Selene POV: Stiles' dad was just taken by the Darach who turned out to be their English teacher Ms. Blake. Scott, Stiles, and Selene raced over to Derek's to tell him what they knew.

"Derek trust me Jennifer is the Darach I saw it with my own eyes. She tried to kill Lydia then took Stiles' dad" Selene explained knowing Derek would listen to her.

Selene kept a tight grip on Stiles' hand he was so close to losing it. The three of them hid when they heard Jennifer show up to see how she would play it.

"Derek? Derek where are you?" Jennifer yelled running into his loft.

"Right here" Derek said stepping out of the shadows.

"Thank god. Something happened at the recital. At the school. Okay I need to tell you before you hear it… before you hear any of it from them" Jennifer said as she ran to Derek and hugged him.

From their hiding place Selene put her body between Jennifer and Stiles who was shaking with rage and pain.

"From who?" Derek asked playing dumb.

"Scott, Stiles, and that girl Selene. They're gonna tell you things. Things you can't believe. You have to trust me okay? You trust me."

"What is it?" Derek asked.

"Promise you'll listen to me."

"I promise."

Then she kissed Derek only to pull back.

"They're already here aren't they?" She asked and Derek looked behind her as Stiles, Selene, and Scott walked out.

"So they told you it was me? That I'm the one taking people?" Jennifer asked pissed off.

"We told him you're the one killing people" Scott said.

"Oh that's right. Committing human sacrifices? What cutting their throats? Yeah I probably do it on my lunch hour. That way I can get back to teaching high school English the rest of the day. That makes perfect sense" Jennifer said.

"Where's my dad?" Stiles asked crying slightly.

His pain caused Selene's eyes to turn red and her claws come out.

"How should I know? Derek tell me you don't believe this" Jennifer begged.

Derek looked back at Scott then Stiles as more tears ran down his cheeks to Selene who was ready to kill for her mate.

"Do you know what happened to Stiles' father?" Derek asked.

"No."

Selene heard her heart beat increase to tell she was lying only Stiles' death grip on her hand kept her from tearing Jennifer apart.

"Lie" Selene snarled.

"Ask her why she almost killed Lydia" Scott said.

"Lydia Martin? I don't know anything about that."

Again Selene snarled "Lie."

"What do you know?" Derek asked getting mad.

"I know that they for whatever misguided reason are filling your head with an absurd story. And one they can't prove by the way" Jennifer said looking back at them with a sneer.

"What if we can?" Scott said holding up a glass jar with powder in it.

"What is it?" Jennifer asked.

"My boss told me it's a poison and a cure. Which means you can use it…and it can be used against you" Scott said stepping forward.

"Mistletoe?" Jennifer said.

Then Scott tossed the dust on her. As it formed a cloud around her her true self was revealed she was the Darach. When the dust settled she tried to run but Derek grabbed her by the throat.

"Derek wait wait you need me" she gasped.

"What are you?" Derek asked as he flicked his claws out.

"The only person who can save your sister. Call Peter. Call him!" Derek called Peter while holding Jennifer by her throat.

"It's not good. She's in and out of consciousness. She's vomiting up black blood along with one other alarming substance"

Selene heard Peter say through the phone.

"Mistletoe" Derek said.

"How did you know that?" Peter asked.

Derek closed his phone and started to squeeze Jennifer's throat.

"Derek. Derek what are you doing?" Scott asked worried.

"Her life… it's in my hands!"

Then Derek lifted her off her feet by her throat.

"Stop. Derek stop!" Stiles yelled stepping closer.

"Stilinski you'll never find him" Jennifer said to Stiles.

"Derek. Derek!" Scott yelled when he only squeezed harder.

Finally Derek let go and Jennifer fell to the ground.

"That's right. You need me. All of you" she said.

Selene let go of Stiles' hand and slowly went to crouch in front of Jennifer. She didn't speak just flicked her claws out and cut Jennifer on her arm and licked the blood off.

"What is she doing?" Scott asked.

"Sh it's a type of magic I've only seen her do" Derek said softly.

Next Selene shifted into the big white wolf letting her senses take in everything. Derek stepped away then only to come back with a blanket. When Selene shifted back naked Derek put the blanket around her.

"I have your blood and your scent now. I can find you anywhere. You know who I am. If you betray us know this…" Selene let her eyes go red again. "You won't last long."

They could all tell Jennifer was scared but she hid it well. Selene walked back over to Stiles and took his hand again and looked at Derek after seeing tears still in Stiles' eyes for his dad.

"If it comes times to kill her… she's mine."

Derek just nodded.

Stiles POV: Derek and Jennifer got into Derek's vehicle and Selene, Scott, and Stiles got in Stiles' Jeep and followed Derek. Selene got dressed in the back of Stiles' Jeep.

"I don't know something feels wrong about this. You know we proved it to Derek but she still had this look like it didn't matter. You know like it was all still going according to plan. You saw it didn't you?" Stiles asked.

Selene nodded Scott said nothing. They stopped in front of the hospital. Stiles grabbed a bat out of the back of his Jeep. The rain had them soaked in seconds.

"What's that?" Scott asked.

"Well you two got claws. I got a bat" Stiles responded.

"Scott! Scott! What are you doing here? The hospital's evacuating" Scott's mom said once they were inside.

"We're here for Cora" Scott told her.

"What all of you? Why does Stiles have my bat?"

"Mom just trust me on this. You need to get out of here. Right now."

"The building is supposed to be clear in 30 minutes. We've got two ambulances that are coming back. One's 10 minutes out the other's 20. Cora needs to be on one of those. They'll be picking up in the basement garage."

"Got it okay."

Then they headed for Cora's room and piled in the elevator.

"You don't have to keep me on a leash Derek. I'm going to help" Jennifer said.

Derek didn't release his grip. Jennifer turned and saw Scott glaring at her and on the other side Selene was watching her while Stiles tightened his grip on the bat. When they got off the elevator the lights started to flicker from the storm.

They got to Cora's room only to see her and Peter were gone. There was a black blood trail leading through another door.

"Derek" Scott said looking at the blood then the door.

Roars and growls came from behind the door just before someone came crashing out to land at Derek's feet.

"We got a problem. Big problem" Peter said as he sat up.

There at the end of the hall was the combined form of the Alpha twins. Derek went wolf and attacked but the mega Alpha the twins quickly knocked him down. Scott also wolfed out ran at them jumped off the wall to punch their face.

Behind the fighting Stiles saw a passed out Cora. He grabbed Selene's hand and knelt next to Peter.

"Help me" he said as he started forward slowly.

Scott fought hard but the twins pinned him to the wall allowing Stiles, Selene, and Peter to get to Cora.

"Ethan Aiden stop! You don't know what you're doing!" Scott yelled.

"All we want is her" they replied.

But when they all looked Jennifer was in a closing elevator leaving.
