A/N: Sorry about the wait everyone! I thought I would get this out sooner, but didn't find the time to write. Not just that, but I always think I'll wait a couple days to start the next chapter and then before I know it, so much time has passed! Hope you still enjoy anyway!

Disclaimer: I own nothing except for my OC, Katherine.

They had been in the air for about eight minutes and Dean had been freaked out for at least ten, which went against all laws of math, but somehow seemed correct.

They managed to get three seats together, Sam sitting by the window, Dean on the end, and Kat in between. It was a peaceful flight so far, aside from Dean's panic and the knowledge that a demon could crash the plane and kill them all.

Okay, maybe not that peaceful.

"—you're humming Metallica?"

Sam's confused question prompted Kat to turn her attention to Dean who was, in fact, softly humming a Metallica song.

"Calms me down." His answer was short and clipped, and it was obvious that he was so nervous that he barely even wanted to talk.

Sam scoffed, shaking his head. "Look, man, I get you're nervous, alright? But you gotta stay focused."

"Okay." How convincing.

"I mean, we got thirty-two minutes and counting to track this thing down, or whoever it's possessing, anyway, and perform a full-on exorcism."

"Yeah, on a crowded plane, that's gonna be easy."

"Just take it one step at a time, alright? Now, who is it possessing?"

"It's usually gonna be somebody with some sort of weakness, you know, a chink in the armor that the demon can worm through. Somebody with an addiction or some sort of emotional distress."

Kat nodded. "My money's on Amanda. She's on a plane after surviving a crash not that long ago, not to mention she's probably thinking about her boyfriend who she thinks wants to see her."

Sam voiced his agreement and Dean looked up at a flight attendant who was walking through the aisle. "Excuse me. Are you Amanda?"

The flight attendant smiled sweetly. "No, I'm not."

"Oh, my mistake." Dean gave her a smile as she walked off, before quickly looking into the back of the plane where another flight attendant was. "Alright, well, that's gotta be Amanda back there, so...I'll go talk to her, and I'll get a read on her mental state..." He was pressed tightly against the seat as he had been for most of the short plane ride, words and breaths coming out nervously.

"What if she's already possessed?"

"There's ways to test that." Dean reached into a bag at his feet, taking out a bottle of water that had Mary on it. "I brought holy water."

"No." Sam reached over Kat to yank it away, quickly hiding it in his jacket. "I think we can go more subtle. If she's possessed, she'll flinch at the name of God."

"Oh. Nice." Dean unbuckled his seatbelt, standing and starting towards the back of the plane, only to stop and turn back as Sam called after him. "What?"

"Say it in Latin."

"I know." He turned to go again.

"Hey!"

He rushed back, leaning down and glaring at Sam. "What?"

"Uh, in Latin, it's 'Christo'."

"Dude, I know, I'm not an idiot." He moved to go to Amanda once again, only for Kat to grab his arm. He rolled his eyes and whipped back around, giving her a look. "I know. It's Christo. I know how to say it."

"Dean." She gave him a look of her own, though hers was worried whereas his was just plain frustrated. "Do you want me to go instead?"

"What? No. I'm fine."

"You're sweating."

"I'm fine! And I'm not letting you go after a demon by yourself." He pulled away, pausing and staring at them both to make sure they had nothing else to say, before turning and walking through the aisle.

Kat watched him go, sighing as the plane shook and he stumbled, taking out his nervousness by punching a seat before he carried on.

"You okay?"

She settled back in her seat to look at Sam, smiling softly. "Yeah. I'm good." Good was better than fine. She hadn't thought of her father much at all since they figured out there would be another plane crash; she had bigger things to worry about that were at the forefront of her mind. It was likely she would be back to 'fine' once all this was dealt with, but she felt okay for now. And 'fine' really wasn't so bad compared to what she felt before anyway.

"Good." There was a beat of silence, before Sam asked with a bit of an amused smirk, "Can you believe Dean is afraid of flying?"

"It's not funny, Sam."

"Come on. You don't find it a little funny? Dean's not scared of anything."

"Sure. In fact, I'd say it's as funny as the clown sitting behind us."

Sam immediately turned his head to look at the seats behind them, his look of slight fear soon morphing into annoyance. There were just two normal people behind them: a man resting his eyes and a woman reading a book. "You're hilarious." He did sound a little relieved. Maybe because there was no clown, maybe because Kat was actually joking around like normal. Maybe both. "Watch out for the snake on the floor."

"Like I'm gonna fall for that." Despite her words, Kat carefully pulled her feet up off the floor, just in case there happened to be a snake that wanted to crawl up her leg or something. Sam noticed with a smirk, but took John's journal out of his bag instead of making a comment.

The two had shared a lot when they were younger, and fears weren't excluded. Evidently, their fears remained the same over the years.

Dean returned, dropping into his seat with a sigh. "Alright, well, she's gotta be the most well-adjusted person on the planet."

"You said 'Christo'?"

"Yeah."

"And?"

"There's no demon in her. There's no demon getting in her." He buckled his seatbelt as Sam let out a sigh.

"So, if it's on the plane, it can be anyone. Anywhere."

The plane shook and next thing Kat knew, she had Dean's crushing grip on her arm. She had dealt with pain, but this was something else entirely, and she couldn't help the slight whimper that passed through her lips. "Dean—"

"Come on! That can't be normal!"

"Hey, hey," Sam spoke softly, "it's just a little turbulence."

Dean gave his brother a look of anger and fear, lowering his voice. "Sam, this plane is going to crash, okay? So quit treating me like I'm friggin' four!"

"You need to calm down."

"Well, I'm sorry, I can't!"

"Yes, you can."

"Dude, stow the touchy-feely, self-help yoga shit. It's not helpi—"

Sam leaned over Kat so he could look Dean in the eyes. "Listen, if you're panicked, you're wide open to demonic possession, so you need to calm yourself down. Right now."

Dean hesitated, before taking in a breath and letting it out slowly, his posture starting to relax. His grip, however, did not, and the consistent pain was starting to make Kat panic, which would make her open to demonic possession.

"Dean," she said his name through a clenched jaw, grabbing onto his hand.

Sam looked down, before quickly looking up at Dean. "Dude! You're gonna break her arm. Let go. Just relax." He watched as his brother took another breath and released Kat's arm, who quickly pulled it to her body with a relieved sigh. He shook his head and turned to look at John's journal. "I found an exorcism in here that I think is gonna work. The Rituale Romanum."

Dean looked at the book almost sadly. Panic had turned to defeat, with a little guilt added in for Kat's arm. "What do we have to do?"

"It's two parts. The first part expels the demon from the victim's body. It makes it manifest, which actually makes it more powerful."

Both Kat and Dean shot Sam wide-eyed looks and the latter asked, "More powerful?"

"Yeah."

"How?"

"Well, it doesn't need to possess someone anymore. It can just wreak havoc on its own."

"I'm sorry," Kat stared at him. "This is something we want?"

"Well, yeah, 'cause the second part sends the bastard back to hell...once and for all."

Dean sat back, seeming like he was trying not to look scared, his words frustrated. "First thing's first, we gotta find it." He leaned down, searching through his bag until he pulled it his homemade EMF meter. "You guys memorize the Roman Ritual—"

"Rituale Romanum." Sam reminded him with a sigh.

"Yeah, whatever. Just memorize it while I see if I can find the son of a bitch." He got up and took a step, but briefly turned back. "You two gonna stop me to tell me a bunch of shit?" He was met with two innocent looks, so he nodded and turned away, walking to the back of the plane.

"Here." Sam set the open journal between himself and Kat, so they could both skim through the needed words. They had managed to go over it three, maybe four times, before Dean came back into view as he finished scanning down the aisle.

Both hunters got up and moved up behind him, Kat saying his name just as Sam clapped him on the shoulder. The poor guy nearly jumped out of his skin.

"Don't do that!"

Sam ignored his brother's fear and asked, "Anything?"

"No, nothing. How much time we got?"

"Fifteen minutes." Sam sighed. "Maybe we missed somebody."

Dean looked around, shaking his head. "Maybe the thing's just not on the plane."

"—you believe that?" Clearly Sam didn't, by the look he gave Dean.

"Well, I will if you will."

"I'm willing to believe it." Kat spoke lowly, fully aware of how strange it must look to the passengers for the three of them to be standing together. They'd be in for a world of police interrogating them once they landed if someone happened to hear them. "Maybe we'll just land safely, then we can have a nice vacation?" She got a look from Sam, but Dean was too busy looking down at the EMF meter. "What's wrong?"

He looked up and both she and Sam followed his line of vision, just as the copilot of the plane stepped out of the bathroom. He gave the three a smile and a nod, before moving towards the door to the cockpit, opening it just as Dean softly said, "Christo." The man paused, then turned to look over his shoulder at them with pure black eyes and a pissed off look.

Sam and Dean stared and gulped, while Kat grabbed onto their arms. Her grip was nowhere near as tight as Dean's had been before, but it was as tight as she could manage, what with fear she hadn't expected taking over her body.

"Shit. Shit. The copilot? He can take the plane down in an instant. What are we supposed to do now?"

Dean glanced at Kat, then at the door to the cockpit, then at Sam. "We should tell Amanda. We can't get to him without her."

"What makes you think she's gonna do what we want, Dean?" Sam shook his head. "We barely have enough time as it is."

Kat forced herself to calm down, knowing that fear wasn't going to help anything. Especially with a time limit, fear would only hold her back. "We have to try."

"And if it doesn't work?"

"I'm gonna break into the cockpit."

"Kat, you can't break into the cockpi—"

"Dude." It was very rare that Dean ever had to interrupt an argument between Sam and Kat, whether a light or serious one, as they didn't butt heads often. Even their little rifts when Sam joined them again had been quick, and he wasn't involved anyway. "Unless you've got some genius plan, let's go talk to Amanda."

Sam relented after a moment, turning to walk towards the back of the plane with Kat and Dean behind him. "She's not gonna believe this."

"Twelve minutes, dude," Dean reminded him as they continued to the back of the plane, where Amanda was fiddling with something.

She looked over her shoulder and smiled as she recognized Dean, but did cast a confused look at Sam and Kat. It was probably odd, having three people out of their seats and in the flight attendants' work area. "Oh, hi. Flight's not too bumpy for you, I hope."

"Actually, that's kind of what we need to talk to you about." Dean looked at Sam as he closed the curtain.

Amanda, God bless her, didn't even seem put off by the fact that she was alone with three strangers, one of which just closed the barrier between them and other people. Most people would have looked worried or tensed up in preparation for whatever could come, but she didn't even flinch. She really was the most well-adjusted person on the planet. "Um, okay. What can I do for you?"

"Alright, this is gonna sound nuts," Dean lowered his voice, "but we just don't have time for the whole 'the truth is out there' speech right now."

Sam touched his brother's arm, as a way of 'tapping in', so to speak. "Alright, look, we know you were on flight 2485."

That finally seemed to get to Amanda. Her smile fell and she took in a rather fearful breath before asking, "Who are you?"

"Not stalkers," Kat was quick to say, offering her a reassuring smile.

"Now, we talked to some of the other survivors. We know something brought down that plane and it wasn't a mechanical failure."

"We need your help, because we need to stop it from happening again. Here. Now."

Amanda furrowed her brow and averted her gaze. "I'm sorry, I—I'm very busy. I have to go back—" She tried to squeeze between Kat and Dean, only for the latter to grab her by the shoulders.

"Whoa, whoa, whoa, whoa, wait a second."

"I have to go ba—" Her words halted with a gasp as he pushed her back, and she was beginning to look a bit fearful.

"I'm not gonna hurt you, okay? But—"

"Chuck Lambert is dead." Kat's words were quick and blunt, but her tone was soft. She spoke in such words not to push Amanda or get things over with, but rather to keep the situation from getting worse. While she knew Sam and Dean were harmless, Amanda was more than likely starting to feel threatened, and the last thing they needed was her screaming and the Winchesters ending up tackled by passengers. She didn't want the poor woman to be scared of them anyway; it wouldn't be fair to her. "The pilot from flight 2485. He died in a plane crash."

"Wait, what?" Amanda's tone was full of shock and upset. "What— Chuck is dead?"

"That's two plane crashes in two months. That doesn't strike you as strange?" Dean's words were just as blunt as Kat's, but not as gentle. She couldn't blame him. They probably had about ten minutes to go.

"Not just two plane crashes." Kat gave Amanda the most meaningful look she could. "But also with the same guy. That doesn't just happen."

"Look, there was something wrong with 2485. Now maybe you sensed it, maybe you didn't. But there's something wrong with this flight, too."

"Amanda, you have to believe us."

"We're telling the truth. We may sound crazy, but we're not messing around here."

Sam's convincing words, Dean's urgent tone, and Kat's reassurance seemed to finally get through to her. She stared at them, then looked away, hesitating and rubbing her forehead in distress, before saying, "On 2485, there was this, uh, this man, he...had these eyes."

"Yes!" Sam almost sounded excited. "That's exactly what we're talking about."

"I don't understand. What are you asking me to do?"

"Okay. The copilot, we need you to bring him back here."

She seemed unconvinced again. "Why? What does he have to do with anything?"

"Don't have time to explain, we just need to talk to him, okay?" Dean's answer was bullshit, but it probably wouldn't go down well if he said they needed to exorcise him.

"Well, how am I supposed to go into the cockpit and get the copilo—"

"Whatever it takes." Sam was becoming as urgent as Dean now, realizing that they were so close and the seconds were ticking by. "Do whatever it takes. Tell him there's something broken back here, whatever will get him out of that cockpit."

"Do you know that I could lose my job if—"

"Okay, well, you're gonna lose a lot more if you don't help us out."

Seeing her hesitation, Kat intervened. "Please. If we don't do what we need to do, this is going to end up like flight 2485 and Chuck's plane." Her words combined with three earnest stares did the trick.

"Okay." She moved past them and opened the curtain, walking through the aisle to the front of the plane, where she knocked on the door to the cockpit as Sam, Dean, and Kat watched.

"What if he doesn't come over here?" Kat eyed the copilot nervously when he stepped out to talk to Amanda.

"Then I guess you can break into the cockpit." Sam's whisper was begrudging and humorless, which was fine. The knowledge that all could fail and the plane could crash wiped out Kat's humor more than everything with her father did.

After a moment, the copilot turned to speak to the pilot and then followed Amanda to the back of the plane. The three quickly moved away from the curtain, Sam taking out holy water while Dean took out John's journal and handed it to him, before pulling out some duct tape.

"Now what's the problem?" The copilot had just stepped through the curtain when Dean hit him hard, sending him stumbling into the emergency exit. He wasted no time in grabbing him and slamming him to the floor, pinning him down as he put a strip of duct tape over the guy's mouth.

Sam moved to their left, Kat moved to their right, and Amanda quickly approached them with a gasp. "Wait, what are you doing? You said you were just gonna talk to him!"

"We are gonna talk to him!" Dean continued to hold him down while Sam splashed holy water on him, making his skin burn and sizzle as he struggled.

"Oh my God. What's wrong with him?"

"Look." Sam looked up at Amanda. "We need you calm. We need you outside the curtain."

"No, wait, I don't understa— I...I..." She was running her hands over her face and her hair, looking at the man in complete fear, so Kat quickly moved to her.

"You need to wait outside, okay?" She put one hand on Amanda's back and the other on her arm, gently — but urgently, because time was flying by — guiding her to the curtain. "You need to make sure that nobody comes in." The woman was pretty stuck on the man being burned by water. "Okay?"

She nodded after a moment. "Okay. Okay!" She opened the curtains, rushing out just to get away from the terrifying scene.

Kat returned to the opposite side of Sam by Dean and the demon, while the older Winchester punched him to keep him down. "Hurry up, Sam, I don't know how much longer I can hold him."

Sam splashed more holy water on him, then turned to the journal, brow furrowed. "Regna terrae, cantate Deo, psallite Domino..."

He continued to read the ritual aloud, until the demon got its arms free from Dean's grasp and hit the holy water out of Sam's hand. He shoved Dean away before turning and hitting Sam so he fell back. Kat moved to pin the demon down again, but Dean was back on him in a second and Sam kept on with the ritual. All she could do was watch nervously.

Until the demon shoved Dean back again, and she moved to grab him, only for him to backhand her hard, sending her flying back. She groaned as the side of her head hit the wall, trying to get back up, only to find herself dizzy.

The demon had ripped off the duct tape and pulled Sam close, mocking him, "I know what happened to your girlfriend! She must have died screaming! Even now, she's burning!" He released Sam and looked over at Kat with a grin, who was struggling to her feet. "So's Daddy, we all know him down there. About time you figured it out, you bi—" Dean, filled with a new anger for both Sam and Kat, jumped on top of him and hit him again.

He wasn't the only one who was angry. Kat had felt sad, upset, confused, betrayed, but she had yet to feel truly angry over what her father had done; but now she felt it. The demon talking about her father in hell, that his evil deed made him well-known, sparked something inside of her. It was something she considered, but hoped not to be true. He could have been lying for all she knew. Could her father even be in hell? He had turned into a monster before he was killed. Did monsters go to hell? Did it even count since her father had spent all his life as a human before that? She didn't know. She didn't care. All she knew was that her head hurt, they only had a handful of minutes before the plane was supposed to crash, and the demon's words stung.

Sam was angry, too, as he looked at the demon in a daze of despair and hate. Kat stood fully and reached over Dean and the demon to take the book from him, immediately starting to read where she was sure he left off. There was hardly a line left before Sam, out of his daze, called out, "That's it!" He knelt down and helped Dean pin the demon, while Kat dropped the journal and backed away. They barely noticed that the journal was kicked out of the room and down the aisle, all too busy staring at the man as a black substance that must have been the demon fled from his mouth and disappeared into a vent.

"Where'd it go?" It wasn't clear whether Sam meant the demon or the journal.

"Into the plane. We gotta finish it."

Sam nodded and stumbled through the curtain, just as the plane suddenly careened and lighting began flashing rapidly in the sky. Passengers were screaming, Dean stumbled back, Kat fell to the floor, and Sam struggled through the aisle to get the book. Dean tried to help Sam and Kat tried to get up, but the plane started to nosedive, so the former was thrown back against the wall and the new angle had the latter sliding across the floor.

Kat hit the wall much more gently than when the demon had hit her, and was vaguely aware of Dean screaming beside her.

So that was it, then. All they had dealt with, and they were going to die in a plane crash. Sure, it was caused by a demon, but still. It seemed very mundane.

Just as she accepted this, the plane leveled out and all commotion stopped. Sam had found the journal and finished the ritual.

Kat let out quite possibly the heaviest sigh of relief and looked to her side to see a very terrified Dean. "It's okay, Dean. We made it."

"Uh-huh." He nodded stiffly, starting to stand. Kat stood with him to help him, only for her own legs to nearly give out, and the two ended up grabbing onto each other; Dean quickly put an arm around Kat's shoulders to keep from passing out from the previous events, while she put an arm around his middle to keep from passing out from her hit to the head. They walked carefully to the curtain, looking out to see Sam standing there. He looked back at them and all three had a look that seemed to convey both relief and a shared sentiment of why-does-this-shit-happen-to-us.

After that mishap, the plane obviously returned to its first destination and let all the passengers off. Paramedics came to help the now-injured copilot and police came to question people on what happened. They were questioning Amanda while Sam, Dean, and Kat stood by. She looked over at them while she wrapped up with the officer, mouthing an incredibly sincere 'thank you'.

They nodded to her, then Dean turned and sighed, "Let's get out of here." Sam and Kat followed him silently as they moved to leave the airport, and he was quick to notice Sam's solemn look. "You okay?"

He didn't answer at first, but soon stopped and turned so Dean and Kat were forced to stop in front of him. "Dean, it...it knew about Jessica."

"Sam, these things, they...they read minds. They lie. Alright? That's all it was."

"Yeah."

Dean sounded so right, yet Kat couldn't help her own fears at what the demon said about her father. She was absorbed in her thoughts for the first time in what felt like forever — it had only been a few hours since she last fell into the rabbit hole that was the entire situation with her dad, really — so she unknowingly stayed with an equally-deeply-thinking Sam as Dean carried on to the exit.

"Hey." Sam was pulled out of his own thoughts and pulled Kat right out of hers as he looked at her with concern, brow furrowed. "You're bleeding."

She focused on the slightly throbbing pain she felt, on the side of her forehead just next to her right temple, and reached up, flinching as she touched the wound there. She pulled her hand away to see fresh blood on her fingers. "I guess I am. It's not so bad."

He gave her an unconvinced look, but nodded towards the exit anyway, walking with her out of the airport. Dean was already by the Impala, waiting impatiently.

"About time. What were you two doing? Hugging?" He chuckled. Even after a barely touchy-feely moment, like comforting Sam, he had to go back to his usual self with a bit extra to make up for it. Sam just rolled his eyes and got into the passenger's side while Kat moved to a back door.

"—Dean." Her voice came out much smaller than she intended, and the tone alone had Dean pausing with his hand on the driver side door's handle and looking at her with veiled worry on his face. "Do you think the demon really was lying? Do...you think my dad's in hell?"

She wasn't sure why it mattered. Her father had done something wrong and kept it a secret for his entire life. It made her upset and hurt her beyond belief. Wasn't hell where he belonged? She supposed it was, yet for some reason, her heart refused to allow it. No matter how hurt she was, he was still her father. She still loved him. She still missed him. Was this what it took to realize it? The thought of him being damned, and not just damned, but well-known among the demons and whatever else was down there.

"Honestly, Kat? I don't know." He sighed. "Look, just...don't worry about it. He was just trying to freak you out and throw you off. I'm pretty sure it's their MO." He was met with a nod, and stared at her. "You're bleeding."

"Yeah, I know, Sam told me."

"I'll take a look at it when we're back at the motel."

"Dean, I'm fine." She received a harsh looked and sighed, nodding. "Okay." She owed it to him, since she kept him pretty closed off from the stuff about her dad. The least she could do was let him make sure her wound wasn't completely dire.

They met up with Jerry the next day, waiting by the Impala on the airport tarmac.

"Nobody know what you guys did, but I do. A lot of people could've been killed." He reached out to shake Sam's hand. "Your dad's gonna be real proud." He then shook Dean's hand and, lastly, Kat's.

She leaned against the car with Dean, two butterfly bandages over the small cut on her forehead that she'd received during the flight. He had come to her motel room the night before with first aid supplies, making her sit down as he carefully cleaned her wound with a soapy washcloth — it stung, and she winced, and he muttered out the word 'baby' with an amused smirk on his lips; the moment felt normal — and bandaged her up. He left her with some extra bandages, bid her goodnight, and left the room.

He didn't push her about her father, though he never had. He wasn't the type to ask to hear people's feelings, but more the type to complain to his brother about her lack of venting to him, like she was prone to do. He was more the type to get frustrated and concerned, and hope things returned to normal. She didn't know if he actually wanted her to open up, or wanted the Kat that he knew back; the one who was open even if Dean grumbled about it. Probably the latter.

"We'll see you around, Jerry," Sam said, as Jerry started to walk off. He paused and turned back around when Dean called after him.

"Yeah?"

"I meant to ask you," Dean moved around to the driver's side of the car. "How did you get my cellphone number anyway? I've only had it for like six months."

"Your dad gave it to me."

All three hunters paused, Sam turning to face Jerry slowly. "What?"

"When did you talk to him?"

"I mean, I didn't exactly talk to him, but, uh, called his number, his voice message said to give you a call. Thanks again, guys." He nodded to them, before walking off.

They let the information sink in, then got into the car. Dean moved it from the tarmac to the entrance of the airport parking lot. They got back out, the brothers sitting on the trunk while Kat stood by, waiting in case they needed her support.

"This doesn't make any sense, man. I've called Dad's number, like, fifty times. It's been out of service." As Sam spoke, Dean had dialed their dad's number.

A message immediately started playing and he quickly leaned over to let Sam hear. "This is John Winchester. I can't be reached. If this is an emergency, call my son, Dean. 785-555-0179. He can help."

Dean snapped the phone shut. Sam clenched his jaw, bouncing his leg for a moment, before getting up quickly and moving to the passenger side door.

Kat saw his teary, angry eyes and reached out to touch his arm, but he just ignored her and got into the car. She met Dean's eyes over the hood over the car as he went to get in, briefly met with a pained expression before he simply shook his head and slid into the car.

Everything was just buckets of fun, wasn't it?

A/N: Aw, they think they're sad now :) Probably not the most exciting chapter, but we're slowly getting into it! Sorry if there are any mistakes, and I hope you all enjoyed. If you would be so kind as to favorite, follow, and review, that would be lovely!
