What the fuck.

That was the only thing running through Katherine's mind as she blinked her brown eyes and focused on her surroundings. She didn't understand what had caught her attention, only that something had, and then realized that it was the shout of her name. In all the time she'd been sitting in the train station — though it looked unbelievably dingy and abandoned, and the lighting was so terrible so she wasn't sure how it was still operational — she couldn't ever remember hearing someone yelling, let alone someone yelling for her,

So she looked around absentmindedly, her brows drawing together as she tried to find the source of the noise.

At first, all she could see was other normal people like herself sitting and waiting patiently. Then, her brown eyes focused on the form of a tall boy with floppy dark hair that looked a lot like her dressed in dark pants and a dark shirt, sneakers and a red flannel. He was racing towards her frantically, as if he'd rather die than have her out of his sight, and he cried out a name that triggered a small flicker of recognition.

"KitKat!"

Her mouth opened wide as if she wanted to respond to him, to yell back but to save her life she couldn't figure out why so she closed it. She didn't remember having ever seen this boy before in all of her nearly-sixteen years on Earth. But he was racing over to her with determination set on his face, his footsteps hammering across the old concrete ground like there was no tomorrow.

The flicker of recognition grew into a spark as she continued to stare at him and her mouth opened again, only this time it formed a word that seemed to shatter some kind of wall that had been put up in her memory; Stiles.

She looked down at her arm as the memories came back to her and she could still see the faint remains of sharpie on it from where she'd written that familiar word not too long ago, and looked back up at him as shock flooded her body. Before she could come up with a coherent thought, Katherine was off the wooden bench and sprinting towards him as well, her heart hammering in her chest.

He's real.

Stiles is real.

She slammed into his chest with a horrible thud! but didn't even stumble back or pay any attention to the ache that flared through her body upon impact, just hooked her arms around his neck and burst into tears when she was lifted off the ground. The feeling of his arms around her was all-too-familiar to her, and now that she could feel it she knew what had been wrong during that awful week of her life.

It was that her brother was real, and she didn't know that.

"Oh my god!" She cried out, burying her face into the comforting smell of his flannel as he held her as tightly as his body was capable of. Katherine found herself grabbing a hold of the back of his sweater as if she were afraid he'd disappear, because in truth, she was. After spending more than a week feeling the way she had, as if her world were ending, she never wanted to feel that way again. "Oh my god Stiles! You're really real! You're — they — they said I made you up but you're—"

"I'm right here, I swear to god I am right here, okay?" His arms tightened around her, and even though she could feel his muscles trembling as they cried out for her to be put down, so he was forced to set her down on the ground. But he didn't let her go, just continued to hold her as tightly as he could in her grasp as they sunk down to their knees and carefully pulled away, hands still on her shoulders. "Are you hurt? Are you hurt at all? How did you get here?"

Katherine looked up at him with a watery smile; just seeing him made her feel warm and safe and okay. "I couldn't forget about you," she whispered, showing him the faint black ink on her arm. "Mom and Dad, they...they put me in Eichen because I was so completely positive you were real; they thought I was crazy."

He stared at her in shock. "Mom?"

It took her another long moment to remember why he was so surprised. "Fuck, she's not — oh my go this is all so confusing." She was swatted on the back of the head for her choice of words, and immediately threw herself into his arms again. "I really really missed you, Stiles."

"Why didn't you forget me? You can't outsmart a supernatural force of nature, KitKat, no matter how much you want to," he murmured, pressing a kissed to the top of her head.

Katherine just hid her face in the crook of his neck; they were still a messy pile of limbs and tears on the train station floor. "You raised me, Stiles, after mom...after she died." She'd just gotten used to the idea of having her mom around again, so it was a harsh reminder to say she was dead. "When Dad had to work late every night for years just to make up for having only one source of income, you were the one who showed me how to do fucking long division and — and the one who packed my lunch for me, who tied my shoes before I learned how to...you're...if it wasn't for you, Stiles, I'd probably be a whole lot worse than I am now.

"So yes, my mind forgot you." She blinked back tears as she stared up at him. "But my body didn't, and that was so much worse. You are the other and better half of me, Stiles; you're the Joey to my Chandler—"

"—no way are you Chandler—"

"—Shut up dude, you're the Joey to my Chandler and it wouldn't be right if we were apart, okay? You're my big brother, Stiles. How could I forget you?"

He stared at her for a long moment, eyes teary, and then exhaled a shaky breath while wiping his palms on his thighs. "I love you too, Katherine. Then Stiles pursed his lips. "Okay now that you're awake, you me and Peter—"

"—Peter? As in Peter Hale? Are you fucking kidding me?"

Stiles rolled his eyes at her. "Unfortunately no. Now come on."

"I thought he died?"

"I wasn't dead," a familiar mans voice scoffed as Peter's leather-jacket-clad frame appeared from behind one of the several pillars holding up the ceiling. "I was in Eichen House."

Katherine stared at him. "Dude, same difference."

After that she grabbed Stiles' hand and followed him off to the other end of the massive gaping room where a dust-covered door was visible within the wall, though it was closed. "It's got some kind of radio in there, maybe a intercom."

"We could find a way to reach the other's with it," she murmured aloud, following his plan easily. At the mention of the others in the pack she froze, her last moments with them coming to mind and she gasped out loud. "Oh my god. Oh my fucking god.

"What?"

"Stiles!"

"What?"

"Stiles I kissed Liam! I kissed him!" Her hands flew up to cover her mouth. "Oh my god I'm a terrible person I'm literally the worst. I'm almost as bad as — I was going to say as bad as Peter but he's Peter so that's debatable but oh my god Stiles! What the fuck is wrong with me?"

But she was dragged into the room as Peter opened the door, and then her mind was elsewhere. It wasn't enough to drown out the self-hate filled horror, but it was a start. She was crawling around on her hands and knees across the dusty floor of the dimly lit room looking around through the ancient wires, though she wasn't sure what for, trying to tune out an extremely annoying Peter as she did so.

"Your theory is ridiculous," he muttered, pacing back and forth across the same strip of floor. "Magnetic disturbances and a few pixelated photos doesn't mean that you can use a ham radio to communicate across a supernatural barrier. Ghost Riders can't be seen, heard, or remembered. You really think they're gonna leave a gadget around that you can use to call your friends?"

She glanced up at the sound of something annoyingly high-pitched and shrieky that hurt her ears, and looked a Peter in surprise. He'd twisted a random dial on the wall which had caused the noise, and immediately stepped back as Stiles spazzed his way over to it.

Eventually, as she had no idea how to operate the finicky, cob-web covered technology that probably shouldn't work in the first place, Katherine wound up sitting on one of several cluttered desks that was in front of her brother as he fiddled with various nobs and switches, hoping to make something else work.

"Take your time," Peter muttered sarcastically. His arms were folded over his chest as he leaned against one of the other desks in the room. "No rush."

"Literally shut up, please," Katherine huffed as she shot him a glare.

He ignored her. "Only thing at stake is any evidence of our existence...soon to be lost... forever."

"Okay, not helping," Stiles snapped sarcastically, lips pursed.

Before Katherine could fire an insult at him, Peter's expression switched to terror in an instant and he was racing over to the wires Stiles had patched into the operating board and yanked them out, and then he froze and listened.

She had enough contact with the supernatural world to know she should be still and silent, too.

But she let out a small squeak when she was hauled over Peter's shoulder, and then her and Stiles were dragged out of the radio room and out into the station where he hid them behind a pillar.

Her heart hammered in terror as she watched a ghost rider dismount his ghoulish horse and kick the radio room door in, his magical gun drawn.

It felt like she'd stopped breathing.

"In case you're keeping count, that's twice I've saved your life today," Peter hissed to her brother.

She was too frozen to snark back at him, and he'd sauntered away before she'd regained her bearings.

Instead of chasing after him she decided to sit down with Stiles, their backs against the station wall. Katherine hooked both her arms around his left one and curled her body into his side, feeling tears well up in her eyes.

As he was always able to, Stiles pulled her into his lap and held her tightly against him since she didn't have a weighted blanket, his chin on top of her head. "We'll get home, okay?" He promised her softly, threading his fingers through the tangles in her hair. "I'll find a way to get you home so that you can confess all your messy teenage feelings to Liam, and sort everything out with him and Hayden and just be happy, and—"

"—and so you can get back to Lydia," Katherine interrupted him softly, her cheek against his chest.

She heard him inhale sharply. "Yeah; so I can get back to Lydia."

The two of them sat there in silence for a moment, just listening to the utter silence that surrounded them until Katherine sighed. "She loves you back, you know? She's just..."

"She's scared the same way you're scared to tell Liam?" He guessed bluntly.

She gaped up at him. "Okay seriously? You really want to make fun of me for being a chicken when you literally created a 10 year plan to make Lydia fall in love with you? Really dude?"

"First of all; don't diss the 10 year plan, you just proved that it's working. Second off, we started off as the nerdy guy and popular girl. You and Liam basically started off as best friends. It's not the same."

"It started off with Liam bruising my ribs with a chair after Scott kidnapped him...wait no! It started off with him saving me from a broken nose!"

"Exactly my point."

"Dude, shut up."
