Code Breaker:

Kristie opened her eyes to a blurry scene before her. She had passed out last night because of what Kate did to her. She tried to move, but found that she was taped to a chair. Kate must have taken her. Her mom and Scott were probably freaking out since she didn't come home last night.

Kristie turned her head and saw the blurred image of Kate sitting in a chair. "Look who's up." she said. "Sorry about the black out. Humans don't normal take well to electricity. Well," Kate stood up. "Neither do werewolves." Kristie's vision cleared enough to see Kate shine a light on Derek.

His head was slumped, but he began to stir. He looked very pale and sweaty and beat up. "Derek." Kristie softly said.

He looked up at her. "Kristie?"

"Yes Derek." Kate said. "I caught your little girlfriend. And I think I did it at the right time. Doesn't she look pretty?" Kate looked at Kristie, motioning to her dress and heels. "Well aside from the sweat and the sickly pale skin, she looks like she's ready for a night on the town."

"Leave her out of this." Derek said through clenched teeth.

"Oh baby. She deserves to know the truth."

"What truth?" Kristie asked.

"The fact that Derek and I used to be together. And by be together, I mean, we had crazy hot sex."

"Kristie, don't listen to her." Derek said.

"Don't lie to her Derek. She deserves to know before you to jump in bed together. Did he sweet talk you, Kristie? Did he say your the one...his mate?" Kristie looked up at Derek with a hurt expression.

"Kristie, don't listen to her. All of the stuff I told you was true."

"Oh, course it was." Kate said sarcastically. "That's why you'll be pissed when I do this." Kate turned a dial and Kristie felt the shock hit her like a ton of bricks. It only lasted for a second, but it was a painful second.

Derek growled at Kate and bared his fangs at her. "Stop it!" he yelled. Kate smirked, and then, her phone went off. She looked down at it. "I have to go. But I think I've left you with a lot to talk about." Kate walked out of the room, shutting the door.

Kristie kept her head down, not looking at Derek. "Kristie?" Derek asked. "Kristie, please talk to me."

"About what?" Kristie said, her voice cracking with tears.

"Kristie, Kate was lying."

"About what? The sex or what you said to me?"

Derek sighed. "When I was in high school, Kate and I were in a relationship, but I never told her the things I told you. Kristie, you are my mate. You are the only person I think about being with right now. I can prove it."

"How?"

"You know when we first kissed and I said your eyes were beautiful?"

"What? Were you lying about that?"

"No. Your eyes are beautiful. Everything about you is beautiful. But that was the first time I knew you were my mate. When I kissed you, your eyes flashed gold, like a werewolf's."

"But yours are blue."

"Mine are different. It's...It's a family thing. But that's how I knew. And then I started wanting to see you more and make sure you were okay and I just wanted to be around you."

"Look where that got us."

Kristie passed out a little while after their fight. She was just too tired and too stressed to try to stay awake. What Kristie didn't know was that Derek looked at her the whole time she was asleep, watching her chest move up and down, making sure she was breathing, making sure she was alive. Kristie woke up when the large metal door opened.

"Wakey wakey you two love birds." A bald man said as walked over to the two. "Listen, Katie got a little caught up, so she told me, I get to do the torturing." He cracked his knuckles. "And I can't wait for this." The man smirked, and then threw a punch landing it in the center of Derek's stomach. Derek winced in pain. He threw another punch in the same area then proceeded to punch his other place. He even shocked him a few times.

By the time tears started flowing, Kristie couldn't take it. "Stop it! You're hurting him!" she yelled. The bald man turned to her sharply. He walked over to Kristie and slapped her across the face and then grabbed it forcefully to look at her.

"Listen here little girl. I may be hurting him, but think of all the people he hurt, all the lives he's taken because of what he is. You may have this little infatuation with him, but it wouldn't ever work out. He would probably just end up killing you."

"Leave her alone!" Derek groaned. The bald man smirked.

"You know my hands kind of hurt after all that. I'll be back in a little bit with another means of torture." The man left the room, leaving a broken Derek and Kristie.

Derek passed out a little while later. The two hadn't talked while he was still awake. After Kristie knew he was out, she began to try and break free, so she could grab his phone and call Scott to come and rescue them. Kristie pulled and tugged and tried to get free, but it wouldn't work.

"Don't bother." Kristie looked up and saw Derek. He was awake. "I don't want you to get hurt." Kristie sighed and gave up. Derek lifted his head and had a look on his face like he heard something.

"What is it?" she asked.

"It's Scott." he said, and then let out a long, loud howl. "He's coming for us."

"Ready to have some more fun?" the bald man asked, walking into the room. He grabbed Kristie's face and smirked at her. Derek let out a low growl. The man let go of Kristie and walked over to Derek. "To be honest, my knuckles are kind of hurting." He held up a wooden at. "So I brought some help. But I need to warn you. I used to play in college."

The man swung the bat, but Derek caught it with his right hand. "I brought a little help to." he said and looked behind the man. The man turned and saw Scott standing in the doorway. Derek punched him into the wall, knocking him out.

Scott ran over to Kristie and began to untie her. "I'm so glad to see you." She said. He smiled and held up a pair of Kristie's combat boots.

"I figured you'd want better shoes." Kristie smiled at him and hugged him when she was free. She put the shoes on, thankful to have those heels off.

"Scott, help me with this." Derek asked as he ripped the wires off his body.

"No." Scott said. Kristie looked up.

"What?" Derek asked.

"Not until you tell me how to stop Peter."

"You really wanna talk about this right now?"

"He's going after Allison and her family. He's going to kill them."

"So what?"

"So, tell me how to stop him."

"You can't."

"Scott." Kristie said. "Come on. We don't know when Kate's gonna be back."

"Scott, get me out! Get me out right now!"

"Promise you'll help me."

"You want me to risk my life for your girlfriend, huh? For your stupid little teenage crush that means absolutely nothing? You know nothing about love Scott! You're not in love Scott! You're 16 years old. You're a child."

"Maybe you're right. But I know something you don't. Peter said he didn't know what he was doing when he killed your sister, right? He lied." Scott pulled out a piece of paper from his pocket and unfolded it. It was a report, with a picture of a dead deer on it. "Remember this? This is what brought your sister back to Beacon Hills, right?"

"Where did you get that?"

"Me and Kristie's boss told us three months ago someone came into the clinic asking for a copy of this picture. Do you wanna know who it was? It was Peter's nurse. They brought your sister here so that Peter could kill her and become the Alpha and that's why you're going to help me." Scott turned and started to walk away. "Just say you'll help me, and I'll help you unlock your other-"

The sound of crunching metal made Scott turn back around. Derek had broken his other restraint. "I'll help you." Derek said.

"Hold on. Hold on." Derek said as the three started to walk up the hill towards his house. Derek breathed heavily and started to look around. "Something doesn't seem right."

"What do you mean?" Kristie asked.

"I don't know...It was kind of like it was.."

"No don't say to easy!" Scott yelled. "People say to easy and bad things happen. What, do you think finding you two was easy? Getting away from Allison's dad? None of this has been easy."

"Fine your right."

"Thank you." Scott breathed out.

Suddenly an arrow shot through the air and hit Derek in the shoulder. "Derek!" Scott and Kristie looked around and saw Allison and Kate at the edge of the hill. Allison shot Derek again in the leg. Kristie ran over to Derek and pulled the arrow out of his leg.

"Scott your eyes!" Derek shouted as an arrow shot into a tree and blasted a bright flash of light. Scott dropped to the ground. Derek pulled the remaining arrow out of his shoulder, and stood. "Come on." he told Kristie, helping her up. The two grabbed Scott and ran towards Derek's house.

The three fell to the ground as Kate and Allison started to walk towards them. "Allison I can explain." Scott said.

"Stop lying." she replied. "For one stop lying."

"I was gonna tell you the truth at formal. I was gonna tell you everything. Because everything that I said, everything that I did-"

"Was to protect me."

"Yes."

"I don't believe you."

"Thank God." Kate groaned. "Now, shoot him before I have to shoot myself."

"You said we were just gonna catch them." Allison said, confused.

"We did that. Now we're gonna kill them." And Kate shot Derek. Kristie screamed and crawled over to him. "See? Not that hard." Kate walked up to Allison and looked at her. "Tsk, I know that look. That's the "you're gonna have to do it yourself" look. Tsk." And she pointed the gun at Scott."

"No!" Kristie yelled.

"Kate, Kate, what are you doing?" Allison asked. Allison tried to grab the gun from Kate, but she pushed Allison on the ground.

"I love those brown eyes." Kate said.

"Kate." All heads turned to see Chris Argent walking towards them. "I know what you did. Put the gun down."

"I did what I was told to do."

"No one asked you to murder innocent people. There were children in that house, ones who were human. Look what your doing. You're holding a gun to 16-year-old boy and you'll probably do the same to his sister, with no proof they have spilled human blood. We go by the code...Nous chassons ceux qui nous chassent."

"We hunt those who hunt us." Allison and Kristie both said under their breaths. Kate clicked the trigger on her gun and Chris held his gun up to her.

"Put the gun down." Chris said. He shot the gun, hitting a tree behind Kate. "Before I put you down." Kate lowered the gun. That's when the door to the Hale house began to creak open. "Allison get back."

Kristie, Scott, Allison, Chris and Kate stood at the ready, staring at the door. "What is it?" Allison asked.

"It's the Alpha." Scott said. A blur ran out of the house. It knocked down Chris, then Kristie, followed by Allison and Scott, leaving Kate standing.

"Come on!" she yelled. "Come on!" That's when Peter grabbed her. He pulled back her hand, making the gun go off twice, before grabbing her neck and throwing her onto the porch. Peter went after her, and dragged her into the house.

"No!" Allison yelled and got up. She started running towards the house.

"Allison wait!" Kristie yelled. She was about to get up, when a hand grabbed her leg. She turned, seeing Derek.

"Stay here." Derek said, before running into the house, leaving Kristie outside with an unconsious Mr. Argent. She ran over to him, making sure he was okay. Pretty soon, Allison ran out over to them, crying.

"What's wrong?" Kristie asked.

"Kate's dead."

"Allison, I'm sorry. I wish you didn't have to be involved."

"But you are. I mean, your boyfriend's a werewolf, and I'm guessing your boyfriend is to."

"Derek? Yeah. I don't know exactly what we are right now."

The sound of glass shattering made them turn. Scott rolled out of the house through the window. He was trying to get up, when Peter in full Alpha form came running out to. He grabbed Scott and growled at him, when Scott kicked him, sending him toppling backwards. He was about to go at Scott again, when headlights distracted him.

Stiles and Jackson got out of Jackson's Porsche and Stiles threw a beaker, a Molotov cocktail, at the Alpha. He caught it. Kristie looked around and spotted Mr. Argent's gun. She grabbed it and shot at the beaker, hitting it on the second shot. It exploded, engulfing the Alpha in flames. Jackson threw another and it hit, causing the fire to grow.

The Alpha roared and growled, trying to get rid of the fire. He looked at Allison and Kristie. He started towards them. "No!" Scott yelled and kicked the Alpha, causing him to fall on the ground and turn back to a burnt Peter. Peter fell on his back, the fire completely out.

Allison walked over to Scott, and knelt beside him. She kissed him, making him transform back to normal. Kristie stood and saw Derek come out of the house. "Derek!" she yelled and ran towards him, but before she could get to him, he held his hand out, stopping her.

Derek walked over to Peter and kneeled over him. "Wait!" Scott said. "You said the cure comes from the one who bit you. Derek, if you do this, I'm dead. Her father, her family...What am I supposed to do?"

"You've...Already...Decided." Peter gasped. "I can smell it on you!"

Derek lifted his hand in the air, claws extended and he slashed Peter's throat, killing him. He stood and turned to the other, his eyes flashing red. "I'm the Alpha now."

Kristie walked out of her bathroom, in sweat and a sweatshirt, toweling drying her hair. It felt good to take a shower after being stuck in an underground torture chamber. She sat on her bed and was about to turn on the television, when she spotted Derek's reflection in her mirror. She stood up, putting the towel down.

"Please don't be scared." Derek said.

"Why would I be scared?"

"Because of what you saw me do...What I am now."

"Derek, nothing you do now can scare me. It may not have been what was best for Scott, but you did what you had to do." Kristie paused. "Derek, I may be a little freaked out by this whole mate thing, but I'm willing accept it...because I love you."

Derek smiled. "I love you too." He walked over to her and gave her a passionate kiss, which she happily returned.

"Stay with me tonight." Kristie said, breaking up their kiss.

"Where else would I be?"
