Teen Wolf: Next Gen

Backstory

Something in his nature had always called her to him. The moment Derek met Stiles in this woods, he immediately felt a desire to scent her and accept her as pack. But he pushed away the urge. She was some random spastic teenager he'd never met before.

On the night of the pool incident, she proved her loyalty. Who else could be worthy of being his mate if not for the young woman that used all the strength in her body to keep him from drowning? He came to her later that night and showed his thanks to her by giving a soft kiss to her cheek.

The moment Stiles met Derek she was overwhelmed by his handsomeness. She masked her attraction with sarcasm, but he could smell the sweetness behind her words. So when he came to her that night with something shining in his eyes other than the red alpha glow, she was shocked  by his gentle kiss. She turned to him, a strong yearning in her heart and returned the kiss to his lips.

It was exactly what he wanted and he hadn't been 100% positive until that moment. His heart surged with passion and he deepened the kiss. They fell back into her bed and caressed each others lips and clothed bodies for hours.

She was still only 16 after all. Her father was the Sheriff and he didn't feel like going back to jail.

They kept it hidden from everyone. After they defeated the Kanima and Jackson moved to London, the new threat of the alpha pack was around the corner. But during the summer, they snuck around, going on dates, enjoying each other's comfort as they cuddled in his loft watching movies and baking desserts.

When they lost Erica and Boyd, in grief they finally let their passion consume them. They gave into their desires. They were a perfect match. As if made for each other.
Their intimacy triggered a hormonal response within Stiles, and her powers awakened. When they awoke the next morning a bright purple glow shined in her eyes.

The Darach made an enormous mistake going after Lydia the night of the memorial concert. Hearing the Banshee's wails, Stiles followed behind Scott to protect the forming member of their pack. Seeing the Darach's eyes turn towards her father erupted a rage within her she didn't know she could hold. And she didn't. The rage erupted from her in a powerful flame, drawing out of her and consuming the Darach within minutes.

Her father stood in udder shock. "What the hell was that?" He asked in disbelief.

"I - I don't know".

Deaton wasn't much help explaining her species. He had only ever heard myths of Kryzskis. Her power stems from her life force. When she mated with an alpha, it created a bond that could only grow as the pack did.
