A/N: Finally Part 2. Warning for language and violence I guess.

***

"Don't you think there might be a better way to do this?" Derek asked as they rode the elevator up to the floor where the alpha pack had taken up residence.

Peter tilted his head from side to side stretching the muscles in his neck. "Oh, I'm positive there's a better way to do this, but I'm not leaving Y/N in there any longer than I have to."

"So us storming in there and getting ourselves killed is going to help her how?" 

Peter glared at his nephew. "I don't know, okay? I don't know anything except for the fact that she's in there right now scared out of her skull and thinking I don't give a shit about her. I told you not to come."

Derek shrugged as the elevator came to a stop. "And I told you that I'm doing this for her. Not you."

Peter grunted as he made his way quietly down the hall. "Yes. You keep telling me that. I think I get it." The rest of the pack was scattered throughout the building. Even the Argents had agreed to help. Though they too made it clear they were doing it for Y/N not him. Whatever. He didn't care as long as his mate was rescued. 

He took a deep breath as he came to the door. He knocked loudly and shifted his weight on his feet as he waited for someone to answer. The door swung open and that bitch Kali stood smirking at him.  "Can I help you?"

"You took something that belongs to me. I want it back," he answered. 

Her eyes widened along with her smirk. "That must make you the mate. Oh, Deucalion will be so pleased you are here." She gripped the front of his shirt and pulled him into the apartment. He spotted Derek stumbling through behind him, just before the door slammed shut.

"What's with the noise?" Deucalion asked and Peter straightened his stance. 

"The mate is here," Kali said, that ever present smirk still on her face. 

The blind werewolf sniffed the air then came to stand in front of Peter. "Why does it come as no surprise to me that you're the one that fucked everything up?"

Before Peter could respond, something hit the back of his head and he blacked out.

The pain was the first thing Peter was aware of as he began to wake. They must have hit him hard for it to still be hurting. Damn it. He groaned as he lifted his head and squinted against the glare of the lights. He was a little surprised to find himself still in the alpha apartment, though now he was chained to a chair. Derek hung from chains bolted to the ceiling on the other side of the room. At the moment they were alone.

"Have you seen her?" Peter asked. 

Derek's dark eyes studied his uncle then he shook his head. "No. You know when you called her your mate I thought you were speaking figuratively."

"Yeah, well, I wasn't."

"Then why did you say what you did this morning?" Derek questioned with a bite to his tone. "Surely you don't feel that way if she's your mate."

Peter ran his tongue across his teeth as he thought about what answer to give. Finally, he decided the truth was the best option. This was Derek after all. "I didn't want any of you using her against me. I didn't want her put in danger."

"Do you really think we'd do that?" Derek almost shouted.

"What reason did I have to think you wouldn't?" Peter snapped back. 

"Well, it's Y/N for one thing."

"Hate to interrupt, but we have some unfinished business," Deucalion said as he stepped out of a room and shut the door behind him. 

Peter struggled against the chains. "Where is Y/N? What have you done with her?"

"She is alive. For now." The alpha of alphas sat in a chair between the two Hales. "Do you have any idea what she is? How special she is?"

"Of course I know how special she is," Peter bit out. He was horrified to realize his eyes were tearing up. 

The other man laughed, a harsh sound. "You have no idea. You stumbled upon her by dumb luck." There was a stretch of silence until he tilted his head to the side with a little smirk. "However, I know precisely what she is and I'm afraid I can't allow you to keep her."

"Sorry to break it to you, but they are already mated," Derek said. "You can't just take his place."

"No, but I can kill him." Everything Deucalion said was in the same even tone. It only made the man that much creepier. 

"So kill me already."

"Not just yet." He pursed his lips. "You see in order for Y/N to reach her full potential, in order for her to help me reach my full potential, she has to be one of us."

Peter's gaze darted to the door the alpha had come through moments before. "Please tell me you didn't," he all but begged in a quiet voice. The thought of his Y/N behind that door in pain and possibly dying made it hard to breathe. 

"Oh, but I did." A smile curled his lips. "If she survives the bite, I'll kill you myself. If she dies, well Derek here can kill you and you'll even welcome it won't you? And he'll take another step to becoming one of us."

"Just let her go," Derek bit out. "Do what you want with us, but let her go."

"Allow me to enlighten you gentlemen about what precisely we are dealing with here. Y/N is a true mate."

Peter's eyes widened. It wasn't possible. "That's a myth, a legend."

"Is it?" Deucalion asked in a tone that made it clear he considered it neither. 

Derek shot a questioning glance at his uncle. Peter cleared his throat. "What makes you think Y/N is a true mate?" 

"She has all the signs, Peter. I'm surprised you didn't notice them before." And there was that maddening smirk again. 

"And what are these supposed signs?" Derek asked. 

"First and foremost, the true mate is a peace bringer. She is normally universally liked. Can either of you think of a single person that doesn't like her? No matter how lovely someone is there is always one person that hates them. It's just the way of the world. Even Kali likes her and Kali doesn't like anyone."

"Okay, I'll give you that one. What else?" Derek asked. 

"No wolf will harm her, even if they are crazed and fully turned," Deucalion said, turning his head slightly in Peter's direction. 

Peter swallowed and nodded once to tell Derek it was true. As much as he loved her, he had always thought it slightly odd he hadn't bitten her that night in the forest. 

"And the power." The alpha said the last word with a lustful tinge and Peter's lip curled in disgust. "So much power. There's only a hint of it now, but when she is one of us...oh, there will be no stopping her. Or her mate." He stood then and began to pace the floor. "For that is her purpose, to empower her mate. And then of course, there is the final sign. Peter, would you care to confirm its existence?"

He clenched his teeth together to the point his jaw ached. "True mates have a birthmark shaped like a wolf's head on their hip. Sorry to disappoint, but I wouldn't know if Y/N does or not. It didn't occur to me to search her for mythical markings while we were making love."

Deucalion stopped pacing and smiled over his shoulder in Peter's direction. "Well, we examined her quite thoroughly and I can assure you she does."

"You son of a bitch," Peter spat out and pulled against his chains again. To his surprise, he felt them give. He could break free. With the knowledge, he quit struggling. He needed a plan first. He would only have one shot at this. He couldn't waste it.

The sound of a door opening drew his attention and Peter turned to see Kali coming from the same room Deucalion had exited earlier. "What's the verdict?" the alpha asked in a hopeful voice.

"She didn't make it." 

The shewolf's words pierced through Peter like a silver bullet to the heart. This was his fault. He should have gotten her away from here. Taken her anywhere but Beacon Hills which seemed to be the epicenter for all the supernatural drama in the world. Maybe if they'd left, they wouldn't have found her. Maybe she wouldn't have felt the need to sacrifice herself for her friends. 

His chest was tight and he struggled to suck in a breath. A day. He'd had her for a day and already lost her. His grief was a heavy, palpable thing. Deucalion was right. He would embrace death now. He would welcome it with open arms. If this horrible, aching pain was what it felt like to live without her, he wanted it to end now. 

Deucalion threw a chair across the room and shouted in frustration. He stormed over to Peter. "This is your doing," he growled.

Peter nodded though he knew the other wolf couldn't see it. He looked up at his would be executioner, his face wet with tears. "You're right. This is my fault. Kill me."

When Deucalion just stood over him breathing heavily, Peter shouted the words again. "Kill me!"

"I would prefer if you didn't," a sweet, familiar voice said and everyone turned to find Y/N in the doorway behind Kali. 

Peter laughed in relief, his breath coming in a shudder. She was alive. Fresh tears ran down his face, but now they were of relief and happiness. His Y/N. His true mate.

Kali reached out for Y/N's arm and her hand flashed out too fast for Peter to even follow the movement. In the next instant, Kali was laying on the ground and Y/N was dropping the woman's heart on her corpse. 

She didn't even glance in his direction as she prowled across the room to Deucalion. He stood in front of her in awe and it was easy to forget for a moment that the man was blind. He lifted a hand and touched Y/N's cheek. The power that radiated from her seemed to have him enthralled. "You forgot something about true mates, alpha of alphas."

"What is that?" he asked. 

"We bring peace by whatever means necessary." She punched into his chest and Deucalion gasped as he bent forward. "And we protect our pack, especially our mate, above all." With those words she removed his heart as well. 

Y/N dropped to her knees, her bloody hands in front of her. Tears ran down her face. Peter pulled against his chains in one swift movement and they clattered around him. He easily snapped the ones from his legs as well and hurried to his mate. 

He slid onto the floor next to her and pulled her into his chest, holding her while she wept. They stayed that way for several minutes until one of her legs lashed out, kicking the alpha's corpse. "Asshole."

Peter leaned back with a smile and cupped her face in his hands. Using his thumbs, he wiped the tears from her cheeks. "There's my girl," he said with a smile. When she just looked back at him without saying anything, his smile fell. "I love you, Y/N. So much. What I said this morning was to protect you. I didn't want anyone using you to get to me."

She shook her head and rolled her eyes. "I don't think you need to worry about that anymore. I can just rip out the hearts of anyone that pisses me off apparently."

Peter glanced at the body beside them before looking back to her. "I would really appreciate it if that wasn't your first reaction. Given my track record, I'm likely to piss you off a lot." He smiled though he was certain it looked more like a grimace. 

"Um...do you guys think you could release me now?" Derek asked as he shook the chains on his wrists. 

"We'll think about it," Peter said as he pulled his mate back into his arms.
