Nicholas was standing in the middle of the clearing when Stiles finally made his way through the dense forest.

"So you finally want to help me?"

"He thinks he can threaten me and think I will just stand by and let him get away with it. I am ready to put a stop to this once an for all."

"Well you know we are only going to have one shot at this right. Not only is he alpha, but he is a born wolf, who is older. He will know what he is doing. Are you sure you don't want to ask Derek to help us on this?"

"Derek stays out of this, as does the rest of the pack." Stiles thundered out.

"Well then I guess it's a good thing I got back up." Nicholas motioned behind him and Issac came out from behind one of the trees.

"What is he doing here?" Stiles questioned.

"He is here to help. He hates Peter almost as much as I do and he is also the closet to Peter, per their "special" relationship." Nicholas answered.

"What do you mean "special" relationship?"

"He means Peter fucks me." Issac hissed out.

"Oh...well then, I can see why you would hate him."

"So let's go over the plan one more time and then plan for attack tomorrow night." Nicholas stated. The three boys huddled close together and talked well past the sun coming up. They had to put the finale pieces together. Once they were sure they had a more stable plan Stiles made his way back to his dad's house to set it all in motion.

"What do you mean that you are leaving?" the sheriff was standing in Stiles' doorway watching as his son gathered most of his belongings into his pack.

"It's the best thing for me dad. Derek has Danny and Bryce and I need to finish up school. Away from here." Stiles couldn't look at his father, he knew that if he did he wouldn't be able to go through with the plan. He had a lot riding on this, he just had to make his dad believe that he was...

"Were the hell do you think you are going?" Stiles was interrupted from his thoughts when Derek came barreling into the room.

"Derek, what the hell are you doing here?"

"Answer me Stiles, where do you think you are going? You just gonna up and leave without so much as a goodbye? You're just gonna leave your dad, the pack, me? Again."

"Derek..please you don't understand." Stiles tried to pull Derek's face into his hands but the older man pulled from his grasp.

"If you leave then that's it, don't ever come back. You aren't welcome here anymore."

Stiles stared at Derek seeing the truth behind his anger. Stiles let out a soft sigh and turned back to his bed grabbing his bag. This was what was best for everyone.

"Goodbye Derek." Stiles whispered and made his way out the door and outside to his jeep. He knew it was all part of the plan, but that didn't make it hurt any less.

Derek slams his way into the apartment. Fury rolling off of him that the rest of the pack is choking on it.

"Derek, what's wrong?" Danny come out of Bryce's room the banging catching his attention.

"Stiles is no longer welcomed here." Derek stormed his way up the stairs and slammed his door with a final statement.

"What the hell?" everyone questioned at the same time.

Scott made his way out of the house and raced his way over to the Stilinski's house.

"What is going on?" Scott asked the sheriff once he opened the door.

"Stiles left. He said it was too much and he wants to go back to school. Derek kicked him out, saying he wasn't allowed to come back."

"What the hell, Derek can't do that. Everything was finally coming together. They even slept together."

"Well I didn't need to know that Scott. I don't know what to do any more. He is an adult and if he wants to leave, well unfortunately I can't stop him."

Both men just sat there lost in their own thoughts wondering what was gonna happen next.

Stiles was driving when his cell went off.

"What"

"Stiles, is that any way to answer the phone?" Peter chuckled at him.

"What do you want Peter?"

"I heard you were leaving, just wanted to say goodbye and say you made the right choice."

"It's not like I really had a choice though is it, I mean it's either leave and have everyone hate me or stay and lose everyone by you killing them. At least this way I may have lost them but they are still alive."

"Aww yes I heard my dear nephew told you that you were no longer welcomed back here, but if you ever want to visit, just let me know and I will make sure you aren't bothered. Bye Stiles, and good luck." Peter let out another chuckle as he hung up.

Stiles was seething with anger that he almost broke his phone before he reigned in his emotions. It was time to put Peter down once and for all.

TWTWTWTWTWTWTWTWTWTWTW

Nicholas had just gotten off the phone with Issac when he saw Stiles pulling up.

"How did it go?"

Stiles just glared at the him.

"I see it went well." Nicholas joked. Stiles just glared back even harder. "Alright, enough of the jokes. I just got of the phone with Issac. he said that Peter and him are supposed to go out to dinner tonight and then go back to their place for a "nightcap" if you catch my drift."

"Great well then we know what we gotta do." Stiles said and Nicholas smirked. This might actually work.

TWTWTWTWTWTWTWTWTWTWTW

Of course the plan doesn't work. When does it ever work? Not only did the plan fail but now Nicholas was laying in a very large pool of blood that Stiles didn't think he was going to be healing from.

"Stiles do you really think you can beat me?" Peter chuckled as he spit up a little bit of blood.

"Of course I am going to beat you. There was never any doubt to it. I will end you Peter and then I will take over your pack." Blood was dripping down Stiles side were Peter had raked his claws. There was blood in his eyes that he had to keep whipping from the claw mark on his forehead. His arm was broken and just hanging there and he was dragging his left leg since Peter had taken a chuck of his calf. Stiles didn't know how he was going to end Peter, but he knew he had to try.

Peter walked over to Stiles and tackled him to the ground. As he was sitting on top of him gearing up to give the final blow everything seemed to move in slow motion. Issac came out of his hiding place and in super slow motion stabbed Peter with the blade he had hidden. Peter gasped and slowly fell off Stiles' body. Issac stood of Peter and lifted his claws in the air and came down with the killing blow. He turned to face Stiles, his eyes glowing a fiery red.

"Issac." Stiles whispered. Stiles struggled to get up and make his way over to Issac. By the time he reached the other man Issac had fallen to his knees shocked at what just happened. Stiles could see the internal struggled Issac was going through and pulled him to his chest. "Issac, it's going to be okay. You are going to be okay. We gotta get Nicholas to Deaton, he can help." Slowly Issac made his way to his feet and they both walked over to Nicholas.

"I am sorry I didn't let you kill him Nic." Issac whispered.

"Its okay, I am just glad he is dead." Nicholas started coughing, blood flying everywhere.

"We gotta get you to Deaton." Stiles said.

"There isn't anything he can do to help me Stiles. I am not making it out of here but at least I know everyone is finally free of him. Issac you take care of Erica and Boyd, don't let the power control you like it did Peter. You are better than that."

"I won't. I am so glad I met you Nicholas. I will never forget you." Issac was fighting back tears.

"Stiles don't let anymore time pass between you and Derek. You deserve a happy ending and he is yours."

"I promise." Stiles choked out. Nicholas slowly closed his eyes and let out a final sigh. Stiles sobbed as Issac pulled him to the car and made his way to the animal clinic. On his way he called Erica and Boyd and told them to meet him at the clinic and then he called Derek and told him the same thing.

TWTWTWTWTWTWTWTWTWTWTW

By the time the cuts healed and his arm was no longer broken, the two packs had finally arrived. Scott was the first to burst into the back room. Running over to Stiles he pulled him into a tight hug.

"Stiles what the hell happened? I thought you were leaving us."

"I know buddy. I had to make you all believe I was leaving for the plan to work."

"What plan?"

"I killed Peter and became the alpha." Issac spoke up from the corner he was standing in.

"You did what? Why would you do that?" Erica voiced as she made her way into the room. Issac just glared at her and flashed his eyes once to shut her up.

"I did it to set us free, we are no longer under his control. We can actually live."

"Were's Nic?" Boyd questioned.

At the mention of his name Stiles started to silently cry and Issac looked down while shaking his head.

"He didn't make it." Issac whispered out.

Erica and Boyd went to Issac and drew him in. They all silently wept for their fallen pack member.

Everyone slowly made their way out of the exam room leaving only Stiles and Derek who just silently stared at each other.

"I am sorry." Stiles began.

"Don't, not right now. I don't want to hear it. I am just glad you are okay. Just come home with me and we can talk in the morning when we all have calmed down and had time to let this all sink in." Derek held out his hand and Stiles lifted his to grab it. In that moment he knew it would all work out.
