Are you still itching?" Dean queried, watching as Katie scratched at the back of her head.

"You don't feel itchy after seeing that girl who had scratched her brains out?" Katie retorted, trying to restrain herself from scratching her nose.

They had arrived in the strange town the day before, where childhood myths seemed to be coming true. A teenager had put itching powder on his babysitter's hairbrush and only a few hours later, the girl had itched herself to death. Ever since then the weird occurrences had been coming quickly.

"Not really" Dean shrugged.

"Right, I forgot I'm talking to the guy who's eating ham he cooked with a joy buzzer" Katie rolled her eyes, as she watched Dean take a bite of his ham sandwich.

"We don't have a fridge" Dean murmured.

"You know that ham is probably cursed right?" Katie pointed out, as Dean slowly put the sandwich back down, with concern on his face.

"Actually, if our latest theory is right, it's probably not" Sam announced, looking up from the map he had splayed out on the kitchen table.

"So, this ham probably won't kill me?" Dean questioned, taking a bite out of the sandwich as his brother nodded.

"What's this new theory then?" Katie inquired.

"Whatever is doing this is reshaping reality. And has the humour of a nine-year-old" Sam stated.

"Sounds like you," Katie told Dean, who rolled his eyes, enjoying his sandwich too much to reply.

"Or a Trickster" Sam suggested, as Katie's eyes widened.

"I don't know…what would be the point? There doesn't seem to be anything special about this town" Katie pointed out.

"Since when did that dick need a reason? Maybe he found out the Apocalypse was on and wanted to blow a little steam" Dean went on.

"That doesn't really sound like him…I mean, from what you guys have told me…" Katie trailed off, awkwardly.

Why can't one of my demon powers be the ability to lie well, Katie thought to herself. It was strange how her impression of the Trickster was so different to the Winchester's. Was it possible the man had just changed since the last time he met them? It seemed unlikely. Maybe he was just a better liar than she was.

"Well whatever is doing this, I might have found them. All the weird occurrences that have happened have been within a two-mile radius" Sam explained, showing them the area, he had outlined on the map.

"So, we've got a blast zone of weird and inside fantasy becomes reality" Dean exclaimed.

"Looks like" Sam nodded.

"And what's the A-bomb in the centre?" Dean asked, coming to stand beside them.

"Four acres of farmland…and a house" Sam replied.

"Huh, well that was easy. Sounds like it's time for a house visit" Katie announced, as Sam nodded.

"Our motel isn't in that circle, by any chance?" Dean queried.

"Yeah…why?" Sam frowned, as Dean held up his hand which was now thick with hair.

"Jesus, Dean. I'm gonna' throw up" Katie grimaced.

"Oh, dude…" Sam trailed off in disgust.

"I got bored" Dean shrugged, as Katie made gagging noises.

"You know you can go blind from that too," Sam told him.

"Give me five minutes and then we'll go check out that house" Dean exclaimed, as he walked towards the bathroom.

"Hey, do not use my razor!" Sam warned him, making Katie chuckle lightly.

"You know your razor's in there too, right?" Sam retorted, raising an eyebrow at her.

"Dean!" Katie shouted, as Dean rushed into the bathroom and locked the door.

"I swear to God, Dean Winchester, if I find even a strand of hair in my razor, I'll drag you to hell myself!" Katie screeched, banging on the door.

Stepping out of the Impala, Katie looked around their surroundings, finding the house in front of them to feel oddly foreboding. It was as if she could see the house pulsing with energy.

"Hey, what's wrong?" Sam questioned, placing his hand on her shoulder.

"This is definitely the right house" Katie murmured, as they began walking towards the structure.

"Your demon senses tingling?" Dean suggested as they neared the porch.

"More like quivering" Katie admitted, watching Sam take out his lock-picking kit.

"What are you doing?" She frowned.

"Getting us a way in" Sam retorted as if it was obvious.

"There's this crazy invention, Sammy. It's called a doorbell. How about we use it?" Katie rolled her eyes, pressing the bell.

A few seconds later the door was opened by a small boy, who could have been no older than eleven. Katie almost felt dizzy from the power that seemed to radiate off the child.

"Can I help you?" He questioned.

"Hi, uh…what's your name?" Sam inquired, seeming a little taken aback from a child answering the door.

"Who wants to know?" The child asked, making Katie chuckle.

"We're FBI" Katie announced, as the three took their badges out.

"Let me see that" The child exclaimed, grabbing Katie's badge and taking a closer look.

"You don't look twenty-four" The boy stated, giving Katie a look as he returned her badge.

She had always been nervous about upping her age for their fake badges, but no one would believe someone of her age could be an FBI agent. She wasn't surprised the boy was the first person to pick up on it.

"I just have one of those faces…uh, are your parents' home?" Katie inquired, looking around the house.

"They work" The boy shrugged.

"Well, you mind if we ask you a few questions, maybe take a look around the house?" Sam inquired.

"I don't know" The child murmured, unsurely.

"C'mon, you can trust us. We're the authorities" Dean insisted, waving his badge around.

"Does that work with most people?" The boy retorted, crossing his small arms.

"We've got McDonald's in the car…we'll split it with you?" Katie offered.

"I'll take all of it and you've got a deal" The kid replied, making Katie grin.

"I like him" She laughed.

"What's that?" Sam questioned, as they walked into the kitchen, and saw some soup boiling on the stove.

"It's called soup. You heat it up and you eat it" Jesse told him, sarcastically, as Sam chuckled.

"Right. I know. It's just, um...I used to make my own dinner, too, when I was a kid" Sam admitted, as Katie walked in with a bag from McDonald's in tow.

"Well, I'm not a kid" Jesse scoffed, making a beeline for the food.

"That told you" Katie smirked, as she gave the boy a bag of fries.

"I'm Katie, by the way" She informed the boy, holding out her hand for him to shake.

"Jesse" The boy replied, shaking her hand.

"Nice to meet you" Katie smiled, as Dean took a step forward.

"What do you know about itching powder, Jesse?" Dean inquired.

"That stuff will make you scratch your brains out" Jesse exclaimed, as Dean took the joy buzzer out of his pocket that had recently been involved in the strange occurrences in town.

"You shouldn't have that" Jesse warned him, his eyes wide.

"Why not?" Dean inquired.

"It can electrocute you" Jesse insisted.

"Actually, it can't. It's just a wind-up toy. It's totally harmless. Doesn't even have batteries" Dean explained.

"So it can't shock you?" Jesse frowned.

"Nope. Not at all. I swear" Dean promised.

"Oh. Okay" Jesse murmured.

"I mean, all it does is just shake in your hand. It's kind of lame. See?" Dean went on, as he pressed the joy buzzer against Sam's chest, who jumped in shock.

Sam gave his brother a murderous look, as Katie had to bite her lip to stop herself from laughing at his expression. The boy was clearly involved in what was going on, there was no doubt about it. After a few more minutes the boys decided they needed to find out more about the kid and went to leave.

"I'm going to stay with Jesse for a bit longer" Katie announced, making the brother's frown.

"What, why?" Dean inquired.

"He could be in danger. What happens if word gets out how much power this kid has?" Katie pointed out.

"Katie, he's the one we need protection from. You've seen what he's done in this town!" Dean insisted, in a hushed whisper.

"I don't even think he knows he's doing it" Katie stated.

"He's unpredictable" Sam sighed, as he knew they weren't going to be able to change her mind.

"Then he needs a babysitter. I've got this, okay? Find out what you can, and we'll regroup later" Katie told them.

"…Don't do anything stupid" Dean warned her, with a huff, obviously not happy about leaving her there.

"Be careful" Sam exclaimed, as he reluctantly turned to leave.

"When do your parents usually get home, Jesse?" Katie queried, as she wandered back into the kitchen where Jesse had almost finished the McDonalds food.

"Few hours maybe?" Jesse shrugged, eating the last remnants of his burger.

"They leave you anything more to eat than soup?" Katie asked.

"…They'll bring more food home tonight" Jesse insisted.

"Right…unless they forget. Which let me guess, they do a lot?" Katie suggested, sitting down at the dining room table.

"You don't know them" Jesse grumbled.

"No. But I know parents like them. I had a couple like them myself…" Katie trailed off, watching as Jesse frowned.

"I grew up in care. I learned the hard way how disappointing parents can be" Katie admitted.

"They love me" Jesse shook his head.

"I never said they didn't" Katie pointed out.

"They could be a lot worse" Jesse mumbled, fidgeting with his hands.

"That doesn't make it hurt any less when they leave you on your own all day" Katie stated, seeing how tears had begun to well in Jesse's eyes.

Katie's eyes widened as the lights in the room began to flicker, and she could feel the ground beneath them rumble. Jesse seemed to be even stronger than she realised.

"It's not fair" Jesse exclaimed, balling his hands into fists.

"Jesse, calm down…" Katie trailed off, as the wall behind them split down the middle with a large bang.

"What's…what's happening?" Jesse panicked, as a lamp near them exploded, making the boy flinch.

"Jesse, I need you to breathe, okay? Look at me. You're okay. Everything's okay" Katie soothed, as she placed her hands on his shoulders.

"I…did I do that?" Jesse realised, his eyes landing on the crack in the wall.

"We're going to figure out what's going on with you, Jesse. I promise" Katie insisted.

"Wait…those weird deaths that have happened…was that me?" Jesse gaped; his eyes wide with fear.

"It's not your fault. You have more power than you can handle-" Katie began, but Jesse cut her off.

"I killed them…I'm…I'm a killer…" Jesse stuttered as the remaining lights flickered once again.

"You didn't know, okay? What you do from now on, that's what matters, Jesse. I'll help you" Katie told him.

"How can you help?" Jesse questioned, shrugging her off him.

"Because…I'm not exactly normal either" Katie confessed, raising her hand out and using her telekinesis to cause the can of soup to fly into her hand.

"What…what are you?" Jesse gasped.

"I'm here to help. Will you let me help you, Jesse?" Katie asked, as the boy slowly nodded.

"I don't want to be like this. I'm a freak" Jesse sobbed, tears beginning to roll down his cheeks.

"You're not a freak. You're just different. And there's nothing wrong with that" Katie insisted, as she crouched down and pulled the shaking boy into a tight hug.

Katie reluctantly left Jesse a few hours later, knowing his parents would be coming home soon, and it would be too difficult to explain what she was doing there. She had managed to cheer him up after his outburst, with the help of some cartoons. She felt strangely connected to Jesse. He had immense power thrust upon him that he didn't want and now he was messed up in the Apocalypse. The parallels were too clear to miss. She decided to use her power to teleport back to the motel room rather than calling for the Winchester's to pick her up. She was desperate to know what they had found out about the boy. The surprise was clear on her face when she appeared in the motel room to find Castiel was there. She was even more confused when she saw how his shoulders sagged in relief when he saw her.

"Katie, are you alright?" Castiel asked, taking a step closer to her.

"Uh, yeah…why wouldn't I be?" Katie frowned, looking to Sam and Dean who shared Castiel's relieved expression.

"The boy is far more dangerous than you could ever imagine. We were concerned you had been hurt" Castiel explained.

"We?" Katie questioned, with a small smirk on her face.

"Cas was all but ready to burst into Jesse's house and save you" Dean teased, as Castiel turned to glare at him.

"Save me from what? Jesse?" Katie queried, watching Castiel nod.

"What are we gonna' do with the kid?" Dean inquired, leaning against a nearby set of drawers.

"Kill him" Castiel answered, as Katie's jaw dropped.

"What?" Katie gaped, unable to believe what the angel had just said.

"This child is half demon and half-human, but it's far more powerful than either-" Castiel began, but Katie cut him off.

"Wait, what?! Jesse's half-demon?" Katie gasped.

"His mother was possessed by a demon. Jesse's father. It's on a whole other level of messed up" Dean informed her.

"Jesus, and I thought my past was screwed up" Katie mumbled.

"Other cultures call this hybrid cambion or katako. You know him as the antichrist" Castiel announced, as he went to sit down, as a loud fart noise erupted from his chair.

The sound went on for over ten seconds, as Katie raised an eyebrow at Dean, knowing he must have been the one to put it there. If the situation wasn't so serious she would have been in a fit of laughter from the awkward look on Castiel's face.

"That wasn't me" Castiel exclaimed, pulling out the whoopee cushion from underneath him.

"Who put that there?" Dean grinned, causing Castiel to give him a murderous look.

"Anyway, I don't get it. Jesse is the devil's son?" Sam questioned.

"No, of course not. Your Bible gets more wrong than it does right. The antichrist is not Lucifer's child. It's just demon spawn. But it is one of the devil's greatest weapons in the war against heaven" Castiel sighed.

"He's just a kid" Katie insisted.

"What the hell's he doing in Nebraska anyway?" Dean frowned.

"The demons lost him. They can't find him. But they're looking" Castiel warned.

"And they lost him because?" Dean inquired.

"Because of the child's power. It hides him from both angels and demons. For now" Castiel went on.

"So he's got, like, a force field around him. Well, that's great. Problem solved" Dean stated.

"Not quite. I've been able to sense Jesse's power ever since we came to town. His house is practically pulsing with energy. There's a bullseye target on his front door" Katie sighed.

"With Lucifer risen, this child grows strong. Soon, he will do more than just make a few toys come to life—something that will draw the demons to him. The demons will find this child. Lucifer will twist this boy to his purpose. And then, with a word, this child will destroy the Host of Heaven" Castiel announced.

"Whoa, whoa. Wait. You're saying that—that Jesse's gonna nuke the angels?" Dean realised.

"We cannot allow that to happen," Castiel told them, as Katie scoffed.

"You can't just kill him! This is crazy! Guys, back me up here" Katie insisted, turning to the Winchester's.

"We're the good guys. We don't just…kill children" Sam pointed out.

"A year ago, you would have done whatever it took to win this war" Castiel retorted.

"Things change" Sam shot back, as Katie put herself in between the pair.

"Cas, think about what you're saying. He didn't even know what he was doing" Katie went on, as Castiel's eyes widened.

"Didn't know? You told him?" Castiel gaped, watching Katie reluctantly nod.

"He figured it out for himself. He knows he's the cause of the deaths in town. He feels guilty" Katie stated.

"For now. Once Lucifer has his hands on him-" Castiel started, but Katie cut him off.

"We won't let him! We need to protect Jesse, not hurt him" Katie insisted, as everyone was surprised by how much she seemed to care about the child.

"Okay. Hey, look, we are not going to kill him. All right? But we can't leave Jesse here either. We know that. So...we take him to Bobby's. He'll know what to do" Dean suggested.

"You'll kidnap him? What is going on in this town, it's what happens when this thing is happy. You cannot imagine what it will do if it's angry" Castiel pointed out.

"He's not a thing. He's a person. He's still half-human" Katie sighed.

"Well, how will you hold him? With a thought, he could be halfway around the world" Castiel exclaimed, knowing he wasn't getting anywhere.

"So we tell him the truth" Katie replied, as Castiel's eyes widened.

"You say Jesse's destined to go dark side—fine. But he hasn't yet. So if we lay it all out for him—what he is, the apocalypse, everything…he might make the right choice" Sam added, wanting to back Katie up.

There was a long pause then, as Castiel seemed to rile himself up for his reply. Katie was shocked when he finally spoke.

"You didn't" Castiel spat out, making Sam glare back at him.

"That's enough! Sam's right and you know it. Please Cas. Don't do this" Katie begged, taking a step forward so that she was standing only inches away from him.

"I can't take the chance that Jesse will choose the wrong side," Castiel told her, looking away from her pleading eyes.

"If you lay a hand on him, I swear to God, Castiel, I'll-" Katie began, but Castiel cut her off this time.

"You'll what? Hurt me? Kill me?" Castiel retorted, meeting her eyes finally.

"I'll never forgive you for this" Katie warned him, watching as Castiel flinched.

"…I'm sorry" Castiel mumbled, as he disappeared with a flutter of his wings.

"Damnit" Katie cried, as she tried to use her powers to pull him back.

"Can you bring him back here?" Dean asked, seeing the concentration on her face, as she closed her eyes.

"He's blocking me" Katie shook her head.

"You could bring him back before" Sam pointed out.

"He wasn't trying to stop me before. Follow me as quickly as you can" Katie announced, as Sam realised what she was going to do.

"Katie, wait!" He exclaimed, groaning as she suddenly disappeared.

"They have seriously got to stop doing that" Dean grumbled, as the pair rushed out of the door.

Meanwhile, Katie had managed to teleport back to Jesse's house, and began to search the home for the boy. It didn't take her long as she found him backed up against a nearby wall, fear written across his face.

"Jesse, are you okay?" Katie inquired, as he nodded slowly.

"Was there a guy here? Wearing a trench-coat?" Katie asked, watching Jesse point to the ground.

She felt her heart drop when she saw there was a figure now on the ground and crouched down to get a closer look at it. It looked exactly like Cas. With a nervous gulp, she realised it was the Angel. How the hell did Jesse manage to turn such a powerful entity into an action figure?

"Can…can you change him back?" Katie queried, picking up the figure.

"He tried to kill me" Jesse retorted.

"He…he was just confused…" Katie trailed off, knowing how bad the excuse sounded.

"He was confused about trying to stab me with a knife?" Jesse pointed out, raising an eyebrow.

"He's scared. People do stupid things when they're scared. He's not a bad guy, I swear" Katie insisted.

"He'll just try to hurt me again if I bring him back" Jesse stated.

"I won't let him," Katie told him, as she went to place the Castiel figure above the fireplace.

"He's your friend?" Jesse frowned, watching the care Katie took when she placed him down.

"I'd like to think so but…" Katie sighed.

"Either he's your friend or he's not" Jesse pointed out, confused by Katie's answer.

"I care about him. But I'm not so sure how he feels about me" Katie mumbled.

"Adults make everything so complicated" Jesse grumbled, as Katie chuckled lightly.

Author's Notes: I hope you all enjoyed this chapter! I really liked Jesse's character arc and I'm still hoping he might return in the last season. Lots of angst in this chapter with Katie/Cas that I liked too, haha. Please leave a review:)
