I know, another werewolf!Stiles fic. What can I say? I'm obsessed. This diverges from the canon from the moment Peter offers Stiles the bite in the season 1 finale. Due to that, Jackson doesn't get the bite, there's no kanima, no Gerard or anything.
"I like you, Stiles, since you've helped me, I'm going to give you something in return. Do you want the bite?"
Stiles, you just had to open his big fat mouth didn't you, Stiles thought. He was mentally berating himself even as Peter spoke.
"What?" No, he was busy thinking, he couldn't have heard that correctly.
"Do you want the bite?"
Nope, I heard it correctly then, he thought.
"If it doesn't kill you, and it could, you'll become like us," Peter said.
"Like you?"
"Yes, a werewolf, would you like me to draw you a picture? That first night in the woods, I took Scott because I needed a new pack. It could've easily been you. You'll be every bit as powerful as him. No more standing by his side, watching him become stronger, and quicker, more popular. Watching him get the girl. You'd be equals. Maybe more." He reached out to grab Stiles' wrist and bring it up to his mouth. "Yes or no?"
His teeth began to elongate, but Stiles ripped his arm from Peter's grip. "I don't wanna be like you."
"Do you want to know what I heard just now? Your heart beating slightly faster over the words 'I don't want.' You may believe you're telling me the truth, but you are lying to yourself." He turned toward his car. "Goodbye, Stiles."
Stiles sighed out of relief. Peter turned back to him.
"You know, because I'm such a giver, I'll still give it to you. I'll probably need some help tonight anyway."
"Uh, I said no, and even if you bit me, I wouldn't be any help. I wouldn't really be worth anything until tomorrow."
"Ah, that's where you're wrong," Peter smirked. Stiles tensed up and backed away.
Peter stalked forward and grabbed his wrist before chomping down. Stiles cried out in pain, his eyes started to water. Peter then wrapped his hand around Stiles' wrist. Blackness started creeping up his veins and Stiles' wrist felt tingly. The bite slowly began to fade.
"How the hell did you do that? Scott's bite didn't fade until the next day."
"Only an alpha can quickly heal injuries they give. If I slashed Scott, he wouldn't heal right away unless I did something about it. I bit you, so I can make it disappear faster. It will quicken the process of your transformation." Peter smiled but it was creepy. His eyed bled to red and his voice deepened, "now get in the car," he growled.
The bite worked because Stiles scrambled to obey. He ran around the car and climbed in. The smell of death hit his nose. His senses were already heightened because he could smell the nurse in the trunk.
"Why do you need me?" Stiles squeaked.
"If Scott has found Derek like I'm assuming, it'll be two against one. With you, it'll be two against two. Scott won't hurt you, so you can take care of him while I deal with Derek."
"What makes you think I'll help?"
"You won't have a choice. See, unlike Scott, you haven't been out of my sight since I bit you a few minutes ago. I'll have a bit more influence over you. Scott wasn't around me for days after I bit him so he was able to resist. You'll obey me. If not, I know a certain sheriff that may need a visit from me."
"You bastard," Stiles growled.
"Just wait, Stiles. You'll be thanking me."
They drove in silence for several minutes. Stiles' heart was thundering and he couldn't stop it. Peter probably thought it was hilarious.
Peter stopped on the side of the road and ordered Stiles out of the car. They walked through the woods for a while until the Hale house came into view from the back. Peter shoved Stiles in through the door and they could hear talking outside. Scott, Allison, Kate, and Chris. There was a fifth heart beat, but they weren't talking. It was probably Derek.
"Yes, Derek's down, but not for long. You are going to go out on that porch when I tell you to and attack Scott. I'll take care of Kate and Chris. The girl is no threat, I'm not going to harm her."
"Why are you doing this?" Stiles asked quietly and angrily.
"Revenge. Kate Argent is going to pay, but since Scott and Derek won't cooperate, I'll need to take care of them. I don't want to kill them, but it might come to it. I'm not that heartless Stiles. I just want you to hurt Scott, maybe you can even bring him over on my side. I'm not asking you to kill him."
Stiles looked unconvinced. Every time Peter told him to do something, he wanted to do it. Not deep down. Deep down, he wanted to fight it but he couldn't. Peter had some sort of hold over him. He tried to think.
"Peter?" Stiles asked. Peter looked annoyed and turned to him. "Is there a such thing as a sire bond?"
"What the hell is a sire bond?"
"Like on The Vampire Diaries. A vampire can have loyalty to the one that turned them."
"Vampires and television comparisons? Stiles, I figured you, of all people, would be above that, but since it's a good question I'll answer it. Yes, there is. That's not what its called though. I don't know the name for it, but it's a thing. You think you have this bond with me?"
"Yeah," Stiles muttered.
"Interesting," Peter said with a malicious grin. "I want you to go out on that porch right now. That's all. Don't do anything else. Only attack Scott when I give you the signal."
Stiles wanted to run out the back of the house, but his legs carried him to the front door. He hesitated and Peter glared at him. He ripped the door open and stepped out. The conversation or arguing or whatever was going on outside stopped. Chris and Kate turned their guns on him. Even Allison turned her bow on him.
"S-Stiles?" Scott asked. "What the hell are you doing here?"
Stiles didn't know what to say and he was shaking slightly.
"Kate, lower your gun. He's human, I'm not sure what he's doing here though," Chris said. He and Kate lowered their guns, Kate a little hesitantly.
"Stiles?" Allison asked lowering her bow. "A-are you okay?"
"Scott, I'm so sorry," Stiles choked. Scott just looked confused.
The howl, well, it was more like a roar, behind Stiles inside the house was his cue and he couldn't fight it. He launched himself at Scott and shifted as he dove. Neither Chris or Kate had time to draw their guns. Allison, however was terrified. Scott was her boyfriend and Stiles was her friend.
Before anyone could make a move, however, Peter, in full alpha form, shot out of the house knocking Chris and Allison to the ground. Kate's gun went off several times, but after a cry of pain and the snapping of a bone, she dropped it.
Scott and Stiles rolled around on the ground snarling and growling. Stiles was obviously trying to hurt Scott but Scott didn't want to hurt Stiles. He slammed Stiles into a tree and wrapped his hand around his best friend's throat.
"Stiles, what are you doing?"
Luckily Peter's control over him couldn't prevent him from telling Scott. At least not yet.
"Scott, I can't help it," he said shoving Scott's hand off. "He bit me after Lydia was attacked and did something to speed it up."
"But why are you helping him?" Scott spat and he threw Stiles to the ground.
"Remember that time we watched The Vampire Diaries and Elena had the sire bond with Damon because his blood turned her?" Stiles asked as he pulled Scott to the ground and rolled over on top of him.
"Yeah, why-" Scott froze. "Oh my God. You're joking."
"I'm not, and if I fight it somehow, he'll kill my dad. You have to kill Peter. It's the only way to make it stop."
Scott rolled the two of them back over. "Stiles, I'm sorry, but this is going to hurt bit." He lifted Stiles by the collar of his shirt and slammed his head into the nearest tree. It wasn't as hard as Scott intended it to be. Stiles just grabbed the back of his head.
Allison's scream from the house made them jump. Both rushed through the front door together. Kate was laying dead at Peter's feet. Derek was entering the room from the back, growling. Stiles remained behind Scott as Scott growled for Allison to run.
Allison bolted from the house and Scott and Derek both ran at Peter.
"Stiles, get Scott," Peter commanded.
Stiles tried to fight it. He really did. He grabbed Scott and slammed him into the piano in the corner. Piano keys and splinters of wood went flying everywhere. They rolled across the floor several times. Peter was busy fighting with Derek and smashing other pieces of charred furniture.
Scott threw Stiles through a boarded up window before jumping out after him. Stiles hit the ground two feet from Allison and her dad, who had just entered the world of the conscious again, and rolled.
"Scott," Stiles growled. "He'll make me kill you. Get Allison and her dad out of here. Tell them. They might help take Peter down."
"Be careful with him, okay? I'll tell Derek later."
"Fine, sorry about this," Stiles muttered. He was great a whispered conversations while fighting now. That's one perk of being bitten. Also, he and Scott weren't fighting every hard. He was just supposed to keep Scott busy. He tossed Scott into a tree and ran back into the house.
Peter was standing over Derek. "I don't really want to kill you, Derek. I'll leave you to think it over. Come, Stiles."
Stiles hesitated for a moment, but Peter snarled and he ran after him.
"What now?" Stiles asked as they ran through the woods.
"Now, I'll reward you by taking you back to your jeep and not making you run there. You can bend the keys back yourself. You will stay inside the rest of the weekend unless I call for you. Monday, you will approach Scott at school and try everything in your power to get him to join me."
"How do I do that?"
"God, Stiles you're smart. You'll think of something. Threaten to personally kill his mother. Lovely lady, but its worth it."
"She's like my mom," Stiles cried.
"I said threaten and if she has to die, I won't make you do it. I could force you to murder your own father, but I won't because you've done well tonight."
"Thanks, I guess."
When Peter dropped him off and he climbed into his jeep. After carefully bending the key back into place, he headed home where his dad was. The moment he walked in the door, his dad rounded on him.
"Where have you been, Stiles? Do you know Lydia Martin, the girl you took to the dance, was attacked on the lacrosse field?"
He decided to play dumb. "What?" His dad bought it.
"Stiles where have you been?"
"I was at the dance with Lydia and she refused to dance with me. Finally I got her to and it was good. Then the next thing I knew, she was saying "I need to find Jackson" and then she left me. I didn't want to stay and look dumb, so I left. I just went for a drive."
"Why are you dirty?"
"I went for a walk in the park and because I'm an idiot, I tripped and fell in the dark. Dad, please can I just go to bed? I'm exhausted and you telling me about Lydia has just added to it."
"Sure, I'm just glad your safe. And no more walking around the park after dark. Not only will you get hurt and have no one find you until the next day, its illegal, the park closes at sunset."
"Sorry, I was just upset over Lydia basically dumping me to find that douche."
The part where Peter quickly heals Stiles' bite was for the sake of the story and keeping it semi canon. All of that happens in the same night, and if Peter had bit Stiles, he wouldn't be a werewolf until the next day. Peter needed Stiles that night, so I just created that to make that possible.
