Scott was getting ready for bed. As he laced up his lacrosse stick, he heard an odd sound. He grabbed a wooden bat and made his way outside.

Stiles dangled from the roof, causing Scott to scream.

"Stiles, what the hell are you doing?!" Scott cried, noticing Molly. "Who's she?"

"You weren't answering your phone," Stiles replied. "Why do you have a bat? This is Molly. I picked her up on the way. She's new to town."

"I thought you were a predator."

"A pre -- I -- wha -- look, I know it's late, but you gotta hear this. I saw my dad leave 20 minutes ago. Dispatch called. They're bringing in every officer from the Beacon Department, and even State Police."

"For what?"

"Two joggers found a body in the woods."

"A dead body?"

"No, a body of water. Yes, dumbass, a dead body."

"You mean like murdered?"

"Nobody knows yes. Just that it was a girl, probably in her late 20s."

"Hold on, if they found the body, then what are they looking for?"

"That's the best part. They only found half. We're going."

Molly looked between the boys, focusing on Stiles. "It's alarming how excited you are about half a dead body."

---

Scott let out an annoyed sigh as they reached the Beacon Hills Preserve. "We're seriously doing this?"

"You're the one always bitching that nothing ever happens in this town," Stiles shot back.

"I was trying to get a good night's sleep before practice tomorrow."

"Right, 'cause sitting on the bed is such a grueling effort," Stiles replied sarcastically.

"No, because I'm playing this year. In fact, I'm making first line."

"Hey, that's the spirit. Everyone should have a dream, even a pathetically unrealistic one."

Molly rolled her eyes before asking, "Just out of curiosity, which half of the body are we looking for? Oh, if either of you see two tall men in plaid, hide me. They'll kill me dead if they see me out here."

"Huh! I didn't even think about that. Kill you dead? Who says things like that?"

"I do."

"And, uh, what if whoever killed the body is still out there?" Scott wondered.

"Also something I didn't think about," Stiles admitted.

Molly glanced at Scott and asked, "Is this common?"

Scott nodded. "It's basically a daily occurrence that Stiles has a plan with little detail."

"Huh. It's a wonder you two are still alive."

Stiles shot her a look as Scott said, "It's comforting to know you've planned this out with your usual attention to detail."

"I know," Stiles replied.

"Maybe the severe asthmatic should be the one holding the flashlight, huh?" Scott suggested, pausing.

Molly glanced back and Scott ushered her forward.

"Wait, come on!" Stiles cried as Molly caught up to him.

"Stiles! Wait up! Stiles! Stiles!"

"Hold it right there!" a cop demanded.

"Hang on, hang on. This little delinquent belongs to me," Sheriff Stilinski said, grabbing Stiles' collar. "Who's your friend, Stiles?"

"Dad, how are you doing?" Stiles asked innocently.

Dean narrowed his eyes. "What the hell are you doing out here, Molly? It's a school night."

Shit. Molly smiled sweetly. "I'm exploring my new town."

"Coincidence. We're gonna have a talk about sneaking out, young lady."

"So, do you, uh, listen in to all of my phone calls?" Sheriff Stilinski asked.

"No, heh," Stiles replied. "Not the boring ones."

"Now, where's your usual partner in crime?"

From behind the tree, Scott froze, hoping he wouldn't get caught.

"Who, Scott? Sc - Scott's home. He said he wanted to get a good night's sleep for first day back at school tomorrow. It's just me and my new friend Molly. In the woods. Alone." He took her hand and she yanked her hand away and swatted his head. "Ow!"

"Scott, you out there? Scott? Well, young man, I'm gonna walk you and Molly back to your car. You're gonna take her to the Argent home. I'll give you the address. And you and I are gonna have a conversation about something called invasion of privacy."

Sheriff Stilinski did as he said and the teens got into the Jeep.

Stiles dropped Molly off at the address his dad had given him and said, "See you tomorrow."

"Mhmm," Molly hummed.

Molly knocked on the front door and it opened.

Chris Argent smiled and said, "You must be Molly. Your brothers mentioned you'd be coming."

"Half-brothers," she corrected.

"My apologies. Come on in."

A woman with short red hair, Victoria, stepped into the foyer and said, "Hello, Molly. Allison is upstairs, if you'd like to meet her."

"Yeah, sure."

The blonde walked up the stairs and a brunette appeared and said, "You must be Molly. I'm Allison."

"Nice to meet you. Mind showing me where I'm sleeping? I'm pretty exhausted."

"Uh, sure." She led Molly to a guest room. "In here. There are extra towels and sheets in the closet directly across the hall."

"Thanks."

Allison nodded and left with a smile.

Molly dropped her stuff on the floor and sat on her bed.

A knock on the door sounded and the door opened to reveal Dean.

Dean crossed his arms and asked, "Why were you in the woods, Molly? And don't bother lying to me."

Molly stared at him as she said, "I was looking for half a dead body with that boy. I met him and he let me join him."

Dean glanced back and closed the door before walking closer to Molly. "Do you know why we're here?"

Molly shook her head slowly. "Hunter friends?"

"Werewolves are rumored to be here and we need to see whether that's true or not."

"If there are werewolves-"

"Molly, let me and Sam handle this, okay? Your job is to go to school."

"I'm as much a hunter as you and Sam! Stop treating me like a little kid!"

"I need you safe, Molly! If there are werewolves in town, the woods are dangerous at night. Promise me you'll listen."

"But Dean-"

"Promise me, Molly."

Molly nodded and mumbled, "I promise."

"What was that?"

"I said I promise."

"Good. I'm gonna hold you to that. Get some rest. You've got a busy day ahead of you." He left and Molly glared at the door.

---

The next day at school, Scott pulled up on his bike just as Jackson Whittemore opened the door of his Porsche.

"Dude -- watch the paint job," Jackson protested.

"Yo, Jackson, let's go, bro," Danny called.

"Okay, let's see this thing," Stiles told Scott who lifted his shirt. "Ooh!"

"Yeah," Scott agreed. "Whoa! It was too dark to see much, but I'm pretty sure it was a wolf."

"A wolf bit you?" Molly repeated with a frown.

"Uh-huh."

Stiles shook his head. "No, not a chance."

"I heard a wolf howling."

"No, you didn't."

"What do you mean, no, I didn't? How do you know what I heard?"

"Because California doesn't have wolves, okay? Not in like 60 years."

"All right, well, if you don't believe me about the wolf, then you're definitely not gonna believe me about when I tell you I found the body."

"You -- are you kidding me?"

"No, man, I wish. I'm gonna have nightmares for a month."

"Oh, God, that is freakin' awesome. I mean, this is seriously gonna be the best thing that's happened to this town since -- Since the birth of Lydia Martin. Hey, Lydia -- You look -- Like you're gonna ignore me. You're the cause of this, you know."

Lydia glanced back, seeing Molly, and motioned her over.

Molly shrugged and walked up to the strawberry blonde. "Yeah?"

"I haven't seen you around before," Lydia said. "Who are you?"

"Molly. I take it you're Lydia Martin. Stiles was just talking about you."

"Who?"

"The boy with the buzz-cut. Didn't you notice him?"

"He's not in my inner circle, so no."

"Well you're rude," Molly mumbled.

"What'd you say?"

"I said oh okay then."

Lydia raised a brow and looked Molly up and down. "I can't tell if you're going for farmer or casual hippie."

"This is my normal clothing. Gotta go." She ran off and muttered, "God, aren't you bitchy."

Molly made her way to the front office and was given her schedule.

Allison smiled when she saw Molly. "You left pretty quickly this morning. My dad would've given you a ride."

Molly smiled tightly. "I get myself where I need to go."

"Is everything okay? You don't seem happy."

"I just- Never mind. Everything's fine."

"Okay." She glanced at her phone. "My dad wants to tell me something. I'll be back."

The vice principal walked up after Allison had returned and walked them to their first class.

Allison and the vice principal were talking, but Molly tuned them out.

---

In an English class, the teacher said, "As you all know, there indeed was a body found in the woods last night. And I am sure your eager little minds are coming up with various macabre scenarios as to what happened. But I am here to tell you that the police have a suspect in custody, which means you can give your undivided attention to the syllabus which is on your desk outlining this semester."

The vice principal walked into the room with Allison and Molly. "Class, these are our new students, Allison Argent and Molly Winchester. Please do your best to make them feel welcome."

"Thanks," Allison and Molly said.

"We'll begin with Kafka's Metamorphosis, on page 103," the teacher said.

---

The bell rang and Molly made her way to her locker. She began fiddling with the combination and yanked it open.

Lydia walked up to Allison, whose locker was next to Molly's, and said, "That jacket is absolutely killer. Where'd you get it?"

"My mom was a buyer for a boutique back in San Francisco," Allison replied.

"And you are my new best friend. Hey, Jackson."

A girl asked, "Can someone tell me how new girls are here all of five minutes, and they're already hanging out with Lydia's clique?"

"Because they're hot," Stiles said, staring at Lydia before glancing at Molly. "Beautiful people herd together."

"So, this weekend, there's a party," Lydia informed. "And yes, Molly, I'm making you go."

"A party?" Allison and Molly repeated.

"Yeah -- Friday night," Jackson told them. "You two should come."

"Uh, I can't," Allison lied. "It's family night this Friday. Thanks for asking."

Molly shook her head. "I don't do parties."

"You two sure?" Jackson asked. "Everyone's going after the scrimmage."

"You mean like football?" Allison questioned.

"Football's a joke in Beacon. The sport here is lacrosse. We've won the state championship for the past three years."

"Because of a certain team captain," Lydia replied, kissing him.

"Well, we have practice in a few minutes. That is, if you don't have anywhere else-"

"Well, I was going to-" Allison began.

Lydia smiled. "Perfect -- You're coming."

---

The girls made their way to the field.

The boys ran onto the field and Allison noticed Scott. "Who is that?"

"Him?" Lydia questioned. "I'm not sure who he is. Why?"

"He's in my English class."

Molly glanced at the brunette. "That would be Scott McCall. I met him l- this morning."

"Hey, way to catch with your face, McCall!" Jackson taunted.

"He seems like he's pretty good," Allison noted.

"Oh, very good," Lydia agreed.

"Something happened last night," Molly mumbled. "What the hell was it?" Maybe there really were wolves in California after all.

---

After lacrosse practice, Molly followed Scott and Stiles, wanting to figure out what was going on with Scott.

"God," Scott said. "I don't -- I don't know what it was. It was like I had all the time in the world to catch the ball. And that's not the only weird thing. I-I can -- hear stuff I shouldn't be able to hear. Smell things."

"Smell things?" Stiles repeated. "Like what?"

"Like the mint mojito gum in your pocket and the peppermint chapstick in Molly's."

"I don't even have any mint mojito--" Stiles pulled out said gum while Molly instinctively patted the pocket carrying the chaptstick. "So all this started with a bite."

"What if it's like an infection, like, my body's flooding with adrenaline before I go into shock or something?"

"You know what? I actually think I've heard of this -- it's a specific kind of infection."

"Are you serious?"

"Yeah. Yeah, I think it's called -- lycanthropy."

"What's that? Is that bad?"

"Oh, yeah, it's the worst. But only once a month."

"Once a month?"

"Mm-hmm. On the night of the full moon." He howled, earning a look from Scott. "Hey, you're the one who heard a wolf howling."

"Hey, there could be something seriously wrong with me."

"I know! You're a werewolf! Rrr! Okay, obviously I'm kidding. But if you see me dragging Molly to shop class trying to melt all the silver we can find, it's 'cause Friday's a full moon."

"No, I-I could have sworn this was it. I saw the body, the deer came running. I dropped my inhaler."

Molly let out a sigh. "Well maybe the killer moved the body. Scott, if you really are a werewolf, you need to be careful. My half-brothers are good hunters. And when I say good, I mean two of the best."

Scott glanced at her. "If he did, I hope he left my inhaler. Those things are like 80 bucks. Hunters? What the hell are you talking about? I'm not a werewolf."

"I said if you were. But to be honest, I'm worried Stiles' comment wasn't actually a joke."

"What are you doing here?" a dark-haired man demanded. "Huh? This is private property."

Molly pulled out her silver knife and stood in front of the boys, intent on protecting them from the man in case he proved to be dangerous. Scott and Stiles tried pulling her back, but she refused to budge.

"Uh, sorry, man, we didn't know," Stiles apologized from behind Molly as he lowered the arm she was holding the knife in.

"Yeah, we were just looking for something, but -- Uh, forget it," Scott said. "Uhm. All right, come on, I gotta get to work."

The man tossed Scott his inhaler and he caught it. The dark-haired man walked away.

"Dude, that was Derek Hale," Stiles told his friend. "You remember, right? He's only, like, a few years older than us."

"Remember what?" Scott asked.

"His family. They all burned to death in a fire, like, ten years ago."

"I wonder what he's doing back."

"Come on."

---

After school the next day, Stiles grabbed Molly's arm as she passed his Jeep.

Molly frowned. "What?"

"I need your help. You seem to know a lot about werewolves and we need talk to Scott."

"I know a little about a lot. Just enough to make me dangerous."

"Right. Look, the werewolf thing is real. You were right. And a wolf killed that body in the woods. They found the animal hairs."

"Okay. You drive, I'll text Scott. Where are we meeting?"

"My house."

"Okay. Uh, wait. I need Scott's number."

Stiles gave her the number and as he drove, Molly sent a text to Scott. 'Got your number from Stiles. Get to his house ASAP'

Scott knocked on Stiles' bedroom door and Stiles pulled him in. "Get in. You gotta see this thing. I've been up all night reading -- websites, books. All this information."

"How much Adderall have you had today?" Scott asked.

"A lot. Doesn't matter. Okay, just listen."

"Oh, is this about the body? Did they find out who did it?"

"No, they're still questioning people, even Derek Hale."

"Oh, the guy in the woods that we saw the other day."

"Yeah. Yes. But that's not it, okay?" Molly said. "Just listen."

Scott frowned. "What, then?"

"Remember the joke from the other day?" Stiles questioned. "Not a joke anymore. The wolf -- the bit in the woods. I started doing all this reading. Do you even know why a wolf howls?"

"Should I?"

"It's a signal, okay? When a wolf's alone, it howls to signal its location to the rest of the pack. So if you heard a wolf howling, that means others could have been nearby. Maybe even a whole back of 'em."

"A whole pack of wolves?"

Molly shook her head and met Scott's eyes. "No -- Werewolves."

"Are you two seriously wasting my time with this? You two know I'm picking up Allison in an hour."

"I saw you on the field today, Scott," Stiles said. "Okay, what you did wasn't just amazing, all right? It was impossible."

"Yeah, so I made a good shot."

"No, you made an incredible shot, I mean -- The way you moved, your speed, your reflexes. Y'know, people can't just suddenly do that overnight. And there's the vision and the senses, and don't even think I don't notice that you don't need your inhaler anymore."

"Okay! Dude, I can't think about this now. We'll talk tomorrow."

"Tomorrow?" Molly repeated. "No. The full moon's tonight. Don't you get it?"

"What are you two trying to do? I just made first line. I got a date with a girl who I can't believe wants to go out with me, and everything in my life is somehow perfect. Why are you two trying to ruin it?"

"Because you're a half-dog, half-human and there will be hunters after your ass!" Molly yelled. "Sam and Dean don't know you're a werewolf yet. At least I don't think so. But it's only a matter of time before they find out."

Stiles pulled her back as he said, "We're trying to help. You're cursed, Scott. You know, and it's not just the moon will cause you to physically change. It also just so happens to be when your bloodlust will be at its peak."

"Bloodlust?"

"Your urge to kill," Molly explained.

"I'm already starting to feel an urge to kill, Stiles, Molly."

"You gotta ear this," Stiles begged. ""The change can be caused by anger or anything that raises your blood pressure." All right? I haven't seen anyone raise your pulse like Allison does. You gotta cancel this date. Molly and I are gonna call her right now."

Molly began rifling through Scott's bag and pulled out his phone.

"What are you doing?" Scott demanded.

"I'm cancelling the date," Molly replied.

"No, give it to me!" Scott yelled as he shifted slightly.

He scratched the chair and held Molly against the wall, an arm under her throat.

Molly tried pushing him away and quickly pulled out her silver knife. "I will use this."

"I'm sorry," Scott apologized. "I-I gotta go get ready for that party. I'm sorry."

"Right. You're sorry. Back the hell up."

Molly massaged her neck and picked up the desk chair. She frowned and studied the scratches. "Hey, Stiles. Look."

Stiles glanced at the scratches. "I think we're in way over our heads."

"No, you are."

"I guess. Um, can I take you to Lydia's party?"

"Do I really have to go?"

"Everyone's gonna be there. Lydia's parties are awesome."

"Yeah, uh, she insulted my clothes, so we're not exactly besties."

"Oh. Well, you can stick with me if you want."

"I guess so."

---

They made their way to the party and danced a little before they noticed Scott acting weird.

"You okay?" Allison asked.

"What? Yeah. I'm fine," Scott replied.

"Are you okay?"

"I'll be right back." Scott walked away.

Stiles called out after his friend, "Yo, Scott, you good?"

"Scott!" Molly said.

Molly ran after Stiles just in time to see the Jeep driving off. "Stiles! Seriously? Are you kidding me?!"

Allison walked up. "You got left behind too? What's going on with Scott?"

Molly shook her head and lied, "I have no idea."

Derek walked up to the girls. "Allison. Molly. I'm a friend of Scott's. My name is Derek."

Molly narrowed her eyes slightly. "Don't try any creeper shit. I know how to shoot and stab."

Derek nodded, amused by her threat. "I'll keep that in mind."

SCOTT'S HOUSE

"Go away," Scott said, hearing a knock on his bedroom door.

"Scott, it's me," Stiles told him. "Let me in, Scott. I can help."

"No! Listen, you gotta find Allison and Molly."

"They're fine, all right? I saw them get a ride from the party. They're -- they're totally fine, all right?"

"No, I think I know who it is."

"You just let me in. We can try-"

"It's Derek. Derek Hale is the werewolf. He's the one that bit me. He's the one that killed the girl in the woods."

Stiles' face fell at the thought that the new girls could be in danger. "Scott -- Derek's the one who drove Allison and Molly from the party." He heard a crash. "Scott!"

Stiles drove to the Argent home and knocked on the door. A woman with short, red hair answered and Stiles began rambling. "Hi, Mrs. Argent. Um -- You have no idea who I am. I'm a friend of your daughter's and Molly's. Uh -- Look, this is gonna sound kind of crazy, um -- Really crazy, actually. You know what? Crazy doesn't even describe-"

"Allison! Molly! It's for you," Victoria Argent called.

Molly and Allison appeared at the top of the stairs looking angry.

Stiles had seen some angry looks in his day, but Molly's might have topped them all. She looked both angry and upset, both of which gave her a scary devastating expression.

WOODS

"Where are they?" Scott demanded.

"They're safe," Derek said. "From you."

"What did you do with them?"

"Shh, quiet. Too late. They're already here. Run."

Scott was shot in the arm and Chris Argent said, "Take him."

Derek pulled Scott to safety and Scott asked, "Who were they?"

"Hunters," Derek replied. "The kind that have been hunting us for centuries."

"Us? You mean you! You did this to me!"

"Is it really so bad, Scott? That you can see better -- Hear more clearly, move faster than any human could ever hope? You've been given something that most people would kill for. The bite is a gift."

"I don't want it."

"You will. And you're gonna need me if you want to learn how to control it. So you and me, Scott -- We're brothers now."

Sam glanced at his brother and said, "I don't think these are the werewolves we want."

Dean frowned. "Are you serious? Dude, they're monsters! We kill monsters."

"And the teenager seems to be one of Molly's new friends. Are you gonna kill her friend?"

"If I have to, yes."

"She won't forgive you if you do that."

"She'll come around."

"I doubt it."

---

The next day at in the Jeep, Scott said, "You two know what actually worries me the most?"

"If you say Allison, I'm gonna punch you in the head," Stiles warned. "And Molly may hit you." He glanced at her. "She looks like she wants to. Or maybe she wants to punch me. Or both of us. I can't tell."

"She probably hates me now."

Molly shook her head. "I doubt that. But, you're going to need to come up with a pretty amazing apology. Stiles already owes me one."

"Ugh," Stiles groaned. "I doubt that. Like Molly suggested, you might want to come up with a pretty amazing apology. Or, you know, you could just -- Tell her the truth and -- Revel in the awesomeness of the fact that you're a frickin' werewolf. Okay, bad idea. Hey, we'll get through this. Come on, if Molly and I have to, we'll chain you up ourselves on full moon nights and feed you live mice. I had a boa once. I could do it." He glanced at Molly. "I'm sorry for abandoning you and Allison at the party last night. And I'm glad you're safe."

Molly nodded slowly. "Just don't let it happen again."

"I don't plan on it."

---

At school, Allison walked up to Scott. "So what happened? You left me and Molly stranded at the party."

"Yeah, I-I know," Scott admitted. "I'm really sorry, I am. But -- You're gonna have to trust that II had a really good reason."

"Did you get sick? Molly said you weren't feeling well."

"I definitely had an attack of some kind."

"Am I gonna get an explanation?"

"Can you just find it in your heart to trust me on this one?"

"Am I gonna regret this?"

"Probably. So is that a yes on a second chance?"

Allison smiled. "Definitely yes." A car caught her attention. "That's my dad. I better go." She skipped to the car.

Scott looked at the man waving and realized it was Allison's father who had shot him the night before. He noticed two tall men behind them car.

Molly saluted to Sam and Dean and Scott walked up to her and said, "You know them?"

"Yeah. They're my half-brothers," Molly replied.

"They were in the woods with Allison's father last night."

"I won't let them kill you. Sam I can reason with. Dean will be harder, but I'll figure something out."

"Thanks."

"You're my friend. I won't let Sam or Dean kill you. I promise."
