After washing all (most) of the rainbow coloring out of Derek's hair, Stiles left the cabin to give Derek a bit of peace and quiet. Stiles told Derek he was going to accompany the adults on their hike, and that Derek didn't have to go. He didn't want to, what he wanted to do was go and get back at the idiot kids who ruined his masculinity.

DEREK

He slowly left the cabin, wearing only his boxers and a white tank top. He would take those off later when he was in secret.

Stalking through the dark campground felt amazing, like he was a kid again, and that anything was possible. It almost felt like he was a teenager again, running around from tree to tree and scratching the Hale family crest in every one of the thick brown trunks. His mother was furious, but Derek and his brothers and his sisters and his cousins and Peter thought it was the best night of their entire lives, just being kids and running around causing trouble. That night was one of the few nights he really felt like a kid, not a beta werewolf with responsibilities and duties and an entire pack at home to scold him if he did something wrong.

When he smelled Doug (it amazed Derek that his scent was so pungent he found him in an instant), Derek shifted into alpha form and willed his bones to crack and rearrange into a big black wolf, like his mother had been able to change into when he was a child. He ran around to the front of the cabin and scratched the door.

Inside, he immediately heard Brailee wake up. Perfect

He unleashed a loud snarl that progressed into a howl. Brailee's fear spiked and she screamed. That woke up Doug, who tried his hardest to calm down his frightened girlfriend. Derek started to slam his body against the door, growling like a rabid animal. For a minute he forgot what he was supposed to be doing, only scaring the teenagers in the cabin. His eyes went blood red, and his thoughts went from scare to kill. Bite. Tear.

Before he could completely break down the door, Stiles ran over and screamed "STOP, OH MY GOD, WHAT THE HELL ARE YOU DOING?!"

Derek was about to turn and pounce when he suddenly caught Stiles' scent. Home. Pack. Mate,his brain told him, causing Derek to snap out of it. He shifted back to human, crouching there naked on the floor, his head turned to Stiles. He wanted to say something, do something, but all he could hear in his mind was mate. Mate. Mate. Mate.

"Derek whatever-the-fuck-your-middle-name-is Hale, what in the ever living FUCK did you just do?! You're damn lucky I missed the adults and all the kids are watching a movie in the lodge, or you could have been seen and found out by my entire family! Who the fuck did you just try to kill?!"

Derek was stunned silent. Why had his wolf form registered Stiles as his mate? Why did the word mate even come to mind? He wasn't an animal, dammit, he was human, he had girlfriends and someday he would have a wife, not a mate. And even if he did have a mate, it wouldn't be Stiles. Stiles was fragile and pliable and easily broken (pretty much any synonym for "weak little bitch" was a good word to describe Stiles). And human. Don't forget human.

"-and howling and I woke up and he was slamming on the door!"

He looked over at Brailee and Doug and Stiles, the younger two behind Stiles. Stiles was standing protectively in front of them, his scent giving off a vibe of "fuck you, I'm not scared of you".

Derek stood up and Doug covered Brailee's eyes, his own wide and lingering on Derek's manhood. Doug said something to Stiles, causing Stiles to cringe. He covered Doug's eyes and yelled at Derek. "WHAT THE HELL WAS THAT ALL ABOUT?!"

"I... I..." Derek was lost for words. He didn't know what that was all about. He was just as confused as Stiles. Doug peeked between Stiles' fingers and whimpered. "Is this why you were all up in my shit at the lake yesterday?" he asked meekly, almost a squeak. "You thought I smelled weird, because you're a werewolf?"

Derek slowly nodded, looking apologetically at the three teenagers before him. He didn't bother covering himself up, his pride was already far enough down the drain for it to bother him.

"I'm disappointed in you. Really fucking disappointed," Stiles said, leading Brailee and Doug back into their cabin. Derek grabbed his tank top and boxers, walking back to his cabin. If he had a tail right now, it would be between his legs. He was so embarrassed and mad at himself and confused. Stiles had smelled like pack. Like home. It calmed Derek, soothed his wolf. Just Stiles being there made Derek feel safe and happy and calm. He couldn't shake what he was feeling.

Stiles is mate. Stiles is pack. Stiles is home, he heard in the back of his mind. He sighed and went back to the cabin. Before he even had the chance to get dressed and go to sleep, he strained his hearing back toward the cabin. All he could hear was Stiles, saying in a reassuring voice, "Don't worry, I'm not in his pack."

Derek's wolf howled and whined inside him, clawing to get out and go tell Stiles he wasn't just his pack, he was his mate. Derek repressed the wolf, holding back the urge and collapsing onto the bed. He fell asleep as soon as his head hit the pillow.

STILES

The whole camp was deserted, every able adult on the night hike and every unable adult/child was watching Monsters Inc. in the lodge. Stiles was about to go inside the lodge to watch with them before he heard a howl. An ear-splitting heart-stopping howl. One he recognized immediately as Derek. He bolted to his cabin, looking inside for the alpha.

Derek was nowhere in sight, but before he could even get back out the door, he heard a girl scream far off in the campground. He gasped and bit his lip, running toward where the scream was.

He ran into a huge black wolf, with bright red eyes focused on the cracking, splintery mess of a door he was crashing into repeatedly. It was Derek, Stiles could tell, by the faded tips of some patches of fur. They were rainbow, like the dye in his hair had been.

Stiles was frozen for a second before screaming at the top of his lungs, "STOP, OH MY GOD, WHAT THE HELL ARE YOU DOING?!"

Derek turned and crouched, ready to launch himself at Stiles. Stiles gasped and raised his hands, ready to at least try and defend himself when Derek tried to rip his face off. But it didn't happen. He looked at Derek again and he was sort of just... Mesmerized. His eyes were half closed and his nostrils flared, in the middle of a deep inhale. A tiny whine escaped Derek before he shook his head wildly, eyes turning normal Derek green and widening. He stared at Stiles, all 185 pounds of perfectly toned and sculpted werewolf sitting naked on the front porch of a cabin.

"Derek whatever-the-fuck-your-middle-name-is Hale, what in the ever living FUCK did you just do?! You're damn lucky I missed the adults and all the kids are watching a movie in the lodge, or you could have been seen and found out by my entire family! Who the fuck did you just try to kill?!"

Stiles realized Derek wasn't listening and fearlessly sidestepped the older man, throwing the door open. Inside, Brailee was curled up in her Hello Kitty pajamas, sobbing against Doug's chest. Stiles grabbed them both and dragged them outside, right past where Derek was still sitting dumbfounded.

"Brai, what happened?" Stiles asked his cousin softly, wiping her cheeks.

"Doug and I were sleeping, we just finished talking and hanging out and we fell asleep. I was almost asleep but I heard scratching on the door so I assumed it was a fox or a coyote or something so I brushed it off. Then I heard snarling and howling and I woke up and he was slamming on the door!"

Stiles pushed the two behind him and looked down at Derek. He tried his hardest to look tough and brooding, but in reality he was about as scary as Casper the friendly ghost.

Derek stood, his trouser snake hanging loud and proud for all to see. Doug took no time in covering Brailee's eyes, but couldn't seem to look away himself. "Damn, can't believe you take that in the ass bro," he said calmly, eyes still locked on Derek's joystick. "That's gotta feel amazing, and I'm not even gay!"

Stiles almost gagged, but he didn't think that would make Doug's mental image of the two of them any better. He cringed instead and yelled at Derek. "WHAT THE HELL WAS THAT ALL ABOUT?!"

Derek stuttered for a reply, but couldn't seem to choke out a word. Stiles felt his fingers part and Doug choke out "Is this why you were all up in my shit at the lake yesterday? You thought I smelled weird, because you're a werewolf?"

Derek nodded, looking pathetic and sorry. Stiles tried to ignore it and make Derek feel like he was in deep trouble.

"I'm disappointed in you. Really fucking disappointed," he said darkly, glaring daggers at the werewolf. He took Doug and Brailee back into the cabin. purposefully bumping into Derek on the way. He closed the door, sighing and sitting on the bed. Brailee piped up softly. "Wait... Your boyfriend's a werewolf?"

Stiles almost wanted to say he's not my boyfriendbut even he knew that was a terrible idea. Brailee was a pretty bad tattler, she would get them kicked out in an instant. She was good at keeping secrets though...

"Yes, he's a werewolf. He's a werewolf and he has a pack back home in Beacon Hills."

"Are you a werewolf too?" Doug asked, eyes wide.

"No. Don't worry, I'm not in his pack. Well, actually I kind of am. I'm their token human. I'm what's called an Emissary. Well, I'm more of a surrogate Emissary. You have to be a Druid to be considered a real Emissary. At least, I think that's how it works."

Brailee's eyes widened. "I'm really confused. Can I be an Emissary?"

Stiles just shook his head. "You don't want to tangle with werewolves. I got roped into it because my friend Scott got bitten by Derek's uncle, Peter. But Peter's not really his alpha, Scott's his own alpha, but don't tell Derek. Derek is one hundred percent convinced that Scott is a beta in his pack. It's really complicated and boring and dumb and pretty much a huge boiling pot of nonsensical mystical magic bullshit."

"How many Emissaries are there?" Doug asked.

"Well, I know three. Knew three. Knew two, know one. I knew Julia Baccari, and my guidance counselor, Ms. Morrell. And I know Dr. Deaton, the Emissary to Derek's family. But he kind of quit after the Hale's house and family burned down. I took his place."

Nodding slightly, Brailee said "The two girls died?"

A laugh escaped Stiles before he could stop it. "Well, I don't know if one of them is actually dead. But yeah, one of them I'm positive is dead. Remember all those murders a while ago? And the disappearances? That was Julia, disguised as Jennifer Blake, she took on the Darach, an evil dark magic sacrificial asshole that almost killed my dad and Scott's mom and our friend Allison's dad."

"Man, that's crazy." Doug commented, curling his long legs up to his chest. "Is Derek gonna go insane and try to kill us again?"

Stiles stood and went to the door. "You know, he probably only did that because you ticked him the fuck off. It's no one's fault but your own."

With that, he left, storming back to his cabin. He and Derek needed to talk.
