A/N: I wanna say a quick thank you to the people who have commented, it really helps so thank you! I makes me so happy that you guys really like my story, so again thank you! Keep reviewing/commenting and reading! There is another note on the bottom.

"I'm sorry, did you say Slender Man?"
Peter only nodded in response to Dean's question but Dean just couldn't wrap his head around that,

"You expect us to believe that load of crap?"
"I expect you to want to save your sister, my nephew's… girlfriend, and these young teenagers beloved friend. If this 'load of crap' isn't believable, that isn't my fault and I shouldn't have to convince you. Your brother said it himself, you've come to learn that nothing is just myth."
Dean gave Sam a pointed look and Sam gave Dean a guilty one, Peter continued,
"If you really don't believe me, go ask one of your Angels."
While they continued butting heads, Stiles was on his phone looking up lore on Slender Man with Isaac leaning over his shoulder and what they found didn't ease their minds. Exchanging a look, Isaac sighed and spoke to the arguing grown men,
"He's telling the truth."
The older men turned to look at Isaac and Stiles slid his phone across the table. Sam stopped it and looked it over while Stiles told everyone else what was on there,
"Basically is just says that the symptoms that Liss has been showing all point to Slender sickness. The only things she hasn't done yet are, nose bleeds, vomit, diarrhea-"
At that Lydia scrunched up her face,
"Oh ew!"
Allison retorted,
"Be thankful its not you going through that."
Stiles continued as is he wasn't interrupted, although he did throw the two girls a glare,
"And massive paranoia, although the whole paranoia thing isn't too far away I think. Liss doesn't…cry."
He looked to her brothers' for confirmation, Sam responded to the boy,
"She isn't heartless, and you all know that. She may not cry every time she gets hurt in a fight, but that's only because she grew up with it, she's…used to it, expects it. She cries, she cried when her mother died, when our father died, when we died. But you're right about this factor Stiles, Valissa doesn't just cry, there needs to be a reason, and nightmares aren't one."
Scott chimed in then,
"Alright, so how do we kill this thing."
Peter laughed dryly,
"You can't."
Derek growled lowly and Jackson spoke up finally,
"What the hell do you mean we can't kill it?"
"Exactly that pretty boy, it can't die. It always takes a victim, it prefers the one it chooses, and unfortunately it chose Valissa."
Dean shook his head,
"There is always a way to kill monsters, this isn't any different."
A new voice spoke up,
"I am afraid to inform you, but Peter is correct. Slender Man cannot die."
Everyone turned to look at the newcomer, Castiel. Dean still didn't like that answer,
"You mean you can't just light up the S.O.B and have it disintegrate like every other abomination out there?!"
"No Dean, I cannot just 'light it up,'"
Cas used air quotes,
"It cannot die, not even by my hands."

Dean slammed his fist against the table so hard, the people sitting around it scooted back a few inches,
"Damnit Cass! That doesn't help us!"
"I'm sorry."

And with that Cas vanished. Those answers didn't sit well with anyone in the room, Sam spoke up with reassuring words,
"Well figure this out. She isn't dying anytime soon."
Erica huffed out a humorless laugh,
"How do we kill something that can't die?"
Lydia scoffed,
"You got rid of the Kamina and that couldn't die, you found a way around it and that's what we'll do now."
They all nodded and turned when Allison poised the next question,
"Alright then, how do we find a way around it?"
Stiles jumped from his chair, large smile plastered to his face,
"Well the site said that it will kill her in the forest, so for now we keep her out of the forest until we do find a way to save her. This means we all need to keep an eye on her at all times, when she's asleep we'll need to keep an even more watchful eye on her. So we'll,"
Pointing to the youngest members at this meeting,
"Watch her during school, you guys,
Pointing to her brothers',
"Will watch her at home, and when you're away on hunting trips we'll all take shifts watching her at her house. Since Derek already spends nights with Lissa he ca-"
Dean interrupted, voice laced with disbelief and anger

"What did you just say?!"
"Before you so rudely interrupted, I said that Derek already spends nights with Valissa and he ca-"
Dean interrupted once again,
"What exactly does he mean by that?"
His question was obviously meant for Derek, who pinched the bridge of his nose and sighed,
"Exactly what you think Dean. Nothing happens, you would have known, we just talk or sleep nothing more."
Before Dean could respond, Stiles continued,
"Derek will watch her at night, and on the nights when he doesn't go, one of you two will watch her and one of the wolves will stand outside the house. When she wants to go out, Allison, Lydia, and Erica will go shopping with her or to wherever she wants to go, unless she asks one of us guys. The main thing is to keep her body and mind away from the forest. I think that she now has a pull to go to the forest, so do what ever you can to distract her. For the wolves it shouldn't be that hard…"
He ended his plan with a mumble but it caught Derek's attention,
"What does that mean?"
"She is a girl…a shirtless dude will distract her, especially ones that have six packs. Not that hard to figure out, right Allison?"
Allison kept quiet but couldn't quite suppress the smile that found its way on her face, she gave him a small nod hoping Scott didn't see,
"I did see that Allison."
Erica came to her defense though,
"Oh c'mon, like a shirtless girl wouldn't distract any of you? Relationship or not, you're gonna look, its reflex. And especially if the shirtless girl was one of us, Lissa included. She's hot, even when clothed guys still look at her as if she's naked, I would know, they look at me the same way."
Allison gave the she-wolf a smile, which Erica happily returned, but Derek was scowling. Stiles clapped his hands together,
"Okay so we have a plan, everyone break!"

No one moved, and instead stared at the pale boy as if he had grown another head, Stiles groaned,
"Go home."
The Winchesters shook their heads as they got up to leave, the two girls close behind after they gave their boyfriends a kiss, Stiles got to the door and looked to Scott who shook his head and nodded towards a still scowling Derek. Stiles understood and left.

After the werewolves heard the cars leave, it was silent, they looked to each other silently asking who was going to break the tension, so the task obviously fell to Scott. Cautiously he asked their Alpha,
"What's wrong? We're going to save Lissa."
Derek growled in response, his eyes cutting to Scott who took an involuntary step back. Boyd continued for him,
"We aren't going to let anything happen to her, we all care for her."
Again Derek just growled and Erica pieced it together just as Jackson spoke,
"You are all idiots, it's not a case of worry for Lissa's safety."
Isaac asked,
"Then what is it."
"Our big, bad Alpha is jealous."
He ended with a chuckle, a glint in his eye and a smirk plastered on his face as he looked at Derek. Erica rolled her eyes,
"Pushing his buttons will do nothing for you jackass. And Derek, you have nothing to worry about. I don't even think Lissa notices how guys look at her, she seriously only has eyes for you, which I don't understand."
Isaac snorted causing Erica to pin him with a glare,
"What?!"

"You're the one who jumped on him and made out with him during training."
"He asked for the unexpected, I was only giving him what he wanted."
"I think you were far to willing to give him more then what he wanted."
Erica growled,
"Yes, I was attracted to him, every girl who looks at him is. But then he opened his big mouth, the few times he does, and that fixed the problem for me, I just don't know why it didn't work for Lissa."
Derek growled again but instead of just glaring at the poor girl he answered,
"She's my mate, that's why. She'll be attracted to me no matter my personality, which is different when I'm around her. Which is also why I'm overly protective of her and why I get jealous. We haven't fully mated yet, which means she can still leave me and not feel broken if she does because she is human…and even if we do fully mate, I will probably still act that way, her lifestyle makes it hard not to worry about the possibility of her untimely death."

Boyd perked up at Derek's answer, in fact everyone did,
"We get mates?"
"For a werewolf that's born, yes although we still have to find them and sometimes we don't. For a bitten werewolf, its rare but it is possible. Sometimes they don't even notice it, which is what I think is going on between Jackson and Lydia and Scott and Allison."
Scott's face lit up,
"Allison is my mate?"
"I'm not sure, but its possible. I mean you don't listen to me or her father when we tell you to stay away from each other."
"Why do you think Lydia is my mate?"
"She is the one who helped cure you of the curse of the Kamina, again I'm not sure it's a rare occurrence but I've heard stories."

Jackson nodded understanding his logic. Isaac sat back, folded his arms across his chest, and looked at his Alpha with newfound respect,
"So Valissa is your mate…wow. I guess I can see it."
Derek raised an eyebrow at the young Beta telling him to continue,
"Its just, you're very to yourself, quiet and quickly angered. Valissa is very much outgoing, loud, and usually a happy person unless you hurt someone she cares about or you're something she's hunting. You balance each other out, the ying to your yang, you're dark and she's light."
"Yes, mates tend to be that for each other."
Scott spoke up, far too enthusiastic for the Alpha's liking,
"How do you fully mate?"
"It's a serious matter Scott, never to be taken lightly. Its not very complicated but it is intimate. It's a stronger bond if she is a virgin, it means you're the only one to have had her and the only one that ever will. You need to have sex and when you both reach your climaxes, simultaneously which is easier to do when you're mates, you have to bite her in her neck or the area between her neck and shoulder. The thing is, it can't be forced, you both need consent to it. Obviously most male and female werewolves are more then willing to mate fully, it's the human females or males that are more cautious. The bond is unbreakable, and if one of the mated was to die, the other may not be too far behind, you literally can't live without your mate after the bond is made."

Scott nodded, his enthusiasm taken down a few notches from the serious tone in Derek's voice,
"Does she know?"
"No, but I think she figured it out, or figured it wasn't just a normal relationship."
Peter spoke from behind him,
"Uh Derek…it's a hunter dating a werewolf…nothing about that relationship will ever be normal. Especially not with your track record of hunter/werewolf relationships."
The last part Peter slightly mumbled, but Derek heard it crystal clear causing his back to stiffen and his eyes to blaze red for a moment,
"Yes Uncle, we've both realized that. Its just that with the mating, you're much more in tune with each other's emotions, you have the ability to calm them with just being near them, everything is more intense with a mate. She isn't stupid, she knows something is different with our relationship, she just doesn't know what."
"You should probably tell her, girls really don't like secrets when it comes to a romantic relationship."
"Yes Erica, I know. I just don't know how to tell her, and now with this thing and the Kamina, doesn't seem like now is the best time."
"She'll take it just fine, its better to tell her sooner then later. This won't hurt the relationship unless you keep it hidden."
With that she left, the other Betas trailing behind her, while Peter went to his room leaving Derek to think about…everything.

A/N: This chapter I'm iffy about...I realize that there are going to people who won't like what I wrote because of what the show is like but, I don't know I just thought it would be nice to put a reason behind why Derek acts the way he does around Valissa, because he acts kinda out of character...I'm sorry if its crap, but stick with me it gets better I swear.
