Summery: One life mistake that John makes will change the lives of his children and the Winchester's will get a new view on things.

a/n: This chapter is kind of slow, I had a hard time starting it and it's not very long, but this idea came to me and wouldn't leave me alone. Hopefully things will pick up and get a little better. If information is wrong I'm sorry I tried to sort everything out.

Chapter One:

June 1975

John Winchester's leg bounced up and down as he sat in his plane seat. Mary glanced over at her husband of one year. They hadn't had enough money when they'd gotten married to go on a honeymoon so they had saved up over the year and were no taking their honeymoon at their one year anniversary. "Would calm down, I know you're not afraid a flying, so calm down you're making me nervous."

"Sorry, it's just my ass is sore as hell."

"John, hush there are children on this plane."

"How much longer is this plane ride going to take?"

"Well we've been in the air for three hours already, so about five to four more hours 'til we're in London."

"Why couldn't we 'ave chosen somewhere in the states?"

"Oh come on John, this is going to be the one and only time we'll be able to get out of the country in a long time. When we have kids we probably won't get to do many trips in the states anyway why not splurge a little?"

Mary was met with a frown and silence. "Don't be like that, John, please don't ignore me. Fine, just maybe try to go to sleep and the trip won't feel as long," Mary replied turning to look at her book she had laid out across her lap.

Sometimes Mary believed that they had married to young and to quickly. There was no doubt that she loved John, but they often fought over the littlest things and it got tiring. Not an hour later Mary heard light snores coming from next to her, she glanced over seeing her husband sleeping soundly mouth a gap, head leaned back against the seat. She smiled and returned to her book.

Several hours later the co-pilot announced that they were getting ready to descend. Mary closed her book and put it away into her carry-on bag, before elbowing her sleeping husband. He jolted upright looking around. He rubbed his eyes. "We there yet?"

"Just getting ready to descend," replied Mary.

John sat up straight and made sure is chair was in the seated position so he wouldn't be harassed by steward or stewardess to put it up. His back was sore and he kept adjusting himself in his seat to try and find a more comfortable position. "Bulk your seat belt John," said Mary.

"I know, Jesus let me get comfortable first."

"When we land we need to find a currency exchange station so we can purchase some souvenirs."

"I know," replied John with irritation.

"Alright grumpy I'll let you wake up first," Mary joked back.

The flight slowly descended to the runway and pulled up to the gate, but it was another fifteen minutes before they were off the plane. It was just past eleven o'clock at night here in London, Mary and John were sore and tired from the traveling, but they weren't exhausted tired, it was only just after five pm in Kansas. They knew the time zone switch would screw with them for a couple of days.

They went and got their luggage first before finding a currency exchange. It was a slow processed there seemed to be a hundred people in front of them even if there really wasn't. By the time they got to their hotel room it was twelve thirty. Mary was beginning to worry about John he'd been pretty quiet for a long time now hadn't spoken at all sense they got off the plane. Sometimes she believed that John acted differently then his normal self, just on occasion, but it'd been happening sense she had made a deal with that Yellow-Eyed Demon to bring John back from the dead. She watched him for a moment longer. "John is everything okay? You've been kind of quiet."

John scrunched up his face. "Mary I'm fine, what would make you think I'm not."

"Well for one you've been kind of quiet and another you look kind of angry, your face is all scrunched up the way it is when you're angry about something."

"I'm not angry, it's just that we're not ready to have kids."

Mary was taken aback. "Who said anything about kids? Where did this come from John?"

"You, you mentioned kids on the plane ride. You make it sound like you want some."

"Well I do, don't you?"

"Sure I guess, but not right now. We barely had enough money to scrape this trip together let alone to be able to take care of any kids right now."

"Well we don't have any kids right now John so it's not something we really need to worry about."

"It's just that I keep getting dropped and bounced around from one mechanic shop to another and we have no real stable income."

"I know that John, but we don't have any kids to worry about right now and when I do get pregnant we'll deal with it."

"See that's just it you make it sound like you want a kid as soon as possible."

"It'd be nice John. I really want a family. Ever sense my parents passed…" said Mary trailing off.

"I know, but think about it Mary we should be in a steady job with some good money behind us before thinking about kids."

"John I understand, would you stop trying to convince me. I didn't bring up kids on the plane because I'm pregnant or anything. I was just stating that when you have kids you don't necessarily travel as much. I get that you're not ready to have kids yet."

"Know what I need some fresh air."

"What? John where are you going?"

"We've been cooped up with each other all day. I need a break," John replied slamming his hotel door on the way out.

Mary sighed and began to unpack. Sometimes John just had a one track mind. If he needed a break from her fine, in reality she needed one too. It wasn't easy traveling with some one all day being in airports and planes all day. Settling in would help calm her down and prepare her for the next couple days she'd be here with John.

Rebecca Phelps kissed her fiancé as she finished putting on her outfit for her evening out. "I still don't think this is a good idea," said her fiancé.

"Oh, Orville, don't worry so much, I'll be fine, nothing is going to happen."

"I'm not playing games here Becca. I don't think it's wise to go to a muggle pub for this girl party of yours."

"It's called a bachelorette party."

"Tell me you're brinin' you're wand with you?"

She looked at her fiancé with a raised eyebrow. "Of course, I'm not naïve. I'm concealing it of course, but I wouldn't go anywhere without it."

"Good, good you can never anticipate what muggles will do."

They were both silent knowing that wasn't the real reason thing's had been changing dramatically. Lord Voldmort was gaining power everyday and Orville was worried what might happen to Rebecca if she were to go in to muggle London, sure they were both Pure-Bloods, but that didn't mean they were safe. "I'll be safe I promise. I need to go out and do this Orville, please I'll be alright."

"I know, keep your eyes open."

"I will," she said and gave him a quick kiss before she left.

She met her friends in the Leaky Caldron where they dead walked out to muggle London down the street to a local spot. Where she proceeded to get extremely drunk well into the night.

a/n: There it is, the first chapter slow but hopefully it will pick up. I also plan posting this at Live Journal, but I'm not part of any communties yet and was wondering if anyone here is at LJ as well if they could recomend a good SPN community or HP community to join. Thanks so much ~StoryDreamer
