[2x09; Party Guessed]

Olivia slipped into the abandoned train station, clutching a coffee and the large file she put together to her chest. Making her way through the turnstiles, past the waiting area, and onto the platform, she stumbled her way down to the stairs that would lead her to the car that Derek and Isaac shared. It didn't surprise her when Derek slipped out of before she could enter, shrugging on a shirt with fluffy morning hair.

"What are you doing here so early, Ollie?" he yawned.

"I found something. Here," she handed him the coffee.

Derek quickly downed a large gulp, not even grimacing from the scalding liquid. "What'd you find?"

"Information," Olivia wandered over to the dirty table they kept and sat down, opening the file. "I spent the last week researching and putting together a timeline of all these abilities. "

"From when Peter bit you," Derek nodded, taking the seat across from her.

"Yeah, they first showed up when Lydia escaped from the hospital," Olivia pulled out her timeline and pushed it over to him. "and then again on the day of Isaac's first full moon, when Erica knocked out Stiles, when the kanima trapped you two in the pool…"

Derek read through the instances she could remember. "And these were all the times your eyes turned purple?"

Olivia nodded. "Every single time, someone I cared about was in danger."

"Your pack," Derek stated. "Not just your actual pack but the people you consider pack, too, like Jackson and Lydia."

"Exactly," Olivia confirmed. "And Stiles had told me that there were a few supernatural creatures with purples eyes. There were a couple of options; fairies, pixies, anchorams, and dragons."

"I think it's safe to say you're not a dragon."

Olivia smiled weakly. "So, I looked at the other options. Fairies and pixies didn't fit any of the abilities I've been having, so I narrowed it down to anchorams."

"Anchorams," Derek hummed thoughtfully. "Did you get anything on them?"

Olivia shook her head. "There wasn't a lot on the internet, so I looked in the Argent's bestiary."

"What'd you find?"

Olivia pulled out the pages she had Lydia help her translate. There wasn't a lot in the Argent bestiary, either, but there was enough to get a reading on what she actually was.

"Anchorams, otherwise known as anchors, are caretakers of the pack," she read. "A sub-species of werewolf, the anchor knows when a member of their pack is in danger or injured. If the anchor is powerful enough, they will fall into a fugue state and find the pack member in distress."

"Anchorams' eyes glow purple when their powers are being used," she continued. "The most helpful of an anchors' powers are their ability to calm werewolves with their touch or voice."

Olivia set down the paper and looked back at Derek for a reaction. His expression was blank but his there was a hint of emotion in his eyes that she couldn't quite make out. The longer he didn't respond, the more anxious she got. She knew Derek would accept her, because he had already done so despite the fact that she didn't turn into a werewolf, but it was still nerve-wracking.

Despite the fact that it took her months to figure out what she was, she was so relieved now that she actually knew. The stress of not knowing was weighing her down and it kind of felt like she could breathe again. Now that she knew what she was, she could train and use her abilities to help Derek, her pack, and her friends.

"It makes sense," Derek said finally.

Olivia raised her eyebrows. "It does?"

"Yeah," he nodded. "Ollie, on Isaac's first full moon, you almost completely calmed him down before I stepped in. From what he said, you did it when he broke into Scott's house as well."

Olivia cocked her head thoughtfully. "I guess…"

"And you were doing it before you were even bitten," Derek pointed out. "When Scott had first changed, your voice would calm him down a little. When Cora—when you and Cora were kids, she was always much calmer with you by her side."

"So, I've been this my entire life," Olivia bit the inside of her cheek. "and Peter biting me, what, accelerated my powers?"

"Yeah, I guess so," Derek confirmed. "but this is good news, Ollie."

"Why?"

"Because now that we know what you are, we can train you."

Olivia pressed her lips together and nodded. She was thinking the same thing and it was nice to know that Derek would have her back. The Hale family was mostly gone but at least Olivia and Derek had each other.

Olivia and Derek went through the rest of the research she had, even though most of it was irrelevant, through the rest of the morning. Isaac woke up an hour after she arrived and Boyd and Erica arrived an hour after that so the pack could go over the plan for the full moon that night.

Originally, Olivia hadn't been part of the plan for the full moon for her safety and the fact that it was Lydia's seventeenth birthday. Now, the plans had changed; Olivia would spend an hour or two at Lydia's party and then come back to the train station to help with Isaac, Erica, and Boyd.

Now that they knew she had abilities to calm the new betas down during their transitions, they knew that had to take advantage of that.

Derek pulled out a trunk with the triskele branded on the front, opening the hatch to reveal numerous lengths of chain.

"What is that?" Isaac pointed at the triskele.

"It's a triskele," Olivia told him. "Spirals can mean different things—past, present, future. Mother, father, child."

"For Hales, it means something different," Derek added. "What do you think it is?"

"Alpha, beta, omega?" Boyd spoke up.

Derek nodded at him. "That's right. It's a spiral," he started to explain further. "It reminds us that we can all rise to one or fall to another."

"Betas can become alphas but alphas can also fall to betas or even omegas," Olivia stated.

"Like Scott?" Isaac wondered.

Derek shook his head. "Scott's with us."

"Really?" Isaac looked around as though he was searching for Scott. "Then where is he now?"

Olivia rolled her eyes at the hostility Isaac was showing. It was like he was feeling threatened now that Scott had joined the pack to take down Jackson.

"He's looking for Jackson," Derek informed him. "Don't worry, he's not gonna have it easy tonight, either. None of us will. There's a price you pay for this kind of power; you get the ability to heal but tonight, you're gonna want to kill anything you can find."

"Good thing I had my period last week, then," Erica commented with pursed lips; Olivia sent her an amused grin.

Derek shook his head and picked up a metal band that fit around the head with numerous nails that could be adjusted. He walked over to Erica and presented it to her. "Well, this one is for you."

Olivia grimaced, not envying Erica at all.

Stiles stared down at the yearbook in front of him, his eyes narrowing at the picture of Kara Simmons, the rave promotor that Jackson had killed. She didn't fit the pattern of the rest of the victims; sure, she was twenty-four and had been in the same graduating class but she hadn't been part of Harris' class that the rest of the victims shared. It was infuriating that he couldn't figure out why Kara had been killed.

He wanted this kanima bullshit to be done already. Too many people were getting hurt and the pack was still floundering on how to stop Jackson without killing him dead.

"Hey, whatcha doing?" Noah came up to his door while he was flipping to the next page.

"Homework."

As Noah walked away Stiles went onto the next page of the yearbook, finding nothing that was useful.

"It's spring break," Noah was back; he entered Stiles' room and sighed when he saw the yearbook on his desk. "What do you think you're doing?"

"Oh, I'm just satisfying my own curiosity," Stiles said nonchalantly. He went to turn another page but his dad reached over and closed the yearbook.

"We brought Harris in this morning for questioning," he informed Stiles before correcting himself. "They brought him in."

Stiles eagerly turned to Noah. "And?"

"And they're working on a warrant to arrest him for the murders."

"For all of them?"

"Enough of them."

Stiles raised his eyebrows. "With what proof?"

"You remember the couple at the trailer?" Stiles nodded at Noah's question. "Tire tracks nearby match Harris' car."

"W-What?" Stiles shook his head and opened the yearbook back up. "That's not enough."

Noah closed the yearbook again. "The same car was also seen outside the hospital where the pregnant wife was killed," he sighed. "It's got some bumper sticker on it, a quote from Einstein?"

Well, that rang a bell.

"What quote?" Stiles wondered.

"Something about imagination and knowledge."

Okay, so Harris' car was at the rave, too, then. "Imagination is more important than knowledge," he quoted with a nod. "Yeah, I saw the same car parked outside the rave."

"That means you're a witness," Noah pointed out. "You're gonna have to give a statement."

Stiles couldn't spend time on that. There were more important things. "But what about the concert promoter, Kara?" he asked, thinking of the break in the similarity of victims. "She wasn't in Harris' class, right? I mean, what does Mr. Lahey have to do with Harris?"

"It doesn't matter," Noah stressed. "The tire tracks put Harris at the site of three murders. That's damning evidence."

Stiles shook his head firmly, opening the yearbook once again. "No, that's not enough."

Noah sighed and let him look through the book. "I thought you hated this guy."

"I don't hate him, all right? He hates me," Stiles corrected him as he continued to look through the book. "And, you know, if he killed them all, then yeah, lock the psycho up but there's something missing."

"Hey. Hey," Noah grabbed Stiles' attention. "You don't have to solve this for me."

"I have to do something," Stiles sighed; he couldn't just wait around and not be useful. Since he couldn't do the same stuff as Scott and Derek, then he could do this. He looked back up to his dad and saw that Noah was staring down at the yearbook with narrowed eyes. "What?"

"Look at the swim team."

Stiles looked down at the page, his eyes going straight to the team picture. All of the victims; the mechanic, Argent's hunter, the rave promoter, and the couple were all squished together to smile at the camera. And then, at the bottom of the page, was a picture of Mr. Lahey.

"Dad, the coach," Stiles pointed out quickly. "It's Isaac's dad."

Olivia went through the numerous dresses that Lydia had bought for her party. They were all very cute and all something that both she and Lydia would wear. It didn't surprise her that her cousin went overboard, too, since there were at least five dresses.

"So," she turned to Lydia with a smile. "which one is your host dress?"

Lydia grinned and picked out the bodycon dress with black and gray stripes. "This one," she set it down and picked up a dark blue dress. "and this will be the evening dress."

"What, no after-hours casual?" Olivia joked, earning a laugh from Lydia. "Did you talk to Jackson?"

Despite the fact that Lydia knew that Jackson was the kanima, she still wanted him at her birthday party. Lydia had gone to the school after lacrosse practice was finishing up and had spoken to Jackson personally to make sure he was still going.

"Yeah," Lydia confirmed. "and he was acting weird."

Olivia furrowed her eyebrows. "Weird, how?"

"Like how you told me he was at the rave," Lydia sighed; Olivia nodded worriedly. "Anyway, I touched his arm for a second and he seemed to snap out of it."

"Did he?"

Lydia nodded. "And he told me that I didn't want him at my party," she hesitated for a second. "Liv, do you think he knows what's going on with him and he was warning me or something?"

"Maybe," Olivia crossed her arms over her chest, frowning. "As much as I want to say that it's good that he knows what's going on, now, I don't think it's better for him."

"Because now he knows he's being controlled," Lydia supplied, thinking along the same lines as Olivia. "and there's nothing he can do to stop it, either."

Olivia bit the inside of her cheek; she hated this whole thing. People were dead because of whoever was controlling Jackson and Jackson had no way to stop it. Despite the fact that Jackson was a dick, he didn't want to kill people. Now, all that blood was on his hands even though it wasn't really his fault. It had to be heartbreaking for him. He didn't deserve to be someone's murderous slave.

"Damn it," Lydia sighed, tears welling up in her eyes.

"It's gonna be okay, Lyds," Olivia tried to assure her; she didn't feel confident, though. "We're gonna find whoever is controlling Jackson and we're gonna stop him."

Lydia gave her a sad smile. "I hope so," she sniffed two times before perking up, changing the subject. "So, I got you a romper since you'll be going to help Derek and his pack."

"Are you sure you're okay with that?" Olivia asked Lydia as she grabbed one of the Macy's bag and pulled out a black romper that was actually really cute. "I can stay, if you want me to."

Lydia paused as she rearranged the romper on her bed and gave Olivia a stern look. "Liv, you have the power to help Isaac, Erica, and Boyd," she reminded her. "I would be the world's biggest bitch if I told you I didn't want you to go."

"No, you wouldn't," Olivia disagreed.

"Uh-huh," Lydia rolled her eyes. "Now, I want you to try this on before we start setting up."

Olivia shook her head in amusement, grabbing the romper and heading to the bathroom she shared with Lydia.

Hours later, Lydia party was set up. Olivia had been in charge of the decorations and music, making sure everything was set up to Lydia's standards, while Lydia was in charge of the food and drinks. The food was simple finger foods that Natalie ordered from a caterer before she slipped away from the house to give them space, while the punch was a recipe that Lydia saw on Pinterest.

A couple of people had arrived already, including Allison and Scott, but there wasn't as many people as there usually was at one of Lydia's parties. It was positively bare compared to what Olivia was used to and she could tell that it was bringing Lydia down.

While Lydia was making sure there was enough punch poured for the partygoers, Olivia was assigned the front door. Fifteen minutes after the party started, the doorbell rang once again. When she opened the door, she came face-to-face with Stiles, who was holding a huge box in his arms.

"Hey!" he greeted her enthusiastically, shaking the present.

"What on Earth," Olivia's eyes trailed over the box, which was wider than he was. "What did you even get her?"

"A teddy bear," Stiles answered simply. "Okay, I'm coming in."

Stiles didn't get very far. The present was too wide for the door frame, which meant that he couldn't get it in right away. Olivia watched him with a smile as he struggled for a few seconds, trying to forcefully push the box through the door.

What a dork, she thought to herself fondly.

"You know you can just flip it around, right?" she pointed out, gesturing so it seemed like she was flipping the box vertically.

Stiles stopped struggling and gave her an annoyed look. "You couldn't have said anything earlier?"

"I figured you knew!" Olivia grinned.

Stiles rolled his eyes fondly. "You're so mean to me," he flipped the present like Olivia said and easily walked through the door. "but you're beautiful so I don't mind."

Olivia's heart fluttered but she didn't respond to his comment. "The present can go there," she pointed at the present table, where only four packages laid. "and Lydia made the punch so make sure you get some of that."

"Will do," Stiles nodded, setting the present down at the table. "Is Scott here?"

"Yeah," Olivia confirmed. "and so is Allison but they're on separate sides of the backyard."

"Right," Stiles clicked his tongue. "So, is Jackson here yet?"

"Not yet. Why?"

"Well, I found something out while I was going through the 2006 yearbook," Stiles told her. "All the victims were on the swim team and Mr. Lahey was the coach."

Olivia looked at him in surprise as they started heading toward the backyard. "Are you serious?" Stiles nodded. "Okay, so this all has to do with water, then, right?"

"That's what I think," Stiles agreed. "Remember the way the kanima reacted to water?"

Olivia nodded. "So, whoever's controlling the kanima hates the 2006 swim team."

"Yep and I thought that it may be another teacher but what if we're missing something?"

They stepped out into the backyard, where the party of five was taking place. Lydia was still waiting by punch table on one side of the pool, while two random people were dancing by the stereo, and Allison and Scott were talking quietly with each other.

"I'll guess we'll have to figure it out," Olivia put a comforting hand on Stiles' arm for only a second but it seemed to relax him.

Allison and Scott approached them, each with their own hesitant smiles. Olivia guessed that there was still some awkwardness between them from their fight at the rave the previous week.

"Uh, Jackson's not here," Allison pointed out needlessly.

"Yeah," Stiles' eyes flittered over the empty backyard. "No one's here."

"Maybe it's just early," Scott offered weakly.

Olivia shook her head. "The party started almost twenty minutes ago."

"Nobody's coming because Lydia turned into the town whack job," Stiles commented before backtracking when Olivia frowned at him. "Uh, I mean…yeah, it's pretty early."

Olivia rolled her eyes while Allison spoke up. "Well, we have to do something," she declared. "because we've completely ignored her for the past two weeks."

That's true, Olivia thought to herself, Scott, Stiles, and Allison had really talked to Lydia since Derek tried to kill her.

"She's completely ignored me and Stiles for the past ten years," Scott shrugged, unbothered. "We don't owe her a party."

"Okay, well, she wouldn't be the town whack job if it wasn't for all of us," Olivia pointed out; Peter had bitten Lydia and the rest of them had lied to her about what was going on. "So, if we could please do something."

Scott sighed and looked over at Lydia, who looked uncomfortable with the lack of people. "I guess I could use my co-captain statue to get the lacrosse team here."

"Yeah, I also know some people who can get this thing going," Stiles pulled his phone from his jeans. "Like, really going."

Allison frowned at him. "Who?"

"I met them at the gay club when Jackson was trying to kill Danny," Stiles informed them. "Let's just say they know how to party."

The people who Stiles met at the gay club were drag queens and they were some of the nicest people that Olivia had ever met. With them and the lacrosse team and their girlfriends showing up, the party was actually exciting.

Olivia played her part as co-hostess and answered the door to let everyone in but when the doorbell stopped ringing, she allowed herself to join the party. She didn't usually like parties but it was Lydia's birthday and she wanted to have fun before she had to go deal with out-of-control baby werewolves.

She hung out with Lydia for a while, pointing out the people that Stiles invited because her cousin had no idea who they were, listening to the music that pumped through their backyard, and eating cake. Eventually, Lydia went off to pass out some more punch and Olivia went to find Stiles.

Olivia didn't like dancing in public but the last time she did, she was with Stiles and she had a lot of fun. And she had romantic feelings for Stiles now, and she didn't see a point in hiding them forever. Stiles had told her that he had feelings for her long before she realized her own and they had just shared a kiss—even if it was an absentminded one.

"Hi," she approached him with a smile; he lit up when she stopped in front of him. "Are you having fun?"

"Yeah!" Stiles nodded jerkily, sipping on his punch. "What about you?"

Usually Olivia would play it cool; she'd be casual as she answered him and she wouldn't let on that she was enjoying his company. Not this time. "Do you wanna dance?"

Stiles raised his eyebrows in surprise. "You want to dance?" she nodded. "Are you feeling okay, Livvy? I mean, I practically had to drag you out onto the dance floor last time."

"Yeah, well," she shrugged with a small smile. "I like dancing with you."

Stiles' jaw dropped for a second but it was like Olivia's words gave him a boost of confidence. He quickly set his punch down on the nearest table and firmly grabbed Olivia's hand, twirling her around before pulling her into his arms.

"Wow," Olivia breathed, surprised, as his hands drifted down to her hips while they swayed to the music. "and here I was thinking that we'd be doing the chicken dance again."

"The chicken dance is fun but I like this, too," Stiles grinned at her. "You look amazing, by the way."

"Thanks," Olivia squeezed his biceps. "I like when you wear green."

"You do?!"

"Yeah," she assured him, her smile widening. "but I like blue on you the best."

"Oh," Stiles perked up excitedly. "Well, that's good because my favorite color is blue."

"Really?" Olivia asked in surprise; she would have thought it was red or something. "Why?"

Stiles stared into her cobalt-blue eyes. "Blue is pretty."

Olivia's heart melted right then and there.

Olivia shifted uneasily on her feet from where she stood next to Isaac, watching as Derek chained Boyd and Erica up in the back of the train car. All three of the newbie betas were uneasy as the full moon got closer but it was really a struggle for Erica and Boyd. It was their first full moon, so they all were expecting them to act out of control tonight. Isaac would have a better chance but from how tense he was, he was in for a rough night, too.

This full moon felt different than the last for Olivia, too. She didn't know if it was because she was actually aware of the powers she held this time but she could feel the moon starting to affect her. Not in the way that it did for werewolves, it was like the exact opposite. She felt more in control than ever, like her body knew that she had a purpose and she would be fulfilling it tonight while helping Erica, Boyd, and Isaac stay in control.

"What if we break free?" Boyd asked as Derek finished chaining him up.

"Then you'll do anything you can to get out of here," Derek answered him. "You'd probably try to kill me and Olivia, then each other, and anything else with a heartbeat."

"Hopefully I'll be able to help you with your control so that doesn't happen," Olivia gave him a small, reassuring smile; Boyd returned her smile with a trusting nod.

Derek moved onto to the chains restraining Erica. He quickly made sure they were going to hold her before picking up the headband he had showed her that morning. He looked to Isaac and Olivia and nodded back at Erica, "I need you guys to hold her."

Isaac immediately took Erica's arms behind her back while Olivia laid both of her hands on her shoulders. "So," Isaac wondered. "how come she gets to wear the headband thing?"

"Because she'll be able to withstand more pain than the two of you," Derek set the metal headband on top of Erica's head and slipped it down, making sure it was over her forehead. "I've got an extra one if you really want it."

Olivia grimaced and looked over at Isaac, who quickly shook his head. "I'll pass."

Derek looked to Erica. "You ready?"

"Yeah."

As a pack, they all took a deep breath together. Derek started twisting the prong into the skin of Erica's forehead; Erica screamed loudly, fighting against Isaac's hold on her. Olivia held onto her shoulders as tight as she could, but even she felt unsettled with the slight tingling in the same spot on her forehead.

It was hard for everyone to hear Erica's painful screams. At first, it was just the prongs of the headband causing them but then the moon came out and it was all part of her transition. Boyd soon joined her, grunting and groaning while trying to break free of the restraints holding him.

Olivia restrained Isaac while Derek watched over Boyd and Erica. As soon as she was done, they'd switch places and Olivia would take a crack at trying to be an anchor for them.

"How doesn't Derek feel this?" Isaac murmured as she clasped a handcuff around his wrist and tightened the one holding him to the seat.

"I'm sure he feels every second of it," Olivia looked up at him. "He's had more practice, though."

"That's how he controls it?"

"He has an anchor. It's something meaningful to you. You can bind yourself to it and keep your human side in control," Olivia straightened to her full height and glanced briefly at her cousin as he spoke with his betas. "For Derek, it's anger, but it doesn't have to be for everybody."

"Like Scott?"

"Yeah," she confirmed, knowing that Allison was Scott's anchor. "but listen, if you can't find an anchor tonight, don't worry about it. We can work on it," she placed a hand on his shoulder and he visibly relaxed. "It's why I'm here."

Isaac nodded quietly. Erica screamed again, catching Olivia's attention. "Tell me if you need help," she told Isaac before making her way back to Erica and Boyd. "All right, let's do this."

Stiles was officially bored of Lydia's party. The party itself was still hopping, with dozens and dozens of people drinking Lydia's spiked punch, dancing, talking to their friends, and swimming in the large pool. It was fun but not for Stiles.

He was almost positive it was because Olivia had split a half-hour before. Their dancing had been interrupted by birthday cake and after Lydia blew out the candles, Olivia told him she had to leave to help Derek with Isaac, Erica, and Boyd. He didn't know exactly how she was supposed to help keep three new betas in control but it figured it had something to do with the way her eyes turned purple on the last full moon.

So, now he was stuck next to a stubborn-ass Scott, who kept on sending Allison puppy-dog eyes without realizing it.

"Are you gonna apologize to Allison or what?" he asked his best friend, taking a sip of punch from his plastic cup.

Scott gave him a confused look. "Why should I apologize?"

"Because you're the guy. It's, like, what we do."

"But I didn't do anything wrong."

"Then you should definitely apologize," Stiles glanced back at Allison, where she was chatting with Lydia, and then back to Scott. "See, any time a guy thinks he hasn't done anything wrong, it means he's definitely done something wrong."

Scott thought about that for a moment before insisting, "I'm not apologizing."

Stiles pressed his lips together and gave him a knowing look. "Is that the full moon talking, buddy?"

"Probably," Scott shrugged. "Why do you care, anyway?"

"Because, Scott, something's gotta go right here. I mean, we're getting our asses royally kicked, if you haven't noticed," Stiles pointed out firmly. "People are dying, I got my dad fired, you're gonna be held back in school and if, on top of all that, I gotta watch you lose Allison to a fucking stalker like Matt, I'm gonna stab myself in the face."

As he finished, he was surprised to realize that there actually was something going right in his life. His relationship with Olivia was progressing every day. It almost made up for everything else going bad—almost.

"Don't stab yourself in the face," Scott was staring across the pool. "Jackson's here."

Scott left him, probably to go talk to Allison or Lydia about Jackson. Stiles drained the rest of his punch and started to follow after him when he paused, hearing his dad's familiar voice.

"Why am I wearing black? What are you, an idiot?" Stiles whipped around to see his dad yelling at one of his classmates, dressed in a suit and holding a bottle of whiskey in his hands. "I just came from a funeral. You know, people wear black at funerals."

Stiles' eyes widened in shock as Noah took a long pull of the whiskey. Why was his dad even here? What funeral was he talking about?

"Dude, chill," the teenager held his hands up. "I was just—"

Noah roughly shoved him away. "Get out of my face."

He took another drink from the bottle and turned to Stiles, glaring at him with hateful eyes. "It's you. It's all you," he held the whiskey bottle up like he was making a toast. "You know, every day I saw her lying in that hospital slowly dying…"

This is about Mom, Stiles realized, his eyes stinging.

"I thought, how the hell am I supposed to raise this stupid kid on my own? This hyperactive little bastard who keeps running my life?" Noah pointed at his son, disgusted. "It's all you. It's you, Stiles. You killed your mother, you hear me? You killed her and now you're killing me!"

Stiles didn't say anything, he didn't move. How was he supposed to react when his dad was saying everything that he blamed himself for? His mom had died and he just stood and watched. He didn't do anything as the life left her eyes.

He flinched away as Noah threw the half-empty bottle at him, the glass crashing against the column he had been standing by. When he looked back at the area his dad had been standing, he was gone.

And then he was submerged in cold water.

Stiles inhaled deeply as he was lifted out of the pool, icy water dripping from his short hair down the back of his neck. He blinked rapidly and coughed, his eyes darting from Scott, who was in front of him, to one of their classmates. It was Danielle, who was known to be quite the character.

"What the fuck?" he spluttered.

"How do you feel?" Danielle asked simply.

"Like I might have to revisit my policy on hitting a girl," he glared at her.

Danielle sniffed, looking at Scott. "He's sober."

"Yeah, thanks, Danielle," Stiles rolled his eyes and got to his feet.

All around him, people were going crazy. There was some girl making out with a plant, two dudes were fighting over the last pig-in-a-blanket, and he had obviously had a hallucination about his dad because why the hell else would Noah even be at Lydia's party?

He turned to Scott. "What the hell is going on?"

When Scott had informed him that Lydia was no longer at the party, they both split up to look for her. While Scott took the inside of the house, where more people were freaking out, Stiles looked outside. There was no sign of Lydia, but there was wolfsbane in the punch bowl.

He hurriedly met up with Scott, who hadn't seen Lydia, either.

"Lydia put wolfsbane in the punch," Stiles informed Scott, trying not to think about how weird the situation was. "Anyone who drank it is freaking out."

Emphasizing Stiles' statement, people started pushing unsuspecting guests into the pool. Some of them enjoyed the little swim they would be privy to. But not Matt Daehler. He didn't know how to swim.

Realization hit Stiles and Scott at the same time. Matt had been in the library when Jackson turned into the kanima, he was the one who owned the camera that had footage of Jackson as a kanima on it. He had been at the rave when Kara was killed. The kanima's master wasn't able to swim and neither could Matt.

And the icing on top of the cake; Jackson—asshole extraordinaire—was the one who helped Matt out of the pool. Their suspicions were confirmed when the police showed up at the party and they tried to confront Matt. He was outside waiting for them, the kanima wrapped protectively around his legs.

Stiles immediately called Olivia, who picked up on the first ring. "Hello? Stiles?"

He could the stress in her voice and fighting in the background. "Matt Daehler's the one controlling Jackson," he told her. "Can you come?"

There was a second where she didn't answer and then, "I'm on my way."
