Take-off story after Season 3, Episode 9 "The Girl Who Knew Too Much" SPOILERS be warned. Major Stydia action with a little smut, but pretty much PG-13.
Chapter 1: Banshee
She walked confidently down the hallway, ignoring dangerous looks from the twins, who were now more attentive than ever upon realizing that she too was a dark creature. She could become the new enemy, maybe even join forces with Scott, the 'true alpha' now that she was aware of her power.
"Lydia, can we talk?"
Stiles was in front of her locker, with his arms crossed, looking determined. He wore his usual – plaid button-up with jeans. This always annoyed the fashion-forward Lydia, who at the moment was wearing chambray tucked into a short pleather skirt with five-inch heels. She rolled her eyes at him, not wanting to discuss the previous night, even if he had technically saved her life.
Ms. Blake was strangling her, and she screamed, so loudly that anyone within a mile or a wolf within five miles could hear it. She was going to die, now that she finally knew what she was. A banshee.
Scott and Stiles came rushing in, but Scott was no match for whatever Ms. Blake really was, which remained a mystery. Temporarily able to breathe, Lydia coughed, her throat constricted, gasping for air.
Carrying her, Stiles made for the exit but was cut short by Ms. Blake. Luckily, Allison's dad Mr. Argent, had turned up out of nowhere and shot her with an arrow. Screeching, Ms. Blake dived through the window and escaped into the night.
"What?" said Lydia with hostility in response to Stiles.
His brown eyes searched her over wordlessly, like he was trying to find the right thing to say. She just managed to find this more irritating, and started to walk away, Stiles following like a puppy dog.
"Can I at least say I'm glad you're not in league with the demon-god. Or Deucalion," said Stiles, "I mean a banshee, we can work with that."
"What do you mean 'we'?" Lydia said, turning toward him, giving him her bitch stare. "I am not signing up for to be in your wolf pack, or whatever."
"I'm not a wolf, so really that wouldn't…" he began, but she had turned back around and was walking toward Allison on the other side of the hall. "Can I at least come to your party tonight?"
"No," she responded, continuing her natural cat strut on her way to her best friend, Allison. But then something happened she wasn't prepared for. In through the doors walked a tall, gorgeous guy with killer blue-green eyes and a body that would make any girl drool. It was Lydia's ex-boyfriend Jackson.
"Oh my god," she said, and dropped the school books she was holding. Running at him, she jumped into his arms, and kissed him feverishly. He grinned at this, holding her tiny five-foot frame up around his body.
"It's good to see you too, babe," said Jackson.
From behind them, Stiles watched the scene, aghast. He had finally had his chance with Lydia. And now it was gone.
