Caitlin's Powers

Disclaimer: Something I've had in mind for awhile now as a crossover between The Flash and Teen Wolf but with Caitlin's mother having something different to say about where she thinks her daughter's powers are coming from. In this idea, Caitlin (as the oldest of the trio by about 15 years) and Lydia are siblings while Stiles is their step brother after his dad and the girls' mother got married. TW events happened in the mid to late 90's. Allison and Aiden survived their stab wounds (cause screw that nonsense) and Kira has yet to return.


Some time after having made her video message to her eldest child, Natalie Snow-Stilinski made her arrival to the town of Beacon Hills, California. A place she hadn't been too in some years as she had buried herself in her work following the death of her husband, Noah Stilinski. Who'd been the town Sheriff for a good number of years until losing his life in the war Gerard Argent had started in his quest to wipe out anything Supernatural. A war he and his had ended up losing thanks to a plan of Scott's involving Law Enforcement. Needless to say, Scott had been pretty surprised to hear from Natalie since no one aside from Stiles and Lydia had kept in contact with her since Noah's death. Though his two friends' contact with her had been sporadic at best considering the fact she'd buried herself in work and the like to escape her grief. Which kept her from knowing of a great deal of things regarding her three children. Learning her oldest had been married for a painfully short time had made the mother of three's heart clench painfully and began to wonder if perhaps it was time to end her cold distance and get back into the lives of her three children before something truly horrible happened and prevented any chances at reconnecting.

And as she drove on to the old Animal Clinic for her meeting with Scott, Natalie couldn't help but marvel at how dead the town was beginning to look. Knowing that the loss of the Nemeton was clearly having something to do with it thanks to an email she recalled receiving from Lydia roughly two years ago. Telling her of how Scott of all people had chosen to destroy it in order to prevent it from no longer bringing in more problems for the town. This had put him in hot water with some circles but the worn out Alpha hadn't given a single crap and went on about his business. Natalie couldn't help but wonder how much longer it'd be before Scott himself left the area since it was dying. She was broken out of her musings once she reached the Animal Clinic and saw several vehicles present. Among those being that old Jeep of her son's that he refused to part ways with no matter what was said or done. The Clinic had been the designated meeting spot for her to come too in order to discuss her idea about where exactly Caitlin's powers were coming from. As to her, it felt a bit more was going on then just delayed after effects of the Particle Accelerator explosion. A head popped out from the raised hood of the Jeep and it made the Scientist smile.

As it was none other then Stiles himself! Who gave a wide happy smile at the sight of his step mother and came over to greet her with a hug once she got out of her rental. "I knew Scott said you were comin', but I found it hard to believe until I saw it with my own eyes!" Declared her youngest happily as they hugged.

Natalie felt a pang in her chest over his words, knowing full well why he would have trouble believing until otherwise. Another reason to change things…

"Well, I live to surprise." Natalie replied a bit flippantly to hide her feelings as they pulled back from one another.

But Stiles it seemed saw right through her with the knowing look he gave her. "So, Scott said you needed some input about somethin'?" Asked the young Deputy as they made their way inside the Clinic.

"Yes, as it seems something is going on with your older sister."

"What? What do you mean by that?" Stiles asked in worry as last he knew, things were okay for her.

Or as okay as they could be when she lived in a city with people who had super powers. But he wouldn't get his answer as they would be interrupted by Lydia rushing to the two and hugging their mom happily. "Ohh its so good to have you here and not in that stupid lab." Declared Lydia happily.

Even though she knew why her mother did it but still. Naalie couldn't help but chuckle as she held her little girl. "Your brother said the same thing, sweetheart."

"Well, even he can be right on occasion." Smirked the Genius Redhead and earning an offended 'hey!' from Stiles.

Earning chuckles from the two Martin-Stilinski ladies and the others nearby. Among those being a goatee having Scott with a shaved head who came over and gave his former teacher a hug. "Its good to see you again, Mrs. Martin." Scott said warmly once they parted from the hug.

Martin having been her first husband's last name until taking Noah's. "And you as well, Scott. And I thank you for taking the time to hear me out."

"Of course, its not a problem."

"It is for me, what's goin' on with Cait!?" Demanded to know Stiles irately and gaining a look of confusion from Lydia.

Natalie sighed at the impatienceness of her son but decided to answer him. "Your sister came to me with a… Well… A problem."

"What kind of problem?" Wondered Lydia worriedly.

"It seems she's gained ice related abilities..."

"Ice related abilities? Would this have to do with that Particle Accelerator explosion from almost 3 years ago?" Alan Deaton asked curiously.

Natalie shook her head. "No, my gut is telling me that it has less to do with that and more to do with the Supernatural. As most cases with that explosion tended to show something within a short time frame."

Deaton nodded at that. "Understandable but it could still none the less be a delayed reaction. Or, perhaps it simply unlocked something within your daughter that was already there."

"And given the fact I'm a Banshee on mom's side of the family, there's no telling what that could be." Added Lydia thoughtfully.

"What if its a Jotunheimr kinda thing?" Spoke up a heavy set girl that had been mostly quiet until then.

Causing all eyes to turn to her and making her gulp some. "A what, Alice?" Asked Scott of his Beta.

Alice, a born Wolf who'd came to Scott 3 years previously in the hopes of joining his Pack after wondering around for a good period of time on her own as an Omega. She'd also been a victim of Gerard's attempt at Genocide as well. "Jotunheimer? The land of the Frost Giants of Norse Mythology?"

Everyone thought about that for a moment in silence before Deaton broke it. "Well… Its certainly possible. Though given the fact there's not been any sightings of Frost Giants in centuries makes the possibility a very small one."

"And Thomas was very human." Recalled Natalie.

Lydia looked thoughtful for a moment as Stiles gaped at his mom in shock over his oldest sibling's apparent new abilities! Hell, Caitlin didn't even know about the existence of the Supernatural for crying out loud! As they had felt it was for the best given some of the dangers that the Supernatural had. "Wait… Didn't daddy joke sometimes about his mom being a huge frigid woman?"

"Well… Yes… But I hardly think that means anything!"

"What about when he somehow managed to freeze the pool during the hottest days of the Summer?" Countered Lydia.

Vaguely recalling him looking a little blue too once or twice as well! Natalie was about to say something to that when an old memory came to mind. One of how Thomas acted like the coldest times of the year was just another warm day. Even thinking his blue skin at the time was just from the cold air that was beginning to effect him, getting her to force him inside before he got himself really sick. "So… Cait's a Frost Giant huh? Why not." Muttered Stiles sarcastically.

"If this is true, she will need to learn how to control it before something fatal happens." Deaton warned grimly.

A grimace came across Natalie's face after that. "Well, she's already helpfully given a former employee an unfortunate case of frost bite. But that was more his own fault for being a fool looking to make a buck. But I agree with you Alan."

"Training a half Frost Giant is kinda out of my area, but I could try and do so anyway." Offered Scott as he looked towards Natalie.

Who looked grateful for his offer, knowing he would do what he could to help her oldest with her new strange abilities. "Business is slow so you leaving for a few days wouldn't hurt anything." Deaton said with a small shrug.

Of course slow would be an understatement considering the way things were going. "I'm comin' with." Stiles declared adamantly.

Lydia voiced her intent as well and Scott merely nodded. "I'm sure your sister will greatly appreciate the support from you two. And you as well Scott."

"Been too long since I've seen my sister anyway, so this will be a great way to catch up on everything." Lydia said happily.

Maybe give a much needed hug where Ronnie was concerned as well.

2 Days Later at STAR Labs In Central City, Missouri

"CAIT!" Cried out both Stiles and Lydia once they got inside and met her halfway with a smiling Scott trailing along behind.

"Lydia! Miec!" Caitlin cried out happily as the trio had a heartfelt hugging moment.

"What, what are you two doing here?"

"Well, mom came to Beacon Hills and told us what was going on with your powers." Began Lydia.

"And we decided to come and see you to help you deal with this." Added in Stiles.

Their replies throwing the good Doctor Snow off a good deal. "But… And no offense, what could you two possibly be able to do as its definitely outside of your areas?"

She watched as the two exchanged looks before looking to her. "What do you know of the Supernatural?" Lydia asked curiously.

"Does reincarnation for two people with wings count? Cause I know about that. And the guy threatening Star City has magical powers according to a friend of mine over there." Replied Caitlin while wondering if she should say more.

And wondering what that question had to do with anything going on with her. "Well, this makes things a bit easier then." Stiles muttered.

"What do you mean?"

"Lemme put it this way, sis... Lydia, me, and our friend behind us have been dealin' with the Supernatural since the mid to late 90's. Mom has too kinda. And its… Its why dad um, yeah."

Caitlin was greatly surprised to hear that, especially where dad was concerned and she so badly wanted to know what exactly got their dad killed. She also took note of the friend in question behind the two and her breath ended up caught in her throat as she looked at him. And it seemed he was having something of a similar reaction given the way he had frozen at the sight of her. Lydia and Stiles took notice of this and looked at one another with knowing smiles on their faces. "Cait, this is Scott McCall, my long time best friend and brother in all but blood from Beacon Hills." Introduced Stiles with a wave of his hands in his best friend's direction.

"He's also gonna be the one to show you how to control your new skill too." Added in Lydia helpfully.

Not that her older sister was paying much attention of course!
