I have no excuse except that I'm a sadistic and slightly masochistic bastard... especially if I stick to my plan for this.

Preschool

Derek was already the strange, quiet kid and the first day of preschool hadn't even officially started yet. While all the other kids cried, clinging to their mothers and/or fathers, Derek let go of his mother's hand and walked right up to the teacher. He stared up at her expectantly until she awkwardly gestured to the door behind her. His face broke into an adorably toothy smile as he walked passed her in the direction of the door.

After a brief struggle getting the heavy door open, he turned and waved goodbye to his mother. She was smiling brightly as she waved back. He knew then that he would miss her all day but she was the one that had insisted he go to preschool so he would go and try to enjoy it like she had told him to.

He looked around at the other children. He knew they were just acting out because they would miss their mothers and fathers too. It didn't take long for him to notice several sets of eyes were locked on him. Some of the other parents, particularly the ones with screaming children, were watching him with strange or unreadable expressions on their faces. His smile faltered seeing so many people staring at him.

"Derek," his mother called softly, pulling his attention back to her. She gave him two thumbs up, still smiling, as she said "Have a good day, baby."

His smile came back in full and he waved again before he walked into the classroom. The door swung shut behind him, cutting him off from the teacher and the rest of the class. He was the only one in the room so he did what any kid his age would do when they had free run of a place, he ran around, touching things.

The room smelled mostly of cheap air fresheners that weren't that offensive to his sensitive nose but certain parts of the room, mainly over near the toy shelves, smelled of detergents and something harsher like bleach. He wrinkled his nose when he got too close to the gross smell. He wouldn't be playing with those toys.

After a few minutes, he found a crate of red cardboard bricks that didn't smell too offensive. He dragged the crate over to a secluded corner of the room where he would be out of the way and that bad smell was weakened.

By the time the teacher came in with the other kids he was safely hidden behind a high wall of the cardboard bricks. His small backpack was propped up to block the space between where he had run out of the bricks and the wall. Timber, his stuffed wolf, sat atop his backpack, keeping guard as Derek silently played with the little green and brown toy soldiers he had insisted his mother pack for him alongside Timber.

He tried his hardest to ignore the other children when his sensitive ears picked up on some of them whispering about him. Maybe building a wall around a space only big enough for one person hadn't been the best idea but he was scared of the other children. His older sister, Laura, had warned him that other kids could be mean for no reason, especially when they knew another kid was different.

He was different by birth but that wall really didn't help.

The last remaining brown soldier had just shot the last green soldier, ending the bloody battle between werewolves and hunters— werewolves victorious of course— when someone crashed through his wall. A boy landed in front of him in a pile of fake bricks and toy soldiers Derek hadn't been fast enough to save. Derek sat there, stunned, with the only 'living' werewolf soldier clutched tightly to his chest.

Instead of crying, the boy started laughing hysterically, pausing for only a few seconds to screech "Oh my god! Your face!"

Derek looked up from the laughing boy to the rest of his classmates. Everyone was staring straight at him, their eyes comically wide with… fright. The teacher turned to see what everyone was looking at, as soon as she saw him she dropped her coffee mug, both hands shooting up to cover her gaping mouth.

He didn't understand why everyone was staring at him like he was the weird one. It was obvious that the weird one was the other boy who was still lying in the pile of cardboard bricks, laughing so hard he was crying.

"D-Derek," The teacher said timidly, pulling his attention back to her from where it had drifted to the weird boy in front of him. "I need you to come here, sweetie."

Derek's stomach twisted into uncomfortable knots, he didn't like the way she or the rest of the class was staring at him. His chin started to tremble so he bit his lower lip to stop it. That was when he felt them. His pointy teeth were bigger than normal, long and sharp. He looked down at his hands and saw claws instead of fingernails. He had been so frightened that he had accidently shifted. This wasn't the first time it had happened to him but it was the first time around people other than his family.

He got up, grabbing Timber and his backpack. He was pretty sure he would be sent home for scaring the other kids. His mother would be so disappointed in him. Tears burned at the corners of his eyes as he walked over to his teacher. His classmates all scrambled to get away from him if he got too close to them. He stopped in front of the teacher, head down.

She knelt before him and tilted his chin up so he had to look at her face. A couple of tears escaped when he blinked but she wiped them away before the other kids could see him crying and tease him about it. She was smiling warmly at him when her pointy teeth became bigger and sharper and her dark eyes glowed golden. Derek sniffled but smiled. She was a werewolf too.

"Okay?" She asked softly, taking his hands and squeezing them reassuringly.

"Yes, ma'am," He said, smiling faintly when he realized he hadn't had to try to talk around a mouth full of fangs. His gaze shot down to their hands and sure enough he had fingernails instead of claws.

She stood up and ruffled his soft hair. He smiled brightly at her and was right about to thank her when she called out the weirdest name he'd ever heard.

"I told you to call me Stiles!" An annoyed boy's voice cried out.

Derek turned to see that weird name belonged to the boy who had ruined his wall. He was still sitting in the pile but had stopped laughing by now. He had a firm frown on his pale face as he stared at the teacher. A Batman action figure was peeking out from the pocket of his red hoodie.

The teacher let out an aggravated sigh and beckoned the boy over, "Stiles come here."

The boy, Stiles or whatever his real name was, got up and walked over to stand beside Derek, his attention was fixed on the teacher. "Yes?"

Derek looked him over and blinked when he saw his eyes, they were molten gold. For a moment he got his hopes up that there may be another werewolf, one his age, in class. However, the excitement faded when Stiles looked at him and the gold didn't fade, just shifted shades. His eyes were naturally golden. He was human. Derek frowned, disappointed.

"Apologize to Derek for knocking his wall down," The teacher ordered.

"I'm sorry I knocked down your wall," Stiles said grudgingly then looked up at the teacher who smiled down at the two. He waited for her to walk away before he turned back to Derek and continued in a hushed voice, "but it was stupid and you really shouldn't have built it in the first place. It was weird. You cut yourself off from the rest of us like a weirdo. You were making yourself out to be a weirdo. No one likes weirdoes so I actually did you a favor by knocking it down. You should be thanking me not making me say sorry for helping you, weirdo."

Derek stared wide eyed at the kid who talked faster than those salesmen on the TV. He didn't realize the only reason Stiles had stopped talking was because he was waiting for Derek to actually thank him. It clicked when the boy cleared his throat and tapped his foot on the tiled floor.

"I'm not saying thank you to you, you scared me and you're mean." Derek protested and crossed his arms.

Stiles rolled his eyes, "Well, sorry but the big bad wolf isn't supposed to be scared of little red riding hood."

"You just called yourself a girl," Derek pointed out with a small smile.

Stiles' jaw dropped, "Little red riding hood can be a boy!"

"But she isn't," Derek said, biting his lip to keep from laughing at the face Stiles was making.

Stiles opened his mouth to say something but then shut it and flailed his arms out of frustration, "Ugh. Fine. Touché"

"What's that mean?" Derek asked, tilting his head a little.

"I don't know but my daddy says it a lot when my mommy wins an argument he started," Stiles explained with a shrug.

"Is that your Batman?" Derek asked, pointing to the action figure still peeking out of Stiles' pocket.

Stiles looked down at it and took it out. He grinned before launching into an animated, mostly one-sided conversation about how Batman is the best superhero ever.

After that Derek and Stiles were practically inseparable. They partially rebuilt the wall so it looked like a wall in a ruined city and were playing werewolves and hunters against Batman and Timber. Derek went from playing silently by himself to screaming sound effects and orders to retreat over Stiles' own sound effects and screams to attack. The werewolves and hunters were getting trampled.

"Stiles?" "Derek?"

Both boys instantly looked up from the bloody battlefield to see their mothers standing over them. They stared at their mothers for a few moments then they returned to the bloody battle at hand.

"It's time to go home," Stiles' mother said in a soft, fond voice.

Derek frowned at that and looked at his own mother who nodded in agreement. With a sad little sigh he started to pack up his soldiers.

Stiles wasn't so obedient. He crossed his arms and stared up at his mother defiantly. "Mom! No! Batman was just about to defeat the hunter army and save Timber from the werewolves at the same time!"

"That sounds very exciting but your Dad is waiting for us," Stiles' mother said in a firmer voice.

Stiles was clearly about to protest when Derek's mother added "You two can pick up where you left off tomorrow."

That seemed to do the trick because Stiles jumped to his feet and grabbed his own mother's hand, yanking on it. "Really?! We get to come back tomorrow?"

His mother just nodded and a huge grin lit up his face like he was just told Christmas came early this year. He looked at Derek and practically screamed "We get to come back tomorrow!"

"Yep," Derek smiled back at him.
