Okay here is part 2 of School Reunion, now the plan is to do this then do The Caretaker, Army of Ghosts, Doomsday, then have The Snowmen up on Christmas, so hopefully I can do that. Anyway enjoy this and if there are any mistakes tell me so I can fix them, also if you want a certain episode tell me and I will see if I can figure out when I can do that episode.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

We had decided to investigate the school later at night so we had now changed into more appropriate cloths, me I was in skinny jeans, as well as running shoes and a dark blue shirt with a pocket on the side that was really just there for decoration and had my hair back in a hair tie. Rose was now wearing jeans and a shirt with a dark blue hoodie with what I think was the school crest on the side of it, the Doctor had also put on his trench coat and we were now breaking into the school.

"Oh, it's weird seeing school at night. It just feels wrong. When I was a kid, I used to think all the teachers slept in school." Rose tells us grinning and Mickey besides me looking rather trying to stay cool and not freak out.

"All right, team." the Doctor says then makes the 'I don't like that' face. "Oh, I hate people who say team. Er, gang. Er, comrades. Anyway, Rose, go to the kitchen. Get a sample of that oil." the Doctor says gesturing for Rose to do that then turns to Mickey. "Mickey, the new staff are all Maths teachers. Go and check out the Maths department. Harmony and I are going to look in Finch's office. Be back here in ten minutes." the Doctor says and pulls me up the stair with him.

"And be careful not to make too much noise" I tell them as I get pulled by the Doctor.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

Sarah Jane had just come out of the storeroom at which the Tardis was in when me and the Doctor got there.

"Hello, Sarah Jane." the Doctor said.

"It's you. Oh, Doctor Oh, my God, it's you, isn't it. You've regenerated, and I thought you looked familiar Harmony, just couldn't put my finger on it, but then again you always were better at disguises " she tells us looking at both of us with disbelief and I nod but then shake my head not understanding.

"Wait, what, when do we need disguises, and why?" I question turning to the Doctor.

"Yeah. Half a dozen times since we last met." the Doctor says ignoring me and looking at Sarah Jane sadly.

"You look… incredible." Sarah Jane breathes out.

"So do you." the Doctor says back to her.

"Huh. I got old. What are you two doing here?" Sarah Jane says shaking her head.

"You are not old, you are like wine the more it ages, the better it is" I tell her and she laughs at me trying to get her to smile.

"Well, UFO sighting, school gets record results. I couldn't resist. What about you?" the Doctor says sticking his hand in his pocket of his coat.

"The same." Sarah Jane says and the Doctor's smile goes wide and he chuckles. "I thought you'd died. I waited for you and you didn't come back, and I thought you must have died, and I thought that something worse had happened to Harmony as she jumped around, what would happen if you were gone" Sarah Jane says distraughtly.

"I lived. Everyone else died." the Doctor said softly and I squeeze his hand even though I knew that wasn't true, but since he technically hadn't done it a second time around, or even a third and it would be a while before that even happened with the Zygons.

"What do you mean?" Sarah Jane asks confused.

"Everyone died, Sarah." the Doctor says with saddened eyes but no emotion on his face.

"I can't believe it's you." Sarah Jane whispers softly and then Mickey screams making clear my throat trying not to laugh.

"Okay, now I can!" she says happily and we run off only to run into Rose

" Did you hear that? Who's she?" Rose says sizing up Sarah Jane.

"Rose, Sarah Jane. Sarah Jane, Rose." the Doctor says moving his head from Rose to Sarah Jane, then back to Sarah Jane to Rose and moving his hand introducing them.

"Hi. Nice to meet you. You can tell you're getting older, Doctor. You and Harmony's assistants are getting younger." Sarah Jane says to the Doctor and shakes Rose's hand.

"I'm not their assistant" Rose spits out seemingly offended.

"No? Get you, tiger." Sarah Jane says to us and the Doctor rubs the back of his head.

"Sarah I am deeply hurt, I am very happy with RS, and wouldn't go for anyone else" I say placing my hands over my heart like I was hurt, then the Doctor grabbed my arm and pulled me along both Rose and Sarah Jane following us as we made our way to find Mickey.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

"Sorry! Sorry, it was only me. You told me to investigate, so I started looking through some of these cupboards and all of these fell on me." Mickey says as he tries to pick up the rats and then stands up pointing to where the rats came from.

"Oh, my God, they're rats. Dozens of rats. Vacuum packed rats." Rose says disgusted.

"Yup, rats" I say picking them up and holding them as far away from my face as possible with a disgusted look.

"And you decided to scream." the Doctor says to Mickey as he holds a packed rat in his hand.

"It took me by surprise!" Mickey defends himself.

"Like a little girl?" the Doctor mimics a little girls voice.

"It was dark! I was covered in rats!" Mickey says clearly upset.

"Nine, maybe ten years old. I'm seeing pigtails, frilly skirt." the Doctor insults Mickey and I jab my elbow into his side as Rose tries to steer the conversation away from Mickey and onto the rats.

"Hello, can we focus? Does anyone notice anything strange about this? Rats in school?" Rose says trying to get us to start thinking why.

"Well, obviously they use them in Biology lessons. They dissect them. Or maybe you haven't reached that bit yet. How old are you?" Sarah Jane says and directs the last bit to Rose making me hold back a groan, 'great the jealousy games have begun all competitors please start insulting each other' I think to myself.

"Excuse me, no one dissects rats in school anymore. They haven't done that for years. Where are you from, the dark ages?" Rose says bitterly back to Sarah Jane and the Doctor looks between the two clearly oblivious as to why they were talking like that to each other.

"Anyway, moving on. Everything started when Mister Finch arrived. We should go and check his office" the Doctor says and throws the packed rat at Mickey making him flinch and instantly push it away from him and he drags me with him to Flinch's office.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

"I don't mean to be rude or anything, but who exactly are you?" Rose says through her teeth.

"Sarah Jane Smith. I used to travel with the Doctor and Harmony" Sarah Jane she says back.

"Oh. Well, he's never mentioned you, neither has Harmony" Rose says nonchalantly.

"Oh, I must've done. Sarah Jane. Mention her all the time." the Doctor says and itches his nose, trying to get out of

"Uh, because I haven't done anything with Sarah yet, technically it's the first time meeting her?" I say in a question like way biting my lip, though doesn't mean future me hasn't but haven't at this point

"Hold on. Sorry. Never." Rose says feigning thinking about her.

"What, not even once? He didn't mention me even once?" Sarah Jane says he mouth opening agape upset that he hadn't mentioned her.

"Ho, ho, mate. The missus and the ex. Welcome to every man's worst nightmare" Mickey says placing his hand on the Doctor's shoulder and I grab Mickey's arm as the Doctor follows Sarah Jane and Rose.

I clear my throat and glare at Mickey "Frist thing technically his missus would be the Tardis, she is always there for him, second it's more like a friend who cares about you but you haven't talked in a while, meets your current friend who seems to know a lot about you but not as much as the other." I tell Mickey as we walk into Flinch's office the Doctor, Rose, and Sarah Jane in front of us.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

"Maybe those rats were food," The Doctor said as he used the sonic to open the door to Mr. Finch's office.

"Food for what?" Rose asks.

He opened the door and peered inside. There was series of strange noises coming from the room.

"Rose, Harmony" The Doctor started off. "You know you used to think all the teachers slept in the school?" he says and walks inside his eyes trained on the ceiling. "Well, they do." he whispers out and we looked inside and my eyes widened at the sight of these bat-like creatures who I knew were the Krillitanes were hanging upside down from the ceiling.

"No way!" Mickey says and turned on his heels, running off. The others follow more sedately. One wakes when the Doctor shuts the door and grabbing my hand.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

We ran out of the front doors of the school, still holding hands.

"I am not going back in there. No way." Mickey says breathing heavily from running and moving his hands as emphasizing that he was not going back in there, also had wide eyes with fear in them.

"Those were teachers." Rose breathes out heavily.

"When Finch arrived, he brought with him seven new teachers, four dinner ladies and a nurse. Thirteen. Thirteen big bat people. Come on." the Doctor says and I groan as he makes his way back inside not wanting to go back in either.

"Come on? You've got to be kidding!" Mickey yells.

"I need the Tardis. I've got to analyze that oil from the kitchen." the Doctor told Mickey, turning to him.

"I might be able to help you there. I've got something to show you." Sarah Jane says and I knew she was talking about K9 which made me jump up and down pulling the Doctor in the direction that Sarah was headed, which was to her car.

"Yes, yes, yes finally getting to the fun part!" I exclaim and try to catch up with Sarah Jane wanting to see K9.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

Sarah went and unlocked her car opening the trunk of the car to show something covered by a towel and I instantly remove it and look at K9 in awe.

"K9!" the Doctor exclaims happily. "Rose Tyler, Mickey Smith, allow me to introduce K9. well, K9 Mark Three to be precise." the Doctor says happily inspecting K9

"Why does he look so disco?" Rose says clearly not impressed.

"Oi!" me and the Doctor say at the same time.

"Listen, in the year five thousand, this was cutting edge. What's happened to him?" the Doctor says upset at the way K9 looks.

"Oh, one day, he just, nothing." Sarah Jane says shrugging and then dropping her arms.

"Well, didn't you try and get him repaired?" the Doctor says upset.

"Yeah totally, she could just walk in a mechanic shop and be like 'oh I have this robot dog from the year five thousand and want him repaired' not going to happen Doctor" I tell him and Sarah Jane also picks at him for that.

"Harmony's right, it's not like getting parts for a Mini Metro, Beside, the technology inside him could rewrite human science. I couldn't show him to anyone." Sarah Jane says and moves a cord out of the way the turns to look at the Doctor.

"Ooh, what's the nasty lady done to you, eh?" the Doctor says as if he were talking to a baby and Mickey give him a weird look and I just pet K9, though the way he looked was that he was getting rusty round the edges, I was slightly nervous knowing that one of the Krillitanes was watching us, but tried to ignore it.

"Look, no offence, but could you three just stop petting for a minute? Never mind the tin dog. We're busy." Rose says clearly annoyed.

"I call being shotgun" I yell and go to the side door only to get in and see the steering wheel on the right side and groan as the Doctor gets in onto my left and look up to see Sarah look at me with confusion.

"Don't, just don't it's on the wrong side" I say blushing due to embarrassment and getting out to slide in and only be stuck between both Rose and Mickey.

"What did you mean by shotgun?" Mickey asks me on the way to where we were going.

"It means that If you call shotgun, you get the privilege to sit in the passenger seat in front, next to the driver, which is what I wanted, so that I wouldn't be squished as I am now" I say trying to move a bit but was too squished to move.

"Oh, I guess that makes sense" Mickey says and I roll my eyes.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

When we got to the coffee shop I sat next to the Doctor and tried to help him fix K9 as Sarah Jane watched us and Mickey and Rose watched us from a distance.

"I thought of you on Christmas Day. This Christmas just gone? Great big spaceship overhead. I thought, oh yeah, I bet he's up there." Sarah Jane comments as the Doctor is fixing K9.

"Right on top of it, yeah." the Doctor tells her glancing at her then back at K9.

"Harmony? And Rose?" Sarah Jane asks.

"She was there too. They both were" the Doctor tells her.

"Spoiler, can't tell me things that haven't happened to me yet" I joke and nudge the Doctor while he rolls his eyes at me.

"But you know what happens anyway" he tells me.

"Yea, I guess you are right, but still things change or have changed, so it might be a bit different" I tell him but he just ignores me and continues to fix K9.

"Did I do something wrong, because you never came back for me. You just dumped me." Sarah Jane says looking away then back at the Doctor.

"I told you. I was called back home and in those days humans weren't allowed." the Doctor tells her.

"I waited for you. I missed you." Sarah Jane says looking at him sadly.

"Oh, you didn't need me. You were getting on with your life." the Doctor brushes her off.

"You were my life. You know what the most difficult thing was? Coping with what happens next, or with what doesn't happen next. You took me to the furthest reaches of the galaxy, you showed me supernovas, intergalactic battles, and then you just dropped me back on Earth. How could anything compare to that?" Sarah Jane says upset.

"All those things you saw, do you want me to apologize for that?" the Doctor asks her.

"No, but we get a taste of that splendor and then we have to go back." Sarah Jane says.

"Look at you, you're investigating. You found that school. You're doing what we always did." the Doctor says smiling at her.

"You could have come back." Sarah Jane tells him.

"I couldn't." the Doctor says softly.

"Why not?" Sarah Jane asks him but he doesn't answer and keeps working on K9.

"It wasn't Croydon. Where you dropped me off, that wasn't Croydon." Sarah Jane says seemingly upset that he didn't answer.

"Where was it?" the Doctor asks her stopping with what he was doing and looking at her.

"Aberdeen." Sarah Jane forcefully upset, then again Aberdeen is in Scotland and is not even near Croydon.

"Right. That's next to Croydon, isn't it?" the Doctor asks not really looking as guilty as I had hoped.

"Not even close, you dropped her off in Scotland, not England, idiot" I say elbowing the Doctor just as K9 comes back to life.

"Oh, hey. Now we're in business." the Doctor says drumming on the table then standing up and moving in front of K9 pulling me up as well.

'Master, Mistress'

"He recognizes me." the Doctor says grinning happily,

"Mistress, I'm Mistress?" I question confused as to why he was calling me that.

'Affirmative'

"It was your idea, Harmony, you wanted a pet. Rose, give us the oil." the Doctor says calling Rose over and she gets up and walks over handing the jar to the Doctor as he sticks his finger in it.

"I wouldn't touch it, though. That dinner lady got all scorched." Rose says pointing at it then making hand motions when she said scorched.

"I'm no dinner lady. And I don't often say that." the Doctor says as he smears a sample on to K9's probe, then sets the jar aside. "Here we go. Come on, boy. Here we go."

'Oil. Ex…ex…ex extract. Ana… ana…analyzing'

"Listen to him, man. That's a voice." Mickey says while laughing and I glare at him.

"Careful. That's my dog." Sarah Jane says defending K9.

'Confirmation of analysis. Substance is Krillitane Oil.'

"They're Krillitanes." the Doctor says his eyes wide and turns to look at me and I shrug.

"You needed K9, and I wanted to see K9, if I told you we wouldn't have gotten to see K9, sorry. Plus we needed to see Sarah Jane" I tell him and he ponders for a bit then nods at my answer as to why I didn't tell him.

"Is that bad?" Rose asks looking at the Doctor.

"Very. Think of how bad things could possibly be, and add another suitcase full of bad." the Doctor syas his arms crossed over his chest thinking.

"And what are Krillitanes?" Sarah Jane asks confused.

"They're a composite race. Just like your culture is a mixture of traditions from all sorts of countries, people you've invaded or have been invaded by. You've got bits of Viking, bits of France, bits of whatever. The Krillitanes are the same. An amalgam of the races they've conquered. But they take physical aspects as well. They cherry pick the best bits from the people they destroy. That's why I didn't recognize them. The last time I saw Krillitanes, they looked just like us except they had really long necks." the Doctor says looking a bit unhappy.

"What're they doing here?" Rose asks.

"It's the children." I whisper softly and the Doctor's eyes go wide.

"They're doing something to the children." the Doctor says.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

Rose, the Doctor, and I were walking out of the coffee shop, when Rose started getting rather upset that the Doctor and I hadn't told her about previous companions, I was more concerned about Finch watching us.

"How many of us have there been travelling with you?" Rose asks annoyed with the Doctor and apparently me.

"Does it matter?" the Doctor asks her.

"Yeah, it does, if I'm just the latest in a long line." Rose says to him clearly upset.

"As opposed to what?" the Doctor asks her turning around to look at her.

"I thought you and me, and Harmony were. I obviously got it wrong. I've been to the year five billion, right, but this? Now this is really seeing the future. You just leave us behind. Is that what you're going to do to me?" Rose asks her eyes glistening with unhappiness.

"No, that is not what happens to companions Rose, and…we wouldn't leave you behind, never." I tell her firmly taking her hand and squeezing it tightly, not wanting to think about how she ends up in the Parallel universe, but she will end up happy there eventually.

"No. Not to you." the Doctor automatically says after me.

"But Sarah Jane? You were that close to her once, and now you never even mention her. Why not?" Rose asks upset as to if she left or something happened that he would never mention her either.

"We don't age. I regenerate, Harmony stays the same." the Doctors says.

"What is that supposed to mean 'Harmony stays the same'?" I but in before the Doctor can finish.

"Not now Harmony" the Doctor turns to me then turns back to Rose "But humans decay. You wither and you die. Imagine watching that happen to someone who you" the Doctor tells her.

"What, Doctor?" Rose says looking at the Doctor then looking at me for what he was going to say but I just shake my head, knowing he was going to say something that he cares for her, maybe it is as something else, like a sister or something?

"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." the Doctor says looking at Rose sadly.

"You are not alone, not while I'm around" I tell him sternly then flinch forgetting about Finch.

"Time Lord." Finch hisses out and the Doctor looks up. One of the Krillitanes swoops down. We all duck and it flies off.

"Was that a Krillitane?" Sarah Jane asks as it flew away but the Doctor doesn't answer only watches it.

"But it didn't even touch her. It just flew off. What did it do that for?" Rose asks the Doctor didn't answer so I just said what I at least thought as what it seemed it was there for.

"Because it wanted some answers, and it got what it wanted" I tell her. "Sarah Jane how about in the morning we meet back at the school and solve this once and for all" I say turning to Sarah Jane and she nods.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

Next morning, while the students were arriving at the school the Doctor, Rose, Sarah Jane, Mickey, and I were in the school yard the Doctor assigning orders to everyone.

"Harmony, Rose and Sarah, you go to the Maths room. Crack open those computers, I need to see the hardware inside. Here, you might need this." the Doctor says in leader mode and Rose holds out her hand, but the Doctor gives the screwdriver to Sarah.

"Mickey, surveillance. I want you outside." the Doctor says not turning to look at Mickey and putting his hands in his pockets.

"Just stand outside?" Mickey asks confused as to why all he would have to do would be outside.

"Here, take these you can keep K9 company." Sarah Jane says and throws Mickey her car keys.

"Don't forget to leave the window open a crack." the Doctor says not looking back at Mickey's face.

"But he's metal!" Mickey yells in response.

"I didn't mean for him." the Doctor yells back.

"What're you going to do?" Rose asks the Doctor.

"It's time I had a word with Mister Finch" the Doctor says not looking very happy and I kiss his cheek before we head into the classroom with the computers.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

Sarah isn't making progress with the school computers, and I wasn't even going to try to use my sonic because I knew it wouldn't work.

"It's not working." Sarah Jane says as she tries to get the sonic to work.

"Give it to me." Rose says taking the sonic from Sarah and going under the desk to where the wires of the computer were.

"Used to work first time in my day." Sarah Jane says.

"Well, things were a lot simpler back then" Rose says back from under the desk.

"Rose! Don't be rude, please" I try to get her to stop but the Sarah tries and picks up the conversation.

"Rose, can I give you a bit of advice?" Sarah Jane asks Rose.

"I've got a feeling you're about to." Rose says as she comes back from under the desk to look at the commuter.

"I know how intense being a companion is with the Doctor can be, and I don't want you to feel I'm intruding." Sarah Jane starts to say.

"I don't feel threatened by you, if that's what you mean." Rose says interrupting her.

"Right. Good. Because I'm not interested in picking up where we left off." Sarah Jane tells her.

"No? With the big sad eyes and the robot dog? What else were you doing last night?" Rose says with an attitude.

"I was just saying how hard it was adjusting to life back on Earth." Sarah Jane tells her.

"The thing is, when you two met they'd only just got rid of rationing. No wonder all that space stuff was a bit too much for you." Rose says rudely.

"I had no problem with space stuff. I saw things you wouldn't believe." Sarah Jane counters Rose's idea.

"Sarah Jane, don't..." I start to say but Rose cuts me off.

"Try me." Rose says and smirks.

"Mummies." Sarah Jane says.

"I've met ghosts." Rose says.

"Robots. Lots of robots." Sarah Jane says.

"Slitheen, in Downing Street." Rose says with more force.

"Raxacoricofallapatorians" I correct her under my breath.

"Daleks!" Sarah Jane tells her.

"Met the Emperor." Rose says with a roll of her eyes.

"Anti-matter monsters." Sarah Jane says picking up the pace at countering Rose.

"Gas masked zombies." Rose says right after Sarah Jane.

"Real living dinosaurs." Sarah Jane counters.

"Real living werewolf." Rose yells out.

"The Loch Ness Monster!" Sarah Jane yells out.

"Seriously?" Rose asks and Sarah Jane covers her mouth with both hands and turns away from Rose. "Listen to us. It's like me and my mate Shireen. The only time we fell out was over a man, and we're arguing over the Doctor." Rose chuckles then moves her hair back behind her right ear.. "With you, did he do that thing where he'd explain something at like, ninety miles per hour, and you'd go, what? and he'd look at you like you'd just dribbled on your shirt? Harmony tends to do that too" Rose asks Sarah Jane.

"Hey! I'm right here, no need to insult me further, and you both are rather rude and annoying at the moment" I say crossing my arms and huffing at them insulting and making a joke out of both me and the Doctor. "I do not talk too fast" I mumble

"All the time. Does Harmony and him still stroke bits of the Tardis?" Sarah Jane asks trying not to laugh.

"Yeah! Yeah, they do. I'm like, do you three want to be alone?" Rose says and both her and Sarah start to laugh.

"Rose! Sarah Jane! Stop laughing, stop it, it is not funny, she is a sentiment being and she is amazing" I say trying to tell them off but they end up laughing more and I just huff when the Doctor enters.

"How's it going?" the Doctor says as he walks in but once they see him they just burst out laughing more. "What? Listen, I need to find out what's programmed inside these." the Doctor says gesturing with his head at the computers and Rose just points the sonic at him and both her and Sarah Jane are now in hysteria.

"What? Stop it! Harmony what did I miss that is so funny?" he asks turning to me and I just roll my eyes.

"Doesn't matter, let's just get this over with please" I say still pouting at why they were laughing.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

"No, no. This classroom's out of bounds. You've all got to go to the South Hall. Off you go. South Hall!" Rose yells turning the children away at the door as the Doctor tries to see what was programmed on the computers

The Doctor does his old trick of looping wires around his neck and shoulders as he tries to get inside the computer

"I can't shift it." the Doctor says irritated.

"I thought the sonic screwdriver could open anything!" Sarah Jane asks confused as to why the sonic wasn't working.

"Anything except a deadlock seal." the Doctor says.

"And wood, can't forget wood!" I say jumping in making me give me a 'not now' look and I just shrug.

"There's got to be something inside here. What're they teaching those kids?" the Doctor says and he sets the piece of the computer down to go look at the computer.

"You wanted the program? There it is." Sarah Jane says as alien symbols are all on the computer screens and I bite my lower lip.

"Some sort of code." the Doctor says and studies it more "No. No, that can't be" he says his eyes going wide with disbelief.

"Unfortunately it is, but we need to stop it, for the sake of the children" I say and reach for the Doctor's hand.

"The Skasis Paradigm. They're trying to crack the Skasis Paradigm." the Doctor says.

"The Skasis what?" Sarah Jane asks.

"The God maker. The universal theory. Crack that equation and you've got control of the building blocks of the universe. Time and space and matter, yours to control." the Doctor says getting upset.

"What, and the kids are like a giant computer?" Rose asks.

"Yes. And their learning power is being accelerated by the oil. That oil from the kitchens, it works as a, as a conducting agent. Makes the kids cleverer." the Doctor says and paces away then leans against one of the computers.

"Which is why I didn't eat any, disgusting" I say and Rose's eyes go wide at what I said.

"But that oil's on the chips. I've been eating them." Rose says a slight shock in her voice.

"What's fifty nine times thirty five?" the Doctor asks her.

"Two thousand and sixty five." Rose says without emotion and the Doctor tilts his head as if to say 'well there you go' "Oh, my God." Rose says her eyes going wide.

"But why use children? Can't they use adults?" Sarah Jane asks.

"Sarah a child has much more imagination than an adult has." I tell her.

"No, it's got to be children. Like Harmony said The God maker needs imagination to crack it." the Doctor says and walks a bit then turns to us. "They're not just using the children's brains to break the code, they're using their souls." the Doctor tells us and the Headmaster has entered the room.

"Let the lesson begin." Finch says and the Doctor turns around to look at him. "Think of it, Doctor. With the Paradigm solved, reality becomes clay in our hands. We can shape the universe and improve it." Finch says walking closer to the Doctor.

"Oh yeah? The whole of creation with the face of Mister Finch? Call me old fashioned, but I like things as they are." the Doctor says narrowing his eyes at Finch.

"You act like such a radical, and yet all you want to do is preserve the old order? Think of the changes that could be made if this power was used for good." Finch says trying to convince the Doctor.

"What, by someone like you?" the Doctor asks raising an eyebrow.

"No, someone like you. The Paradigm gives us power, but you could give us wisdom. Become a God at my side. Imagine what you could do. Think of the civilizations you could save. Perganon, Assinta. Your own people, Doctor, standing tall. The Time Lords reborn." Finch tells the Doctor just above a whisper.

"Doctor, don't listen to him." Sarah Jane tells the Doctor.

"And you could be with him throughout eternity. Young, fresh, never wither, never age, never die. Their lives are so fleeting. So many goodbyes. How lonely you must be, Doctor. Join us." Finch says and goes to walk closer to Sarah Jane and the Doctor turns around with a blank expression.

"I could save everyone." the Doctor breathes out.

"Yes." Finch says to him.

"I could stop the war." the Doctor breathes out thinking of the possibilities of doing so.

"No. The universe has to move forward. Pain and loss, they define us as much as happiness or love. Whether it's a world, or a relationship, everything has its time. And everything ends." Sarah Jane says and the Doctor takes a few seconds to think about what she said before he rushes grabbing a chair at the big screen, smashing it.

"Out!" the Doctor yells and we make our way to the stairs and down them only to meet Mickey and Kenny at the bottom of the staircase.

"What is going on?" Mickey yells with wide eyes.

"The Krillitanes are coming" I tell him as we make our way to the cafeteria and Mickey looks somewhat scared with fear written on his face.

Finch walks in followed by the bats. "Are they my teachers?" Kenny asks.

"Yeah. Sorry." the Doctor says while keeping his eyes trained on the Krillitanes.

"We need the Doctor alive. As for the others? You can feast." Finch the other Krillitanes.

The Krillitanes swoop. Kenny, Rose, Mickey, and Sarah Jane hide under the tables, while the Doctor keeps me behind him and swings a chair at the Krillitanes. Suddenly a laser beam fells one of the Krillitane causing it to fall making Finch yell becoming furious.

"K9!" Sarah Jane yells.

'Suggest you engage running mode, mistress.'

"Come on!" the Doctor says and we all run while K9 shoots the Krillitanes.

"K9, hold them back!" the Doctor yells as we run.

'Affirmative, master. Maximum defense mode'

The Doctor seals the doors of the cafeteria and we made our way into the physics lab, the Doctor trying to figure out what to do.

"It's the oil. Krillitane life forms can't handle the oil." the Doctor says victoriously and Rose gets up out of the seat that she was sitting on. "That's it! They've changed their physiology so often, even their own oil is toxic to them. How much was there in the kitchens?" the Doctor asks Rose.

"Barrels of it." Rose says as we all turn to the door where the Krillitanes are battering at the door.

"Okay, we need to get to the kitchens. Mickey." the Doctor starts giving out orders.

"What now, hold the coats?" Mickey says sarcastically clearly still upset about keeping watch.

"Get all the children unplugged and out of the school. Now then, bats, bats, bats. How do we fight bats?" the Doctor says trying to think out loud, when Kenny sets off the fire alarm making the Doctor grin. The noise hurts the Krillitane's ears and we are able to quickly escape.

'Master. Mistress'

"Come on, boy. Good boy" the Doctor says to K9.

The Doctor tries his sonic screwdriver on the barrels of oil, but they won't open "They've been deadlock sealed. Finch must've done that. I can't open them." the Doctor says unhappy.

'The vats would not withstand a direct hit from my laser, but my batteries are failing.'

"Right. Everyone out the back door. Harmony, K9, stay with me." the Doctor says and grabs my hand dragging me off with him and off to the cafeteria where the Doctor lines up the oil barrels for K9 to shoot at.

'Capacity for only one shot, Master, Mistress. For maximum impact, I must be stationed directly beside the vat.'

"But you'll be trapped inside." the Doctor says and moves away from the barrels and squats next to K9.

'That is correct.'

"We can't let you do that K9" I say squatting down to pet his metal head.

'No alternative possible, Master, Mistress'

The Doctor and I turn our heads as we hear the Krillitane's. "Oh K9, you great dog, goodbye and I can't wait to meet you again" I say and pet his head and kissed the top of it with a sad smile and looks at the Doctor as he said his goodbyes.

"Goodbye, old friend." the Doctor

'Goodbye, Master, Mistress'

"You good dog." the Doctor

'Affirmative.' K9 says and his ears move side to side and his tail wags.

The Doctor seals the door, and Sarah looks at us but we grab her hand so we can make it out before the whole place explodes.

"Where's K9?" Sarah Jane asks confused as to where he was.

"We need to run." the Doctor says as we make a run for it.

"Where is he? What have you done!" Sarah Jane says.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

We make it out just in time as the school goes KaBOOM! The children rejoice as paper rains down on them.

"Yay! Kenny! Kenny! Kenny! Kenny!" the Children cheer and the Doctor turns to look at Sarah Jane.

"I'm sorry." the Doctor apologizes.

"It's all right. He was just a daft metal dog. It's fine, really." Sarah Jane insists that she is fine but bursts into tears and I hug her comforting her while the Doctor at least tries, but I seem to give her more comfort.

"It's okay Sarah Jane" I sooth her while rubbing her back.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.

The Doctor had to relocated the Tardis from the destroyed school to Belle Vue Park, where Sarah and I were just as the Doctor came out.

"Cup of tea?" he asks gesturing with his head to the Tardis and Sarah goes into the Tardis, then the Doctor and then me following behind him and closing the door.

"You've redecorated." Sarah Jane says as she looks around.

"Do you like it?" the Doctor asks her.

"Oh, I, I do. Yeah. I preferred it as it was, but er, yeah. It'll do." Sarah Jane says as she looks around more.

"I love it." Rose says grinning while leaning on the railing.

"She is always perfect, no matter what she looks like" I say happily leaning against the side of the console room.

"Hey, you what's forty seven times three hundred and sixty nine?" Sarah Jane asks Rose.

"No idea. It's gone now. The oil's faded." Rose says shaking her head.

"But you're still clever. More than a match for them" Sarah Jane says gesturing to both me and the Doctor.

"You and me both. Doctor?" Rose say then turns to the Doctor.

"Er, we're about to head off, but you could come with us." the Doctor says giving Sarah a small smile.

"No. I can't do this anymore." Sarah Jane says and the Doctor's smile fades. "Besides, I've got a much bigger adventure ahead. Time I stopped waiting for you and found a life of my own."

"Can I come?" Mickey says and Sarah Jane looks at him confused as to why he would want to join her and he shakes his head "No, not with you," he says and holds up a hand as if to say 'no offence' "I mean with you. Because I'm not the tin dog, and I want to see what's out there." he says turning to the Doctor.

I notice Rose cross her arms over her chest and mouth a 'no' to the Doctor but he must not have seen.

"Oh, go on, Doctor. Sarah Jane Smith, a Mickey Smith. You need a Smith on board." Sarah Jane says trying to convince the Doctor.

"Okay then, I could do with a laugh." the Doctor says leaning against the console and Mickey gets a wide smile.

"Rose, is that okay?" Mickey asks Rose concerned that she didn't want him there.

"No, great. Why not?" Rose says sarcastically and Sarah must of noticed the face she was giving.

"Well, I'd better go." Sarah Jane says to us and pulls Rose over closer to her to talk to her to tell her about staying with the Doctor no matter what and hugs her. "Find me, if you need to, one day. Find me." Sarah Jane says and she goes to leave and I kiss Rose's cheek.

"I have to go too, better get going as well….ah DOCTOR!" I yell as I am instantly dipped down like you would to dip a dancing partner and the Doctor with a serious look on his face.

"If you have to go, no more marrying anyone you meet, and I mean it, you've already mentioned something about a wife, and I don't like it" he says and I giggle at him looking that way making me frown.

"She is very important, one day you will realize just how important she is, but I have to go" I say and pull the Doctor's head closer so I can kiss him and he moves me so I am standing again.

"If I have to get along with her I will at least try to, but that doesn't mean I will, can't have someone else stealing my wife, now can i?" he jokes and I nod kissing his cheek.

"Got it, and you did fix K9 right?" I ask him and he nods.

When I turn to go outside I notice a bag now next to the door with my name on it and I picked it up looking to find workout gym clothing so whatever it was going to do was going to be running, or just plain working out.

"Yes, now let me say goodbye to Sarah Jane properly" he tells me following me out.

"It's daft, but I haven't ever thanked you two for that time. And like I said, I wouldn't have missed it for the world." Sarah Jane tells us.

"Something to tell the grandkids." the Doctor says with a smile.

"Oh, I think it'll be someone else's grandkids now." Sarah Jane says and give me a sly smile and I glare at her playfully turning away because I knew that I was blushing.

"Right. Yes, sorry. I didn't get a chance to ask. You haven't? There hasn't been anyone? You know." the Doctor asks her.

"Well, there was this one guy. I travelled with him for a while, but he was a tough act to follow, as well as a wife. Goodbye, Doctor. Harmony" Sarah Jane says.

"Oh, it's not goodbye." the Doctor says brushing off the goodbyes since he hates goodbyes.

"Do say it. Please. This time. Say it." Sarah Jane asks him.

"Goodbye, my Sarah Jane." the Doctor says and lifts her off her feet in a big hug, then goes back inside the Tardis, but not before kissing me again.

Sarah looks at me confused and I just go to walk with her only for when the Tardis starts to dematerialise she turns back to see K9 all fixed up.

"K9!" Sarah Jane yells happily.

'Mistress.'

"But you were blown up." Sarah Jane says kneeling to look at him better.

'The Master rebuilt me. My systems are much improved with new undetectable hyperlink facilities.'

"Oh, he replaced you with a brand new model." Sarah Jane says grinning and turning to me.

'Affirmative.'

"Yeah, he does that. Come on, you. Home. We've got work to do." Sarah Jane says and gets up only to turn to me.

'Affirmative'

"Now, Harmony why are you still here?" she asks me as I walk her back to her car.

"They go straight on an adventure, rather not do that yet, and anyway it seems that it was a better idea, we will see you again Sarah Jane don't doubt that, plus I never leave someone on their own, I will visit" I tell her as everything seems to fade away and I find myself in what seems to be a living room.
