Lydia sent Molly a text to meet her at the school swimming pool.

Molly ran to the school and made her way to the pool.

When she got there, Lydia was hovering over a dummy. Molly looked around, then up at the chair just as Lydia screamed.

"Lydia!" Molly called, catching her attention. "Why are you here?"

She shrugged. "I don't know. I was on my way to the store to get ibuprofen for a headache and I ended up here. There's a dead body, Molly."

"It's all right. Call the sheriff's station while I call Stiles. He can help."

She nodded and called the station. As soon as Stiles arrived, he asked, "Lydia? Molly? Are you okay?"

Lydia glanced to Molly. "I'm okay. Molly's okay. That, over there..." she pointed to a lifeless boy in the lifeguard chair, "Not okay."

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

"I already called 911," Lydia replied.

Stiles frowned. "You called the police before you called me?"

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

"Yes!"

Molly glanced Stiles. "I called you while she called 911."

Stiles called Scott and relayed the information. He said after a moment, "Yep. Throat ripped out, blood everywhere. It's like the frickin' Shining over here. Two little twin girls come out of the woods, start askin' me to play with them forever and ever, I'm not gonna be surprised."

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

Stiles hung up and Molly asked, "The werewolves?"

He nodded. "Boyd and Cora. That's what Scott is thinking."

Molly turned to Lydia. "You want some company?"

Lydia nodded. "That'd be great."

The police arrived and escorted Lydia home. Stiles insisted on following them. When they got inside, Lydia said, "I had a police escort, and I've got Molly with me."

Stiles shot her an innocent look. "I know the inner workings of that force, all right? They're not as reliable as people think."

Molly crossed her arms. "But you didn't have to follow me and Lydia into her house."

Lydia frowned. "Well, you also didn't have to follow us into my room."

Stiles glanced around the room. "Well, I... uh, yeah, I don't have an answer for that. I can leave."

Molly looked at him suspiciously. "What, Stiles? You look like you're dying to ask something."

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

Lydia narrowed her eyes. "Tabitha and I can see it on your face."

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

Molly shook her head and deadpanned, "No. It doesn't."

Lydia nodded. "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."

Stiles frowned. "Yeah, but the last time something like this happened..."

Lydia let out a sigh. "I know. Derek's uncle."

"Peter," Molly realized. "That was you?"

She shrugged. "I didn't know I was doing so."

Stiles turned to Molly and said, "Melissa needs me at the hospital. Says she has to show me something. I'll call you. Or text you. Or both."

Molly nodded and Stiles waved goodbye.

When he left, Lydia turned to Molly. "Did you see how he was looking at you?"

Molly frowned. "No, what way?"

"Molly, you are so oblivious. He likes you."

"What? No. He likes you."

"Trust me, Molly. It's you he likes."

"I don't want to talk about this anymore. Did you take ibuprofen?"

She nodded. "Yeah. My headache is subsiding. Thanks for coming."

"Yeah."

Lydia and Molly sat in a comfortable silence and Molly got a text from Stiles. Molly let out a sigh. "Heather, Stiles' friend, is dead."

"I'm sorry, Molly."

"No, it's fine. I just... I-I feel bad for Stiles."

"How are you, Molly? Honestly."

Molly shrugged. "I'm fine."

"Are you?"

"Yes. I'm fine."

"Molly-"

"Lydia, no offense, but I'm not in a chatty mood. We have school tomorrow. Goodnight."

A honk outside sounded and Molly looked out Lydia's window to see Stiles motioning for her to come down. Moments later, her phone buzzed. 'Molly, I need to show you something'.

Molly sighed and glanced at her friend. "I'm being called. You gonna be all right here?l

Lydia nodded. "I'll be fine. Go on."

"I'm sorry for snapping at you."

"It's okay."

Molly made her way outside and followed Stiles to his Jeep. She climbed into the back since the passenger's seat was taken by her other friend.

"You all right, Stiles?" she asked.

He nodded. "Yeah, I'm good. Sorry to take you from Lydia."

"It was a relief."

"Why, did something happen?"

"Some things were said."

"Are you okay?"

"Let me get back to you on that."

They arrived and Stiles took his friends to the morgue and showed them Heather's body. Molly noticed a dark line around her throat. Scott glanced up at his friend. "So Boyd and Cora might not have killed anyone?"

Stiles gave him a grim look. "You're gonna wish they did."

Molly stared at Heather as she asked, "Why?"

Stiles let out a sigh. "I'm not exactly sure yet. The other girl who was out in the woods. Emily? 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."

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

"Sacrifices. Human sacrifices."

"Oh, my god," Molly mumbled. "I better let Sam and Dean know."
