Principal Celestia's son.
Day One: The Nightmare Begins.
"Again girls I just can't thank you enough." Principal Celestia said to the seven girls in on her front porch. The seven girls on the porch just brushed off the compliments.
"It's no problem." Sunset Shimmer said. "But can you remind us why can't your sister take care of him again?"
"Because she'll be gone all week at ComicCon." Principal Celestia said. "If you need anything don't hesitate to give me a call."
"I'm pretty sure we'll be fine." Rainbow Dash said confidently, "Don't worry about the tyke's safety."
"Oh it's not his safety I'm worried about." Celestia said. "It's yours." She then grabbed her rolling suitcase and hefted it into the trunk of her Toyota Corolla. She got in the driver seat and waved. "Bye girls~"
The girls turned and entered the two story and looked around and saw... nothing. It looked pretty regular. "Where are all the kids toys?" Rainbow asked.
"What did you expect Rainbow?" Applejack asked.
"I dunno, something more like a kid." Rainbow admitted looking around.
"Well then you would be wrong." A new voice added, the girls heads swiveled in the direction of the voice. What they saw shocked them, it was a boy around their age maybe even older he had short brown hair and was in his pajamas, plus he had a little stubble of hair growing around his face. Standing around 5'7 he was leaning on the bannister of the upstairs ledge that overlooked the living room. "So she sent Seven people to look after me this time. Quite a dramatic change, but first lets get introductions out of the way. My name is Johnathan, you can call me John, now if you're wondering why you've never seen me around Canterlot high, that's because I graduated college when I was around 13."
"Hi, John. Principal Celestia never said that you would be..."
"As old as you girls?" He finished for them.
"Yeah..." Rainbow Dash trailed off.
"There are drinks and food in the fridge do what you want. I'm going to be in the backyard smashing a junk car with a very big hammer." John said as he put a sledgehammer on his shoulder and walked down the stairs and out the back door.
"He seems very..." Twilight offered.
"Strange?" Sunset said.
"Erratic?" Rarity
"Off?" Fluttershy mumbled.
"Different." AJ and Dash said together.
"I think he could be lots of fun." Pinkie said and the girls looked at her. "What? I'm just trying to be positive."
The girls out of curiosity decided to follow the boy, and he was doing exactly what he said. He was using a sledgehammer to smash a car. John was busy smashing in the back window of the old clunker, in fact the scene playing out in front of the girls was very strange. There were tools and other objects surrounding the car and it seems that he made very little effort in destroying it. There were spray paint cans scattered over the lawn, there was a shovel sticking out of one of the wheels and the one of the doors was duct tapped to the roof of it. The smell, that was something else. It smelled like a port-a-potty had hate sex with vomit and their rage baby had taken a shit on the lawn. The girls were confused at the sight of the teenage boy. Then Fluttershy tapped Rarity's shoulder and pointed to somewhere else in the backyard. There was a sculpture, made out of car parts and the like; Rarity then pointed it out to the other girls and they looked around to see that he wasn't pointlessly destroying things. He was making art, then there was a loud bang and a voice yelling out. "FUCK!" The girls turned their attention to John who was now occupied with hopping around on one foot while holding the other.
Fluttershy's caretaker instincts leapt into action and she was over there in an instant. "Are you alright?"
"Yeah I think I'll be fine." John started to hop to the stairs of the porch, then he sat down and looked at his foot. "Well I think that's enough destruction for one day. That's going to bruise like a bitch though."
Rarity then smacked John in the head. "Such language. I'm sure your mother raised you better than that."
"It's my house I can say what I want when she's not around." John replied and then got up. "I was getting bored of doing art anyways." John walked back inside and went down into the basement. The door of the basement had a sign that said The Game-Room and the girls followed once more. When they reached the bottom step the room opened up and revealed arcade cabinets, a pool table, a hockey table, and area for console games as well. There was also a guitar with amps set up in one corner and a jukebox in the other. The girls were absolutely slack-jawed.
"How can Principal Celestia and Vice-Principal Luna afford all of this?" Twilight asked.
"They can't, but I can." John said as he grabbed his guitar and started to strum a few notes.
"You play guitar?" Rainbow asked.
"Yeah." John said while playing a few chords. "Why?"
"I play too." Rainbow said. "You're not so bad though."
"Can you play Through the Fire and Flames by Dragonforce?" John asked.
"No..." Rainbow though admitted to herself that that was badass.
"How do you afford all these things?" Rarity asked.
"Those sculptures you saw in the back yard were only a few of my collection, my pieces fetch from 5 to 10 thousand each. Though one of them sold for like 50 thousand." John said.
"Wow you must be very good." Fluttershy said.
"Nah, it's just a hobby that puts money in my pocket." John said. "I have a lot of hobbies. It keeps me busy."
"Why don't you just work?" Applejack asked.
"I'm not good with people." John said. "In fact this is the nicest I've been to anyone."
"Doesn't that get kinda sad?" Pinkie asked.
"Not really, my brain functions on a way different scale than the average person." John said. "Basically my brain is a Ferrari that is always going at top speed and never runs out of gas."
"Then why not try to learn more?" Twilight asked.
"It'd be a waste of time, well to me anyways." John started to quietly play a song. "I don't like to continue my education when it's something I'm not going to like. The things I do around here I like to do they keep my mind busy."
"So then what do WE do?" Sunset asked. "We were asked to keep an eye on you."
"It's not really to keep an eye on me, but to make sure that I have company and that I won't do anything stupid. Besides that, go nuts. Just don't break my shit, and don't touch Damien."
"Who or what is Damien?" Rarity asked.
"Let's hope you never have to find out."
