Summary:
Kate's life is going fine. Lonely and small, but fine. She's learning all she can about her magical heritage, and it's going pretty well, she thinks.
Then two cocky vampires walk through the door of her shop, and her fine life is turned ass over teakettle. Richie is unnerving, and Seth is just an asshole. But apparently she's supposed to help them, according to some tea leaf reading (really, universe?), because it's her destiny. Or whatever.
Also, what the hell is a soulmate?
Written for AU August 2025! Prompt was witchcraft. Also? Unbeta'd. 🫠

“Is that… Are you…wearing my shirt?”
“Oh. Yeah,” she said, hoping it came out as casual as it sounded in her head. “You left it in the dryer, and it was really soft, so—"
“So you stole it?”
“Borrowed! I was gonna give it back.” Lie. That was a big, fat lie. “But I…” Kate trailed off when she looked over to find Seth smirking at her. Nudged him as she admitted defeat: “Fine. Yes. I did. I stole your henley. And you’re never getting it back.”
“And here I thought the dryer musta eaten it, you little thief,” he said, tapping her thigh twice over the blanket before lacing his fingers behind his head again. Completely unaware of the havoc he’d just wrought on her senses. “Preacher’s daughter strikes again,” he mused.
@myletternevercame and @tuntematonkorppi and I have been bitching about our feelings of want-to-write-but-no-not-that-only-want-no-actual-write for a while, and then I made myself write this, instead of, you know, any one of the 800 WIPs that I want to write.
And did I intend to finish this BEFORE New Year’s Eve? Probably. But as with You Squeeze My Hand Three Times, well, that didn’t happen and I ended up writing most of it DURING NYE instead. As one does. At least the words happened. The first week of January doesn’t count anyway.

Of all the scars Kate came away with, the one on her palm is the one Seth worries the most.
Literally.
Aka: Seth Gecko just wants to hold Kate Fuller’s hand, the fic
It wasn’t the first time Seth Gecko felt like he was lost and it wouldn’t be the last time, well then again maybe it would be. He was fucking cold and there was no end in sight to snow falling around him. He knew better than to sit down, but he was so damn tired. His legs were stiff and fighting through the snowdrifts wasn't getting any easier. He kept moving toward the obscure light in the distance. He could practically hear Richie’s voice in his head yammering about the odds of survival being better if he’d stayed in the vehicle. But Seth couldn’t risk being found in a stolen car.
The ground under the snow was uneven and while he’d been stumbling for the last, for however long he’d been walking, he finally tripped. He hit the cold snow face first. Fuck him. He was done. He closed his eyes and hoped hell would at least be warm when he crossed over.
“Are you happy now? He’s in your truck. You don’t even know the guy. What if he’s some kind of criminal?” There was an angry, male voice muffled, but close.
Oh, he wasn’t dead. He was warmer too. The whine of a heater and the smell of flowers was all around him.
“Kyle, I wasn’t gonna leave him in the snow. He was facedown and there isn’t a car for miles! He could have died! I’m takin’ him to the hospital and that's that. It’s fine.” A woman’s voice, possibly angrier than the guy.
Seth wanted to raise his head and look, but also didn’t want to press his luck. A hospital wasn’t really an option. One look at his wallet and he was as good as handcuffed or worse in a small town. Backroads were good for avoiding getting caught, until you got caught.
“Katie, I know you said going out into the world was good for you, but you’ve changed and you’re taking risks that the girl I knew would have never.”
“First of all don’t call me Katie, it’s Kate. Second, I am helping someone and I learned that in church. And third, it’s none of your concern what I do, I just needed your help with his weight”
“Kate, I know you’re this angry with me. But this trip was your idea.”
“This trip was my idea for us! Until you and I quote ‘didn’t mean for me to find out about her’ when I caught you naked on the couch with a girl you were supposed to be teaching to play guitar.”
“That’s not exactly…”
“It’s exactly what happened. And now you’ve got the nerve to show up with her to a trip that I planned for us. What did you think was going to happen?” There was a long pause then an exasperated scream from the woman, “You're a moron! You thought it was going to be okay if you were sleeping with both of us? I’m going to stay at another hotel tonight and then I’m driving home tomorrow, alone. You made your bed now you can sleep in it, with her, because you’re certainly never getting into my pants again!”
Hmm. Seth couldn’t help the smirk that formed on his lips. He was a sucker for a spitfire. The truck door slammed and a small hand pressed against his forehead.
“A little warmer. That’s good. Let’s get this other blanket on you. I warmed it up on the vents on my side.”
A soft and warm blanket was tucked around him. He tried to stay relaxed to fake being asleep but it was getting harder.
“We’ll get you to the hospital and they’ll be able to thaw you out better than me.”
He grimaced so much for enjoying the warmth and peace for a minute. He shifted and while startled to be nose-to-nose with the kindhearted woman. Her eyes were hazel. Kate had hazel eyes and looked like the-girl-next-door from all the best Hollywood films. He tried to ignore her panicked expression and kept his game face on. He narrowed his eyebrows and did his best to sound threatening. “No. No hospitals.”
She blinked. “The hospital won’t care if you don’t have insurance. They need to treat you if you come in.”
Oh, that was adorable. She thought he was worried about money. He tried to move, but his muscles burned in protest.
“I can’t go to a hospital. Hospitals call the law.” He had a gun on him, but he really didn’t want to point it at her. However, he also really didn’t want to get caught.
“Oh. Oh!” She looked nervous and glanced back at the other car, which was already pulling away. “I can give you the truck and I have some money, but I did save you from the cold, so I think it’s only fair if you don’t leave me out there to freeze.”
She was practical. He’d give her that. “I don’t wanna leave you in the cold. I just need to warm up and call my brother to come get me. Hand over your cellphone, please.” He wasn’t taking the risk of her just bailing out and calling the cops.
“What did you do?” She folded her arms over her chest.
“What?”
“What. Did. You. Do.” Kate spoke slowly pausing at each word before continuing, “If you’re a thief or someone just trying to make money that’s one thing. But if your a rapist or something, I’mma pepper-spray you and kick out you out of my truck.”
“You shouldn’t tell people if you’re going to attack them." He explained exasperated at her ill-advised warning. "That’s not a good strategy for dealing with a criminal.”
She arched her eyebrow. “Try to move right now.”
Seth ground his teeth and she was right. He could barely move.
“You sound like you’re from Texas. The winters are harsher up here in Colorado. I know how your body’s reacting right now. I don’t want to hurt you, but I also don’t want you to hurt me. What did you do?”
“Stole a bunch of cash with my brother. I was the distractions while he got away with the take.”
“Okay.”
“Okay?” Seth was confused. She was okay with him? Just like that? Who the hell was this girl?
“Yup.” She buckled her seatbelt and the truck lurched back onto the road. “I’m Kate by the way.”
He should give her a fake name. But did it matter? Probably, not, so he opted for abridged honesty. “I’m Seth. Where are we headed?”
“Well Seth, since you don’t want a hospital I’m gonna take you to the local ‘no questions’ motel.”
“You seem like too nice a girl to know about places like that.” He noticed the snow had stopped. How long had he been face down? He licked his lips, they lasted like cherries. That was weird.
“Gotta have a spot to party after prom, for ya know.” She blushed and fiddled with the radio.
Seth barked out a laugh and immediately regretted it. He started coughing and folded himself into a ball to try and stop it. Kate put a hand on his back.
“There’s coffee in the mug in the cup holder, you’re welcome to it.”
She removed her hand and he instantly felt colder. He took a drink of the lukewarm, bitter liquid and shuttered at how cold he still was. They drove in silence for a bit then the motel came into view. Damnit he was closer to shelter than he thought. He should have forced himself to keep going, kept this girl outta his mess.
“Keep your head down. Sign says there are cameras so it probably points out at the parking lot.” She clicked on the turning signal and the truck began to slow down.
“You a secret criminal? Seem to know alot about this stuff, Princess.” Seth pulled the blanket over his head.
She chuckled, “Naw, just listen to a bunch of true-crime podcasts. And I'm no one's princess, Seth. Just ask my ex.” She was out of the truck and back in less than five minutes. The truck reversed and rolled slowly until parking again. Kate sighed heavily. “This weekend is far crazier than I planned it to be.”
He pulled the blanket down and made eye contact with her. “Why are you helping me? I don’t understand. It’s one thing if you just thought you were helping out some dumbass in the snow, but you know I’m dangerous. Why are you doing this?”
She inclined her head to the side as if considering his words. “I guess, I wanna help you. Come on we need to get you warm and dry.”
None of that was a real answer, but Kate was out of the truck and opening the door on his side before he could question further. He managed to get his feet on the ground but stumbled immediately. Expecting to hit the ground again he winced, but instead, Kate grunted and held him up.
“Just shuffle with me. It’ll get better if you move.”
They managed to get into the small room and Kate helped him sit on the bed.
“I’ll be right back.”
Every criminal lesson he’d ever learned was screaming for him to pull his gun on her and keep her in sight, but he flopped on his back on the bed. If she bailed and called the cops, so be it, at least he wasn’t gonna freeze to death.
The door opened and he pushed himself up on reflex but failed to pull his gun because it wasn’t there…How had he just fucking noticed that? His hand patted the back of his pants where he'd left it, but nothing. Fuck, had he lost it in the snow?
“Oh, yeah, I took that when I got you into my truck.” Kate kicked the front door closed with her foot and was holding an armful of what looked like Christmas presents.
“You knew I was armed and you still helped me?!? Are you insane?!?” Seth was freaking out. He wasn’t gonna hurt her, but he could have. Where was this girl’s self-preservation? He could have murdered her or worse and she just helped him anyway? What the hell?
Kate looked annoyed. “It’s Texas. I have a gun, but it’s at my house. Although, I have yours so technically I am armed at the moment and you’re not.”
He blinked a few times as the situation fully set in. Seth was going with it, whatever was happening, was happening, whether he got it or not. “What’s with all that?”
“Well, we need to get you warm and dry. So you’re gonna take a shower and we’ll lay out your things to dry. But I didn’t figure you'd want to be naked. So you’re gonna be stuck with the pajamas I bought my dad for Christmas.” She started unwrapping one of the boxes, unshed tears clinging to her lashes. “Frostbite is a bitch and you don’t want it. This is an object and you are a person, regardless of whatever, you were up to before. You shouldn’t be left alone to suffer and die.”
His brain short-circuited for a moment. Why was she so worried about him? “Did I miss something? You okay?”
“You were almost dead.” A single tear ran down her cheek, as she looked into his eyes. “I saw you in the snowdrift but I panicked. Thought it might be a trick to rob me, so I called Kyle, my ex-boyfriend, because I knew he close by. Then I sat there in the truck and watched you while I waited. I realized you were too still. I got out to check on you in spite of everything and you weren’t breathing. I almost let you die, because I was worried about getting robbed.” She drew in a shaky breath, “I was more worried about my purse than a person. What’s wrong with me?"
She was clinging to the white box in her hands like a lifeline as if she had something to feel guilty about. "I gave you CPR and thank god you responded. Kyle pulled up as you gasped and then I saw the gun. Everything just happened so fast.”
Her voice was barely above a whisper. “If you save someone’s life, you’re responsible for them. I couldn’t just let you die.”
Seth toed off his shoes and forced himself up to his feet, unsteadier than he liked. He paced over to the still-trembling girl, resting one arm against the door over her head. He leaned into her space and tipped up her chin, before kissing her forehead. “Thank you, Kate.”
The boxes clattered to the floor and she wrapped her arms around his waist hugging him tightly. Seth looped one arm around her, but the other arm he kept braced against the wall. He didn’t trust himself to hold his entire weight.
“This is so stupid.” She muttered into his chest. “I don’t even know you.”
“Just makes you a good person. I on the other hand am a bastard. But for the time being, I owe you, so I’m your bastard.”
Kate’s laugh was instant, which made him smile as she warned. “Don’t give me that much power.”
Mischief sparked in Seth’s eyes and he forced her to look at him, “Why? You wanna take advantage of me?”
“Um, you should get in the shower and warm up.” Kate’s cheeks instantly stained pink. “Get your wet clothes off for sure.”
“Okay.” He smirked and took half a step back shrugging off his coat and loosening his tie before dropping it to the floor. He didn’t miss Kate's hard swallow at his movements. “Might need help with the buttons. My fingers aren’t working all the way.”
“Sure.” She moved back into his space, biting down on her lower lip as she undid the buttons to his waist. “I’m just gonna untuck this okay?”
“Yeah. I trust ya. Thanks for the help.” He couldn’t keep smile off his face, not that the blushing woman could see it, as her eyes were on the fabric directly in front of her.
“You’re…you’re welcome.” She finished the buttons and went to move away, but he looped his arm back around his waist pulling her flush to him.
“Katie, I just thought of something.”
“Mhmm.”
“I’m gonna need you to test the water before I take that shower. I might not know how hot it is, that would be bad.” He calculated the risk and cupped her cheek coaxing her closer, ghosting his lips over hers. “You wanna help me with that shower, Princess? I can show you how grateful I am for the rescue. No strings, no pressure.”
.:. 8am .:.
Richie Gecko knocked on the motel room door. Jesus, he hated the cold. Seth, missing a shirt and wearing the gaudiest pair of green Christmas-themed sleep pants he’d ever seen, opened the door.
“Did I miss something?” He adjusted his glasses as he entered the room and shut the door behind him. “You rob one of Santa’s elves for a new outfit?”
"Limited options available." Seth rolled his eyes and patted the suit hanging over the motel heater. “Almost dry.”
Richie was even more confused looking around room at the unmade bed and wrapping paper all over the floor. “Did you steal someone’s Christmas presents? That’s wrong, even for us.”
He might have continued his rant further but the bathroom door opened and a slip of a woman exited came into the room sporting a top that matched what his brother was wearing.
“Hi.” The auburn-haired girl offered a meek wave.
“Seth.”
“Richard.”
“Did you kidnap a girl?”
“I saved him from freezing to death actually.” She lifted her chin, “and my name is Kate.”
Richie was exasperated.“I left you alone for less than twenty-four hours. How did you almost die and pick up a chick in that timeframe?”
“I have a particular set of skills.” Seth bit into a piece of jerky and offered a piece to his brother who waved it away.
Kate giggled and covered her legs with the motel bedspread.
“Is this a thing now?” Richie questioned.
Seth shrugged. “If she wants it to be.”
Kate smiled as she braided her hair back.
“You are,” Richie smacked his hand on his forehead, growling at his brother, “as bad as a Disney princess. Five minutes and you catch feelings.”
“It was longer than five minutes.” Kate supplied then yelped and pulled the blanket over her head to hide in what was likely embarrassment.
“Great. Compliment him.” Richie deadpanned before admonishing, “I hope you’re happy, 'cause he’ll never want you to leave now.”
“She can cook and she has a truck we can use to get over the border.” Seth flopped on the bed next to Kate.
“And now we’re a trio.” Richie took out his pack of cigarettes. “I’mma go smoke both of you put on some more clothes while I do that.”

summary: They leave Matanzas without Kate. It doesn't sit right with Seth. (just about at the end of 3x10)
They're five miles down the road before Seth slams his foot on the brake so hard that Richie's head goes into the dashboard.
“What the fuck, brother?” Richie screeches, slamming himself back into a sitting position.
Seth sits there, car idling, hands gripped around the steering wheel.
“We forgot Kate.”
“What do you mean, 'we forgot Kate'? She's alive, demon free, with her whole life ahead of her. We just saw her three minutes ago. There is no forgetting Kate.” There's no one coming or going, not on this stretch of hole filled, long abandoned road.
Matanzas is still in the rear view, empty, desolate; a ghost town brought to life and painted with blood only to be laid to rest again.
“What the fuck is she going to do, Richard?” he demands. “We just left her in the middle of fucking nowhere, Texas, without a ride. Without money. Without any kind of identification. And she looks like she just wandered out of the other end of a Hot Topic.”
Richie holds up a hand, says, “Technically, she and I did just come back from an all expenses paid trip in Hell. Which, you know. Is basically Hot Topic.”
“We can't just leave her there,” Seth says after a moment of silence. He puts the car back into first, kills it as he takes his foot off the clutch for the first time since he was twelve.
“I wasn't suggesting that.”
“We have to go back for her, Richard. She's--”
“Seth. I just agreed that we need to go back for her.”
The elder Gecko kills the car again, so that they're sitting sideways in the road, taking up both lanes.
“Do you want me to drive? Because I'll drive. You'll fuck up the clutch if you keep doing that.”
“Why did we even leave her there in the first place?” He manages to get the car turned around and guns it, shifting from first to second to third to fourth in quick, practiced succession. “We shouldn't have left her there.”
“I thought she'd follow us!”
“And you didn't say anything when she didn't?!”
“It was her decision to make! She didn't want to go with her own brother, for fuck's sake!”
Matanzas is growing larger and larger with each breath they take; Seth is clearly not doing to speed limit, though numbers like that have never mattered to him.
“One of us should have offered.” And then, quieter, “I should have offered.”
The ghost town looms before them, quiet and desolate. It's funny, Seth thinks, to know that there's only one person alive amidst the rotting old wood and six inches of dust.
He turns off the car; they sit there in silence, listening to the radiator drip as it cools.
“Do you need me to hold your hand.” Richie finally says, “or are you going to grow a pair and go get her? I'd go myself but, uh. Sunlight. And I'm tired.”
“Really, Richard? You're tired?”
“Hey! Hell and back, remember?”
He raises a hand, slams it back down on the steering wheel halfheartedly. He doesn't have much in the way of arguments, not right now, not after everything they've been through in the past few months—hell, past few hours.
Instead of answering Richie, he shoulders the door open and slams it shut behind him, cutting off any kind of parting riposte his brother might think up.
The air is already oppressive at this hour of the morning, and he can feel the dirt and blood and sweat caked on his clothes and skin solidify a bit more under the Texas sun.
It's a simple matter of retracing his steps, taken less than ten minutes before, to find Kate Fuller. But he goes slowly, events of the previous twenty four hours catching up with him, weighing down him bones. The heat might be part of it, too.
The town has gone silent again, nothing but a stiff, humid breeze kicking up dust around him and breezing through ancient broken windows, whistling through the spaces between the wood. There's blood still on the air, drying quickly, the hint of it just enough to make his stomach turn.
She's sitting on one of the dusty old porches in a strip of sunlight, face tilted up and eyes closed. The makeup Amaru had applied to her eyes is smudged, almost all the way up to her temple, like she tried to scrub it away with her hands.
He knows that there's things Amaru did to her, things Amaru made her body do, that can't just be scrubbed away.
Her hands are folded in her lap, fingers threaded together, like she was trying to pray but forgot how. Her hair, red tinged (blood, he thinks, unbidden), sits in clumps around her shoulders, humidity already doing it's work.
Seth clears his throat, and she jumps, shoulder's stiffening and hands going into fists. Kate relaxes a bit once she catches sight of him, hands uncurling , all of the fight draining out of her body at once.
They stare at each other, the silence between them a tangible thing. He thought, even as he had turned the car around and come back for her, that he would know exactly what to say. That he would find here, sitting here in Matanzas, and just tell her to get in the car—a Mexican Honeymoon Part II, almost.
“You want some company?” he asks, and suddenly it feels like they're covered in blood and standing outside of the Titty Twister again, a lifetime of bad decisions ahead of them.
But she smiles at him, fully and almost bright “Yeah.”
.
.
.
It's an hour and eighty miles later that Richie finally says, “Seth said we forgot you. Like we left you at a Target or something.”
And Kate laughs, quiet under the roar of the car.
Seth focuses on driving, los tres Geckoes riding off into the sunset, these precious few moments like the freeze frame end of Butch Cassidy and the Sundance Kid.
