Selene POV: Selene leaned against the door to the broken train listening to Scott and Derek.

"I'm saying we need a new plan because next time one of us is gonna be too hurt to heal" Derek told Scott.

"I get it we can't save Jackson" Scott said sadly before giving her a weird look.

"We can't seem to kill him either" Derek replied.

"Derek slashed his throat I gutted him yet he's perfectly fine" Selene said.

"I've seen a lot of things Scott. I've never seen anything like this. Every new moon's just gonna make him stronger."

"But how do we stop him?" Scott asked.

"I don't know. I don't even know if we can" Derek said shaking his dead slowly.

"Maybe we should just let the Argents handle it" Scott suggested.

"I'm the one who turned him it's my fault" Derek said softly as he looked off into space.

"Yeah but you didn't turn him into this. I mean this happened because of something in his past right?"

"That's a legend in a book it's not that simple" Derek replied getting a little aggravated.

"What do you mean? What are you not telling me?" Scott asked also getting mad.

"Why do you think I'm always keeping something from you?"

"Because you always are keeping something from me!"

"Well maybe I do it to protect you."

"Scott that's the Alphas… a good Alphas job to protect the pack" Selene spoke up seeing Derek hurt and struggling.

"Look where that got you. Doesn't being part of a pack mean no secrets?" Scott said.

Selene felt the sting from his words and the truth. Derek closed up on him.

"Go home Scott. Sleep heal. Make sure your friends are safe. Cause the full moon's coming. And with the way things are going I've got a feeling it's gonna be a rough one."

Derek got up showing he was done talking. Scott was waiting for her a few minutes later outside.

"Selene what did you do to Stiles?"

"What do you mean is he okay?" her voice taking on a worried tone.

"He's fine but… I don't know I… smell you on him even though you two haven't been around each other for…in a while" Scott said.

Selene looked away feeling the normal pain talking or thinking of Stiles brought on.

"I…I marked him" she said softly.

"You what?"

She let out a long breath.

"I marked him… as my mate. No it won't turn him but there's a mark where his shoulder and neck meet it's a mate claiming mark."

"Why would you do that?" Scott asked angry.

Selene flashed her eyes Alpha red to show her own anger. "I love him!"

"There must have been others you loved you mark them too?"

She let her fangs and claws come out to go with her eyes.

"Watch your tone! No no others a wolf gets one mate two if the moon is kind. I've been alive centuries Scott I've only had the one" she finished softly seeing Scoot bow his head in submission to her anger.

"I'm sorry I didn't know."

"Why would you? You haven't had time to learn all there is to being a wolf. I'm sorry I let the Alpha out it's not your fault. Go home Scott and don't tell him" she turned to walk away but she still heard Scott.

"I won't… but you should."

The next day Selene and Isaac went to Derek to get the wolves ready for the full moon. Selene watched while Derek opened a box full of chains.

"What is that?" Isaac asked pointing to the mark on the lid.

"It's a triskele" Boyd answered.

"Spirals mean different things. Past present future. Mother father child" Boyd went on.

"Sun moon and twilight" Selene said.

"You know what it means to me?" Derek asked.

"Alpha Beta Omega?" Boyd guessed.

"That's right. It's a spiral. Reminds us that we can all rise to one or fall to another. Betas can become Alphas but Alphas can also fall to Betas or even Omegas" Derek explained.

"Like Scott?" Isaac asked.

"Scott's with us" Derek said.

"Really? Then where is he now?" Isaac said looking around.

"He's looking for Jackson. Don't worry he's not gonna have it easy tonight either. None of us will. There's a price you pay for this kind of power. You get the ability to heal but tonight you're gonna want to kill anything you can find" Derek said handing Isaac some chains.

"Good thing I had my period last week then" Erica spoke up.

"Well this one's for you" Derek said happily as he held up a spiked head band.

"Selene why aren't you out looking for Jackson too?" Erica asked nicely.

"I'm here to make sure you guys don't rip each other apart" Selene replied in the same tone Erica used.

Stiles POV: Stiles was sitting at his desk looking over old Beacon Hills high year books. He was trying to find the pattern for the killings. His dad stopped and leaned inside his room.

"Hey whatcha doing?"

"Homework" Stiles replied.

His did walked past only to come back.

"It's spring break. What do you think you're doing?"

"I'm just satisfying my own curiosity" Stiles said anything to help Scott and keep his mind from wandering to Selene.

His dad closed the year book.

"We brought Harris in this morning for questioning. They brought him in."

Stiles felt bad for getting his dad fired. "And?"

"And they're working on a warrant to arrest him for the murders."

"For all of them?" Stiles asked.

"Enough of them."

"With what proof?"

"You remember the couple at the trailer? Tire tracks nearby match Harris' car."

"W… that's not enough" Stiles said opening the year book again.

His dad closed it again.

"The same car was also seen outside the hospital where the pregnant wife was killed. It's got some bumper sticker on it a quote from Einstein."

"Wait what quote?"

"Something about imagination and knowledge."

"Imagination is more important than knowledge yeah. I saw the same car parked outside the rave."

"That means you're a witness. You're gonna have to give a statement."

"But what about the concert promoter Kara? She wasn't in Harris' class right? I mean what does Mr. Lahey have to do with Harris?"

"It doesn't matter. The tire tracks put Harris at the site of three murders. That's damning evidence."

"No it's not enough" Stiles said once again opening the book.

"I thought you hated this guy?"

"I don't hate him all right? He hates me. And you know if he'd killed them all then yeah lock the psycho up. But there's something missing. There's gotta be something missing" Stiles said as he looked through the yearbook.

"Hey, hey you don't have to solve this for me."

"No I have to do something. What?" Stiles asked seeing the intense look on his dads face.

"Look at the swim team."

"Dad the coach… it's Isaac's dad."

After figuring out the pattern Stiles started to get ready for Lydia's party. Once at the party it took him forever to get inside with his gift then he had to find Scott. Stiles was half hoping Selene would show up and also knowing she wouldn't it made his chest ache.

"Have you seen Jackson anywhere?" Stiles asked him.

"No. Seen Allison?" Scott asked back.

"No but we should probably tell her what we found."

"I'm still kind of not sure what we found."

"I figured out it has something to do with water. You know the fact that all the victims were on the swim team the way the kanima reacted around the pool."

"So whoever's controlling the kanima really hates the swim team?" Scott asked.

"Hated the swim team. Specifically the 2006 swim team. So it could be another teacher. Maybe like a student back then. I mean who are we missing though? What haven't we thought of?"

Then Allison showed up.

"Uh Jackson's not here" she said.

"Yeah no one's here" Stiles said.

"Maybe it's just early" Scott said weakly.

"Or maybe nobody's coming because Lydia's turned into the town whackjob" Stiles replied.

"Well we have to do something because we've completely ignored her for the past two weeks" Allison said.

"She's completely ignored us the past ten years we don't owe her a party" Scott said.

"What about the chance to get back to normal?" Allison asked.

"Normal?" Scott sounded hurt.

"She wouldn't be the town whackjob if it wasn't for us."

"I guess I could use my co-captain status to get the lacrosse team here."

"Yeah I also know some people who can get this thing going. Like really going" Stiles said pulling out his phone.

"Who?" Allison asked.

"I met them the other night. Let's just say they know how to party."

Soon the party was alive and pumping.

Selene POV: "What if we break free?" Boyd asked as Derek was chaining them up Selene watched.

"Then you'll do anything you can to get outta here. Probably try to kill me then kill each other then anything else with a heartbeat. I need you to hold her" Derek said to Isaac about Erica.

"So how come she gets to wear the headband?" Isaac asked holding Erica.

"Because she'll be able to withstand more pain than the two of you. I've got an extra one if you really want it?" Derek asked him.

"I'll pass" Isaac said wincing at the thought.

"You ready?" Derek asked Erica.

"Yeah."

He put the spiked headband on her and began screwing it on. It wasn't long before she was screaming and crying in pain with blood running down her face.

The moon was starting to rise by the time Derek got around to chaining Isaac up.
