Disclaimer: I don't own teen wolf

Throughout the movie, Derek knew there was another werewolf with them in the theater. He had to relax his muscles so he won't alarm stiles, who were really enjoying the movie.

He can sense the yellow eyes on them almost every five seconds. He just wanted to go over and throw him through a wall to knock some sense into the werewolf for not controlling himself.

He turned his head to the lower right side of the movie theater and met yellow eyes. He quickly flashed his red eyes at the other, who quickly faced forward and pretend he's watching the movie.

Derek looked around the theater when he heard a low growl. He turned to stiles when he heard it coming from stiles. The teen tensed beside him. He was shocked that stiles' eyes were red, just like an alpha's.

"Whoa, everything is so…clear" said stiles in awe

Derek didn't say anything. He just started at the red eyed teen. He didn't know what to say because he never heard of this before. Stiles' red eyes only lasted for about half-a-minute until they returned to their regular color. He didn't move for a while. Stiles noticed something was wrong when the arm around his shoulders tighten without its owner noticing.

Then the teen caught a scent in the theater. He sniffed the air. He caught another werewolf's scent once he got passed the popcorn and other theater food. Another growl erupted from hi on its own. He saw the werewolf stiffen and could smell the fear that was coming from him.

Derek recovered and tightens his arm around stiles again so stiles won't do anything rash. His thought raced to think back if he bit stiles. The only one he can think of is when he bit stiles but that was the claiming bite.

The movie was about to finish when Stiles calmed down a bit. He was confused on why the teen was acting like this. When the movie ended, stiles grabbed Derek's hand and quickly walked out the room before anyone can get up and out the building.

As they walked a bit, stiles turned to Derek and asked, "What was that?"

"I don't know," replied Derek, "I never heard of this happening before"

Stiles growled again and Derek looked around to make sure that no one was around to hear stiles.

"Come out" said stiles

Derek then sensed the werewolf that was inside the theater room with them. The said werewolf slowly came out from between two cars with his hands up.

"Who are you and what are you doing here?" said the teen with red eyes

The werewolf told them that he wasn't there to fight them. That he wanted to help them against Ana. He told them that he's a beta in her pack but told them that Ana is going insane with her obsession with Derek.

"So what do you want us to do?" asked Derek

"Kill her or…I don't know but you have to help us" asked the beta, "if this keeps up, we'll be killed"

"Why should we help you?" blurted stiles

"She'll be dead and leave you alone for good maybe? Some of us want the head beta to lead us and be the new alpha but he's in chains because of Ana"

Stiles and Derek looked at each other. Stiles knew that the alpha was growing tired and irritated of Ana's attempts to kill him.

Derek wanted to get rid of her as soon as he can. Now that he and stiles are mated, his protective instinct is at its highest because they mated just recently.

"stay." Said Derek to the beta in his alpha voice

He pulls out his phone and dials Ian's number. He tells Ian what Ana's beta just told them. He also told the other alpha where they are.

Ian made it to the place they're at as fast as he can with two of his betas with him. Ana's beta told him everything he told to the beacon hills alpha. He told them that they don't want Ana to lead them anymore and how she's going insane.

"She's insane. She keeps saying that Derek is her mate and that the human is in her way from what she wants"

"Where is she hiding?" asked Ian

"We're at another warehouse at the moment. But I don't know how long where going to stay there"

"Which warehouse?" asked Ian.

The werewolf gave them the address and where to get in so they can surprise and corner Ana.

Ana's beta left so he can get back as fast as he can so Ana won't get suspicions. Ian and Derek exchanged a few words about their next plan. They both agreed that they will get together and form one later. Stiles and the tow other betas waited for their alphas to finished.

When the alphas departed, stiles was at Derek's side in seconds and both started to head towards the Camaro. Ian and his betas were heading towards their car.

"Are you both going?" asked stiles

Derek nodded, "we have too. She's getting to dangerous"

In the Camaro, Derek knew that stiles was nervous. The teen wouldn't stop fiddling with the werewolf's fingers that he had in his lad. When they made it to stiles' house, they noticed that the drive way was empty so john wasn't home.

Stiles walked up to the door and unlocked it and stepped in with Derek following close by. They went up stairs. In his room he changed into his pajamas and started to fall asleep when he hit the bed. Derek joined him after taking his jacket and shirt off leaving him in his pants.

When the werewolf climbed in, stiles moved to his side and started to cuddle up to him.

"Derek, when you bite me…was it 'the bite'?" asked a very sleepy stiles

"No, it was a mating bite. It's so any other werewolves know that I claimed you" replied Derek in a whisper

"Then why did I growl?"

"I don't know," said Derek, "we need to talk to Deaton tomorrow"

"Yeah, tomorrow" said stiles and his heavy eyelids finally closed.

As stiles breath evened out signaling that he was asleep, Derek was still awake. He nuzzled into stiles neck and breathed in the teens scent. He got his phone out and started to type a text peter, Isaac and Scott. He told them on what happened at the movies and that they are going to meet up with Ian to attack Ana.

After putting away his phone, he let his eyes close.

"Scott, what are we here?" asked Lydia, "its late and cold out. If I get sick tonight, you won't want to know what happens"

Scott rolled his eyes, 'were here because you have to help me" answered Scott

"Help with what?"

"Help me track down the pack that's after stiles" said the tan teen

"Can't you just text Derek and ask him if he has any information?" said Lydia and she tried not to trip on the things that are on the floor in the train depot, "and what makes you think that I can help?"

"My phone's battery died," said Scott, "and I don't know, you sometimes have your moments with supernatural stuff"

"Sometimes have my moments?" asked Lydia, "what does that mean?"

"You know, like when the thing with Jackson. You stopped him with just a single key. Also the time when you were at the hospital and walked out and disappeared for days" said Scott, Lydia was about to respond but Scott cut her off, "and when you brought peter back to-"

Lydia sighed loudly cutting Scott off from his ranting, "Fine, what do I have to do?"

"I don't know. I thought you knew how to do those types of things."

"If you wanted to track them, shouldn't you have asked Isaac or Derek?"

"I don't really see Isaac that much out of school. He's usually hiding inside where ever Derek is staying at" answered Scott

Lydia sighed in irritation, "Can't you sniff them put yourself?"

"Just c'mon" said Scott

Both teens then started to search through the train depot. Ana's pack didn't really clean after themselves when they left. The entire place was filled with trash so it was hard to look for something.

"What are we looking for again?" asked Lydia

"Something that will lead us to where they are at" said Scott

"Like a map maybe?"

"Yeah…yeah, I guess that can work"

"Alright then, here" said Lydia as she thruster a wrinkled paper to his chest

Scott grabbed the ball of paper and started to flatten it out to have a better look at it, "They're not very smart are they?"

"You're not the smartest color in the rainbow either Scott" said Lydia

Scott then makes a face that says he's obviously offended. He then brushed it off and looked at the map in his hands. There was a spot on the map that is circled and arrow pointing at it.

"c'mon let's go," said Scott, "it's getting late"

The front door opening and closing woke the werewolf from his slumber. He lifted his head and looked at the clock that said 2:33 am. Derek quickly unwrapped himself from stiles without waking him. He gathered his jacket and shirt and went out the open window. The werewolf can hear john Stilinski footstep's in the hallway and as he opened the door to check on his son.

When the door closed again, Derek waited for a few minutes. He waited as he heard the sheriff go down stairs to the kitchen and then upstairs again to his room. The alpha werewolf then went back inside when it was safe to enter when john fell asleep.

Derek slipped back inside and was about to wrap his arms around stiles torso until a scent hit his nose and his eyes flashed red. The scent disgusted him, it was pure lust. He got up again and without bothering to up in his shirt he jumped out the window.

When he landed his eyes immediately landed on Ana –who eyed his muscular chest and torso-

The female werewolf was standing in front of the Stilinski household and had a smirk on her face. The scent of lust was coming in waves and Derek wished that he doesn't have his sense of smell.

"What are you doing here?" Derek scowled at Ana

Ana smiled at the muscular alpha," I'm here you see you obviously"

Derek growled, "Leave. Now"

"That's not a nice thing to say to a lady," said Ana, "also, we're going to be future mates after all"

"I already have a mate and I don't need you" Derek's eyes flashed red

"I guess we have to fix that then" said Ana as her eyes flashed red and looked up and stiles window

Derek got in a defensive stance ready for Ana if she attacks, "I said leave now"

Ana smirked at the other alpha, she didn't make a move towards him or at the house that held two humans. One which 'stole' Derek from her, She started to make another plan in her head but had to think it through. She didn't want anymore of her betas killed so she started to back away until she was out of eye sight.

Derek stayed outside foe a few minutes; He wanted to make sure that Ana was far away from the house until he went back inside.

After he was certain that she was gone, he climbed back through the window and quickly went under the covers with stiles. The teen was still asleep. Derek wrapped his arms around stiles and was wake for awhile. Ana's visit was keeping him in high alert but soon his eyes stayed to drop and fell asleep.

Derek woke to the sound of something hitting the water of the toilet in the bathroom. His nose wrinkled when the smell of vomit reached him. The smell was similar to Ana's arousal smell.

He heard stiles in the bathroom brushing his teeth two times. Derek was concerned about stiles when he walked into the room because he was walking slowly and with a hand on his stomach. When stiles was in arms reach, Derek circled and arm around his waist and slowly pulled him back into bed.

"I'm so glad it's a Saturday today" muttered stiles

"What's wrong?" asked Derek

Stiles shrugged his shoulders, "I just felt sick when I woke up"

Stiles moved closer to Derek. They both stayed like that until Derek heard john's door open. He moved off the bed and quickly went under to hide with difficulty

Right when Derek pulled in one of his legs john opened the door and walked in.

"I heard that you were vomiting, you ok?" he asked

"Hey dad, no need to worry; I think I just ate something bad that's it" said stiles with a grin

John nodded his head buying the story, "ok then, you don't look so good"

"I'm just tired. I was up last night studying for a test next week" said stiles

"Ok" said the elder Stilinski and he closed the door and he headed back to his room.

Stiles huffed and fell back onto his bed which was really hard because a certain alpha was under it.

Hey everyone, sorry that I kept you guys waiting. I tried to update but I just postponing it and being really lazy. I didn't plan on keeping you guys waiting this long.
