Sam and Dean had a problem. They found a Cambion in Alliance, Nebraska. They have never dealt with an Anti-Christ before. They didn't know what to do. Luckily Castiel showed up in their motel room.

"It's lucky you found the boy." Castiel said.

"Oh yeah, real lucky." Dean replied sarcastically. "So, what do we do with him?"

"Kill him." Castiel answered simply. Sam froze in the middle of tying his tie. Both brothers stared at Castiel, who stared back.

"Cas." Dean said imploringly.

"This child is half demon and half human, but it's far more powerful than either. Other cultures call this hybrid cambion or katako. You know him as the antichrist." Castiel explained. He sat on a chair which made farting noises. Confused, he shifted positions and the noises continued. Dean watches in amusement, raising his eyebrows.

"That wasn't me." Castiel said innocently. He pulls out a whoopee cushion.

"Who put that there?" Dean joked.

Sam jumped in, getting back on topic. "Anyway, I don't get it. Jesse is the devil's son?"

Castiel sighed. "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."

"Well, if Jesse's a demonic howitzer, then what the hell's he doing in Nebraska?" Dean wanted to know.

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

Dean slowly shook his head. "And they lost him because?"

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

"So he's got, like, a force field around him. Well, that's great. Problem solved." Dean smiled and threw out his arms.

"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 went on. Why is Dean not understanding the situation here?

It was like a light switched on in Dean's head. "Whoa, whoa, whoa, whoa. Wait. You're saying that—that Jesse's gonna nuke the angels?"

"We cannot allow that to happen." Castiel said with determination.

Sam stands up. "Wait. We're the good guys. We—we don't just—kill children."

Castiel's patience was wearing thin. "A year ago, you would have done whatever it took to win this war."

"Things change." Sam argued.

Dean stepped forward, putting a hand on Sam's arm and putting himself between Sam and Caastiel. "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."

"Cas, you have a Nephilim for a son. How is that any different than Jesse being a half-demon?" Sam asked.

"It's different, because Blaine didn't choose this life." Castiel responded, glaring at Sam.

"Neither did Jesse!" Sam exclaimed, throwing his arms out.

"No matter what people and angels may think about Nephilims, Cambions are much worse."

"So we take Jesse to Bobby's." Dean repeated firmly.

Castiel just stared at his friend in dismay. "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. Besides, how will you hold him? With a thought, he could be halfway around the world."

"So we-"

"So we tell him the truth. 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 said, interrupting Dean.

There was a long pause before Castiel spoke. "You didn't. And I can't take that chance."

Sam glared after Castiel as he vanishes, then he sighed in frustration. "Damn it." There was no way to talk Castiel out of this. Unless… "Dean…I know you don't like this, but…what if we tell Blaine what's going on?"

"Sam…" Dean shook his head warningly.

"He kind of understands what Jesse would be going through if we tell him everything, and he could convince Cas-" Sam went on.

"Sam, no!" Dean said sternly. "I made myself very clear: I do not want Blaine involved in this shit!"

"Well, what other choice do we have?" Sam shrugged.

"We can stop Cas on our own!" Dean fired back. "Sam…we are not going to involve my son. Okay?"

Sam sighed and nodded. "Okay."

"Good." Dean exhaled sharply. "Now, I'm going to get some grub and gas up Baby. Then we're gonna figure out a way to convince Cas that we can train Jesse to be good."

"Okay. I'll call Bobby and look up some information about Cambions." Sam replied.

Dean nodded. "All right."

Sam waited until Dean left before opening up his laptop and looking up the closest airport to Blaine's house.

Blaine's first few weeks of school was hectic. He managed to go three days without getting lost and was determined to continue this streak. He was finishing up his homework when his phone rang. "Uncle Sam, this is a surprise."

"Yeah, hi." Sam cleared his throat. "Listen, uh, we have kind of a weird situation here."

"Weirder than normal?" Blaine raised an eyebrow.

"Haha. We found a Cambion- half-demon, half-human- child in Alliance, Nebraska." Sam explained. "Your dad- Castiel- wants to kill him."

"What?! Why?!" Blaine exclaimed. "He's just a kid!"

"I know."

"So, how are you going to stop him?" Blaine asked. Then he realized… "That's why you called me. To convince Castiel to back off."

"Yeah."

"Okay, no problem. I'll call upon him, and-"

"The thing is…I don't think Castiel will come when you call." Sam replied. "At least not right away."

"Okay, then once you find him, you can call me."

"It may be too late."

Blaine huffed and threw out his free hand. "Then I don't know how you expect me to talk him down."

"I'm emailing you a plane ticket to Alliance." Sam explained. "I will also text you the address to Jesse's- the Cambion's- house so you can take a cab straight there."

Blaine stopped in surprise. "Uncle Sam, the nearest airport is forty-five minutes away, and I have school in the morning!"

"Well, this is an emergency." Sam insisted.

"Okay. Got my boarding pass. I'll see you in a few hours." Blaine replied. He hung up, quickly packed and rushed out of his room. He found a note from Ellen, explaining that she and Jo went to Toledo to visit distant relatives. He left a note for Ellen in return, that he left for Alliance to help his dad, and he'll be back by morning. His own car was still in the shop. He sighed in irritation. He didn't want to do this, but, he had no other option. He called Kurt.

"Why, hello, Blaine Anderson." Kurt replied, pleasantly surprised.

"Hey, Kurt. Um, listen, I know this is kind of weird and last minute, but I really need to get to the airport now, and my car is in the shop." Blaine said in one breath.

Kurt was now really surprised. "Oh. Okay. I can be at your house in ten minutes."

"Thanks!" Blaine replied. "See you in ten."

"So…your aunt and cousin are visiting relatives, so you're going to talk your dad out of something in Nebraska of all places." Kurt recounted.

"That sums it up." Blaine replied, shrugging.

"Okay…why are your dads in Nebraska?" Kurt asked. Kurt was surprised to learn that Blaine had two dads. Blaine explained that his real mom and real dad were married, but they got divorced, his mom remarried, so he really has an adopted dad, his real dad, and his stepdad. ("Wow- Father's Day must be really overwhelming for you." "Actually, my adopted dad gave me back to my real parents, so I only have two dads to give Father's Day gifts to.").

Blaine let out a long sigh. He didn't want to lie, but, he had to keep it a secret. "His job."

"Oh." Kurt nodded. "Okay, none of my business. Do you have someone to pick you up from the airport there?"

"My uncle arranged for a cab to pick me up." Blaine explained. "I didn't want to pay for a cab going all the way out to the airport here, so, that's why I called you."

"Oh. Hmm. Good thing I didn't-" Kurt caught himself. "I-I mean, good thing I answered my phone."

Blaine noticed that near-miss. What was he going to say? He just nodded. "Yeah. Thanks. I don't know what I would have done if you didn't."

Kurt laughed softly. They neared the airport now. Kurt parked near the entrance. Blaine rushed out of the car. "Good luck!"

"Thanks!" Blaine called back. He went through security and got to his gate easily. Once on the plane, he sighed and pulled out his phone to turn it off. It rang. "Hey, Aunt Ellen. Did you see my note?"

"I did. Does your father know you're going to them?" Ellen asked.

Blaine hesitated. "Um, no, but my uncle does. I'm sure he'll tell Dean."

"How'd you get to the airport?"

"My friend Kurt Hummel drove me." Blaine replied. He noticed a flight attendant giving him a stern look. "Uh, Aunt Ellen, I'm on the plane right now, so I need to turn off my phone. I'll see you tomorrow morning. Bye!" He hung up and turned his phone off. The flight attendant nodded, gave him a satisfied look, then continued on.

There wasn't much information about the Cambion- either online or at the library. Just what Castiel told them already, and they're supposed to be unrehabilitated.

"Well, so much for getting more information." Dean grumbled as he slammed a book shut. "Any luck on your end?"

"Nope." Sam slumped his shoulders. "We're going in blind."

"Now, let's just hope Cas hasn't gotten to Jesse yet." Dean responded. He pulled out his phone, which was turned off. "What the hell? When did I turn my phone off?" He turned it back on. He noticed he has a voicemail message from Ellen.

"Hey, Dean. It's Ellen. I just wanted to make sure that you know that Blaine is heading to Nebraska to talk Castiel out of something. I just barely found out. Jo and I had just got back from Toledo when I saw his note. When I called him, he was already on a plane."

Anger and worry boiled up inside Dean. He gripped the phone and checked the time of Ellen's call. It was three hours ago. He whipped around glaring angrily at his brother, who held his hands up to calm him.

"Dean…"

"I asked you…I told you not to involve my son in this!" Dean said angrily.

"I thought he could help talk Cas down." Sam explained calmly.

"Really?! Did you think that he might be in danger if that demon shows up? Or if Cas tries to kill Jesse, Blaine would get caught in the crossfire?" Dean asked, advancing slowly towards his brother. "Blaine isn't trained enough to deal with this kind of thing!"

"I'm sure Cas has enough self-restraint to not let anything happen to Blaine." Sam reassured him.

Dean nodded, then pointed at Sam. "You better pray he does."

15 Minutes Earlier…

At Jesse's house, Jesse gets a cup of water from a five-gallon jug. He turned around to see a strange man in a trench coat. He backs away, dropping the glass, which smashes.

"Don't be afraid. I won't hurt you." Castiel said calmly as he advances, carrying Ruby's knife behind his back.

Jesse continues to back away. "Mom! Dad!"

"Your mother and father are sleeping. I assure you, they won't wake until morning." Castiel replied. Jesse started breathing hard.

"I'm sorry." Castiel was about to raise the knife when Blaine kicked the front door open and made the knife appear in his hand. Castiel whirled around and stared at him in shock. "Blaine, what are you doing here?"

"I came to stop you." Blaine said simply, walking into the house. "Castiel, I'm a Nephilim. I am half-angel, half-human. Nephilim's are supposed to be evil, but I'm not. Why should a Cambion be any different?"

"You wouldn't understand, Blaine." Castiel replied. "Now please, stay out of this."

Blaine frowned and stepped in between Castiel and Jesse. He folded his arms. "If you kill him, you'll have to kill me, too. I'm one of the good guys, but it could have easily gone the other way. So you might as well kill me, too."

Castiel considered this. He didn't want to hurt Blaine, but he didn't want the Cambion to live, either. "Then, I'm sorry." He shoved Blaine out of the way, grabbed the knife, and was about to raise his knife at Jesse, when Jesse unknowingly turned Castiel into an action figure.

Dean and Sam burst through the door. He glanced towards Blaine and Jesse. "Was there a guy here? In a trench coat?" Jesse pointed to the action figure resembling Castiel. Dean walked over to it, picked it up, examined it for a minute, then set it on the mantelpiece.

Sam sat on a chair, Jesse on the couch, and Blaine on the armrest of the chair Sam sat on.

"Was he your friend?" Jesse asked.

"Him? No." Dean lied and shook his head.

"I did that. But how did I do that?" He asked in shock.

"You're a superhero." Dean lied again.

"I am?" Jesse asked, disbelieving.

Dean nodded. "Yeah. Yeah. I mean, who else could turn someone into a toy? You're Superman-minus the cape and the go-go boots. See, my-my partner and I, we work for a secret government agency. It's our job to find kids with special powers. In fact, we're here to take you to a hidden base in South Dakota, where you'll be trained to fight evil."

"Like the X-Men?" Jesse asked, getting excited.

"Exactly like the X-Men." Dean said, chuckling. "In fact, the, uh, guy we're taking you to, he's even in a wheelchair. You'll be a hero. You'll save lives. You'll get the girl. Sounds like fun, right?"

Before Jesse could respond, Dean was flung against the wall. A demon possessing Julia- Jesse's biological mother- walks in.

"They're lying to you." The demon said simply. Sam and Blaine stand up. The demon flings them against the wall with Dean. Jesse stands up. "Stay right there, dreamboat. Can't hurt you. Orders." The demon said to Sam. Then he/she turned to Dean. "You, on the other hand? Hurting you's encouraged." The demon then turned to Blaine. "And don't even get me started on the Nephilim." The Demon flicks her wrist and slams Dean against the opposite wall, then back.

"No! Uh!" Dean yelled, the grunted in pain.

"Leave him alone!" Jesse exclaimed.

The demon leans down to Jesse, speaking sweetly. "Jesse. You're beautiful. You have your father's eyes."

"Who are you?" Jesse asked warily.

"I'm your mother." The demon replied, simply.

"No, you're not."

"Mm-hm. You're half human...half one of us." The demon revealed.

"She means demons, Jesse!" Dean exclaimed.

The Demon straightens and holds up a hand clenched into a fist. Dean groans in pain. The demon leans back down to Jesse. "Those people you call your parents-they lied to you, too. You're not theirs-not really."

"My mom and dad love me." Jesse said firmly.

"Do they? Is-is that why they leave you alone all day? Because they love you so much? These people-these imposters-they told you that the tooth fairy was real and that your toys could hurt you and a hundred other things that aren't true. They love you so much, they made your whole life a lie. Look into your heart, Jesse. You've always known you weren't theirs. You've always known you were different. Everyone has lied to you. They're not FBI agents. And you're not a superhero." The demon ranted.

"Then what am I?" Jesse demanded.

"You're powerful. You can have anything you want. You can do anything you want." The demon answered.

"Don't listen to her, Jesse!" Dean exclaimed.

The demon holds up a hand and Dean groans. She then turns back to Jesse. "They treated you like a child. Nobody trusted you. Everybody's lied to you. Doesn't that make you angry?" Jesse clenches his fist. The room rattles. The demon looks up, exultant. The fire flares up and the lights flicker. "See? It does make you angry. But I'm telling you the truth, Jesse." Things began to shatter. Blaine worked hard to make sure nothing fell and broke, but the Cambion was too powerful. The demon continued. "Wouldn't it be better if there were no lies? Come with me and you can wash it all clean. Start over. Imagine that-a world without lies."

Sam jumped in. "She's right. We lied to you." The demon looks at Sam, eyes black. Sam ignored her and continued. "But I'll tell you the truth." The demon raises a fist. Something crunches. Sam tries to speak through the pressure on his throat.

"I just want...to tell..."

"Stop it." Jesse demanded. Sam drops to the floor, released. He gasps for breath. "I want to hear what he has to say."

"You're stronger than I thought." The demon said, amazed.

"We lied to you. And I'm sorry. So here's the truth. I'm Sam Winchester. That's my brother, Dean. W-we hunt monsters." Sam admitted.

"Except when you are the monster. Right, Sammy?" The demon taunted.

"Blaine is a Nephilim- half-angel, half-human." Sam continued. "And that woman right there, her name is Julia. She's your mother. But the thing inside of her, the thing that you're talking to-it's a demon."

"A demon?"

"He's done nothing but lie to you since the moment you met him. Don't listen to him. Punish him." The demon demanded.

"Sit down and shut up." Jesse snapped. A chair scoots up behind the demon, who is forced into it, silent. She struggles to speak.

"There's, uh, kind of a...a war between angels and demons, and...you're a part of it." Sam went on.

"I'm just a kid." Jesse said, stunned.

"You can go with her if you want. I can't stop you. No one can. But if you do...millions of people will die." Sam replied.

"She said I was half demon. Is that true?" Jesse asked.

"Yes. But you're half human, too. You can do the right thing. You've got choices, Jesse. But if you make the wrong ones, it'll haunt you for the rest of your life."

"Why are you telling me this?!" Jesse asked, a little freaked out.

"Because I have to believe someone can make the right choice, even if I couldn't." Sam replied.

Jesse thinks about this. He clenches his fist and looks at the Demon. "Get out of her."

The chair flies back against the wall. Black smoke pours out of Julia's mouth and vanishes up the chimney. Dean drops to the ground, panting.

"How did you do that?" Dean asked in amazement.

Jesse shrugged. "I just did."

Dean smiled. "Kid...you're awesome."

Jesse glanced at Blaine. "You're really half-angel?"

Blaine nodded. "Guilty as charged."

"Did you have to make the same choice I just made?" He asked.

"Yeah." Blaine nodded again. "It really wasn't a difficult choice. I don't want to hurt anybody."

Jesse nodded and then looks at Julia, slumped in the chair. "Is she gonna be all right?"

"Eventually." Dean said, looking at Julia. He then leans down and picks up the Castiel action figure, which fell down at some point. "Look, uh, truth is, he's kind of a buddy of mine. Is there any way you could turn him back?"

"He tried to kill me." Jesse said pointedly.

Dean nodded in understanding. "Right. Uh. But he's a-he's a good guy. He was just confused." Jesse says nothing. Dean sighed. "Okay. It's been a long night. We'll...talk about it later." Dean puts the Castiel action figure back on the mantel.

"What now?" Jesse asked.

Dean looks back at Sam and Blaine. "Now we take you someplace safe, get you trained up. You'd be handy in a fight, kid."

"What if I don't want to fight?"

"Jesse." Sam comes forward to sit in front of the Cambion. "You're powerful. More powerful than...pretty much anything we've ever seen. That makes you-"

"A freak." Jesse clarified.

"To some people, maybe. But not to us. See, we're kind of freaks ourselves." Sam smiled.

Blaine leaned forward. "Jesse, I know exactly how you feel. When I first discovered what I was, I didn't think I'd be able to live a normal life. But, as time went on, I became pretty good at hiding my powers and just living amongst normal people."

Jesse nodded to show he understood. "I can't stay here, can I?"

"No." Dean said sadly. "The demons know where you are, and more will be coming."

"I won't go without my mom and dad." Jesse said firmly.

"There's nothing more important than family. We get that. And if you really want to take them with you, we'll back your play. But you got to understand-it's gonna be dangerous for them, too." Sam explained.

"What do you mean?"

"Our dad...he would take us with him wherever he went." Dean explained.

"Where is he now?" Jesse wanted to know.

"Dead. A demon killed him." Sam answered.

"Look, Jesse...once you're in this fight..." Dean leaned down towards Jesse. "You're in it till the end, win or lose."

"What should I do?"

"We can't tell you. It's your choice. It's not fair. I know." Sam replied.

"Can I go see my parents? I, I need to...say goodbye."

Dean nodded. "Sure."

Jesse heads upstairs. Dean turned to Blaine, who looked down, slightly guiltily. "Blaine, look at me." Blaine slowly looked up at his father's disappointed and angry expression. "What the hell were you thinking?! You could have been killed! I asked you to stay out of this monster-hunting crap, and you deliberately disobeyed me!"

"I'm sorry. I thought I could convince Castiel not to kill Jesse." Blaine replied, near tears.

Dean stared at his son and sighed. He's been down this road before with his father. When John Winchester punishes his boys, he really punishes his boys. Instead of the normal grounding kids get from their parents when they were in trouble, Sam and Dean were either left at boys' homes or -to put it mildly- got a good spanking. Sam glanced at Dean nervously. He knew some people inherited their parents' less savory traits. He wondered if Dean is one of those people.

"Dean…"

Dean raised a hand to silence Sam. "You- not a word." He turned to Blaine. "You- grounded. One month. No TV, no video games, no internet unless it's for school, no phone, no shopping."

Blaine swallowed back a protest and nodded. "Yes, sir."

"And another thing…" Dean softened. "Don't call me 'sir'."

Blaine looked confused at that, but nodded anyway. "Okay. Sorry. Won't happen again."

"Good."

Sam examines the Castiel action figure and puts him back on the mantel without any of the care Dean showed.

"He's been up there a long time." Dean said. They all run upstairs and enter Jesse's room. It's empty.

"He's gone." They turned to see Castiel behind them.

"Where?" Sam asked.

Castiel shrugged. "I don't know. Jesse put everyone in town back to normal-the ones still alive. Then he vanished."

Sam notices a note on Jesse's bed and picks it up. "Hey."

"What does it say?" Dean asked.

"That he had to leave to keep his parents safe, that he loves them, and he's sorry." Sam replied.

"How do we find him?" Dean asked again.

"With the boy's powers, we can't. Not unless he wants to be found." Castiel responded.

Dean sighed and shook his head. "Cas, will you please teleport Blaine home?"

"Of course." Castiel grabbed Blaine's arm. Blaine glanced at Dean, who avoided his glance. In an instant, Blaine was back in his own living room. Ellen sat on the couch, drinking coffee.

Blaine sighed and turned to Castiel. "Thank you."

"You're welcome." Castiel replied. "Blaine, I'm sorry it came to this. But I didn't want that Cambion to destroy the entire world."

"Okay. I understand." Blaine nodded.

Castiel smiled and patted his shoulder. "By the way, Dean told me about your grounding. Don't try anything. I will be watching you closely." With that, he vanished.

Blaine sighed and turned to Ellen, who stood and walked over to him. "So…Nebraska. Was it worth it?"

"No." Blaine's shoulders slumped. "My dad and I have only known each other for less than two months, and already I've disappointed him."

"Did you learn your lesson?" Ellen asked.

"Yes." Blaine leaned against the wall. "I am grounded for a month with no freedom whatsoever."

Ellen closed her eyes and nodded. "It could have been a lot worse, you know."

Blaine thought about that. There are abusive parents out there, unfortunately. "Yeah, I guess that's true. You know, he wouldn't even look at me when Castiel was about to teleport me. He didn't even say good-bye."

"Blaine, he was worried and upset." Ellen explained. "He's mad, but he'll forgive you. Trust me- he won't give up on you."

Blaine swallowed. "You really think so?"

"I know so." Ellen held her arms open. "Come here." They hugged. "Aww. It'll be okay."

Blaine sighed. "I hope so."

Let the one month grounding begin.

Okay, so a few things:

I know there was probably only like a half hour between the time when Castiel vanished out of Sam and Dean's motel room and went to Jesse's. But for the sake of the plot, five hours passed.

Lima, Ohio doesn't have its' own airport. The nearest major one is clear down south in Dayton.

I realize I added a lot from the episode "I Believe Children Are Our Future". I'll try to add more original stuff later on.
