Chapter 4 - Full Moon

"Erin would you come in here," Stiles bellowed throughout the house. Erin was in the kitchen and heard him as if he was standing beside her. Erin climbed up the stairs and knocked on Scott's door, but didn't enter until Stiles told her to do so.

"You hollered, Master?" Erin curtsied before him.

"Master," Stiles said amusingly and gave her a wink. "I like it." He shook his head, trying to remember why he had called her upstairs. "Would you tell your brother to get a grip?"

Erin looked at Scott who was still lying in bed at 12:47pm; he was not handling the break up with Alison too well. "Come on dude, he's right." She sat on the edge of the bed. "Get up, go out, and take your mind off it."

"I don't want to take my mind off it," Scott said.

"This isn't healthy."

Scott sat up in his bed, but made no attempt to get out of it. "You love this don't you?" Scott spat at his sister "This is exactly what you and Derek wanted."

"No, Scott. I don't like seeing you like this," Erin furrowed her brows at Scott's bizarre behaviour. This wasn't like Scott. "I don't like seeing you hurting, but I'd rather you have a broken heart than a broken neck!"

"What would you know about relationships? Your last boyfriend cheated on you!" Erin looked confused. How did Scott know that? She didn't need to ask him about it. He answered her unasked question. "I've heard you on the phone and you're practically in love with a guy you barely even know."

"Scott, you're…"

"On second thought," Scott said, jumping out of his bed. "I will go out." He slammed the door to his bathroom.

Erin turned to look at Stiles. He held his hands up as if she were holding a gun to his chest. "I don't know. Full moon maybe?"

"He just doesn't get it does he?" Erin stood up and spoke knowing Scott could hear her. "I know he loves Allison, but there are going to be other girls. You two may not be the 'popular' guys right now, but I promise you and Scott will marry some pretty, amazing women and that Jackson guy will end up in jail or dead!"

Stiles reminded her. "We've still got our deal."

"As always," Erin smiled. When Stiles had turned fifteen, he had made Erin promise (and sign a contract, written on a napkin) that if by the time she were thirty- if she were not married-she was to marry Stiles.

Erin knocked on Derek's door and waited for a response, however; she didn't expect one. It had been five days since the school incident and Derek practically threw her out of his house after she had saved his life again. The door didn't open even after the third time she knocked; no one had seen or heard from Derek.

"Screw this" she tried the door handle and it opened. Guess you don't need to worry about security if you're a werewolf, she thought to herself.

"Derek," she called, but again expected no reply. "Derek, if you're in here please answer me…" Erin walked further into the house and closed the door. She didn't want to go snooping around so she closed the door and stood at the bottom of the stairs.

"I guess if you are in here you can hear me wherever you are so here goes. It's the full moon tonight, which you know I guess," she paused, not sure if she wanted to admit this. "I'm scared Derek. I have no idea what's going to happen. How I'm going to stop Scott from hurting someone like the Alpha wants? Scott needs help, he needs your help. We all do. I don't want to have to shoot my brother with tranquilizer!"

She sighed loudly. The last thing she wanted was for Derek to see her get all choked up. "If you can hear me then, please come to the house tonight and help me." She paused again "I guess what I'm trying to say is I need you, Derek."

She put her hand on the door handle, glancing around the house again for movement. The last thing she said was a quiet "I need you".

"Please let me out," Scott pleaded from his room. Stiles and Erin were trying to ignore him. Stiles had handcuffed him to the radiator after successfully pushing his doubts aside. "It's the full moon, I swear," Scott assured them. "You know I wouldn't do any of this on purpose. Come on, you know me."

Erin and Stiles sat next to one another in the hallway "I can't take this," Erin whispered. Stiles had already told Erin about Scott making out with Lydia when he should have been asking her if she liked Stiles. Erin had let Stiles giving Scott water in a dog bowl slide for the simple fact she knew Stiles was obsessed with Lydia but she told him he was allowed to do no more.

"Just let me out," Scott begged them.

"We can't," Stiles said softly. "We don't have a choice." Stiles was talking to Scott, but his focus was on Erin. Carefully, he took her hand. "We're not letting him out. Did you try Derek again?"

"Yes, Stiles. I tried Derek every day for the last 5 days. He either skipped town or is avoiding us."

"Why is he avoiding you?"

"He's not avoiding me!" She exclaimed. "He's avoiding us!"

"Well, you saw him last...and you're the one who spends all your time with him," Stiles inquired.

"We do not spend all our time together!"

"Oh come on, yes you do. He picks you up from work. You even run together."

"He's the only person I can talk to about all of this." Stiles pointed to himself "I mean, only adult I can talk to!"

"I just don't get it, what happened after the Alpha thing?"

"We've been over this! I told him what had happened, he got a bit freaked when I told him he had started to change and he threw me out."

Stiles growled in anger and annoyance. "The one time we need him and he's not here."

"We'll get through this. We just gotta not listen to it," Erin told him, referring to Scott's protests.

"So...you said I was cute," Scott said, changing the subject.

Erin laughed. "Yes, Stiles. You're cute, but so are puppies"

"And werewolves."

"What's that supposed to mean?"

"Come on Erin. Scott and I have both noticed before the night at the school you and Derek were getting close. Did he confess his undying love for you and you turned him down?"

"Don't be ridiculous." Erin slapped Stiles on the arm.

"Ow," Stiles complained as Scott began to panic in the other room. Erin went to stand up, but Stiles put his hand on her arm and made her sit down again.

Scott began to scream and Stiles put his hands over his ears and Erin copied him. Erin began to cry and Stiles put his arms around her and held her closer to him. "It's ok, it's ok. It will be over soon," he whispered soothingly to her.

Silence.

"Scott?" Stiles called. "Are you okay?"

No reply.

"Scott?" Erin asked. They stood up quickly and went into the room. The handcuffs lay on the floor. Blood stained the floor beside them, but no Scott.

Stiles stated the obvious. "Holy crap, he got out."

"Shit." Erin began to cry harder

"I'll go after him," Stiles told her. "Stay here in case he comes to his senses and comes back."

After he finished speaking, he rushed out of the room to begin his search for his best friend.

Erin paced up and down in Scott's room in front of the window. She had cleared away the handcuffs and cleaned up the blood. Stiles had called to ask her where she thought Scott would go and the only thing she could think of was Alison. If Stiles found Alison, she was sure Scott wouldn't be far.

"Erin," a familiar voice called her name. She raced out of the room to find Derek helping Scott walk. Derek assisted Scott to sit on his bed.

"Thank God! Are you okay?" Erin began to check Scott over for injuries.

"Wait," Scott told Derek as he began to walk out of the door. He stopped and slowly turned around.

"I can't do this. I can't be this and be around Alison," Scott began Erin moved to sit on the bed beside him. "I need you to tell me the truth: is there a cure?"

Erin looked at Derek who looked at her. They had agreed not to tell Scott. Not unless he asked. "For someone who was bitten, I've heard of one. I don't know if it's true or not," Derek told him shaking his head.

"Well, what is it?"

"You have to kill the one that bit you." Derek didn't even try to sugar coat it for Scott.

Scott looked like he had been shot down. "Kill the Alpha?" Derek nodded.

"How? We don't even know who it is!"

Derek stepped closer to the bed and spoke directly to Scott. "If you help me find him, I'll help you kill him."

Erin closed Scott's door as she left him to sleep. Derek walked down the hall and down the stairs. Erin followed quickly behind him. "Derek, wait, please" she said as he opened the front door.

He stopped but didn't turn around, Erin stood at the bottom of the stairs, and tears began to form in the corner of her eyes. "I don't know what I did that day," she paused to catch her breath. "Please Derek, I can't do this on my own and neither can you." Derek turned to look at her but didn't speak. She walked closer to him. "You need us too whether you admit it or not. You've been in this on your own for a long time and its time you let us help"

"It's dangerous. You shouldn't be involved"

"I already am involved. I don't want anything to happen to Scott or you. I wouldn't forgive myself if something happened to either of you. I know you don't trust me and that's fine because I can't honestly say I wouldn't give you up if it meant helping Scott but we're all each other's got." Erin stepped closer to him again. "Please stay. Watch Scott and I promise no more Twilight related questions." Erin watched as Derek registered all she said. She watched as his lips twitched, trying not to smile. Erin reached around him and closed the door.

"For the record," he said and began walking towards the stairs. "You shot me twice."

She knew he had heard her when she had gone to his house. Erin picked up the phone and called Stiles. Stiles said he would be right over and he made a quick joke before she hung up the phone. She waited for him to arrive then went to bed.

Erin lay in bed thinking of Derek in the next room, wondering if he was thinking of her. She had missed him, thinking about it she realised how much time they spent together. She couldn't count the amount of times he had shown up at her work with food and spent the evening with her whilst she worked late, they had bumped in to one another whilst running and then every day since they had run together, without arranging it they would meet up in the same place every day and jog together, sometimes talking, other times just running. Then there was the kiss they shared when Erin's ex had shown up, she licked her lips remembering the tingling feeling his kiss had left. She hadn't seen him since he had practically kicked her out of his house and now he was asleep in the next room...she knew she wouldn't be getting much sleep.

A/N: Would really appreciated some reviews. What am I doing well? What could be improved on?

As always thank you to my beta - Velvet Light :)
