"STILES! Oh my god! You scared the crap out of me!" Eric gasps as Stiles appears in front of her in the middle of the forest as if from nowhere. Stiles grins keeping his fangs in check as Erica tries to slow her heart, obviously freaked out by Derek's howl and not hearing the clumsy human's approach.

"Sorry, didn't mean to startle you." he apologizes, doe eyes soft and disarming. Erica smiles in response flicking her long blond hair over her shoulder, trying to settle back into her 'tough girl' act.

"So, do you know why Mr. Alpha's howling at the moon?"

Stiles shrugs rocking back on the heels of his sneakers.

"Could be anything, you know Derek, always over reacting."

Erica nods slightly before her face falls, her big brown eyes trailing down Stiles' new, improved body.

"Hey, you okay Stilinski? You look... different?"

"Good though, right?"

The gulp Erica takes warms him from the inside out as he takes a tiny step forward.

Unconsciously, Erica steps back.

"I look better right? I'm pretty sure I'm taller too. Do I look taller to you?"

Another tiny step forward.

Erica's back hits the tree with a jolt. Not used to feeling trapped, not used to feeling like prey.

Stiles' grin slips into a smirk changing his entire face and Erica has a hard time trying to make him look like the sweet boy she used to have a crush on in 9th grade.

"Stiles? What's happened? You're freaking me out okay, this isn't funny."

Stiles takes another step towards Erica, pressing his entire body flush against hers, his long elegant fingers find a stray piece of her golden hair and curl it around the digit, locking their eyes together.

"Don't you think I look better Erica? Don't I em feel /em better to you? Isn't this what you used to want huh? Or is it Derek you want now? emNo? /em What about Scott? Or Boyd huh? Maybe it's Isaac, he sure is handsome, although I'm pretty sure he doesn't swing your way any more." Stiles pauses thoughtfully, abandoning playing with Erica's hair to stroke across her cheek.

She's frozen, paralysed by the power flooding through Stiles' veins and into her skin. Her pupils slightly dilated, the gold of her wolf shining in her eyes.

Stiles leans in closer, dragging his noise down the side of her neck breathing in the scent of strawberries and forest and that underlining scent of werewolf.

"What is it you want? Me? Or am I not your type any more? Do I need to tilt my head back and howl at the moon? Sprout weird facial hair and lick my own balls?" A dark chuckle bubbles out of Stiles' mouth spreading goosebumps across Erica's porcelain skin.

Stiles takes a big step back breaking his hold on Erica sending her to her knees; confused, hurt, scared.

"What... What's happened to you? I don't like this Stiles! Please stop it you're scaring me!"

Stiles smirks, glancing down to where his hands are curled into fists making the muscles in his arms bulge. He takes a deep breath, relishing in the delicious smell of Erica's fear, and lets out his fangs, lets his eyes bleed red, the veins around them protruding and pulsing under his ivory skin before slowly lifting his head.

Erica's scream never makes it out of her throat.

"Am I monster enough for you yet!?"

"STILES STOP!"

Stiles' eyes flicker back to their normal honey brown.

"Derek?" he whispers, spinning around to see Derek, Scott and Isaac at the edge of the clearing.

The strength literally drains out of his body, the switch in the back of his brain suddenly flicking on without his consent.

"Derek, help me." he manages to choke out, broken, before collapsing to the forest floor in a crumpled heap.
