Hey guys! Only been a week since I updated, so yay! This is a pretty good chapter, though there are much more exciting ones coming up.

Please enjoy and review!

Where there is desire

There is gonna be a flame

Where there is a flame

Someone's bound to get burned

But just because it burns

Doesn't mean you're gonna die

You've gotta get up and try

Try – P!nk

Rain beat down on the hood of the Jeep as Rayne grabbed Derek out of backseat. Scott got his other side as Stiles opened the door to the animal clinic. She stepped inside, her hair already soaked.

They quickly laid him down on the operating table, Lydia and Deaton helping them.

Deaton stared Derek's face in plain shock.

"Wow."

"Wow? Wow as in, "I've seen this before and I know exactly what to do," kind of wow? 'Cause that's the kind of wow we were hoping for." Stiles said.

"I think you might be overestimating my abilities."

"He's like ice." Rayne told Deaton, who picked up Derek's other cold hand. Rayne held his other, staring at his face. Her emotions…she couldn't tell what they were right now.

"Is it permanent?" Lydia asked.

"I'm not sure a medical diagnosis is even adequate. This is well beyond my experience." Deaton said.

"So what do we do with him?" Stiles asked.

"Until he wakes up? Probably not much. It might be best to leave him with me. He'll be safe here."

"You mean from Kate?" Scott asked.

"If she's alive and she is what you say she is, she won't be able to walk past that gate." Deaton told him.

"Why would she want do this to him?" Lydia asked.

"Knowing Kate, it's probably for a reason that won't be any good for anyone but her."

"And bad for everyone else." Stiles added.

Deaton looked at them all and his worried eyes softened a little. "You guys should probably go home. He doesn't look to be in any danger. So maybe the rest of you should get some sleep? It is a school night. And you all need to start taking care of your own lives again."

Rayne knew he was talking about their mad frenzy to find Derek, their efforts in helping Malia. It had been a long time since she'd thought of only herself.

"Someone should stay with you." Scott said.

"Me." Rayne automatically volunteered. Taking care of herself would have to wait.

"I'll stay too." Lydia said. "My grades are fine, despite missing a few classes."

"I'm so not okay with this." Stiles said to them.

Lydia pursed her lips and looked at Stiles. "Guys, go."

"No."

"Text us if anything happens." Scott said to Rayne, who nodded.

"Nope, still not okay with it. Not going anywhere." Stiles said, and Scott pulled him out the door. "All right, just 'cause you're stronger…"

Rayne pulled over a chair to Derek's side and grasped his cold hand tighter, her eyes never straying from his still face.

The sun rose, and Rayne, her eyes burning with exhaustion, looked at Deaton as he came over. Lydia was slumped over in a chair against the wall.

"Any change?" Deaton asked her.

"His body temperature is a lot better, but his heart is racing." Rayne told him, and he put his fingers on Derek's wrist, watching his watch.

"How's he doing?" Lydia asked sleepily from behind them.

"His heart rate is alarmingly high." Deaton told her, and Lydia got to her feet. She touched Derek's skin with a gentle fingertip.

"He's a lot warmer now."

"I'm going to try something." Deaton said. "Rayne, I want you to keep holding his hand if that's okay."

Rayne nodded, and Deaton retrieved a scalpel from his tray. He slid it down Derek's forearm, cutting into the skin. It sealed almost immediately.

"That looks like it healed really fast." Lydia said as Rayne stared in surprise at Derek's smooth skin.

"Unusually fast." Deaton said worriedly.

"What does that mean?" Rayne asked.

"I'm not sure. Let's try something else. Grab me a five milliliter syringe. Top drawer."

Rayne and Lydia turned and went to the top drawer. As they did, Rayne heard a hard breath, and they all turned.

Derek, his eyes glowing blue, faced them, panting through his fangs.

"Derek?" Lydia asked.

"Derek, are you alright?" Deaton asked.

"Derek, it's us." Rayne said to the panicking boy.

"Derek. Derek?" Lydia asked, and Rayne saw Derek's eyes flicking from side to side like he was about to run.

"He doesn't recognize us. Guys, we're scaring him!" Rayne told them, and Deaton and Lydia stopped speaking.

"Derek, it's okay. You were hurt. We healed you. I'm Rayne." Rayne stepped forward.

"Derek, you're going to be fine." Deaton said, taking a step forward, and Derek lashed out. Rayne pushed Deaton out of the way as Derek's claws shot for them. She winced as they dug into her arm, carving out bloody furrows. The force of the blow knocked her back, into the cabinets. Deaton and Lydia crowded around her, but the wound was already healing.

The clinic doors swung open and closed from where Derek had just disappeared.

Just a half-hour later, Scott and Stiles finally reached the clinic, looking immensely worried from whatever Lydia had said on the phone.

"Are you all right?" Stiles asked Rayne, who smiled wanly.

"It's already healed. I'm more worried about Derek to be honest." Rayne looked at Deaton.

"I don't think he's just younger in body. I think he's younger in his mind too." Deaton told them.

"He didn't recognize any of us. And he looked like he was scared out of his mind." Lydia told them.

"He has a reason. His eyes were blue. Which means he's from some time after Paige, but before the Hale fire." Rayne said.

"So if you're a teenage werewolf and you're scared, where do you go?" Stiles asked.

"A wolf goes back to its den. But Derek lives in a loft." Scott said.

"Not when he was a teenager."

"The Hale House." Lydia said.

"He wouldn't remember the fire. It wouldn't have happened yet." Deaton said.

"Hold on. Say you do manage to catch up to him? What are you going to say to him? That his whole family is dead?" Lydia asked them.

"I guess I'm going to have to." Scott said.

"Oh, good luck with that." Lydia told him sarcastically.

"She's probably right. Maybe you shouldn't. You know, at least until we figure out how to get him back to normal." Stiles said.

"I can't lie to him." Scott said.

"Okay, Rayne can do it." Stiles said.

"I'm not lying to him about his dead family." Rayne said vehemently.

"I don't think any of us can lie to him. Remember, he can hear a heartbeat rising. When we find him, we tell him the truth." Scott said.

Deaton sighed. "If he gets to the house first, you won't have to."

Scott, Stiles, and Rayne climbed into the Jeep and took off. Rayne kept fiddling with things; braiding her hair, tying and untying her shoes, twisting her hands around each other.

"We'll fix him, Rayne." Scott said, and Rayne scoffed.

"Yeah, because we totally know what to do in this situation." She said sarcastically.

"Everything always works out." Scott continued optimistically.

"Not everything." Stiles said.

Stiles's police scanner buzzed to life, and Rayne listened intently as Deputy Parrish's voice came over.

"We've arrested a delinquent at the Hale House, Sheriff. He tried to attack Haigh." He said.

"Bring him in." Sheriff Stilinski said.

Stiles swerved around a corner and they took off for the sheriff's station.

They rushed in to find Sheriff Stilinski staring at Derek with a perplexed expression on his face. He spun to look at them and sighed.

"I'll handle this." He said to Parrish, and waved them into his office.

Rayne could tell he was not pleased as he stared at them from across his desk.

"I want you to be honest with me. Absolutely and completely honest." He said seriously. "Have you been time traveling?"

"Hang on, what?" Stiles asked.

"Because if time traveling is real, you know what? I'm done. I'm out. You're going to be driving me to Eichen House."

"We found him like that." Scott said quickly.

"Where? Swimming in the fountain of youth!"

"No. We found him buried in a tomb of wolfsbane in an Aztec temple in Mexico underneath a church in the middle of a town that was destroyed by an earthquake." Stiles said, and Scott and Rayne both sighed.

"You told me you were camping!" Stilinski said to him angrily.

"Yeah, we were." Stiles said. "In Mexico."

"Look, Derek's been aged back in time. We don't know how." Rayne explained. "But he doesn't remember anything."

"We just need to talk to him." Scott said.

"Yeah, well, so far he's not talking to anybody." Sheriff Stilinski said with a heavy sigh.

"He'll talk to me." Scott said confidently.

"Why would I go anywhere with you?" Derek asked Scott as Stiles and Rayne watched.

"There was an accident. You lost some memory, but we can help you get it back." Scott told him.

"How much memory?"

"A lot. But you can trust us."

Rayne saw Scott's eyes glow, and she flashed hers at Derek so he could see. His eyes widened.

"You're an Alpha." He said. "And you're his beta? Okay, who are you? And who is he? Who are you?"

"Oh, we're the guys keeping you out of jail." Stiles said.

"Let us help you." Scott said.

"No!"

"Okay, dude, you almost tore apart two cops back there. You need to listen to us. And that starts with no fangs, no claws, no wolf man. You got that?" Stiles asked.

"I'm fine as long as it's not on a full moon." Derek said, and Rayne looked at Scott, puzzled.

"You still have trouble with the full moon?" Scott asked.

"I said I'm fine." Derek snapped.

"All right, you coming with us or not?" Stiles asked.

"You want me to trust you?" Derek asked. "Where's my family?"

Scott looked at Rayne, who nodded. "There was a fire. And…they're not here anymore." Rayne looked at Scott sharply as he continued. "They're fine. Just had to move out of Beacon Hills. And we're going to take you to them as soon as we figure out how to get your memories back."

Derek's eyes looked vaguely wet as he nodded. "Okay."

As they watched him get released, Scott sighed.

"I shouldn't have done that. I lied my ass off." He said.

"Hey, your ass is fine. You saved him a ton of unnecessary pain. We'll figure this out in a day or two, he goes back to being old Derek, everyone's happy. Except for Derek, who's never happy." Stiles said.

"It's just another person that we're lying to. I always feel like it's always been better when we tell the truth. With Lydia, my mom, your dad." Scott said.

"Yeah, but that is Derek Hale in there. He may be a kid right now, but he's still Derek Hale." Stiles said.

"I don't know. We're lying to Malia, now we're lying to Derek. I don't like it." Rayne said.

"All right. Take him to my house and don't let him out of your sight." Scott told Stiles.

"And where are you two going?" Stiles asked.

"We're going to go talk to the guy we should have gone to before." Scott said as he and Rayne walked away.

"Uh…yeah, I hate that guy!" Stiles called after them.

"So do I, Stiles." Rayne answered, then repeated in an undertone. "So do I."

"Uh-oh." Rayne murmured in Scott's ear as they pulled up in front of the loft.

"What are you doing here?" Scott asked Malia as he took off his helmet.

"I heard you were coming to talk to Peter. And since Lydia tells me he's basically Satan in a V-neck, I figured you two shouldn't be alone." Malia said.

"We can handle Peter." Scott told her.

"You can handle him better with me." Malia turned and walked away, and Rayne swapped an anxious look with Scott before following.

"What's wrong with you two?" Malia asked as they walked through the door.

"Nothing." Scott said.

"Your heart's pounding like crazy. Are you nervous?"

"They're just bad at introductions." Peter said from the couch where he lay.

Scott took a deep breath. "Peter, this is Malia."

Peter set down his book slowly and stood, staring at Malia's face. Rayne felt the urge to step in front of the girl.

"Beautiful eyes. Did you get them from your father?" Peter asked her.

"Mother." Malia asked, leaning backward.

"Interesting. Anyway, I'm sure they've told you a lot about me." Peter moved away, and Rayne relaxed.

"The homicidal killing spree came up." Malia said.

"Well, we're all works in progress."

"Well, when you progress to your next killing spree, why don't you try and make sure they all stay dead?"

"What is that supposed to mean?" Peter said, moving back towards the couch.

"What do you know about people being turned by a scratch?" Scott asked.

"Did you scratch someone, Scott? Don't worry about it, the claws have to go pretty deep." Peter said.

"But let's say if you, in the midst of rage, clawed out someone's throat-" Rayne said.

"Well, yeah, it's possible. It's also beyond rare. We're talking one in a…" Peter's eyes grew dark, and he growled the last word, "million."

"Can't someone in this town stay dead?" He exclaimed angrily, whirling around.

"I think they were hoping you would." Malia said.

"Do you have any idea why Kate would turn Derek into a teenager again?" Scott asked.

"What color were his eyes?"

"Blue. After Paige's death." Rayne said.

"Which could mean around the time he first met Kate." Peter said.

"Wait, what?" Rayne asked, her stomach suddenly in her chest.

"Derek and Kate knew each other?" Scott asked.

"Biblically." Peter turned back around and smirked at Rayne's paling face. "That's right, Scott. You weren't the first wolf to climb into a hunter's bed."

Rayne instantly felt sick to her stomach, dizzy even. How could…the Derek she knew would never…

But then again, she didn't know this Derek. And Kate did, all too well.

"Okay, Derek went to the site of the house thinking it was still there, right?" Peter asked.

"Yeah. But he doesn't remember the fire." Scott told him.

"But if he doesn't remember the fire, then he doesn't remember that it was Kate that set it." Peter said.

"And?" Rayne said. Her voice held strong despite the feeling that the ground was rolling up and down beneath her.

"Kate didn't just take him back to being a teenager. She took him back to the age where he still knew her. When he still trusted her."

Rayne pulled out her phone and called Stiles right away. He picked up after the second ring.

"Hey, Stiles, where's Derek? We think Kate might be after him." She said.

"No, he's in Scott's bedroom, he'll be totally fine." Stiles told her. "To be honest, I'm starting to miss the old Derek."

"That's a relief. Listen, Kate can use him. He's at the age when he knew her and trusted her, and she can use that. So you need to keep him safe." Rayne told him.

"So, if you actually think that Kate's coming to find him…" There was a long pause.

"Stiles?" Rayne asked.

"You might be right." Stiles said, and Rayne hung up.

"Kate's got him. We need to move." She told them, and they rushed for the door.

"Wait." Scott said suddenly.

"For what? Kate's out there twisting her way into Derek's head yet again." Peter said.

"We need to find her." Scott said.

"All we need's a scent." Malia said.

"That could take hours." Scott said. "If we want to get ahead of her, we need to figure out where she's going."

"Not to underestimate my own cognitive faculties, but we're not exactly a brain trust of geniuses here." Peter said.

"But we know one." Rayne said.

Scott called Lydia, and instantly his face grew worried.

"Lydia and Kira found a dead body. Ripped to shreds, apparently."

Peter looked at Rayne.

"Kate." She said.

"Kate." He agreed.

"We called Stilinski. They're on their way." Lydia said as Scott put her on speakerphone.

"What does it look like? Can you send pictures?" Scott asked.

"Uh, okay." Lydia said. "To be honest, I have a 4.0 in AP Biology and there are parts of the human anatomy I have never seen before on these walls."

Rayne heard some disgusted gasps and squelching and suppressed a shudder.

A picture popped up on Scott's phone, and Rayne looked at the ravaged man with disgust.

"Why would she want to kill a gas station attendant?" Malia asked.

"I don't think she could help it. This was done in a frenzy. It's not a murder. It's a symptom." Peter said.

"Of what?" Scott asked.

"She can't control the shift." Peter said.

"Derek said he had the same issue on the full moon. That he was still learning." Scott told him.

"Kate's still learning?" Malia asked.

"Yeah, and she wants to learn." Rayne said.

"So she wants Derek to teach her?" Scott asked.

"No." Peter said. "She wants the Triskelion."

They sprinted to the school on foot, Peter leading them up the steps to the front of the school. Suddenly, a foul scent hit Rayne's nose, and she paused, along with Malia.

"Did you catch a scent?" Scott asked them.

"The same one." Rayne said.

"The same one as Mexico." Malia added.

"What are they talking about?" Peter asked.

"One of them came after us in the Church ruins. And one on the road." Scott told him.

"They couldn't have followed us here." Malia said.

"But they could've been brought, by Kate." Scott said.

There was a low, ominous growl, and Peter's face grew slack.

"Oh, I've heard that sound before." He said. "Did it have an animal skull? A human wearing a skull over its face?"

"Oh, no, don't tell me-" Rayne said.

"What are they?" Scott asked them, and Peter looked over Rayne's head. She turned.

"Berserkers." She said.

A creature stared at them, a tall, muscular man covered in bones, a skull over his head, a bone dagger in each hand.

Malia began running at the thing, but Peter grabbed her.

"Are you crazy?" He asked her incredulously.

"There's just one of them." Malia said.

"And that means we have a chance." Peter told her.

"To beat him?"

"To survive."

Peter took off running, and Rayne looked at Malia and Scott.

"As much as I hate to say it, he's right. We need to run." She said, and they took off up the steps. Rayne heard dry bones clattering behind her and pumped her legs faster.

They kept running, through the school, Malia in the lead. Suddenly, she came to an abrupt halt, and Rayne could see why.

A Berserker blocked their path, growling.

They backed away, and the second one emerged from behind a column.

"Scott. It's both of them. They're both here." Malia said.

"Where the hell's Peter?" Scott asked.

"He's gone." Rayne said, and they sprinted up the stairs, the Berserkers following.

One leapt down in front of them, cutting them off, and Rayne gripped the railing hard.

Scott roared as he leaped up, jumping high over the head of the Berserker, using one of the many pillars to leap off of.

He began fighting it, and Rayne, with a growl of fury, leapt for the second, followed by Malia. They began their attack, but the Berserker threw them off like flies. Malia let out a cry of pain as a bone dagger plunged into her leg. Rayne helped her climb the last few stairs and put her back against the wall. She stood in front of her protectively as Scott came sliding back to them. Rayne pulled him back and stood up. She faced the Berserkers as they advanced, growling at her. She knew she'd be torn apart, but she had no choice but to defend her friends.

Suddenly, there was a flash of movement, and Kira leapt in front of Rayne, wielding her katana. She attacked the Berserkers in a flurry of movement, and for a split second, Rayne thought she might fight them off.

Then she glanced back at Scott with a grin, and Scott screamed, "Kira!"

The Berserker whacked her across the face. She flew back and slid across the floor to rest besides Scott, who grabbed her arm.

Rayne turned back to face the Berserkers, who kept advancing. And then…behind them, there was a familiar figure.

Rayne leapt for the Berserkers as Derek did, engaging them, working as a smooth team as they always had. Age made no difference to that.

Derek grabbed Rayne and whirled her around. She kicked out at the Berserker, slamming it into the locker. They ducked and weaved around the clumsy animals, no longer horribly threatening. They weren't winning, but they were surviving.

Rayne caught a glimpse of Derek's face and saw the one she knew before it changed back.

"Come on, Derek, fight it!" She cried over the sounds of the melee. "Fight her!"

There was a long, low howl, and the Berserkers turned and ran. Derek watched them go, and Rayne looked at his back from where she stood right behind him.

"Derek?" She asked, and he turned. It was the old Derek, and she smiled happily to see him look at her and recognize her. But his eyes…

Instead of the familiar blue, they glowed bright yellow.
