Disclaimer : I don't own The Sarah Jane Adventures or anything you may recognize. I only own the girls: Fiona, Megan, and Ali.

A/N: Fiona is 17, Megan is 16,Ali is 14, and Luke is 13. Betaed by GleeJunkie007.

Sarah Jane would have driven the kids to school if Fiona hadn't stopped her, pointing out that she had a car and it would be less embarrassing for Luke on his first day to be dropped off by his older sister as opposed to his mother.

Fiona pulled Megan and Alison aside after watching Maria drag Luke off.

"Look after him." Fiona told them.

"You worry too much Fee. He's not a baby." Alison rolled her eyes.

"Technically, he is. But we'll look after him and so will Maria, so don't worry about it." Megan assured her older sister.

"We should get going, can't be late." Megan added, noting the time.

"I'll call you around lunch, okay?" Fiona waved and headed to her car.

They headed for the auditorium where the 'Back to school' assembly was. Megan spotted her friends and was about to head over to them when Alison nudged, pointing to the fourth row, where Luke and Maria sat, now apparently joined by another boy, whom was dark skinned and had a nearly shaved head. Shrugging, Megan followed her sister to where her brother and friend sat.

"Scootch," Megan tapped Maria on the shoulder, causing the girl to oblige.

Alison leaned over. "Luke,who's your friend?"

"He's not my friend and his name is Clyde Langer. He's only sitting with us until he finds cooler people to hang out with. "Luke said repeating what Clyde had said earlier.

"Oh well, sorry we're not cool enough for you. I'm Megan Smith and this is my sister Ali ."Megan said pointedly.

"Is the fact that your last name is the same as his a coincidence or what?" Clyde asked.

"He's our brother, "Alison told him.

"Oh. Okay." Clyde shrugged, the conversation ceased as the headmaster came up introduced himself and promptly farted. In which, sent ripples of laughter through the auditorium. He barked at the kids to shut up and Megan rolled her eyes. Their last headmaster wasn't so uptight; then she wondered what did happen to the former headmaster as he wasn't old enough to retire. But she then shrugged at the thought. he probably found a job at a different school or came into some money; there could be a number reasons.

There was a rustle of movement as everyone stood up. Clyde, Alison, and, Luke's year headed out of the auditorium.

On the tour of the school, Alison became bored. The headmaster droned on about the new science block. He then farted again and everyone laughed except Luke; he seemed confused on why everyone thought darting was funny.

"Why is farming funny? It's a normal human bowel movement. " Luke stated, Alison groaned smacking her forehead.

"It just is."Clyde said.

"But why? I don't understand ."Luke was about to say something else but Alison shoved a piece of candy in his mouth effectively shutting him up for the time being. The girls had started carrying candy in their purses because Luke had a tendency to blurt out whatever was on his mind. And somehow Luke always picked the worst times to speak his mind; it was easier to keep him quiet and have less people angry at him if he couldn't talk.

It would also lessen the possibility of people asking questions; that was something they didn't need.

"How are you two related anyway?"Clyde asked .

"Luke's adopted. He's been very sheltered."Alison explained, trying to find the right word. "He's not that bad, once you get used to him."

"If you say so." Clyde said dropping the subject. "It smells weird." He added after he realize the smell wasn't how farts usually smelled.

"Like batteries. " Luke piped up.

Alison looked thoughtful. Luke had a point the air. It did have a very distinctive odor that was sort of electric; but then she shrugged: it was probably nothing.

-Line break-

The rest of the day passed without an incident. Fiona was at the gates at half past four. She hadn't been able to call during lunch like she had wanted and was eager to hear about Luke's first day. She wondered if this was how mothers felt. She also was eager to know if Sarah Jane was just as eager to hear about his day, if not more. She had felt bad that she hadn't let her drive Luke to school on his first day, but she had seemed to understand.

As soon as they got home and as soon as he changed his clothes, Luke went up to the attic to talk to Sarah Jane. Fiona knocked on Alison's bedroom door.

"Come in." She turned towards her eldest sister.

"What's wrong, Fee?" Alison asked .

"Nothing. Was Luke okay?" Fiona replied, skipping to the question that was on her mind.

"The other kids think he's weird and he corrected the teachers several times." Alison told her. Ironically, though Luke didn't seem to get in trouble. She didn't know why maybe because he wasn't being disrespectful when he did correct the teachers and had such an innocent aura about him; most of the teachers just shrugged and let it go. She knew if it were her or anyone else they would have had detention.

The girls headed up to the attic where the rest of the family was gathered. Megan was on her phone as usual while Sarah Jane was on the computer and Luke was doing his homework.

Fiona glanced at the screen. "Coldfire Construction. Isn't that the company that built the new science block?"

"It isn't aliens, that's good." Sarah Jane said just as the power went out. Megan uttered a word that could not be repeated .

"Power's out,"Alison said unnecessarily.

Sarah Jane sighed "And guess who forgot to save her work." She decided to check her watch to see if she could figure out how long it would be. They were surprised to find the watch didn't work; it seemed to be have lost power as well. It was strange because the watch wasn't run by electricity.

The power shortage didn't last very long, maybe about ten minutes and just as quickly it came back on. They didn't think of it was anything to do with aliens. They chalked it down to one of those fluke things that happened; they didn't know then that was a mistake. The rest of the night passed uneventfully.

-Line Break-

The second day of school turned out to be more eventful than the first day. Not only did the science teacher and headmaster turn out to be aliens, but so was Luke's science club partner Carl; they were all aliens. However several good things did come from the disaster. They did defeat the aliens and and Clyde was incorporated into their little group and was trusted with their secret, which also meant being told Luke's real background.

He promised to keep their secret, but stated that they needed him.

"If anyone says you're not cool, I'll set them straight" Clyde told Luke. "You might have sisters, but if you ever want to talk about guy stuff, I'm your man. I'll be your Obi-Wan Kenobi and you'll be my padawan."

Luke looked confused "Huh?"

"You know Star Wars. Clyde said ,Luke still looked confused. Clyde turned towards the girls .

"He hasn't seen Star Wars ?" He sounded as if that was a major crime.

Megan shrugged "We're still working on the Disney movies." She replied, of course Luke had only been born a week and he did live in a house full of girls.

Clyde rolled his eyes. "I'm coming over this weekend and we're watching every Star Wars."

"Okay." Luke agreed cheerfully.

Maria pushed Clyde towards the door. "I'll walk you to the bus stop. Bye guys." She waved dragging Clyde downstairs with her.

Sarah Jane and Fiona went upstairs.

"I almost put you guys in danger. I should have guessed it was aliens." Sarah Jane shook her head.

"I messed up too. I gave them the equation." Luke said as Alison flung her arm around him.

"Yeah, but you didn't really. You only thought you did." Alison pointed out.

"Besides we may have a normal last name, but we are from normal with a mother that investigates aliens and a little brother that was created by aliens." Megan laughed.
