Brooke jumps out of the jeep just as Stiles stops, "Lydia?"

"Lydia?" He calls out as the two rush over to her, "Lydia, are you okay?"

"I'm okay." She says before pointing over to the lifeguard chair, "That, over there... Not okay."

The two look up and Brooke immediately turns away, "Oh my god."

"Yeah, all right. I'm gonna call my dad."

"I already called 911." Lydia says

"You called the police before you called us?"

"I'm supposed to call you first when I find a dead body?"

"Yes!" The twins exclaim

•••

"Are you sure?"

"Yep. Throat ripped out, blood everywhere. It's like the frickin' shining over here." Stiles says, "Two little twin girls come out of the woods, start asking me to play with them forever and ever, I'm not gonna be surprised."

"Can you get a little closer to make sure it was them?"

"Make sure it was them? Scott, who else is going around ripping throats out?" Brooke asks incredulously

"Please just do it." He sighs

Stiles looks over at Brooke and she immediately shakes her head, "Absolutely not. You're doing it."

He groans before ultimately turning back toward the body. He slowly steps closer to examine it. He glances over at Brooke before turning back, "Brooke, come here."

"What? No." She frowns

"Just- come here." He says

She sighs heavily before walking over. Making sure to stay behind Stiles, "What?"

"You see that?" He says pointing to the hand

"It's a purity ring." Brooke shrugs as she looks over at him, "What?"

"Okay, we have the animal attacks, right? Animals acting irrationally. Now we have someone dead."

"Which could've been Boyd and the girl." Brooke says. Stiles sighs, "Stiles, you were just on the phone arguing back with Scott because he didn't believe it was them."

"I know. I know." He says, "Just seems like there's more."

"Well, until we figure that out, I'm leaving. I can't stand to look at this anymore." Lydia says

"I can't keep looking at it either." Brooke says. She glances over again and grimaces, "Ugh, I'm gonna throw up."

______________________________________

"You didn't have to follow me home." Lydia says entering her room. Stiles stops near the doorway and Brooke leans on the doorway itself.

"I just wanted to make sure you got in okay." Stiles says

Lydia plops down on her bed, "I had a police escort."

"I know the inner workings of that force, all right? They're not nearly as reliable as people think."

"Well, you also didn't have to follow me into my room."

"Well, I... uh," He stammers turning to Brooke who raises her brows in agreement, "yeah, I don't have an answer for that. We can leave."

"Are you really gonna go without asking me the question that you've been dying to ask me?" Lydia scoffs

"Well, I'm not... I haven't been dying to ask anything. I... no questions here for Stiles. Nothing."

"I can see it on your face."

"Maybe my face just has, like, a naturally interrogatory exp... expression."

"Well, your interrogatory expression is getting on my nerves." She says making Brooke giggle, "The answer is, I have no clue how I ended up finding that body. I didn't even know where I was until I got out of the car."

"Yeah, but the last time something like this happened-" Brooke starts

"I know. Derek's Uncle."

"Peter."

Brooke and Stiles rushed into the hospital. Melissa turns to them, "Hey."

"Hey." Brooke says

"Over here." She says leading them down the hall, "And if you two tell anyone that I showed you this, I swear to God, I will kill you painfully and slowly."

"Why do you want to show us a body we've already seen?" Stiles asks

"Because you haven't seen everything." She says

•••

Melissa pulls back the covering and points, "See this around his neck? That's a ligature mark. That means that he was strangled with something, like cord, rope..."

"Ah, okay, wait a second. What kind of werewolf strangles someone?" Stiles asks, "You know, that's not very werewolf-y."

"My thoughts exactly. And then there's this." Melissa says before stepping over and turning his head

Brooke cringes and turns away, "Oh my God, what is that?"

"Is that brain matter? Yeah, it's brain matter, of course." Stiles grimaces

"See the indentation? He was hit in the back of the head, hard enough to kill him. In fact, any one of these things could have killed him. I mean, someone seriously wanted this poor kid dead." Melissa says

"All right, so then this couldn't have been Boyd or Cora, you know?" Stiles says looking to Brooke, "They wouldn't have done all that. So maybe this is just one murder. I mean, maybe it's just a random coincidence."

"I don't think it was just one."

"How come?"

"Because that girl over there, she's got the exact same injuries." Melissa says. She walks over to the other table with the two following her. As she lifts the covering, Brooke's heart drops, "The M.E. said this one wasn't just strangled. Whoever did it used a garrote, which is a stick that you put through the rope, and you just kind of keep twisting, and-" She pauses as she turns to them. Her face drops once she takes in their expressions, "Oh, my God, did you know her? I'm so sorry. I didn't even think."

She quickly covers them while Stiles wipes his eyes, "I was... I was at her party. It was her birthday. Her name is Heather."

"Okay, we need to call your father, 'cause you're a witness." She explains

Stiles stays quiet which grabs Brooke's attention, "Stiles?"

"Has anyone else been through here tonight? Any- any other bodies, or even anybody missing?" Stiles asks

"Uh, no, no bodies, but, um..." She trails off

"What?" Brooke asks

"Two girls. They brought the first one in, Caitlin, for a tox screen, and then I overheard that her girlfriend, Emily, just disappeared. I mean, they were out in the woods and-"

"Nobody's found her yet?"

"I don't know."

"Okay, first one." Stiles says

"Caitlin."

"Okay. Is she here? Is she here right now?"

"I think so."

"Okay, where?" Brooke asks, "Where is she?"

"Okay, okay, wait. Just wait a minute." Melissa says

"We have to talk to her." Stiles says

"Why?"

"Because I think I know what's happening."

______________________________________

"We weren't doing anything that bad. I mean, I've camped out there plenty of times." Caitlin explains

"Right, but why tonight?" Stiles asks

"We wanted to be alone for one night. Emily lives with her mom, and I have three roommates. Not exactly romantic settings, you know?"

"How long have you two been together?" Brooke asks

"Three months."

"And you wanted to make it romantic."

"Yeah, you know, because..." Caitlin says sheepishly

Stiles nods, "Because it was her first time."

Caitlin looks between the two of them, "They're gonna find her, right? Aren't they?"

Brooke and Stiles turn to each other with a knowing look.

______________________________________

Later that night, Brooke and Stiles stood with Scott as they showed him the lacerations to Heather's and the other victim's neck. Stiles then pulls the covering back over Heather's body.

"So Boyd and Cora might not have killed anyone?" Scott asks

"You're gonna wish they did." Stiles sighs

Scott furrows his brows, "Why?"

"We're not exactly sure yet. The other girl who was out in the woods, Emily?" Brooke says and he nods, "Eventually they're gonna find her. She's one of them. Emily, Heather... That guy Lydia found at the pool. All three were virgins and they're all gonna have the same three injuries. Strangled, throat slashed, head bashed in. It's called the threefold death."

"So if these aren't random killings, then what are they?"

"Sacrifices. Human sacrifices."
