Blair stood in front of Scott as he wrapped his arms around her chest as he knew Blair would try and escape to attack Jennifer Blake the moment she entered the Hale's loft. Blair leaned against Scott as she tried to breathe slowly in and out to calm herself down before the desire to seek revenge against Jennifer overcame her instincts and she jumped on her before it was time.

"Derek, where are you?" Blair gritted her teeth in anger at Ms. Blake's voice, the three had already told Derek about what had happened and she knew without a doubt that Derek would believe them over Jennifer, but the sole fact that Jennifer came here to try and turn Derek against them in the first place infuriated her beyond belief.

"Right here," Derek called out, Blair breathing out heavy as she watched Jennifer run into Derek's arms and began embracing him. The sight of the couple together, making Blair want to throw up especially since she knew Jennifer was the one committing all sacrifices now.

"Something happened at the recital. At school. Okay, I need to tell you before you hear it before you hear any of it from them." Scott slowly releasing his arms from Blair as he held her hand instead. The three nodding to each other as they decided it was time to move soon, and confront Jennifer before she started to twist their story.

"From who?" Derek asked, feigning clueless as if Scott, Stiles, and Blair hadn't already explained the entire situation to him before Jennifer had even entered his loft.

"Scott, Stiles, Blair. They're gonna tell you things. Things you can't believe. You have to trust me, okay? You trust me." Blair grabbed Stiles's hand on her other side, the three all trying to contain the anger at their English teacher - mostly Stiles and Blair who seemed to be seething in anger at the moment. Even though Jennifer hadn't hurt anyone close to Blair, she was bitter at the fact that she had come even close to killing Blair and Lydia in the first place.

"What is it?" Derek asked, pretending he would possibly take Jennifer's side over the three or even remotely hear her side of the story.

"Promise you'll listen to me," Jennifer begged Derek as Blair silently gagged in disgust at Jennifer's desperateness for Derek to remain loyal to her instead of his pack.

"I promise." The trio began moving out of their hiding spot, dropping their intertwined hands as they walked out to face the woman who had caused them so much pain tonight.

"They're already here, aren't they?" Ms. Blake turned to see Scott, Stiles, and Blair walking up to the pair while glaring at her, Scott holding a jar of mountain ash in his hand that Jennifer still hadn't noticed yet. Scott intending on using it to reveal Jennifer's true nature to Derek.

"So, they told you it was me? That I'm the one taking people?" Jennifer asked Derek as if the possibility of her even being the Darach was completely preposterous. Jennifer still trying to play the innocent school teacher act against Derek whereas the group already knew she was lying to all of them.

"We told him you're the one killing people." Scott corrected. Blair had blood covering her entire right leg where the woman had stabbed her and bullet wounds cover her shirt and her throat still had blood covering it.

And that was most of the evidence the three needed to convince Derek to believe them, anyone who hurt Blair was immediately the enemy to Derek. But Blair knew that Derek did genuinely like Jennifer, and the news of her being the Darach was going to be hard for him.

"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 for the rest of the day. That makes perfect sense." Jennifer continued sarcastically, trying to persuade Derek that everything the teenagers were saying was preposterous. Blair crossing her arms against her chest as she listened to Jennifer continuing to tell her blatant lies.

"Made sense when you tried to slice my throat an hour ago, bitch." Blair spat out still angry that the woman had nearly killed her less than an hour ago. Her anger fuelling her rather than having the patience to wait for this conversation to end.

"Where's my dad?" Stiles asked, Blair's face softening once she saw the tears running down Stiles's face. Blair's guilt coming back that she wasn't able to do anything for his Her hand reaching across to grab Stiles's as she squeezed it in comfort, knowing he needed the reassurance right now.

"How should I know? Derek, tell me you don't believe this." Blair could see that there was some conflict in Derek's eyes even if he had a complete poker face currently, Blair knew all of Derek's tells by the back of her hand and the fact that Derek's love for Jennifer might actually sway his decision turned Blair's stomach into knots.

"Do you know what happened to Stiles's father?" Derek asked coldly as Jennifer let out a quiet no, almost whimpering at Derek's accusations towards her even if they were completely true.

"Ask her why she almost killed Lydia. Why she almost killed Blair." Scott spat out in disgust, reminding Derek that Jennifer had tried to hurt the girl who was practically an extension of his family as well as Lydia, who was completely innocent in all of the fights with the Alphas. Neither of the two having done anything to warrant Jennifer trying to kill them.

"Lydia Martin? I don't know anything about that. And I would never hurt Blair, I know how much she means to you, Derek." Blair let out a quiet bitch under her breath when she heard the lies Jennifer was trying to feed Derek. Everyone in the room knew Derek and Blair were family and Stiles was hoping that would be enough to convince Derek to help him save his dad and to trust that they were telling the truth.

"What do you know?" Derek asked, snapping Jennifer out of the beginning of another possible rant to try and plea her innocence to Derek.

"I know that these boys and Blair, for whatever misguided reason, are filling your head with an absurd story. And one they can't prove, by the way." Jennifer turned to three as Scott held his jar up filled with mountain ash as he was about to prove Jennifer wrong.

"What if we can?" Scott asked, actually breaking Jennifer's confident facade at being able to manipulate Derek into her way of thinking. Jennifer had strongly believed that her past relationship with Derek would be a weakness for him but the three of them had thought of everything to make sure she couldn't break Derek.

"What is that?" Scott stepped forward to Jennifer as he slowly began to unscrew the top of the jar, getting closer to Jennifer as he did so. Blair and Stiles staring at her coldly as they waited for the next step of the plan.

"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 informed as Derek began to step away from Jennifer - letting Scott finish the last step of his plan without getting himself caught in it.

"Mistletoe?" Scott finally threw the powder at Jennifer as she threw her hands up, her face contorting into the Darach. Jennifer tried to run out of the loft once she realized Derek finally had concrete evidence that the three were telling the truth. Unfortunately for Jennifer, Derek grabbed her by the throat and forced her back before she could even try and escape.

"Derek, wait, wait! You need me." Derek flicked his claws out as his grip on Jennifer became tighter as she began to struggle for air.

"What are you?" Derek asked, staring in anger at his now ex-girlfriend. His anger radiating throughout the entire room, all of them knowing how pissed Derek was at Jennifer for betraying him.

"The only person who can save your sister. Call Peter. Call him!" Derek turned to Blair who was already scrambling to take her phone out as she dialed Peter's number, walking over to Derek as Peter finally picked up the call.

"Peter, how's Cora?" Blair asked for her and Derek, the two awaiting the answer as they tried to decide what they would do with Jennifer now that Cora's life was possibly at stake as well.

"It's not good. She's in and out of consciousness. She's vomiting up black blood along with one other alarming substance." Blair held the phone out on loudspeaker as both she and Derek listened to the news from Peter on Cora's condition as he confirmed Jennifer's words that Cora was in trouble.

"Mistletoe." Derek breathed out as he still had his grip tight on Jennifer's neck who was glaring at both Derek and Blair in front of her.

Blair hung up the phone on Peter as she forced Derek to drop his grip on Jennifer. Blair holding Jennifer up by the neck as her veins turned black, slowly taking the life out of her. Blair being more successful than Derek when it came to threatening Jennifer since everyone knew Derek would actually hold more restraint than Blair would.

"I'm going to kill you. No one hurts my family." Blair whispered in her ear as Jennifer began gasping for air. Blair drowning out Scott's calls behind her as she refused to let go. Scott calling to Derek to try and snap Blair out of it before she killed Jennifer as Derek also decided to ignore Scott's words as him and Blair kept their concentration on Jennifer in front of them.

"Her life, it's in my hands!" Jennifer called out, reminding her that whether Cora lived or die was up to her. She had control over at least one person that everyone in the room cared about, having multiple lives in her hands.

"Stop. Blair. Stop!" Stiles called out as Blair's eyes turned black as Derek did nothing to stop Blair besides crossing his arms against his chest - remaining completely stoic as he watched his little sister drain the life out of his ex-girlfriend.

"Stilinski, you'll never find him." Blair dropped Jennifer once she told her that and threw her on the floor knowing she couldn't just let Stiles's dad die.

"That's right. You need me. All of you." Jennifer taunted as Blair bent down on her knees and grabbed Jennifer by her chin as she realised Jennifer was getting too cocky for her taste.

"As soon as we find no use of you anymore, I'm going to kill you. Understood?" Blair waited until Jennifer nodded her head before she let go and walked over to Stiles and Scott.

"Thanks for not killing her." Stiles thanked Blair who knew that the anger she held towards the woman was nearly as great as his. Stiles settled his hand on her shoulder before the group began to leave the apartment to go save Cora Hale.

—•—

"You should know I'm not doing this because I have to. I want to. I could still run, and you wouldn't have an easy time stopping me. But I don't want your sister to die. I'm only doing what I had to do." Jennifer explained to Derek in the car, while Derek kept his eyes trained on the road ahead of them. Jennifer seeming to forget about the third person in the car who was listening into her conversation.

Blair leaned forward from the middle-seat, the only reason for her being in this car instead of Stiles's jeep was so that Jennifer couldn't even try to sway Derek at all. Blair being the buffer to remind Derek of the side he should be on as she was a physical reminder of what Jennifer had done tonight to his family.

"You literally tried to kill a part of his family literally less than an hour ago. And you put Cora in the hospital. All you." Blair pointed out as Jennifer continued to talk to Derek regardless of Blair's words.

"You need to hear the whole story, Derek. You need to know just how connected we really are. Even Blair." Blair sat back in her seat as she glared at Jennifer from the back seat, wishing she could just kill the woman rather than listening to her pointless rants.

"Funny, because anytime I hear something come from your mouth I get the sudden urge to commit homicide," Blair confessed, her eyebrows scrunching in fake confusion as she stared Jennifer who was glaring disgustedly back at the teenage girl behind her. Derek rolling his eyes at Blair's threats to Jennifer even if he was currently thinking the same exact thing.

"Stop talking," Derek ordered Jennifer as he pulled up to the hospital, running to the passenger seat to grab Jennifer as Blair grabbed her pole-arm as she ran out into the rain following behind Derek and Jennifer. Stiles turned to Blair when he saw her weapon and the two nodded in appreciation at the other's weapon. Blair decided not to tell Stiles that a baseball bat made of wood was probably not going to do that much damage to anyone.

"Scott! Scott! What are you doing here? The hospital's evacuating." Melissa ran up behind the group as they turned around to check on Melissa. Scott stepping forward to explain to her what was happening since they were in a rush.

"We're here for Cora," Scott explained, knowing his mother had been taking care of Cora in the hospital.

"What, all of you? Why does Stiles have my bat?" Melissa asked as she stared at the stolen wooden bat that Stiles had managed to steal from her house without her knowing.

"Mom, just trust me on this. You need to get out of here. Right now." Scott tried to convince his mom to get out of the hospital, not wanting her to become another victim of the Darach who was standing behind him.

"The building is supposed to be clear in 30 minutes. We've got two ambulances that are coming back. One's ten minutes out, the other's twenty. Cora needs to be on one of those. They'll be picking up in the basement garage." Melissa explained to Scott who nodded before turning and following the group again. Scott reminding himself of the times as the rest of the group became alerted at the limited time frame they now had.

The five stepped into the elevator, Blair, Scott, and Stiles standing behind Jennifer as they glared at the back of her head while Derek kept a tight grip on her hand.

"You don't have to keep me on a leash, Derek. I'm going to help." Jennifer turned her head to see all three teenagers behind her staring daggers at her as both Blair and Stiles twisted their weapons in anger at her. Jennifer bringing her attention back to the front of the elevator as she realised her plan was going to be harder than she thought.

Blair followed Derek out of the elevator, the hallway completely silent as the lights flicked on and off around them. The group came to a stop at one of the hospital rooms as they spotted the vacant hospital bed along with a pool of black blood beside it. The room that Cora was supposed to be in.

"Derek," Scott called out, the group following his stare of the trail of black blood on the floor that came to a stop at the wooden doors standing in front of them. The group became quiet when they heard yelling and the wooden doors finally opened as Peter Hale was thrown out, sliding to a stop in front of them as he stared at the group standing above him. Blair's eyebrows furrowing in confusion as she stared at Peter on the ground as she wondered what mess the man had got himself into this time.

"We got a problem. Big problem." Peter told them, Blair pushing Stiles behind her once she spotted the Alpha twins at the end of the hallway - not wanting them to get their claws into Stiles since he was the only one that couldn't heal fast.

Derek was the first to wolf out and ran to attack twins who quickly threw him to the side after a couple of punches. Stiles grabbed Peter as the two-spotted Cora unconscious on the floor. Blair watched as Jennifer walked backward as she followed her - not giving her the chance to escape as she ran to stand in the elevator with her. The two girls standing at opposite sides as Blair glared heavily at her.

"The deal was that you help Cora. Where the hell do you think you're going?" Blair asked, swinging her pole-arm as she got closer to Jennifer. Jennifer trying not to back-up further when Blair approached her, not wanting to give Blair an excuse to attack her.

"If I stayed up there, the twins would have killed me, Blair. I'm not that stupid. You can bring me back up, once they're gone." Jennifer lied, knowing that if she told Blair that she indeed was attempting to escape that Blair wouldn't have hesitated to push her pole-arm through her chest without hesitating.

"Good, now let's go," Blair ordered Jennifer, the two girls stepping out of the elevator as Kali and Deucalion approached them in the hallway.

"Oh, you've got to be kidding me." Blair hissed under her breath as Deucalion took the cap of his cane before throwing it next to Jennifer's head. Blair grabbing the woman roughly and shoving her back in the elevator since both of them knew that they couldn't take on the two Alphas.

"Press the damm buttons, Jennifer," Blair yelled at her as Jennifer began moving to push the buttons as Blair stood at the entrance of the elevator watching as Kali ran towards them as the doors began to slide close. Kali tried to claw open the elevator doors as Blair stabbed her through the leg with her pole-arm, tossing her to the side before yanking it out of her chest as the doors finally closed behind her.

"You are so not worth this amount of trouble," Blair told Jennifer as the woman tried to get closer to Blair to talk to her - knowing that it would help to have Blair on her side to convince Derek to trust her. Jennifer not taking into account that Blair didn't want Jennifer anywhere in her vicinity without wanting to kill her.

"Back off!" Blair yelled at Jennifer when she tried to approach her, the elevator doors finally beginning to open.

"I just want to talk, Blair." Jennifer tried to convince Blair in order to get her to stop trying to kill her. Even if it was a total lost cause.

"And I just want you to shut up but we can't all get what we want, can we Jennifer?" Blair asked sarcastically, Jennifer finally shutting up since she knew she wasn't going to be able to get inside Blair's head currently.

Blair finally dragging Jennifer by the elbow as the two went to go find the boys that they had abandoned during the fight with the Alpha twins - well, that Jennifer had abandoned.

The two finally opening one of the doors once they heard the voices of Derek Hale and Scott McCall discussing their next plan - Jennifer interrupting their conversation to vouch for herself by stating that only she can save Cora.

"You can't. Only I can. I can save her and I can tell you where Sheriff Stilinski is. But there is a pack of Alphas in this hospital who want me dead and the Valkyrie standing behind me who keeps threatening me. So I'll help you, but only when I'm out of here and safe. Only then." Blair dropped her grip on Jennifer's elbow as Derek launched forward, Jennifer grabbing Blair and pulling the girl in front of her since she knew Derek wouldn't hurt Blair to get to her. Derek stopping in front of Blair who easily moved out of his way so that he could get a better shot at Jennifer.

"She was trying to get out," Derek yelled once Scott grabbed him by his shirt and held him back from attacking Jennifer since Scott knew that the group needed her - even if all of them wanted to have a go at Jennifer but unfortunately they needed her more than she needed them at the moment.

"I was trying to keep myself from getting killed. You can't blame me for that. Even ask Blair." Jennifer argued pointing to Blair who nodded her head despite the fact she wanted to rip Jennifer's head off her body for even talking as if the two were allies.

"If you want to show you're one of the good guys, then heal her." Stiles reminded Jennifer as he held his hand towards Cora's body, as Blair finally yanked Jennifer's grip off her arms, moving away from the woman's disgustedly.

"Not until I'm safe." Jennifer once again argued - not wanting the Alpha pack to get their hands on her while they were still in the hospital.

"I'd like to volunteer a different method of persuasion. Let's torture her." Peter suggested both Derek and Blair actually agreeing with Peter. Blair flipping her pole-arm around as she got ready to actually correspond with Peter's plan.

"Works for me." Both of them responded, Blair about to turn and stab Jennifer before the voice of Melissa McCall flowing through the speakers halted everyone in the room - each of them snapping their heads towards the speakers as they began to listen to what she had to said.

"Uhm, can I have your attention?" Mr. Deucalion... Excuse me, just Deucalion, requests you bring the woman calling herself Jennifer Blake to the E.R. reception. Do this, and everyone can leave. You have ten minutes." Blair stopped, moving away from Jennifer as she could tell how terrified Scott was of Deucalion having his mom.

"He's not gonna hurt her," Jennifer spoke up, both Blair and Derek telling her to shut up - tired of hearing her voice every five seconds whenever they tried to think.

"Jennifer, no one wants your input or cares. Stop talking." Blair put up her hands in frustration, not realizing she was throwing her pole-arm up as Peter ducked underneath it and grabbed it before she could slice his head off.

"He won't! Scott, you know why. Tell them it's true." Blair stopped once Jennifer spilled one of Scott's possible secrets, both Blair and Derek turning to Scott for an answer.

"What does she mean?" Derek asked, Scott still not answering as he avoided both his and Blair's stares. Derek wanting to know what was going on rather than his pack keeping secrets from him.

"Scott?" Blair asked waiting for Scott to fill them in on what Jennifer was trying to tell them since the woman constantly beat around the bush when it came to getting her point across.

"You're not the only one he wants in his pack. Deucalion wants all three of you in his pack." Jennifer revealed, looking towards Blair at the end as Peter shifted his shoulders.

"I'm beginning to feel left out," Peter added sarcastically as Derek glared at both Scott and Blair for neither of them telling him that Deucalion also wanted them especially Blair since he expected her to come to him when she was in danger. Derek still not realising that Blair was able to protect herself now and didn't need to depend on her older brother for help.

"It's because no one wants you in their pack Peter, literally no one. Not even the other evil werewolves want you." Blair replied, sighing when Peter tried to involve himself in the conversation when he wasn't needed or even wanted.

"We are having a conversation when this is over," Derek warned Blair, already knowing Scott would want to overly explain himself to Derek whereas Blair would actually try and get herself out of trying to talk to Derek about accidentally keeping something from him as important as Deucalion trying to recruit her into his pack.
