Chapter 05: I'm Not Killing My Brother

Emilia left her fathers office, and stopped to crouch down in front of Isaac. One of the officers moved to stop her but Noah shook his head. Emilia glanced up at her father and smiled at him silently thanking him for letting her talk to Isaac.

"Isaac," Emilia was quiet as she spoke looking back to Isaac and putting her hand on knee. "Look at me, we'll work it out. I promise," Isaac nodded almost numbly as he looked at Emilia.

"Em, go home," Noah said after a second of not hearing his daughter speaking.

"Dad, just look after him," Emilia said motioning to Isaac as she spoke. "He's a good kid,"

"I know," Noah nodded before ushering Emilia out of the station. "Go home Em, and thank you,"

"Bye pops," Emilia called before disappearing out of the station and across the road to where Derek was waiting for her hidden out of view.

Derek glanced up at Emilia as if to say what did you find out, before he actually spoke. "Why is he in there?" Derek questioned as they drove off and headed back towards Emilia's.

"They think he killed his old man," Emilia told him, that was what she had gathered from all the chatter while she was in her fathers office.

"He didn't we both know that," Derek said putting his hand on Emilia's as they stopped at traffic lights. "The full moon's tonight, he doesn't have enough control,"

"Show Scott what his old man was doing," Emilia took a deep breath, they were both certain that none of the teenagers knew what was going on in the Lahey home.

Derek nodded, he'd take Scott and show him what was going on in the basement of the Lahey's house. He wasn't entirely sure that Scott was ready to see what was going on, but was anyone really? Jackson Whittemore, another of the boys from the lacrosse team had on the other hand told the Sheriff about what he'd seen.

"Just promise me you won't get caught," Emilia said, they had to work out how to get Isaac out of the station for his first full moon. "Once you get him bring him to mine,"

"You sure your old man won't come here?" Derek questioned, Emilia nodded she'd told him that the only time he was to go to hers was if she asked him there.

"I'm sure, he knows that I don't want people at the moment...hell he thinks I'm tolerating you and you're my best-friend," Emilia answered, running leaning against the window of the Camaro as Derek drove.

A few hours later and Emilia was looking after Isaac, while Derek and Stiles tried to work out what to do. Derek wanted to lock him up but Emilia convinced him otherwise to let her deal with him. Derek and Stiles had broken him out while Scott and Allison went to Isaac's and used the freezer to contain Scott.

"Isaac, sweetheart I need to you to concentrate...I don't want to lock you up," Emilia spoke calmly to him, before she found herself needing to pull Isaac into her arms to get him sit still. "Isaac, listen to me," The two of them were in her bedroom while Derek and Stiles talked in the lounge.

"Uh uh," Isaac mumbled, Emilia sighed and held him tighter as his eyes flashed orange at her.

"Derek! A little help in here!" Emilia hissed, hoping that only Derek would enter the room and not her human little brother.

"What Em?" Derek questioned, as Stiles raced to the room and skidded to a halt when Isaac moved to lurch at him. "Stiles, stay back,"

"We're not locking him up but I do need your help," Emilia told him before motioning for Stiles to stay back with her head while still holding Isaac.

Derek growled causing Isaac to whimper and his eyes to retreat to their normal blue. Stiles still couldn't understand how the whole alpha-beta relationship worked. Emilia was slowly convincing Scott that Derek could help him. Isaac curled into himself and into Emilia as she kept her arms around him.

"I'm going to kill my brother and Scott," Emilia muttered under her breath as she looked around the room.

"Don't kill them," Derek muttered in response as he looked at Emilia and then at Isaac. "Let me,"

"Hey! I was joking. You on the other hand, I know you want to kill them. But please just don't I'll talk sense into them some how," Emilia said as she ran circles over Isaac's back and he started to slowly calm down more. "Isaac, sweetheart just listen to my voice you don't have to take in what's being said just listen to it," Isaac nodded into her shoulder and allowed himself to listen to her eventually falling asleep.

"Keep an eye on him, you may be the only thing that keeps him safe," Derek told her as he stepped back and leant against the door frame. Stiles didn't want to keep from his father that he knew where Isaac was but if he wanted his sister to stay he'd have to.

"As long as you don't kill my brother and Scott," Emilia spoke quietly as she kept Isaac close to her on her bed which was where they had ended up. "Try and sleep sweetheart,"

"You better know what you're doing Em," Derek said before going back out to Stiles in the living room.

"I do...I hope," Emilia muttered taking a deep breath as she closed her eyes and concentrated on Isaac's breathing. 'Whatever his dad did, did a number on him,' Emilia thought to herself as she lay Isaac down but didn't move from where she was.

A week later and Derek had also bitten two more teenagers, but only after giving them the choice with Emilia present. Scott and Stiles couldn't understand how Emilia was okay with what he was doing.

"And you're okay with Derek turning teenagers?" Scott exclaimed seemingly forgetting that Emilia had been turned when she was much younger than what they were.

"I was a kid. Younger than you, and yes Derek can be an asshole I know that," Emilia said watching as Scott took on Isaac and Erica. "Trust me, I know what he's doing,"

"Are you sure?" Scott growled watching as Emilia turned wolf in front of them.

"Always, so Scott please trust me when I say this. Trust Derek," Emilia closed her eyes and returned to human before she was back standing with Derek.

"I can't trust him! He just wants to be stronger!" Scott yelled as he tossed Erica into the ice. "Don't you understand that?"

"Do you? Scott, just so that you are aware. Whenever there's a new wolf in town, that's not affiliated with a pack...pre-existing packs try and make them join," Emilia took a deep breath pausing as she felt Derek wrap an arm around her and pull her closer to him. "A pack makes not just the alpha stronger but each member,"

Emilia and Derek watched as Scott easily defeated Isaac and Erica, while Boyd stayed where he was sitting on the ice-tractor. A few minutes later and Derek was beating Scott while Emilia helped Erica and Isaac to their feet. Erica pulled her arm away from her, while Isaac nodded at her. Boyd hopped off the tractor and joined them walking away as Scott said that joining them was a bad mistake.

A few days later and Derek and Emilia were training Boyd, Isaac and Erica trying to get them to use their senses when they fought. Derek effortlessly tossed both Isaac and Erica to the ground each time they attacked. Erica thinking she had gotten the better of Derek when she launched herself at him and made out with him.

"Hey Erica, next time you want to kiss my boyfriend. Don't," Emilia smiled at her before throwing her on the ground seconds after she stood up.

"How did you..." Erica trailed off as Derek wrapped an arm around the older girl.

"She's been like me for a long time," Derek said before Emilia elbowed him in the stomach and then flipped him over her shoulder.

"Never piss off a pregnant werewolf," Emilia stated, knowing that the three teenage werewolves didn't pick up the lie in her voice earlier. "Or a former soldier,"

"Like she said," Derek muttered, grabbing her hand and pulling her down to his level. "Hey,"

Isaac, Boyd and Erica all groaned, they didn't want to know what was going on between the two of them. Derek and Emilia started laughing as she rolled off Derek onto her back and the two of them stood up. Isaac had taken to Emilia faster than the others and often opted to stay with her when something went wrong.

When it came to the first full moon with Isaac, Erica and Boyd – Derek and Emilia chained the three teenagers up. Emilia was glad that she had never needed to be chained up having the anchors in Laura and Derek. Erica howled as Boyd and Isaac held her while Derek put a spiked crown on her head, both teens saying that they were happy that it wasn't them. Isaac found an anchor in his father from before he started to abuse him, so he was able to help Derek when the others changed. That same night Lydia took Derek before Emilia could stop her, so she contacted Deaton and told him where to go.

"Deaton, I don't care that you're not particularly fond of Derek. Just find him and help him!" Emilia hissed down the phone before she hung up and her attention was back on the three teenagers.

"Em, what's going on?" Isaac questioned, he was the only one that was coherent, yet still transformed.

"One of your classmates just took Derek," Emilia stated crouching down in front of him as she put her hand on his shoulder. "I want you to concentrate on your anchor, it'll help you return to human,"

A short while later Stiles and Scott decided that it was time to introduce Emilia to their friends not just to Boyd, Erica and Isaac. Allison and Lydia, Lydia who Emilia vaguely remembered hearing about in a lot of letters from Stiles while she was away. Allison who the boys had told Emilia was the daughter of hunters; but she was their friend.

By the end of the first week of April, they had dealt with a kanima that turned out to be Jackson. Stiles and Scott didn't know whose side Emilia was on as she seemed to be helping both sides. Scott had worked out that Derek was Emilia's alpha, that much they knew. Jackson had changed his story so Isaac was no longer wanted for his father's murder. Noah and Melissa found out about the supernatural, though Noah was having a harder time dealing with it. Allison's mother died after being attacked by Derek for trying to kill Scott. Allison's grandfather turned her against her friends, against Scott – which didn't last long once she realised what he was up to.
