, becoming purposeless. It also revealed how deeply Luke's departure to Oxford had affected her.

It served as the last story in any media to feature K9 Mark IV for almost a decade, before the robot dog finally returned in 2020's Farewell, Sarah Jane, a story celebrating the life of Elisabeth Sladen.

Synopsis
Sarah has begun developing a form of dementia, and she realises that her ability to defend the Earth is diminishing. She must now hand over the task to surer hands. A seemingly suitable replacement, Ruby White, has arrived on Bannerman Road, but can she be trusted?

Part one
A meteor hurtles towards Earth. Mr Smith redirects it to a safer crash site and says it will contain germ pathogens. The gang hurry to neutralise the germs. The meteorite reads all clear. Then a strange woman appears, claiming to be saving the world. She drives off in a red sports car and Clyde points out that she is doing the same thing as Sarah. Sarah does not look pleased.

They find the woman has just moved in across the street and go to find out who she is. She behaves coldly towards them, telling them to get out of her house. Her name is Ruby White and she sees them as amateurs. She moved to Ealing because of all the alien activity — Trueman, the Bubble Shock! factory, rhinos driving police cars and alien plant life. Sarah decides to stay away from Ruby, but keep her eyes open.

The next day, Gita waves to Sarah on her way home. Sarah says she has to make Luke's tea and then realises he is at university. Clyde and Rani go to check that she is alright. She calls Luke, just two hours after she last spoke to him. She can't remember K9's name. Rani suggests she take a holiday and visit Luke. Mr Smith gives a red alert. A fleet of Dark Horde warriors are heading for Earth. They trace the scan beam and lock onto the attic to neutralise enemy technology. Mr Smith diverts the teleport to an uninhabited area. Sarah gives Clyde a gun and says they must protect the Earth by any means.

An advance party of three warriors lands on Earth. Sarah plans to use a device to overload their sensors. She asks Clyde for the sonic lipstick, but he said she told him to bring the gun (which isn't even charged). Sarah has made a big mistake. Then Ruby arrives and tosses spheres to Rani and Clyde. She uses an artificial intelligence to convince the Dark Horde that they are faced by a stronger version of themselves. Their logical reaction is to flee. Clyde suggests calling the AI "Mr White".

They take Ruby back to the attic, where Mr White gets along well with Mr Smith. Sarah says she'd be glad to have an adult friend. Whilst explaining to Ruby how she became involved with aliens, Sarah forgets the Doctor's name for a moment, something she can't believe she did. She orders Mr Smith to medi-scan her. He tells her there is proof of brain tissue deterioration. Sarah takes this to mean she is too old to continue defending the Earth. Ruby makes friends with Clyde and Rani, who are eager to show off their knowledge of aliens. Sarah feels very left out.

Sarah asks Ruby to take over the duty of protecting the Earth, offering her the house, Mr Smith and Clyde and Rani. Ruby agrees. Sarah goes to leave, not even bothering to tell Luke she is going. She orders Mr Smith to wipe her voice from the command program so she can no longer give him orders. She realises something is wrong and begs Ruby to help her. Instead, Ruby teleports her to a "secret cellar" which houses her stomach. She reveals she is the one making Sarah sick draining her life force. She is a Qetesh, whose race devours peoples' thrills and emotions. She targeted Sarah, who has the most exciting life on Earth. Mr White is making a farewell message for Clyde and Rani so they will believe Sarah has gone because "she" will tell them. Ruby's stomach drains Sarah directly as Ruby gloats about how she will feast on the Earth...

Part two
Ruby explains that rather than stop aliens, she will help them and feed on the excitement and terror that humanity will feel. Back in the attic, Clyde and Rani watch Mr White's faked video of Sarah. Clyde blames Rani for putting the idea of a "holiday" in her head. Mr Smith starts acting strangely. He tries to warn Clyde — "Beware Ruby". Ruby shuts down Mr Smith and teleports Clyde to her spaceship. It was her prison, until she reprogrammed its game console (Mr White). Ruby leaves Clyde in the prison to suffocate. Rani tries to call Clyde and hears a knock at the door. She opens it to find Luke. K9, who is back in Oxford, tracks Clyde's phone to space. Rani goes to place the phone near Mr White so K9 can reset him and free Mr Smith from his influence, as well as rescue Clyde. Clyde leaves a message on his phone for the others to find, then collapses. Rani distracts Ruby who sees through and assaults her, but luckily K9 resets Mr White in time. K9 rescues Clyde and the restored Mr Smith imprisons Ruby in a containment vortex, but she escapes. Clyde and Rani go to rescue Sarah. Ruby corners them in the cellar and threatens to devour them completely.

Luke arrives and gives Ruby a warning to leave Earth. When she refuses, Mr White sends a hologram so everyone on Earth sees a meteor hurtling straight for them. Ruby cannot handle the sudden inrush of emotions and thrills from six billion people. The stomach swells, then shrinks and releases all the energy it took from Sarah back into her. Sarah sends Ruby back to her prison ship, where Ruby swears to get revenge on her. Sarah thanks her team for saving her, knowing she could count on them while Mr Smith and K9 finally seem to have put aside their animosity after working together to defeat Ruby. Luke takes them all out for a treat and Sarah says that although the universe is full of amazing things, they have stiff competition on Earth.

(TV: The Mad Woman in the Attic onward) Mr Smith makes one more jab. (TV: The Man Who Never Was) However, while the two have a rivalry still, they seem to be on better terms after K9 saves Mr Smith from Mr White as Mr Smith calls K9 by name rather than "the dog" and admits he isn't so bad, saying he's "met worse". K9 returns the sentiment.
