You stood in gym class as you see Scott and Allison climb up the Rock wall. Stiles had his arm around you

"I'm glad your okay."

You smiled at him, Stiles looked at you, he pulled you close and kissed the side of your head.

"I'd be lost if I'd lose you or Scott...or anyone I care deeply about."

That's when you see Scott fall, coach goes to him

"McCall, I don't know why, but your pain gives me a special kind of joy... Right?" Laughed coach

Scott got up,

"All right, next two! Stilinski, Erica, let's go! The wall."

Stiles got ready as Érica was lagging a bit

"Oh, please--"

You went to her,

"It's alright you've got this."

Erica tried climbing up, and Stiles climbed fast and went back down. Erica started to feel a bit dizzy

"Erica? Dizzy? Is it vertigo?"

"Vertigo's a dysfunction of the vestibular system of the inner ear. She's just freaking out."

Erica started to cry, you nudged Lydia and she shrugged

" Erica..."

" I'm fine."

"Coach, maybe it's not safe. You know, she's epileptic." You said

"Why doesn't anybody tell me this stuff???"

Coach then goes back to Erica

"Erica, y-you're fine. Just-just kick off from the wall. Th-there's a mat to catch you. Come on."

Erica then went down and you tried to Console her

"See? You're fine. You're on the ground. You're all right. Let's go. Shake it off. You're fine."

"Hey Erica is fine. Don't worry"

"Listen up! Anybody sees Isaac Lahey, you immediately tell the principal. Get a teacher, or you call me. Except for you, Greenberg-- don't call me for anything. I'm not kidding. Don't call me. You shouldn't even have my number."

You went towards Scott and Stiles

"Isaac?" Said Scott

"It's Derek's problem now..." answered Stiles

You sighed

"Touchy subject i know."

"Everyone GET CHANGED !" Yelled coach

"I'll see you guys."

After a couple minutes you came out the shower,

"Your so blood taking a shower in the girls locker room."

"If guys can do it I can too."

Lydia rolled her eyes

"You just love showing your perfect body."

You smirked

"My curves is what makes me good."

"Are we still on for tonight?"

"I feel like I'll be a fifth wheel." You said

That's when you felt something off

"Somethings wrong !"

You quickly rushed out, that's when you see Erica fall and Scott caught her. You all rushed to her side

"How'd you know ?" You asked

"Place her on her side." Said Allison

"I don't know... it was just a feeling."

*timeskip*

It was lunch time at School, you smelled a certain scent and went outside, to see Derek outside his car as if he was waiting for someone

"What are you doing here ?" You asked

The door open and you see Erica, Scott and Stiles following behind

"Erica ?"

"He's here for me."

You looked at her then at Derek

"What?"

"I know he's your ex and all but he's hot and he's on the market. Plus he can have someone better than a prude."

You crossed your arms and irked a brow

"Excuse me ? "

Stiles and Scott noticed this

"Hey guys let's take it easy."

You raised your hand

"You heard me... maybe that's why he left you... cause you couldn't give it up"

You knew Derek was listening

"Erica get in the car."

"I'm a better you y/n.... Trust me."

"I was nothing but nice to you!"

"That was you pitying me. I didn't need it nor want it. You think your such a good person but in reality your not-"

"ERICA."

She just smirked

"Are you going to cry ? Awww Derek look your pathetic ex is crying... she's still inlove with you."

You closed your fist and slightly held it behind yourself. Stiles and Scott noticed this, and also noticed blood drip down your hand, that's when Erica was grabbed by the arm

"Get in the car." Said Derek

He held a smile but it soon faded when Scott and Stiles got closer to you. That's when he drove off.

*timeskip*

You waited outside the ice Rink with Allison and Lydia, soon Stiles opened it and you five went inside.

"I definitely feel like a fifth wheel."

You were tying your lace for the skates. Once done you got onto the ice. You started skating around that's when Scott was having trouble as Allison was helping him Lydia and Stiles were skating together. Seeing them four together made you realize that it sucked being lonely. As you tried to leave you fell,

"Are you alright ?"

You hear stiles ask, you looked at them

"I-I'm fine."

You sat and took off your skates and walked the rest of the way. You tossed them aside and went towards a vendí machine. You grabbed a chocolate bar and a bag of chips. Just replaying the moments of earlier today got you upset. You tightened your fist and hit the glass causing it to shatter. You then heard Lydia screaming you quickly rushed to see Stiles with her... you Looked at Scott and Allison as they looked concern as well.

*next day*

You set your tray down next to Stiles

"Hey you guys.... Oh my god Scott you got the pudding ? What - there was some ?"

"Your in cheer again?"

"Uh I have to show my support. I've been demoted to Co Captain."

"Isn't that Good ?"

"Not when my team of freshman are slacking... and my partner is horrible teacher... how does coaching go with Jackson?"

Scott stood silent, all he did was slide his cup of pudding.

"Thank you. Here, I know it's your favorite"

You slide him a bag of lays which he liked

"Oh great!"

""Y/n, Scott, do you see that?"

"What? It's an empty table?"

"Yeah, but whose empty table?"

"..Boyd." You said

You three got up and packed your things and threw away your lunches.

"I'm going to the ice rink, see if he's there. And, if he's not at home, you call me, got it? What?"

" Maybe we should let him..." said Stiles

"Boyd, you know, ma? You said Derek's giving them a choice, right?"

"We can't."

"You gotta admit, Erica looks pretty good... You know, the word "sensational" comes to mind..."

You hit his arm and he winced

"Yeah, how good do you think she's gonna look with a wolfsbane bullet in her head?"

"It'll be good... the next time the butch wants to talk shit to me like that I'll rip her throat out."

Stiles and Scott looked at you, you shrugged and looked at them with a smile

"All right. That's completely psychotic.... But All I'm saying is, maybe this one isn't totally your responsibility." Said Stiles

"They all are. And you know this thing's gonna get out of control. That makes me responsible."

"All right, I'm with you. And, I also gotta say... this new-found heroism is making me very attracted to you..."

You laughed

"Shut up."

" No, seriously! Do you wanna just try making out for a sec? Just to see how it feels"

Scott pushed Stiles

"I'll meet you at the Rink do whatever you gotta do. I have to see my aunt."

"Great.. see ya."

*time skip*

You were at home, as your aunt was cooking

"So...."

"So?"

"I wanna talk about what happened two nights ago."

You sighed

"No."

"You basically broke your door after slamming it shut."

"Okay..."

"What happened?"

"Derek happened ! He starts playing with my feelings."

"Honey Derek has been through a lot...."

You stood up

"Whatever... stiles is calling me"

Y:hello?

S:Érica just hit me with my own part of my car!

Y:what!?

You walked out the house and started to walk

S: Im sure she's at the ice rink...

Y: I'm going there !

*timeskip*

You open the door and you already could smell the scent of Derek, and Scott, along with three others. You see Derek and Boyd walk away from Scott in the floor

"ERICA !!!!!!" You yelled

"Oh look here ! Scott your bestfriend-"

You punched her, she fell back issac growled at you, Erica looked at you as she was bleeding from her nose

"You stupid bitch! Ever come at Stiles like that again I will seriously kill you!"

"Oh please I can kill you easily. I'm stronger than you."

"Y/n walk away..."

Derek stood infront of you

"Move Derek..."

"Y/n- let's go."

"No... I'm sick of this shit! Isaac the reason I liked you was because treated me as if I mattered but now your a asshole... and Erica you were a great person but your just another slut."

You went towards Scott and helped him up...

"Let's go home-"

That's when you were tackled, Erica was in top of you, but you kicked her off, you get back up

"Control your Dog Derek..."

"You bitch."

Erica blood had fallen on your face... Scott went to you

"Let's go."

"Erica calm down.@

You and Scott were walking away

"That's right ! Run your coward ! Just like your mother !!! Oh that's right she's dead... she took an easy way out by killing herself."

You stopped

"Y/n... calm down..."

Your fangs came out as your eyes changed. Suddenly you were holding Erica by the throat against the ice cleaner machine. Nails deep into her throat, everyone was shocked at how fast you were

"Never talk about my mother again!!"

You sank your fangs into her neck and drank her blood... she was choking and she fell unconscious. You tossed her body to the side and wiped the blood from your lip... you looked at the four of them, you smiled. You walked passed Derek, Issac and Boyd

"What are you?" Asked Issac

"Someone who will personally kill you if you ever step Out of line. So be cautious..."

You returned to normal and sent a wink to Derek

"Let's go.."

You and Scott walked away and Issac went towards Erica

"You just let her do that to Erica ?" Asked Issac

"I told you and her to leave her alone... Erica had it coming... none of you are to lay a finger on her. Or even talk to her in a threatening way."

"Is it because she's your Ex?" Asked Boyd

"It's complicated."
