"Mommy," Lucius whispers. "Hold on, my love." Willow tells him looking back at the teens. "I just ended up here." Lydia admits. "Call dad." Willow tells her brother. "I already called 911." Lydia tells the two. 
"You called the police before you called me?" Stiles asks her. Lydia looks between the two Stilinski's confused, "I'm supposed to call you first when I find a dead body?" Lydia asks. "Yes!" Stiles yells. "Okay, let's dial this down." Willow tells the two teens. 
"Mommy." Lucius whispers, his eyes shining black. "Okay, I need to get him away from here and you need to call whoever you need to call. Then you and I will meet at the hospital and I wanna see this body up close." Willow says quickly. 
"Willow," Stiles calls out, "Do you know who did this?" Stiles asks. "No, but we should be scared."

"Should you really be bringing Luke with you? Dad would watch him." Stiles tells his sister pulling up at the hospital. "I don't want to leave him alone, not with him, not yet." Willow tells her brother softly. 
Stiles nods in understanding as he watches his sister hold her son close. He leads the two of them into the hospital, spotting Melissa. "Hey." Stiles greets her. "Hey - Willow Mae?" Melissa asks, surprised. 
"And this must be Lucius." Melissa says with a smile. "Melissa did my ultrasound. Helped me figure out I was pregnant." Willow tells her brother. "I'm just here for Stiles. I promise." She told the woman. 
"Over here. And if you tell anyone I showed you this, I swear to god, I will kill you painfully and slowly." She tells them. Stiles nods "Yep got it." He mumbles. "Why do you want to show us a body we've already seen?" Stiles asks. "Because you haven't seen everything." She whispers.
Lucius jumps out of his mom's arms as he stands on his tip toes to see the body. "He's gone." Lucius whispered sadly. "See this around his neck? That's a ligature mark. That means he was strangled with something like, cord, rope." Melissa says as she lifts the sheet off the body.
"Ah, okay, wait a second. What kind of werewolf strangles someone? You know, that's not very werewolfy." Stiles points out. "My thoughts exactly. And then there's this." Melissa turns the head to the side to see it smashed in.
"God, man, what is that?" Stiles turns around, "Is that brain matter? Yeah, it's brain matter, of course." 
"Here, take him." Willow says handing over her son. "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." Willow says with Melissa nodding. 
"All right, so this couldn't have been Boyd or Cora, you know? They wouldn't have done all that. So maybe this is just one murder. I mean, maybe it's just a random coincidence." Stiles tells Melissa and Willow. "I don't think it was just one." Melissa says. "How come?" Stiles asks slowly.
"Because that girl, over there, she's got the exact same injuries. 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 - Stiles?" Melissa and Willow both turn around to see the boy with tears in his eyes.
"Oh Mischief." Willow whispers as she turns back to the body of the girl. "Oh, my god, did you know her? I'm so sorry. I didn't even think." Melissa covers her body back up.
"I was- I was at her party. It was her birthday. Her name is Heather." Stiles says before whipping his eyes.
Willow looks between her son and the body remembering the picture he drew of the blond girl. "This wasn't us." Willow whispers. "This wasn't us." She says once more grabbing her son and holding him close for comfort. 
"Okay, we need to call your father, cause you're a witness." Melissa says to him. "Stiles?" Willow asks as her brother remains quiet. 
"Has anyone else been through here tonight? Any- any other bodies, or even anybody missing?" Stiles asks Melissa.
"Uh, no, no bodies, but um-" Melissa stutters out. "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?" Willow asks. "I don't know." Melissa tells her.
"Okay, first one." Stiles says. "Caitlin." "Is she here? Is she here right now?" Stiles asks."I think so." Melissa says to him. "Okay, where?" Stiles says as he tries to leave. "Okay, okay, wait." Melissa stops them, "Just wait a minute."
"I have to talk to her."
"Why?" Melissa asks, looking at Stiles. Stiles sighs as he and his sister share a look, "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 tells Stiles, Willow, Lucius and Melissa. "Right, but why tonight?" Stiles asks her. "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?" Willow asks her softly, "Three months."
"And you wanted to make it romantic." Willow says. "Yeah, you know because-"
"Because it was her first time." Stiles finishes for her, "They're gonna find her, right? Aren't they?" Caitlin asks looking up at them. 
"I have to go." Willow mutters to her brother as she storms out of Caitlin's room. "You can't just leave, Willow." Stiles yells at her, "We have to figure this out. You have to help me with this. You're my big sister." 
"Stiles -" 
"Why are you working for the bad guys?"  
"This isn't a game, Stiles." Willow tells him, "You are my brother, my family but the only family that Luke knows are here to get Derek. What this is, this is - this is dangerous. I'll help you but when we get what we want, we are leaving." 
Willow kisses the top of her brother's head before turning around and walking out. 
🌕
"Human sacrifices." 
"What?" 
Willow takes a seat next to Deucalion after putting Luke to bed. "It's human sacrifices. Someone is committing them here in Beacon Hills, Deucalion." Deucalion hums as he sits in silence for a moment. 
"Is this the time where you tell me that you are taking my grandson away from me to protect him? Or that you are switching sides and joining your brother and his friends?" Deucalion asks her. 
"I - I-" 
Deucalion stands up putting a hand on the girls' shoulder, "Go to bed. You need your rest." Deucalion says before leaving. Willow wipes away tears that fell on her face as she stands up and walks in her room. 
She picks up a picture frame of her and Charlie as teenagers and covers her mouth. "I need you Charlie."
