A week later…

"Jenna, I don't think I can do this", Luke said as they neared Park Vale School. It was his first day and naturally he was very nervous. Jenna had decided to walk him to school so she had plenty of time to assure him that everything was going to be ok.

"Of course you can! You're nervous but that's perfectly normal", Jenna assured him "I was nervous on my first day at school too".

"Really?" Luke asked.

"Really", Jenna replied "I was so nervous about going that I'd actually tried to barricade myself in my room. Mum actually had to bribe me with a new set of paint brushes to get me to go. When it got to the end of the day, I realised that I'd actually enjoyed my first day and I couldn't wait to do it all over again! And I'm pretty sure you'll enjoy yourself too Luke. Plus, you're not alone. You've got Maria".

Luke smiled, finding some comfort in her words. The pair stopped near the school. "Have a good day and either mum or myself will meet you out here about 3:30, ok?" Jenna said.

"Ok. Thanks for the talk Jenna", Luke said.

"It's what big sisters are for. Making little brothers feel better", Jenna told him. The teenaged boy smiled again before he headed across the road to the school.

"You need to be careful", a familiar voice spoke up. Jenna glanced to the side and saw 12th Naiyah standing there looking at the school "an old enemy is looking for revenge".

Before Jenna could ask her what, the Time Lady disappeared. She was surprised by her visit, she honestly wasn't sure if she was going to see any version of Naiyah after what happened with the Master and the paradox machine. She was also curious by her warning. She wondered which old enemy could be looking for revenge. She hoped that it wasn't the Daleks. She'd honestly had enough of them to last several lifetimes.

Jenna turned and walked away, heading back to 13 Bannerman Road. She had some thinking to do.

Jenna glanced over at her mother and shook her head seeing the woman start to pace again. She'd been doing that for the last hour on and off. "Mum, he's going to be perfectly fine. Luke's a smart kid", Jenna assured her.

"I know he is", Sarah Jane said "It's just… what if he gets lost? Or what if he gets picked on? I do hope we've taught him enough to get by…"

Jenna set her brush down and went over to her mother, taking her hands forcing her to stop pacing. "Mum. Luke is going to be fine", she repeated "you, me and the Doctor have taught him everything he could possibly need and more… in the Doctor's case. Getting lost in a new school is only natural… but I highly doubt he will. And if he does get picked on… well…big sister Jenna will have to do something about that".

Sarah Jane nodded, relaxing slightly from those words. "You're right Gen", she agreed "I just can't help but worry. I did the exact same thing when you were in Luke's place. Though I didn't really have anyone to assure me, not even my husband".

"Well you have me to assure you and I can promise you right now that I'll always be here when you need me. I'm not going anywhere", Jenna promised. She gave her hands a gently squeeze before letting go. Jenna went back to her easel and picked up her paint brush "And I'm most certainly not going to run off with some bimbo half my age", she added.

Sarah Jane laughed "no, you'll just run off with your alien boyfriend, who's several times older than you", she countered "speaking of, did he say where he was off to?"

Jenna shook her head "fraid not", she replied "he just told me that he was going off on a trip somewhere and said if I needed him to give him a call".

"Let's hope he's not getting into too much trouble", Sarah Jane remarked and Jenna laughed.

"He's an utter trouble magnet, mum. If it wasn't for my 'feelings', he probably would've gotten into even more trouble", she said.

"Good point", her mother conceded "do you fancy a cup of tea?" Sarah Jane asked.

"Sure", Jenna replied. Sarah Jane nodded and left the room. Jenna continued with the painting she was doing as a surprise for Maria. A little something she could hang on her bedroom wall. Hopefully she'll like it she thought. It was a recreation of the Carina Nebula but there was also a 3 hidden images within the painting that you could spot only if you looked very carefully. One was the Star Poet, the first alien Maria had seen. The second was of K9 and the third… well let's just say Jenna couldn't resist putting it in… was of the TARDIS.

A minute later the attic door opened and Sarah Jane entered carrying two cups of tea. "Thanks", Jenna said taking one. She took a sip "what do you think?" she asked nodding to the painting "recon Maria would like it?"

"I'm sure she would love it", Sarah Jane replied "you and she are pretty close", she commented.

"Well, she's been brought into our world of aliens and I know how overwhelming it can be. I felt that she could do with a friend", Jenna explained "me being a girl is also a plus".

Jenna waited by the front of the house with the finished painting. Sarah Jane had gone off to the school to go pick up Luke. Her mother's green car pulls up in the driveway at the same time that Maria's dad, Alan cycled up.

"Oh, I see, you've cadged a lift, have you?" he remarked when Maria got out of the car.

"I offered", Sarah Jane said.

"I don't know, Lady Muck, getting neighbours to chauffeur her around", Alan continued with a smile.

"Shut up, Dad", Maria muttered but she was smiling too.

"Maria I've got a little something for you", Jenna spoke up. She picked up the painting and showed it to the teen.

"That's for me?" Maria asked looking at the painting in amazement. Both Maria and Alan knew that Jenna was a decent painter as the brunette had helped them decorate their house. Alan had tried to pay her for all her help but Jenna wouldn't have any of it.

Jenna nodded "yep", she replied popping the p.

"I love it. Thank you", Maria said taking the painting from her.

"You're welcome", Jenna said.

"Have you ever considered doing commissions?" Alan asked.

"No I haven't", Jenna replied honestly "I just do it as a hobby".

"Well you should", Alan said "I recon there's people who'd pay for a Jenna Smith painting".

"I'll think about it", Jenna said.

"How was the big first day, then?" Alan asked turning to his daughter.

"Ok", Maria replied "A bit weird, though. The headmaster keeps farting". Either the headmaster has a stomach problem or he's a Slitheen in disguise Jenna thought she hoped it was the former. Though she couldn't help but recall Naiyah's warning about an older enemy. And she had met the Slitheen before.

"Really?" Alan asked sounding interested "What, noisy smelly ones or silent but deadlies?"

"Eugh!" Maria exclaimed.

"What?" Alan asked pretending that he hadn't said anything disgusting.

"The place stinks like batteries, and the canteen food was off", Luke added. Hm… wonder if that means anything… Jenna thought.

"I'll make you a proper tea. You go and get changed", Sarah Jane said.

Luke nodded "See you, Maria", he said before heading into the house. Jenna excused herself and headed into the house as well. She had some checking to do.

"I want a proper tea too", Maria said turning to her dad.

"Make it yourself", Alan countered "You might have a chauffeur, but I'm not your cook".

"Oh, whatever", Maria shot back in a joking tone.

"No, forget it, it's all right. We'll phone out for a curry. Can't have you straining yourself after your long voyage home, can we?" Alan asked.

"You think you're so funny", Maria laughed and she headed off across the road to her house. Sarah Jane couldn't help but smile at their playful banter. It was similar to the kind of banter she and Jenna would often have. It was also nice to see that Maria had a good relationship with her father. If only Will had been more like that towards our daughter…

She shook her head, breaking herself out of her thoughts "Anyway, the school can't be that bad. Jenna used to go there. And they've just built this", Sarah Jane took a newspaper from her bag which she'd picked up before collecting Luke and Maria from the school "Someone donated the money and this technology block was put up. It looks incredible".

"Hold on. I did an IT job in a school, in a new block that looks like that", Alan remarked nodding to the picture on the paper.

"Was it built by Coldfire Construction?" Sarah Jane asked.

"Yeah", Alan replied.

"Where was that?"

"On the other side of town. Saint Cheldons in Upminster", Alan answered "That place smelt odd. Sort of metallic…" he mused "Anyway, better go. Stop her ordering the entire menu. Bye". With that he headed off across the road with his bicycle.

Up in the attic Jenna was sitting at the computer staring at the image of the headmaster of Park Vale School. He was plump just like Joseph Green, General Asquith and Margret Blaine had been. Plump…unable to stop farting… Jenna held up her sketchbook which she'd opened onto the page which had the sketch of a Slitheen on it.

"The old enemy", she breathed.

"Are you sure you're feeling ok, Jenna?" Sarah Jane asked for the third time in the car on the way to Saint Cheldons the next morning. She'd noticed that her daughter had been acting differently yesterday afternoon. She was quieter than normal and she barely ate anything. And then there was the nightmare. Both Sarah Jane and Luke had been disturbed in the early hours of the morning by Jenna screaming. But Jenna refused to tell them anything about the nightmare. She was quite adamant in that fact.

"I'm feeling fine mum, honestly", Jenna replied.

"You know you can talk to me about anything", Sarah Jane continued "even about nightmares".

"I know", Jenna said "but I really don't want to talk about it just yet".

She did feel rather guilty about not telling her mother and Luke about her suspicions on the presence of Slitheen at the school but she had no definite proof other than the headmaster is overweight and keeps farting. Plus if he did turn about to be a Slitheen there is the matter of finding out why they were back on Earth. She didn't want make any confrontations especially when she had her mother and Luke to think about. Also Maria and her dad.

~St Cheldons Comprehensive school~

"Oh, it's hopeless, Miss Smith, Miss Kieran", the Headmistress cried as they walked down the stairs of the school "Even worse this term".

"I believe you had the wiring in your new block re-installed", Sarah Jane said.

"Didn't do any good. Computers keep crashing", the Headmistress told them as they reached the bottom of the stairs "And Look at this" she produced a bruised apple from her bag "Fresh this morning! Everything goes off" the woman put the apple back into her bag and continued walking, the 2 Smith's following "And there's that smell, like batteries".

"And this all started when you got your new technology block?" Jenna asked and the Headmistress nodded.

"Doesn't anybody care?" Sarah Jane questioned "Hasn't anyone tried to work out what's wrong?"

"One of the parent governors raised it at our meeting", the Headmistress replied.

"And?" Sarah Jane pressed.

"Fell off his bike the next morning!" the Headmistress answered "Three months in traction. Can't you feel it, Miss Smith? Miss Kieran" she asked "Like a thunderstorm's coming". At those words Jenna couldn't help but think back to that little adventure with the Isolus.

~flashback~

Fireworks exploded overhead, lighting up the dark sky in various colours. "You know what? They keep on trying to split us up, but they never ever will", Rose said.

The Doctor looked at her coming to a halt "Never say never ever", he warned.

"Nah, we'll always be okay", Rose said confidently "us three. Don't you reckon?" she looked at both Jenna and the Doctor who were now looking up at the sky.

"There's something in the air. Something's coming", the Doctor said quietly.

"What?" Rose asked wondering if she should be worried.

"A storm" Jenna replied seriously.

~end~

That 'storm' had caused Rose to be separated from herself and the Doctor forever. She couldn't lose anyone else. Not her mother. Not Luke. Not the Doctor. No one. If the Slitheen were the culprits behind all of this, they'd have to deal with HER. Jenna looked up and the CCTV camera, Sarah Jane following her gaze.

In an office somewhere, a plump woman looked her computer screen that was displaying the CCTV footage of the mother and daughter with a smile. "Hello, Miss Smith, Miss Kieran", she said with an evil laugh.

After having some lunch at a small café not too far from St Cheldons, Sarah Jane dropped Jenna home, the brunette having said that she wanted to get a little rest. Jenna watched her mother drive away, heading for Coldfire Construction before she stepped out of the house. She went over to her blue car and drove off towards the nearest supermarket. If they were dealing with Slitheen then they were going to need to stock up on vinegar.

~Playground~

"Someone looks happy", Maria remarked as she and Luke walked "I had double maths this afternoon".

"Science club was brilliant", Luke said happily "Mr Jeffrey's really nice. I think we're going to be friends".

"You don't make friends with a teacher", Maria said quickly not wanting Luke to get any ideas.

"Why not?" Luke asked.

"You just don't", Maria replied simply "Anyway, look, Sarah Jane phoned me. She wants us to look inside the new block".

"What are you doing?" a black boy asked suddenly coming up behind them, putting his arms around their shoulders. It was Clyde Langer, the boy they'd met yesterday.

"We're investigating the new block", Luke said before Maria could say anything.

"I left something in the new block", Maria said quickly and walked off.

"What is it with you and her?" Clyde asked as he and Luke watched her go "I've seen weird people. I know weird people. But you two? You're beyond weird".

"Go find some normal people then", Luke shot back and walked away after Maria. A smile appeared on his face as he walked. Jenna was going to be proud of him for that as it was her who'd given him advice on how to handle people who made comments like the ones Clyde had just made.

~Supermarket~

Jenna pulled into a parking space and got out of the car.

~Tech block~

"That's not right", Luke muttered as he wandered are the new building. He and Maria decided to split up to check over the building.

"I want answers", Clyde demanded having managed to catch up with Luke "Where are you from?"

"London", Luke replied distractedly as he took in the building as he walked "The layout of this building doesn't make any sense".

"But where have you been all your life?" Clyde asked "You don't know farting's funny. Where was your last school?"

"I've never been to school before", Luke replied.

"What, your mum and sister taught you at home?" Clyde questioned.

"No. Sarah Jane isn't my mum and Jenna isn't my sister", Luke stopped walking "There are sixteen classrooms in this building".

"Hold on. So what's Sarah Jane and Jenna to you?" Clyde asked.

"They adopted me", Luke answered.

"Why don't you call Sarah Jane, mum?" Clyde pressed.

"She doesn't want me to", Luke stated and continued walking "Jenna's got no problem with me calling her sister though", he added.

"But what about your real mum and dad?" Clyde asked.

"I haven't got a mum or dad", Luke replied. He was getting a bit annoyed with all the questions Clyde was asking. Sarah Jane wanted him and Maria to check out the building. How was he supposed to do that if Clyde kept asking him questions?

"Everybody's got a mum and dad. I have a dad, somewhere", Clyde said.

"This block measures about 1539 M², so double that for both floors…." Luke frowned when he worked out the answer and found that it wasn't quite right "The area of each room doesn't add up to that. So there's an empty space. Through there" he pointed down the corridor "I think you should go home".

Clyde quietly scoffed, shaking his head before he followed after Luke. There was something weird going on and he was going to find out what.

~Supermarket~

Jenna wrinkled her nose at the beans as she walked down the aisle, pushing the small trolley in front of her. "Evil beans", she muttered earning her a look from a shopper. She stopped in another aisle by the vinegar. Jenna regarded the different ones before she selected a brand and put 10 bottles in her trolley. It was a bit excessive but it was better safe than sorry. Jenna stopped by another aisle and picked up some plastic spray bottles.

~Computer science room~

Maria quickly hid under a desk as Mr Jeffrey entered the room. "Who's that? Hello?" Mr Jeffrey called. Maria kept her lips pressed together so she didn't make a noise. "I know you're in here. I can smell you" he his sniffed loudly "Oh, a little girl, fresh as a Jenna. Sugar and spice and all things nice" he said as he skipped right over to the desk Maria was hiding under. Mr Jeffery smacked his hands on the desk making the frightened girl jump but still she didn't make a sound "She really shouldn't be hanging around school after home time" Mr Jeffery moved back from the desk "Not when I've got no reason to hide in this stupid skin any longer".

~Supermarket~

Jenna walked out of the supermarket carrying her bags.

~Computer science room~

"After all, why should I hide?" Mr Jeffery asked. He reached up to his forehead and started to unzip it.

~Supermarket~

Jenna stopped dead a few feet away from her car and gasped, eyes widening. "Maria!" she shouted. The girl ran the last few feet to the vehicle, unlocking it as she went. Jenna dumped her bags on the front passenger seat and then turned on the ignition. She tore out of the car park nearly hitting a vehicle on the way out. But Jenna paid no attention to the blare of a car horn she'd gotten. She was more interested in getting to the school in time.
