History Recap / DoctorWhoS28E3SchoolReunion

** This gets a CallBack in [[Recap/DoctorWhoS30E4TheSontaranStratagem "The Sontaran Stratagem"]] when the Doctor prefaces his introduction of Donna to Martha with a "''Please'' don't fight." Donna's response? "You wish," before going on to congratulate Martha on her engagement, and derisively refer to the Doctor as "Too skinny for words — you hug him, you get a paper-cut!".
-->'''The Doctor (rolling his eyes):''' Ugh, I'd rather you were fighting...

->''"Oh mate, {{the missus and the ex}}! Welcome to every man's worst nightmare."''

* GrandmaWhatMassiveHotnessYouHave: Sarah Jane, who may have changed over the decades, but most emphatically not for the worse.

Brother Lassar and his brethren enter the kitchen in human form, searching for the Doctor. Lassar mocks K9 when he sees him, but K9 shoots a barrel, spilling the toxic oil over the aliens. Lassar snarls to K9, "You bad dog"; [[TakingYouWithMe the dog replies, "Affirmative."]] The explosion takes out a large chunk of the school. The pupils cheer the school's destruction and hail Kenny as the hero who did it. Sarah weeps over K9's sacrifice as the Doctor comforts her.

* BlatantLies: One of the cafeteria workers gets oil all over herself, and is quickly rushed off into another room. Rose is calmly informed by the head dinner lady that she's fine. Even as the worker starts billowing smoke and screaming.
-->'''Cafeteria worker:''' It's OK... She does that.

** [[ScaryBlackMan Mr. Wagner]] informs a student she's moving up to the top class because Milo's failed him. Milo, as in the student the Doctor was questioning in class at the beginning of the episode, and who isn't seen again...

* {{Flanderization}}: Due to how Russell T. Davies tended to [[LoveInterests write most of the female companions during his run]], Sarah Jane comes off more as a jealous ex than an old friend of the Doctor's, seemingly just to make Rose jealous, for no reason.[[note]]Though Lis Sladen herself said Sarah Jane and the Fourth Doctor "shagged over every square-inch of the TARDIS", so make of that what you will.[[/note]] Mercifully, after the immediate territorial pissing match, the two women get giggly over the Doctor's idiosyncrasies and Sarah Jane is nothing more than platonic with the Doctor forever after.

Before she goes, Sarah admits that she wants to stay, but she needs to find a life of her own without waiting for the Doctor. Mickey, though, insists on going along. With a little prodding from Sarah Jane, the Doctor agrees although Rose is less then enthused. Before leaving, Sarah Jane tells Rose she'll be there for her when she needs her.

* BrickJoke: A brick thrown ''thirty years ago'' finally lands; [[Recap/DoctorWhoS14E2TheHandOfFear when we last saw Sarah Jane]], she suspected the Doctor had left her in the wrong part of Britain. Turns out that, in fact, [[https://www.google.com/maps/dir/Aberdeen,+Royaume-Uni/South+Croydon,+Royaume-Uni/@54.1226831,-6.5527868,866282m/data=!3m2!1e3!4b1!4m13!4m12!1m5!1m1!1s0x4884054c1fd77549:0xe8bb05da5cf4c472!2m2!1d-2.094278!2d57.149717!1m5!1m1!1s0x4875fe1ec08ad8a7:0x912821793bd83c26!2m2!1d-0.098251!2d51.357428?hl=en he had, by 914 kilometres]].

* TheBusCameBack: Sarah Jane Smith has been gone for thirty years.

* {{Flanderization}}: Due to how Russell T. Davies tended to [[LoveInterests write most of the female companions during his run]], Sarah Jane comes off more as a jealous ex than an old friend of the Doctor's, seemingly just to make Rose jealous, for no reason. Mercifully, after the immediate territorial pissing match, the two women get giggly over the Doctor's idiosyncrasies and Sarah Jane is nothing more than platonic with the Doctor forever after.

* GrandmaWhatMassiveHotnessYouHave: Sarah Jane, who basically hasn't changed in thirty years.
** In fact she has. But most emphatically not for the worse.
* GenreSavvy: Sarah Jane gets ''two'' moments of this: One is when she realises (off-screen) that something is going on and needs to get into the school... which she achieves by doing exactly what the Doctor does — ''flattering the bad guy's ego!'' The second time occurs when the screaming begins and she immediately puts two and two together — bad stuff and screaming? Who ''else'' is it going to be?

* TheMissusAndTheEx: TropeNamer, courtesy of Mickey. Sarah Jane is the Doctor's former companion, Rose is the current one. Both of them are in love with the Doctor.

* PoorlyDisguisedPilot: AvertedTrope. It's important to remember in the wake of ''Series/TheSarahJaneAdventures'' that this wasn't a PDP for that show. In fact, Sarah Jane's appearance wasn't supposed to lead to a spinoff, but was more to link New ''Who'' with the old show (to show that it was an extension of the old show, not a new version of it). The fact that the episode was successful and RTD decided to create a Sarah Jane spinoff was just a very happy accident.

Over lunch, he convenes with Rose, who is working as one of the serving ladies (and very much displeased at her undercover job). The conversation establishes that they're here because Mickey tipped them off about suspicious activities going on here, and the Doctor is convinced that the tip is good. Everyone at the school is well-behaved and there is something odd about the chips. Rose eats a few, saying she enjoys them. The conversation is interrupted as the head dinner lady comes over to chide Rose for leaving her post. The Doctor gets her to reveal that the school menu has been designed by Mr. Finch himself to improve concentration and performance. As Rose leaves, the Doctor sees another teacher, Mr. Wagner, approach another student, Melissa. He tells her Milo has failed him, so she is being moved to the top class. He also summons another student, Luke, but not Kenny, who is not allowed to eat the chips and has a packed lunch from home. The Doctor looks up and sees Mr Finch gazing down on the cafeteria floor, watching everything like a hawk.

** The [[ScaryBlackMan scary black teacher]] informs a student she's moving up to the top class because "Milo's failed me." Milo, as in the student the Doctor was questioning in class at the beginning of the episode, and who ''isn't seen again''...
** "Taking an early lunch" indeed.

* StableTimeLoop: It's implied that one might be happening regarding the winning lottery ticket that caused the physics teacher the Doctor replaced to quit.

* AngerBornOfWorry: Sarah Jane's reaction after realizing who the Doctor is after her initial joy is "I thought you died! I waited for you and you didn't come back and I thought you must have died!"

* BrickJoke: A brick thrown ''thirty years ago'' finally lands; [[Recap/DoctorWhoS14E2TheHandOfFear when we last saw Sarah Jane]], she suspected the Doctor had left her in the wrong part of Britain.

* OneSceneWonder: Creator/AnthonyStewartHead as the episode's one-shot villain, Mr Finch, delightfully switching between being a SoftSpokenSadist and ChewingTheScenery as the scene requires, and being an absolutely ''masterful'' ManipulativeBastard, who very nearly tempts the Doctor into joining him with what is either a brilliant sales-pitch born of genuine respect for the Doctor, or superbly playing on his ego. If it wasn't for Sarah-Jane Smith, he would have succeeded.

* GenreSavvy: Sarah Jane gets ''two'' moments of this: One is when she realises (off-screen) that something is going on and needs to get into the school... which she achieves by doing exactly what the Doctor does - ''flattering the bad guys ego!'' The second time occurs when the screaming begins and she immediately puts two and two together - bad stuff and screaming? Who ''else'' is it going to be?

The Doctor suggests that the rats may be food. When they enter Finch's office, they find what that "something" is: 13 large, bat-like creatures hanging from the ceiling, asleep. They back out hurriedly, but as the door shuts, the one that we know of as Mr. Wagner wakes and shrieks. Outside, the Doctor tells the others that when Finch arrived at the school he brought twelve staff members with him, so they've got thirteen giant bats to deal with. He is then about to head back in despite the danger so he can use the TARDIS to analyze the oil sample Rose procured. Sarah tells the Doctor she may have something better: to the Doctor's excitement, in the trunk of her car is an inactive and rusty K9 Mark III, with one of his side panels missing.

Over lunch, he convenes with Rose, who is working as one of the dinner ladies (and very much displeased at her undercover job).

The Doctor looks up and sees Mr Finch gazing down on the cafeteria floor, watching everything like a hawk.

While this is going on, the Doctor is in the staff room speaking to Mr. Parsons, head of the History department, who tells him of the extraordinary knowledge of his students since Finch became headmaster. One of his students gave him the exact height of the walls of Troy in cubits. But there's also been some very strange staffing shifts. The day after Finch arrived, just three months ago, seven teachers came down with flu, and were replaced by new hires of Finch's. Except for the one the Doctor replaced, who somehow won the lottery, despite the fact that she never played (the Doctor is implied to have been behind that one). Mr. Finch brings Sarah into the staff room. When the Doctor sees her, he smiles delightedly at unexpectedly seeing his old friend, but introduces himself as John Smith. Sarah remarks that she once knew a man who went by that name. When she learns "Smith" is a new teacher, she asks if he has noticed anything odd. She has lost none of her inquisitive nature, and the Doctor is elated, although he does not reveal his real identity to her.

The Doctor suggests that the rats may be food. When they enter Finch's office, they find what that "something" is: 13 large, bat-like creatures hanging from the ceiling, asleep. They back out hurriedly, but as the door shuts, one of the creatures (likely the one posing as Mr. Wagner) wakes and shrieks. Outside, the Doctor tells the others that when Finch arrived at the school he brought twelve staff members with him, so they've got thirteen giant bats to deal with. He is then about to head back in despite the danger so he can use the TARDIS to analyze the oil sample Rose procured. Sarah tells the Doctor she may have something better: to the Doctor's excitement, in the trunk of her car is an inactive and rusty K9 Mark III, with one of his side panels missing.

At Deffry Vale High School, the headmaster, Mr Finch, notices a student waiting outside his office. She has a headache, and cannot simply go home because she lives in an orphanage. Mr. Finch offers his sympathies, realizing that [[DoubleEntendre there is no one to miss her]], and invites her into his office; it is nearly time for lunch, after all. The door closes, then there is a flap of wings, and the girl screams.

We see that the Doctor and Rose are undercover at the school. The Doctor is doing so by taking up the job of the physics teacher. He asks a few simple questions. Only an intelligent student called Milo can answer. After a few basic questions, the Doctor advances to higher levels of knowledge, finally asking how to travel faster than light. Milo answers every question without missing a beat.

Over lunch, he convenes with Rose, who is working as one of the serving girls (and very much displeased at her undercover job). The conversation establishes that they're here because Mickey tipped them off about suspicious activities going on here, and the Doctor is convinced that the tip is good. Everyone at the school is well-behaved and there is something odd about the chips. Rose eats a few, saying she enjoys them. The conversation is interrupted as the head dinner lady comes over to chide Rose for leaving her post. The Doctor gets her to reveal that the school menu has been designed by Mr. Finch himself to improve concentration and performance. As Rose leaves, the Doctor sees another teacher, Mr Wagner, approach another student, Melissa. He tells her Milo has failed him, so she is being moved to the top class. He also summons another student, Luke, but not Kenny, who is not allowed to eat the chips. The Doctor looks up and sees Mr Finch gazing down on the cafeteria floor, watching everything like a hawk.

In the kitchen, Rose watches the other kitchen staff, all wearing gloves and face masks, bringing in a large barrel of chip oil. One of the ladies warns them not to spill a drop. She gets a call from Mickey, who wants to check in to mention that he's uncovered reports of massive UFO activity in the area around the school three months ago. However, his investigations are being blocked by something called Torchwood. Rose, in turn, realizes that lines up with something she's heard: the kitchen staff were all replaced three months ago with new personnel, at the same time Finch showed up. The conversation is put on hold when the barrel slips, spilling the oil on one of the staff, who starts to burn. The rest usher her into a side room and shut the blinds. Rose starts to phone for an ambulance, but is told by the head lady not to worry, she is all right, [[BlatantLies even as Rose hears screams and lots of smoke billows out of the side room]]. Rose glances down at the barrel, which is leaking a golden, oily substance.

In the maths classroom, Mr Wagner tells the children at their computers to put on their headphones. The screens flicker on. The monitors display a green, rotating cube with rapidly scrolling, alien-looking symbols and seemingly random text on the right. The children type on their keyboards with incredible speed. Clearly, something is very wrong.

Mr. Finch receives a visit from a journalist, Sarah Jane Smith, who has been assigned to write a profile on him. Finch explains that one of the policy changes he has made is free — but compulsory — school dinners.

While this is going on, the Doctor is in the staff room speaking to Mr. Parsons, head of the History department, who tells him of the extraordinary knowledge of his students since Finch became Headmaster. One of his students has given him the exact height of the walls of Troy in cubits. But there's also been some very strange staffing shifts. The day after Finch arrived, just three months ago, seven teachers came down with flu, and were replaced by new hires of Finch's. Except for the one the Doctor replaced, who somehow won the lottery, despite the fact that she never played (the Doctor is implied to have been the one behind that one). Mr. Finch brings Sarah into the staff room. When the Doctor sees her, he smiles delightedly at unexpectedly seeing his old friend, but introduces himself as John Smith. Sarah remarks that she once knew a man who went by that name. When she learns "Smith" is a new teacher, she asks if he has noticed anything odd. She has lost none of her inquisitive nature, and the Doctor is elated, although he does not reveal his real identity to her.

As the Doctor wanders the halls in a slight nostalgic haze, Kenny goes into the Maths classroom. He is shocked to glimpse a bat-like creature under one of the desks. Noticing him, the creature transforms rapidly into Mr Wagner. Wagner tells Kenny to leave and the boy hastily flees the room.

That night, Sarah Jane Smith breaks into the school to explore, and the Doctor, Rose and Mickey do the same. The Doctor sends Mickey to the maths room and Rose to get a sample of the oil, while he checks the headmaster's office. There are sounds of flapping and the occasional shriek. Winged shadows flit across walls.

Sarah, trying to break into Mr. Finch's office, notices she is being watched. She enters a storeroom — where she finds the TARDIS. Stunned at seeing the ship again, she backs out of the room into the gym, and runs into the Doctor. They exchange pleasantries which are cut short by a piercing scream from the kitchen. They meet Rose along the way. The Doctor introduces the two and Sarah comments on Rose's youth.

The scream turns out to be Mickey, who has opened a cupboard full of shrink-wrapped rats. Sarah suggests the rats are for dissection, suggesting cattily that maybe Rose isn't old enough to have gotten to that point in school, but Rose retorts that rat dissection hasn't been performed in schools for years, making a snide dig at Sarah's age. As they head back to Finch's office, and Sarah and Rose begin to bicker, Mickey laughs and tells the Doctor, "{{The missus and the ex}} — welcome to every man's worst nightmare!"

Not knowing that they are being trailed by Mr Finch and another bat-creature, they go in Sarah's car to a nearby café, where the Doctor repairs K9. Mickey teases Rose about her jealousy, while Sarah asks the Doctor if she did something wrong since he never came back for her after his visit home. In an intense moment, the Doctor tries to brush it off, saying that she was getting on with her life, which Sarah disagrees with, as the hardest thing for her was adjusting back to mundane life after all she had seen.

As they leave the café, Rose is struggling to come to terms with the realization that she's not the first person the Doctor travelled with. She tells the Doctor about her anxiety and fear that he'll abandon her. The Doctor promises [[TemptingFate he will not just leave her]], explaining that he did not go back for Sarah because it would have been too hard: "I don't age. I regenerate. But humans decay, you wither and you die. You can spend the rest of your life with me. But I can't spend the rest of mine with you. I have to live on, alone. That's the curse of the Time Lords." Mr Finch hears the phrase "Time Lords" and sends the other Krillitanes to swoop over and scare them.

The next day they all return to the school. The Doctor sends Rose and Sarah to discover what is inside the computers, and Mickey to stay in the car with K9 as surveillance — a task Mickey compares to being "sent to the back of the class with the safety scissors and glitter". The Doctor himself is going to have a word with Mr Finch.

Working on the computers, Sarah and Rose playfully argue about who has had more experience time travelling, yelling the names of the different monsters they have met. Sarah settles it when she mentions she met the Loch Ness Monster, but they soon realise the argument is pointless and bond by comparing notes on the Doctor (Sarah is very amused to hear from Rose that the Doctor still strokes parts of the TARDIS), bursting into laughter when he enters and confusing him.

Finch tells the other Krillitanes that they are moving to the final phase. The school will be sealed and they will become gods. Even though it is break time, the intercom calls all pupils to class and the staff to the staff room. All the pupils appear strangely happy that the break has ended early, except Kenny, who hesitates, but eventually follows the others inside. The Krillitanes begin their plans by devouring the rest of the staff.

In the maths room, the Doctor finds the computers fixed with a deadlock seal which the sonic screwdriver cannot breach. Finch seals all of the school's exits while Mr. Wagner activates the computer program, which the children begin working on again. Kenny cannot get out of the school, but he attracts Mickey's attention. Mickey reactivates K9, asking it if it has some way to get through the locked doors in the school. K9 reminds him they are in a car. It takes Mickey a few minutes to process that K9 is suggesting [[CarFu he break down the glass by using the car as a battering ram]].

Mickey and Kenny rush to the pupils. Finch shrieks, summoning the other Krillitanes, who transform into their bat-forms. Mickey and Kenny meet up with the others and run into the cafeteria, chased by the Krillitanes. Finch tells his brothers he wants the Doctor alive, but to eat the others.

As the Krillitanes attack, K9 shoots down one of them with its blaster. The Doctor tells K9 to hold them off while they retreat. However, K9's battery is failing and Lassar tells the Krillitanes to ignore [[BuffySpeak the shooty dog thing]] and get the others.

So Mickey has to unplug the computers and gets the children out of the school. In the kitchens, the Doctor finds the barrels of oil are deadlock sealed. While the others flee, the Doctor and K9 stay behind. K9 tells the Doctor that the barrels will not withstand a direct hit from his laser, but as his batteries are weak, he has to remain. The Doctor protests, knowing that K9 will be caught in the explosion, but the dog replies there is no alternative. Sadly, the Doctor bids his old friend goodbye, calls him a good dog and exits the building. The Doctor takes Sarah's hand and while she asks about K9, drags her away from the school.

Brother Lassar and his brethren enter the kitchen in human form, searching for the Doctor. Lassar mocks K9 when he sees him, but K9 shoots a barrel, spilling the toxic oil over the aliens. Lassar snarls to K9, "You bad dog"; [[TakingYouWithMe the dog replies, "Affirmative." The explosion takes out a large chunk of the school]]. The pupils cheer the school's destruction and hail Kenny as the hero who did it. Sarah weeps over K9's sacrifice as the Doctor comforts her.

Later, Sarah enters the TARDIS in a park. The Doctor suggests that Sarah join them, but Sarah declines, saying it is time she found a life of her own. Mickey asks if he may join them in the TARDIS; he wants more than just to be their 'tin dog' and is ready to see the universe. The Doctor agrees with a little prodding, although Rose does not look pleased.

* BrickJoke: A brick thrown ''thirty years ago'' finally lands; [[Recap/DoctorWhoS14E2TheHandOfFear when we last saw Sarah Jane,]] she suspected the Doctor had left her in the wrong part of Britain. Turns out that, in fact, [[http://goo.gl/maps/nhHmv he had.]]

* CanNotSpitItOut:

* CreativeSterility: The Krillitanes require the human children to crack the paradigm because it requires ''imagination''.

* {{Flanderization}}: Due to how Russell T. Davies tended to [[LoveInterests write most of the female companions during his run,]] Sarah Jane comes off more as a jealous ex than an old friend of the Doctor's, seemingly just to make Rose jealous, for no reason. Mercifully, after the immediate territorial pissing match, the two women get giggly over the Doctor's idiosyncrasies and Sarah Jane is nothing more than platonic with the Doctor forever after.

* ScaryBlackMan: Mr. Wagner, one of the Krillitane teachers. [[MorphicResonance Even his true Krillitane form is darker than the others]].

So there's a certain [[TheGoodOldBritishComp Perfectly Ordinary Comprehensive]] whose Perfectly Ordinary Students are absolutely ''whomping'' the competition in the school ratings, with enough time left over in the school day to calculate pi to infinity, invent time travel, etc. They're led by new headmaster Creator/AnthonyStewartHead, whose hobbies include looking ObviouslyEvil, [[EvilIsHammy cackling maniacally]], ChewingTheScenery and [[ChildEater chewing on the kids.]]

Sensing high weirdness afoot, the Doctor has gone undercover as a Perfectly Ordinary Substitute Physics Teacher, dragging Rose along to serve as a [[RunningGag Perfectly Ordinary]] Dinner Lady. Rose is a bit miffed that she pulled kitchen duty, but consoles herself with the happy thought of all the chips she can eat. In fact — childhood obesity epidemic be damned — at this P.O.C., school lunches containing delicious chips (French fries in North America) are not only ''free'', but also ''mandatory''.

Somebody ''else's'' weirdness detector has pinged, too: IntrepidReporter Sarah Jane Smith (Creator/ElisabethSladen), companion to the Third and Fourth Doctors, has done what she does best — stuck her nose in exactly where the bad guy ''does not want her to stick her nose'', and turned up at the P.O.C. herself to see what's afoot. It's been thirty-three years since she left the Doctor in her timeline, at least several hundred years (and six[[note]]actually, seven, but we won't see that for another six years![[/note]] regenerations) in his — she is, in case you're wondering, [[GrandmaWhatMassiveHotnessYouHave even more beautiful than she already was]]. He recognizes her — and has a very loud internal squee-fest — but doesn't give himself away, only to come clean when Sarah Jane sneaks into the school at night and finds where he's parked the TARDIS. Here the picture [[SandInMyEyes goes all swimmy and blurry for some reason]].

By the time it clears up again, the Doctor has provisionally identified the cafeteria's chips as the source of the kids' mysterious intelligence. K9 (pulled out of Sarah Jane's car boot, and fixed by the Doctor) identifies the frying oil as "Krillitane Oil", which identifies the baddies as Krillitanes, a bunch of nefarious shapeshifters.

So, OK, villain identified — but what's up with making the kids smarter? Why, so they can solve the Skasis Paradigm, of course! The Skasis Paradigm is a grand unified theory of everything that can rebuild the universe and space and time. The Doctor is eye-rollingly annoyed at yet ''another'' group of beings who want to take over the universe and remake it in their image... but then the head Krillitane surprises the Doctor by offering ''him'' the top job.

Also, Sarah Jane tells the Doctor that she spent the last few decades waiting for him, unable to fall in love again, unable to forget him, unable to trust and unable to live happily as a normal human. The Doctor mumbles something almost resembling an excuse as Rose looks on in horror at what apparently awaits her. Noticing what the Doctor now means to Rose, Sarah Jane gives Rose some pointers on having "a relationship" with the Doctor, and the two bond after some initial awkwardness. Meanwhile, Mickey gets acquainted with K9 and realizes that he's not much more than TheTeam's "tin dog".

With the VillainOfTheWeek appropriately vanquished by K9, having blown up the Krillitane oil and a portion of the school as well as himself, the Doctor prepares to once again make his departure without so much as a proper goodbye. Sarah Jane isn't having any, and finally gets the goodbye for which she's been waiting three decades.

* ScaryBlackMan: One of the Krillitanes poses as one of these. Notably, [[MorphicResonance its true form is darker than the others]].

* BrickJoke: A brick thrown thirty years ago finally lands; when we last saw Sarah Jane, she suspected the Doctor had left her in the wrong part of Britain. Turns out that, in fact, [[http://goo.gl/maps/nhHmv he had.]]

* ManipulativeBastard: Mr. Finch nearly talks the Doctor into joining him with just a few lines of temptation, almost succeeding in doing the same to [[TheHeart Sarah Jane]]. She, however, snaps out of it and [[CrowningMomentOfAwesome snaps the Doctor out of it too]].

* TeachersOutOfSchool: Subverted. When main characters are sneaking around a suspicious school at night, Rose says that she used to think that teachers sleep at school. A moment later...

* ScrewLearningIHavePhlebotinum: The Krillitane oil doesn't ''just'' make the kids smarter, it also dumps a load of knowledge into their heads, such as how to travel through time. It's also possible that those computers they are mesmerized by are teaching them.

* RememberWhenYouBlewUpASun: Sarah Jane Smith and Rose trying to outdo each other with their past adventures. Sarah Jane wins when she points out she's met...

* LongNeck: The Doctor mentions that the Krillitanes used to have extremely long necks, but due to the fact they constantly take on other race's traits, they now look like giant bats.

* HeroicBSOD: Mickey upon realising that he's their "tin dog".
