Chapter 1 - The Bullet

Erin had returned to Beacon Hills after splitting with her boyfriend, she had been home two weeks. Everything was going well with her until she got a call from her brother's friend. That was how she knew something was off. Stiles sounded panicked as he rambled on about something to do with poison. Several moments after talking with him-trying to make sense of what he was saying-she agreed he should meet her at work and then before she knew it, Stiles and a man she had never met before were standing in front of her in the animal shelter. Erin's blue eyes widened at the sight of the man. He was definitely older than Stiles. He looked like he was her age, but something about him seemed beyond years. His jet black hair was tousled and his eyes were wild. Overall, he looked like he was in pain.

Stiles gestured to Derek who sat on the pile of dog biscuits. "Erin, this is Derek. Derek, this is Scott's sister, Erin."

"Stiles?" she exclaimed before continuing, "What the hell is going on here?" However, she got neither answer nor a glance in her direction. Erin crossed her arms over her chest in annoyance. Unbelievable, she thought.

"Does Nordic Blue Monkshood mean anything to you?" Stiles asked Derek reading from his phone.

"It's a rare form of wolfsbane," he said with a heavily sigh. "He has to bring me the bullet"


"Because I'm gonna die without it" Derek summarised trying to maintain a menacing glare.

"Ok, what the hell is going on? Bullets and dying?" Erin interrupted.

"I promise you we will explain everything you just have to help us" Stiles promised.

"Help you do what? I don't understand what's going on here" Stiles and Derek didn't seem to care; they just walked past her and into the examination room. The room gave off cold air, causing the hairs on her arm to stand up. Erin rubbed her arms to try to warm them as she glanced around the medium-sized room. Her eyes finally settled on the boys including a-now-shirtless Derek. She had to admit, his body was well built. She could tell he must have worked out a lot, but that wasn't important right now. Her throat tightened when she caught sight of his swollen arm. It looked completely abnormal. The veins were even begging to protrude from under his skin.

"You know that really doesn't look like anything a bit of aspirin and a good night's sleep wouldn't cure" Stiles told him. Typical Stiles; always joking around.

"Stiles" Erin warned him with my eyes, she could tell this was serious.

"What?" he held his hands in the air trying to look innocent.

"I really don't think this is the time to be joking" Erin stated the obvious to him as Derek laid his arm on the metal table and looked at the wound. After she had asked the older male what he needed her to do, Derek took a deep breath and was looking worse by the minute. "If the infection reaches your heart…" she began to say.

"It will kill me," Derek finished the sentence for her as he looked at her for what she thought was the first time. Before now, it seemed like he hadn't noticed her.

"Positivity just isn't in your vocabulary is it?" Stiles asked. Erin swore that boy was always looking to piss someone off.

Derek seemed to ignore him and began looking through various draws and cabinets "If he gets here in time, you need to get the powder out of the bullet, set it on fire, and then rub the remains in the wound, you got that?" Derek looked at Erin, she nodded, he handed her a lighter "if he doesn't get here with the bullet in time, as a last resort"

"Which is?" Stiles enquired

"Your gonna cut off my arm" Derek concluded holding up a saw staring straight at Stiles.

"Whoa," Erin interjected, quickly moving in front of Derek. "I'm guessing Stiles bought you here because for some reason you can't go to a hospital and right now I don't want to know, but you can't cut off your arm!"

"You're a vet, right?" Derek asked. "You can stop the bleeding after."

"There's a problem with that. I am a vet," Erin emphasized. "Vet, as in animals, so unless you're about to sprout a tail and some paws you're shit out of luck with me"

"Careful what you wish for," Stiles remarked then quickly shut up when she gave him another look. Derek stepped around Erin and leaned on the table. Erin thought the table was the only thing holding him up as she left the room to get some supplies she thought she might need.

Derek placed the saw on the table and slid it across to Stiles; he picked it up and switched it on. He looked like he was about to throw up. Derek began tying something around his arm. "What if you bleed to death?"

With the thing in his teeth Derek replied. "I'll heal if it works"

Stiles really started to look like he was about the vomit "Look, I don't know if I can do this"

"Why not?"

"Well cause of the cutting through the flesh, the sawing of the bone and especially the blood"

"You faint at the sight of blood?"

"No but I may at the sight of a chopped off arm!" Erin re-entered the room carrying gauzes and bandages.

"Alright fine" Derek began but had to stop to take a few breaths "how about this. Either you cut off my arm, or I'm gonna cut off your head"

"Alright I'm really so not buying your threats any..." Stiles didn't get to finish what he was saying Derek grabbed him the collar of his shirt. "Alright ok"

"Hey" Erin shouted and pushed Derek off of Stiles "touch him again and it won't be your arm you've got to worry about" she threatened, she waited a few seconds for it to sink in, for dramatic effect. Derek leant over the side of the table and threw up, black stuff.

"What the hell is that?" Stiles asked

"My body trying to heal it self" Derek told him.

"Well it's not going a very good job of it"

"Shit, Derek sit down before you fall down" Erin told him taking his good arm to help lead him to the floor.

"Now, we gotta do it now" Derek told them.

"I can't watch this" Stiles admitted as Erin picked up the saw.

She put the saw to Derek's arm and hesitated "Just do it!" Derek yelled.

"Give me a damn second" Erin took a deep breath and was about to count to three when she heard Scott call Stiles' name. Her brother's voice was the best sound she had ever heard in that moment.

"Scott," Stiles said as Scott came in to the room.

"Did you get it?" Erin asked, putting down the saw. Scott took a bullet from his pocket and handed it to Derek. "What are going to do with it?" She asked looking at it like everyone else was.

"I'm gonna, I'm gonna…" Derek began, the bullet dropped from his hand and Erin had just enough time to catch him and ease him to the floor, the last thing he need was to add concussion to his list of aliments.

Stiles began to freak out and kept repeating for Erin to do something. The bullet had rolled down the drain; Scott was trying to get it back. "Derek," she said as she shook him. "Derek come on wake up." She slapped his face slightly, he deserved it, dying or not he shouldn't have threatened Stiles. "Scott, can you get it?"

"I don't know," he said, his voice strained. Scott was trying harder. "I can't reach it"

Erin checked Derek's pulse, it was faint but there. "He's not waking up. What do we do?"

"You're the doctor," Stiles moaned

"No Stiles, I'm a freaking vet!"

Stiles stood over Erin and Derek. "I think he's dead" Stiles stated

"He isn't dead, he's passed out"

"I got it, I got it" Scott shouted excitedly standing up with the bullet in his hand.

"Give it to me," Erin told Scott standing up. "Stiles try and wake him up." Erin tried getting the tip of the bullet off but it was too tight. Scott snatched it from her and bit the end off before he passed it back. She tapped the bullet on the table and got out the powder and used Derek's lighter to set it on fire.

"Please don't kill me for this," Stiles said before punching Derek in the face. It worked. Derek stood up as Erin scooped the ash in to her hand. He stood beside her and she pushed the ash into his wound. The young beta had begun to yell in pain and fell to the floor again.

They watched as he withered in pain then like magic, the wound and the veins disappeared- his arm was normal again. "That was the coolest thing I've ever seen." Stiles summarized.

Derek sat up at the exact moment that Scott crossed the room. "Are you okay?"

"Expect for the agonizing pain," Derek retorted.

"Guessing the ability to use sarcasm is a good sign of health," Stiles remarked

Derek looked at him like he was about to kill him. "Ok, ok. Anyone care to explain?" Erin thought they had forgotten she was in the room.

"It's a long story," Scott began looking at Stiles, Stiles subtly shook his head but she saw it, clearly this was some big secret, "I'll tell you tomorrow"

"Oh, I get it," Erin began getting things to clean up the black stuff Derek had thrown up, "you need time to cook up a story with Stiles so you can lie to me."

"No," Scott protested, "I wasn't going to lie"

"Whatever bro, you know you've been acting weird for a while now. I'll just chalk it up to that," Scott began to talk but she spoke over him. "I'm tired and I need to clean this place up can you all just leave."

"Erin," Scott started knowing she was pissed off. "I promise I'll explain"

"Go home, Scott. I'm not in the mood for this"

"I can help tidy the place up…,"he started, but Erin held her hand up to quiet him.

"Please Scott, just go. Stiles take him home."

"What about Derek?" Stiles asked

"I'll get myself home," Derek assured Stiles whilst he put his shirt back on. Scott and Stiles left together and Derek followed shortly after.

Erin pulled up outside her house; it had been a long night and she couldn't wait to crawl into her bed and sleep. She walked up to her door looking for the keys in her bag as she climbed the first two steps. Right before she was about to put the key in the lock, she jumped when she spotted something in the corner of her eye. "Shit! Are you trying to give me a heart attack?" Erin asked.

"No," Derek answered in that serious tone that never appeared to leave his voice.

"Well, I apologize. We must have different meanings of the word heart attack," Erin assessed.

Derek stepped out of the shadows. "I wanted to say thank you for helping me. A guy you don't know and your brother's friend show up and ask you to chop off an arm; anyone else would have called the cops, so thanks"

Erin wasn't expecting a "thanks" so soon so she was completely off guard. Erin smiled, "You know I thought the same to myself. I think I'm slightly unhinged"

A smirk hung on his lips. "Who isn't nowadays?"

Erin nodded "true" and then there was a moment of silence. "So, was that all?"

"I want to explain the situation to you the truth, but it isn't simple."

Erin became defensive "Make it simple. Is Scott in trouble?"

"No," he answered before correcting himself. "Yes."

"Which is it?"

"Yes," He was silent again

"It's Derek, right?" He nodded. "Derek, I've had a hell of a day, even before you showed up on Death's door and are now miraculously perfectly fine. Either you tell me and stop talking in riddles or leave and let me get some sleep"

"I'll come here tomorrow at noon," Derek told her. "We'll explain together"

"Thank you, I appreciate it, but if I hear one thing I think is a lie," she pointed a warning finger at him.

He held his hands up as if surrendering. "I promise no lies. Just not sure how much you'll believe"

"Great another riddle. Night Derek," Erin unlocked the door and entered the house.
