Teen wolf imagines and preferences

Derek- something unpredictable

She had never liked Erica, the shewolf that strutted around like she owned Derek. It wasn't that Y/n and Derek were together but she loved him. They had been friends for years, Derek's mother had turned her two months before the fire, and they had both looked after each other when it happened.  Stiles always encouraged her to tell him, especially when he realised that Derek wasn't a mass murdering psychopath like he had initially believed 

"Despite the fact I think you are mental for liking sour wolf. You should tell him"

She chuckled at his distain of the alpha. Remembering the conversation distracted her from the reality. Derek was training issac and the shewolf. Again and again they ran at him. Erica smirking as she tried to get closer to him, it was obvious she liked him. The chemo signals were foul and all Y/n could smell when Erica was in the house.

Y/n was sat on the steps next to boyd, she handed him a mug of tea which he took greatfully. She smirked as her old friend threw issac down and then Erica too. Boyd watched her reaction carefully. She sensed his fear and turned,

"We heal boyd. Derek can sense limits and wouldn't go too far. He is somewhat responsible"

Boyd nodded and smiled at her,

"How are you getting on with control boyd?"

He flashed his yellow eyes at her and she returned with her blue ones. He hesitated for a moment and then flicked his hand, claws extending. She smiled at him, pride gleaming in her eyes. Boyd had come to the pack slightly later than the other two and she had shown him more attention. Mainly because he was nervous and closed off, she wanted to help him grow in confidence. But also because she wanted to prove she too was a valuable member of the pack, she knew she needed to establish herself as alpha female at some point, but she didn't know when. It was difficult when the only other she wolf seemed to have all of Derek's attention.

"Better" he mumbled. She nudged into his shoulder,

"You are doing so well!"

Both he and Derek smiled. She realised Derek had been listening and smirked,

"Those two however"

They both laughed and watched as issac and Erica repeated the same moves over and over, Derek throwing them down with very little effort.

"Can someone try something not totally obvious please?!" Derek growled, in a split second Erica had launched herself onto him and kissed Derek. Issac looked over to Y/N whos eyes were glowing. She growled quietly. Issac and boyd were shocked, it was an emotional reaction. She wasn't known for acting irrationally and yet she was. Derek heard her soft growl and threw Erica off. He glanced over to her wiping his face and flashed his eyes for a moment. There was no threat behind it, but it was enough to snap her out of the aggression. He turned back to Erica and snarled

"That is the last time you do that!"

"Why," she groaned as she stood up from the ground,

"Because I'm a beta? Or because of her?"

Erica turned to Y/n and growled, her eyes a glow and her claws out.

"No. Because I have someone else in mind for you"

Derek's response was ignored by both shewolves. It was really because of Y/n, he'd loved her for years but until she growled he didn't think she loved him back. He smirked, an idea forming. It was about time she became the alpha female after all.

Y/n stood and walked over to Erica, completely in control and calm. No fangs no claws not even her eyes had shifted. As she got closer she put herself between Derek and Erica. Derek sighed for a moment and then pulled issac up.
