A.N Sorry this is late. I got Supernatural Season 6 last week and I spent the entire week watching it and then homework got in the way. To The Twelve Olympians yes you get cookies, I was hoping people would get the connection.

Chapter 4

The door creaking woke Percy up. He watched the shadow on the wall as the shape entered the room. "Morning." Sam's voice sounded. Percy rolled over to see his older brother standing with three cups of coffee at the foot of Dean's bed.

"What time is it?" Dean slurred; speech still full of sleep.

"5:45." Sam answered way too cheerfully in Percy's books.

"Did you get any sleep?" he groaned, recalling being woken up by Sam watching Jeremy Kyle at half one in the morning.

"Yeah, I got a couple of hours."

"Liar." Dean mumbled as he pushed himself into a sitting position. "You still having nightmares about Jess?" he said louder. Sam sighed and sat on the edge of Percy's bed causing it to sag.

"It's not just Jess; it's this life." Sam admitted.

"What about the life?" Percy asked grabbing the top cup and shifting himself into a more comfortable position.

"Come on Percy, we all know it has its problems."

"Yeah but we can't let the problems get to us Sammy." Dean said moving so he sat on the edge facing them.

"So you just leave everything at the door do you?" Sam said raising an eyebrow.

"Yep." Dean smiled but it slipped as Sam reached under his pillow and pulled out Dean's knife. "That's precaution." Dean said taking it back.

"Maybe for you but why does Percy also have one under his pillow?"

"Hey don't drag me into this. I just woke up." The youngest Winchester protested.

Before the conversation could continue Dean's phone rang. "Hello...yeah the poltergeist...we'll be there soon."

"Who was that?" Percy asked downing his coffee needing the extra energy.

"Jerry Panowski, he has a case for us up in Pennsylvania." Dean replied as he reached for his shirt.

"Thanks for coming." Jerry Panowski said as he led the brothers to his office. "You must be Sam." He said to the older one.

"Yeah." The giant said slightly confused.

"You went to Stanford right? Your Dad was proud of you."

"He was?"

"Don't act so surprised Sam; he was very proud in his own way." Percy said placing his hand on Sam's arm. He wanted to pat his shoulder but he was a dwarf compared to Sam.

Mr Panowski made sure nobody was nearby as he shut the door behind them. "A few days ago one of our planes, flight 2485, crashed. Only seven people survived including the pilot Chuck Lambert." Jerry said sitting down in his chair and started typing on his computer. "The company put it down to mechanical failure, but I think it's something else. This is the recording from the flight recorder." Subconsciously the three brothers lent forward as they heard the pilot radioing for help before a low crackle took over and then the recording stopped.

"We're going to need a list of survivors and a copy of the recorder." Sam said after a moment of silence.

"And any chance we could see the plane wreckage?" Dean asked.

"The survivors I can do but the wreckage is in a warehouse being held by the government." Jerry answered.

"We'll deal with the plane then." Percy said thinking about anything that could bring down a plane.

"I'll send you the files then." Jerry said as Sam handed over his email address.

Percy stood next to Sam as they waited for Dean to finish at Copy Jack. Sam was looking through the list of survivors again, making sure they hadn't missed anything. Percy was about to retreat into the back seat for some shade when Dean finally left the building. "What took so long?" he moaned.

"Hey you can't rush perfection." Dean reminded him holding a freshly forged badge to Sam.

"Homeland Security!" Sam said shocked.

"This is probably the most illegal thing you've ever done Dean." Percy sighed shaking his head, "And you've done a lot of illegal things."

"Well this is something people haven't seen a million times." Dean said as they slid into the Impala. "Anything off the flight recorder?"

"Yeah listen to this." Sam said opening his laptop.

He'd slowed down the crackle at the end so a low voice that gave Percy the creeps said, "No survivors."

"No survivors?" Dean raised an eyebrow. "But seven people survived."

"Yeah it doesn't make much sense." Sam agreed. "On the subject of survivors I suggest we go see Max Jaffe first."

"Why him?" Dean asked starting the engine.

"Because if anyone saw something it was him." Percy answered.

Percy watched as his brothers went past the blue sign that said, Riverfront Psychiatric Hospital, he looked back at the seating plan of the passengers. Max Jaffe had been sitting at the back of the plane so if anything had happened he should have seen it. Percy put the plan down before the words could start swimming in front of him. He stared out the window as he played with a small silver knife, he was careful not to drop it in case it ripped the seats and in response Dean would kill him. "Planes? Why would a monster or ghost bring a plane down?" He was so far in his own thoughts he jumped when his brothers returned and opened the doors. "Anything?"

"It definitely wasn't mechanical failure." Dean said.

"According to Mr Jaffe the man in front of him got up and opened the door at the back of the plane." Sam explained.

"But those things are impossible to open!" Percy exclaimed.

"Yeah he also said the man had strange eyes. Who was in front of Mr Jaffe?" Dean asked.

"A Mr George Phelps, do you think he was a monster?" Percy answered.

"Only one way to find out," Sam said, "I think we should go and pay Mrs Phelps a visit."

"Do we really have to wear these?" Dean complained as he and Sam got out of the Impala both wearing suits.

"We're gonna need to look the part Dean if we want to get in and look at that wreckage." Sam said pulling at his collar.

"I think you look great." Percy said trying not to laugh, leaning out the back window. "Very respectable."

"Well we're all about respectable." Dean said smirking. The talk with Mrs Phelps had revealed that Mr Phelps had a fear of flight but not that he was a monster in anyway.

"Right the plan. Sam and I go in as Homeland Security and Percy you keep an eye out, we'll keep in touch with these." Dean said handing Percy a walkie talkie and keeping one to himself. "We'll turn it on once we're at the wreckage. See you in a few minutes little bro." Sam smiled and followed Dean while Percy leant over to reach a pair of binoculars and trained them on the gates to the warehouse the wreckage was stored in.

A couple of minutes later his walkie talkie crackled and Dean's voice came over. "Come in Little Boy Blue, I repeat come in Little Boy Blue."

"Dean can you please stop with that stupid nickname." Percy moaned.

"Hey it's Batman over these remember. And no, I will not stop." Dean countered.

"What is that?" Percy heard Sam ask Dean.

"It's an EMF meter it measures..."

"I know what an EMF meter is Dean, but why does it look like an old Walkman?"

"Because I made it out of an old Walkman." Dean said and Percy could practically see the goofy grin of happiness on his face.

"Sure, come on we need to look around." Sam dismissed and Percy could feel Dean's disappointment at Sam's lack of amazement.

"Hey Batman you still need to teach me how to make one of those things." Percy said trying to cheer Dean up.

"Sure." Dean answered in a monotone voice.

"Hey come look at this." Sam's voice came sounding distant.

"What is it?" Percy said frustrated he couldn't see.

"I don't know a yellow powder of some sort." As Dean said that Percy watched a black car pull up with two guys in suits who got out the car and went into the warehouse.

"Shit! The real Homeland Security is here. They've gone in."

"Crap!" Came over the radio. "Quick Sam back door. We'll be out soon."

Percy sat holding his breath for a couple of seconds as the alarms started blaring. He kept his eyes peeled on the gates as his brothers came running round the corner and jumped over them before heading to the parked Impala, speedily getting in and driving off.

"Any idea what it is?" Percy asked as Jerry finished analysing the yellow powder they'd found. They were back in his office and had been waiting for twenty minutes feeling the after effects of an adrenaline rush. The warehouse had been a close call.

"Yeah, it's sulphur."

"Sulphur? Are you sure?" Sam asked leaning forward.

"Definitely sulphur but you can check for yourself." Jerry replied turning the microscope round so Sam could look. A loud bang outside caused them all to jump. "Excuse me I have an idiot to go fire." Jerry said leaving the room and immediately shouting at the morons outside.

"So if it's sulphur does that mean it's demonic possession." Percy asked.

"That seems most likely." Sam sighed. "So what do we do now?" Both Winchesters looked to their older brother.

"I don't know. This isn't what we deal with." Dean said rubbing his chin. "I mean this is gonna need research."

"Great, nothing I enjoy more then research." Percy said sarcastically, feeling a headache already coming.

"This is useless." Dean moaned as he picked up another book. Percy stood pinning more pictures to the wall, having given up reading ages ago. Sam sat diligently at his computer printing off more articles he'd found.

"Actually I may have something." He said.

"Go ahead." Percy said crashing into a chair next to him.

"So every culture has demon lore but in Japan they believe they can cause disasters. One can cause earthquakes, another causes floods..."

"And this one causes plane crashes?" Dean questioned.

"Appears so." Sam said running a hand through his hair.

"Maybe it found plane crashes gave it a higher body count." Percy put forward. "It would make sense."

"Brilliant." Dean said sarcastically as his phone started ringing. "Hey Jerry...wait what...where...how ironic...no we'll get there as soon as we can."

"What's wrong?" Percy asked feeling another trip coming on.

"The pilot Chuck Lambert is dead. He crashed a small plane in Nazareth, sixty miles from here."

"Great. Our day just keeps getting better." Sam muttered as he collected stuff to continue researching.

Percy sat in Jerry's office again for the third time in two days. He was considering calling the office home and moving in permanently. They'd found more yellow powder in Chuck's plane so had brought back to Jerry for analysis but they already knew the answer. "It's sulphur again." Jerry confirmed sighing.

"Perfect, just perfect." Dean muttered.

"I think I may have found something." Sam said looking up from his laptop for the first time in an hour.

"You gonna tell us or do we have to guess?" Percy grumbled sick of being stuck inside.

"Chuck's plane went down exactly forty minutes into the flight and so did flight 2485, in fact six planes have gone down over the past decade exactly forty minutes into their flights."

"What's so special about forty?" Jerry asked.

"Biblical numerology. You know it rained for forty days." Dean answered, "Anything else?"

"Yeah on all the previous flights there have been no survivors."

"Wait are you saying that the demon wants to finish it's work by killing off any survivors of 2485?" Percy said surprising himself at how quickly he understood the situation.

"Exactly." Sam agreed. "So now we just need to make sure none of the survivors fly."

Percy sat on comfy back seat of the Impala as Sam finished up his phone call to the final survivors. "They're not flying soon." He said crossing their name off the list.

"So Amanda Walker the flight attendant is the only one?" Percy asked.

"Yep, and her plane leaves Indianapolis at eight. Dean are sure you want to drive it's five hours?" Sam gave Dean a worried look.

"Just watch me Sammy." Dean replied putting his foot down on the accelerator.

"Dean can we go back, I think I left my stomach behind." Percy teased from the back.

"No time. You'll just have to live without a stomach." Dean remarked.

"Nice to know you care so much."

"Having no stomach is a good thing; we'll cut our costs in half if you're not eating pancakes." Sam added.

"Hey no ganging up on me!"

"Who are the legal adults here?" Dean asked and in response he and Sam lifted their hands.

"Since when have we ever cared about being legal? I've done lots of things that even legal adults can't do!" Percy argued.

"We've brought him up too well Sammy." Dean said wiping away a fake tear.

"Do I want to what you're referring to?" Sam asked raising an eyebrow.

"Probably not."

Sam smiled to himself; this was one of the few normal family moments they had. "Percy you should probably get some sleep, and before you say you're not tired, I don't want to deal with you in two hours' time when you're tense and hyperactive."

"Fine. But only if I get to drive in two hours' time."

"Nobody's driving Baby but me!" Dean snapped protectively.

"Do you not trust me?" Percy pulled an offended look.

"No. Now do as Sam said and go to sleep."

"Just because you're older than me doesn't mean you can order me about, Princess." And so the insult war started until Percy fell asleep to the sound of the Impala's engine.

They burst through the airport doors and ran to see the departure boards. "We have thirty minutes left." Percy said looking at his watch.

"There's Amanda's flight, gate eight." Sam pointed at the board. "And she still isn't answering her phone."

"Come on I have a plan." Dean said leading them to the customer service phone. "Hi I'm trying to reach Amanda Walker flight 424, sure I'll hold..." He spoke into the phone. Percy started tapping his foot; the hair on the back of his neck stood up. He had a bad feeling settle in his stomach as Dean made up some lie to Amanda, which judging by the way he faltered wasn't going well. "She's still going on the plane." Dean said frustrated, slamming the phone down.

"Right then we'll have to get on that plane." Sam stated.

"What? No! No way in Hell." Percy protested at the same time Dean said,

"We can't do that."

"What's wrong with you two?" Sam asked worrying about the time they were losing.

"Me and Percy can't...you know." Dean answered miming a plane taking off.

"Neither of you can fly?"

"No, Dean just hates flying and I feel like I'm gonna be blown out of the sky, like I'm trespassing." Percy told Sam truthfully.

"Fine you two stay here and I'll stop her." Sam said.

"You are not doing this alone." Dean said, going into protective brother mode.

"It's either that or you come with me. We don't have that long before the plane crashes." Sam argued whispering the last part. Percy gulped. They all knew that they would choose to save people no matter what.

"Sam you buy the tickets; we'll come." Dean said admitting defeat.

"Come on Dean we'll get what will pass through security." Percy pulled his brother back towards the exit and the Impala as dark clouds gathered above them. 'Great.' Percy thought. 'On top of everything else there's going to be a thunderstorm.'

They each sat in their seats with Percy be the window, Sam in the middle and Dean by the aisle. They hadn't even taken off yet but Dean had the seat in a death grip and Percy looked like he was about to faint. "Both of you need to calm down." Sam said soothingly just as the engines roared to life and the plane taxied on the runway.

"Easy for you to say Sam, you don't have a fear of flying." Dean said through gritted teeth. Percy shut his eyes, grabbed Sam's hand and squeezed it tightly as the plane picked up speed and took off. "That can't be normal." he heard Dean mutter.

"Dean just calm down, you too Percy. One, this is how the demon possess you, and two, you're cutting off the circulation in my hand."

"Sorry." Percy said opening his eyes and releasing Sam, who now had imprints of Percy's fingers. He reached into his bag and retrieved a bottle of water he'd bought in the waiting room.

"Dude are you humming Metallica?" He heard Sam whisper to Dean as the cool liquid ran down his throat. Immediately he felt calmer still nervous but less so. What was worrying him now was the thunderstorm that seemed to be getting stronger every minute.

"Are you Amanda?" Dean asked one hostess who walked past them after the seatbelt sign had disappeared.

"No sorry." The hostess replied before continuing forward to the passengers.

"She must the one at the back then." Dean muttered.

"We need to see if the demon is in her." Sam said wincing as Percy gripped his arm again as the plane hit turbulence.

"Way ahead of you Sam." Dean said pulling a bottle of holy water out of his bag.

"You're not flicking holy water at her; you can be more subtle than that." Percy gave a weak laugh at the thought of Dean being subtle. "If she is possessed she'll flinch at the name of God."

"Fine and how will I bring that up in conversation?"

"Use the usual Dean charm." Percy answered.

"Fair enough." Dean said standing up and almost falling over as the plane hit more turbulence.

"Dean," Sam called him back. "You have to say Christo. It's the Latin."

"I know Sam. I'm not that much of an idoit."

"You okay?" Sam asked Percy who looked deathly pale.

"No. I feel like I'm gonna die any second and this thunderstorm isn't helping."

"Percy you have to breathe okay. Breathe with me. In, out, in, out." Percy followed Sam's instructions and could feel his heart rate decreasing.

"Thanks Sam."

"What are brothers for?" Sam replied as Dean sat back down.

"Well it's not in her. She must be the calmest person on the plane."

"We should check for EMF. That could lead us to the demon." Percy said.

"We need to find it quickly though and then how do we get rid of it?" Dean said before panicking at another round of turbulence.

"Dean take deep breaths. I found an exorcism that happens in two parts. First we get the demon out of the host, which actually makes it stronger."

"What?" Percy cut in. "Why would we make it stronger?"

"It would no longer need a host but the second part sends the sucker back to Hell for good."

"So all we have to do is make sure it doesn't kill us while it's stronger." Said Dean, ever the optimist. "I'll go check for EMF." He reached back inside his bag bringing out his old Walkman.

Percy sat back in his seat as Sam stood up to talk to Dean who had now made it to the front of the plane. He started his old routine of counting to calm himself. Dean had got him to do it during storms when they were in motel rooms. Now he did it whenever he felt scared as it gave his brain something else to focus on. "Percy come on." Sam said as they walked past, he moved quickly struggling to stand properly.

"You okay?" Dean said supporting him.

"Yeah just been sitting for too long. What are we doing?"

"The demon's in the co-pilot, we need Amanda to bring him back to us."

"Wait we're going to tell her?" Percy said thinking back to their dad's rule of never tell unless there is no other option.

"Only what she needs to know." Dean answered quietly as they reached her. "Hello, listen we need to speak to the co-pilot and we were wondering if you could ask him to come back for us." Sam asked politely.

"Why do you need to speak to him?" Amanda said looking confused.

"Ten minutes." Percy said looking at his watch.

"Listen Amanda we don't have much time." Dean said taking charge. "We know you were on flight 2485 and something was on that plane which caused it to crash, the same thing killed Chuck Lambert in another plane crash. And now it's gonna bring this plane down as well killing everyone on board."

"What? Who are you?" Amanda said shocked.

"Listen, Amanda please we can stop the plane from crashing but we need the co-pilot." Percy told her looking directly into her eyes.

"I'll go get him." She said reluctantly, moving down the plane to the cockpit. Sam and Dean closed the curtains and just watched through a gap.

"Sam got the book?" Dean asked not taking his eyes off the front of the plane.

"Yeah."

"Percy got the Holy Water?"

"Yep."

"Good I've got the duct tape. He's coming." The boys stood to one side as the co-pilott stepped through the curtain. Dean immediately tackled him covering his mouth with tape. Percy squirted it with water causing steam to appear before helping pin the man's arms down, while Sam held his legs.

"What are you doing?" Amanda gasped.

"Just leave us to this we need you make sure no one comes in." Sam ordered but Amanda didn't move not taking her eyes of the scene in front her.

"Amanda, please." Percy pleaded which brought her out of her trance. She nodded and went back closing the curtains behind her. Sam started reading but Percy was too busy trying to avoid being hit with a flailing arm, unfortunately Dean lost his grip as the plane hit more turbulence allowing the left arm to be free so the demon ripped off the tape and hit Percy. As Percy fell back Sam went dropped the book and took his place.

"I know all about your girlfriend." The demon taunted Sam. "Her screaming as she burned." That made Sam snap. He punched the demon in the face.

'That's gonna hurt in the morning.' Percy thought as he moved to pin the man's legs.

"Sam keep going!" Dean shouted as he regained his grip on the other arm.

With a minute left Sam finished the Latin as they watched black smoke come from the guy's mouth and disappear into a vent. The boys let go off the now unconscious body. "Shit." Percy breathed, his heart pounding in his chest. He suddenly felt weightless for a second before he felt the falling sensation. The plane filled with screams as the power cut out and the plane was a prisoner of gravity.

"Arrgh!" Percy looked over to Dean who was holding tight to the door screaming, he forced his eyes to stay open and looked for Sam. Through the doorway he saw Sam, somehow standing on his feet, shouting the last part of the exorcism. As he finished a bolt of lightning hit the plane and power was restored.

The pilot regained control bringing it back to a horizontal position. Percy collapsed on the floor breathing heavily. He could feel the adrenaline pumping through his system and the blood roaring in his ears. "Dean! Percy!" Sam's voice sounded as he ran to his brothers.

"I'm okay." Dean said; his breathing still fast.

"Percy?" Sam asked making his way to where their younger brother lay on the floor. There was a moment of silence before a grumpy voice responded.

"We are never flying again."

"Thanks boys, that's two I owe you now." Jerry joked as they left his office.

"It's alright. Call us again if you need help with anything." Sam said smiling, but behind the smile was worry. He couldn't get what the demon had said out of his head, despite Percy and Dean telling him otherwise.

"Hey Jerry I've been wondering how'd you get my number? I haven't had that long." Dean asked.

"Your dad gave it to me, I mean not directly but I got it from him. See you around." Jerry said turning away.

Percy got out his phone as they walked back to the car and called their dad. It went straight to voice mail but it had a different message this time. All three of the crowded around the small device listening to their dad's voice for the first time in weeks. Or at least weeks for Dean and Percy; for Sam it was the first time in two years.

"This is John Winchester. I can't be reached. If this is an emergency call my son Dean. 785 555-0179. He can help." The brothers stood in silence.

"What now?" Percy asked.

"We keep doing what we're doing and hope for more information." Dean said.

"Dean we can't keep waiting." Sam said frustrated.

"Until we have more information about his location we continue how we are."

"Don't argue." Percy sighed. "Let's just go back to the motel and sleep. We'll discuss what to do when we're no longer tired."

"When did you become so wise?" Dean joked.

"I've always been wise." Percy laughed opening the door to the back of the Impala. "Now shut up and drive Princess."

A.N I was planning on having a scene where they insulted each other such as Sam and Dean calling each other Bitch and Jerk but I couldn't think of good names for:

Dean to call Percy

Percy to call Sam

Sam to call Percy

Please if you have any suggestions please put them in the reviews. Thanks.
