So, it wasn't going to be originally, but now I'm going to make this an Harry/OC story, (Also if anyone can recommend me some good Harry with OC because I can't find any)

She walked down the street, it was a path she knew well. Bobby Singer had visitor so she was given money to go to a local diner and get herself some food. They were both aware that meant a cupcake and a chocolate milkshake. As she went to the diner she saw two familiar people sat down in a booth, there backs were to her as she entered. "Hey Missy" she said to the woman behind the counter.

"Hey there Katherine-Mai, back from another year at school?" She smiled "I got in a new shipment of red velvet, I'll bring it over to your usual seat" She said with a wink. Katherine smiled excitedly before glancing at the two boys in the corner.

"Uh, actually I'll have it to go" she said to Missy who looked surprise "Also, can I send two slices of Cherry pie to that table over there" She added. Missy was confused but complied, getting the girls order and handing it to her before walking over to the two boys, one looked mid to late teens whilst the other could have been early twenties.

She set the pie down in front of them both "Uh, sorry, we didn't order this" Sam Winchester said whilst Dean glared at him, hoping to take the pie anyway. The waitress smile sweetly at the pair of brothers.

"Oh I know, a girl called Katherine-Mai ordered it for you" she said, both boys eyes widened at the name "Real sweet girl, think she might have her eye on one of you if the pie is anything to go by, young but a real sweetheart. She goes to boarding school in England during the year though, only comes home for summer" Missy added. Sam and Dean exchanged looked.

"Boarding school? Since when?" Dean asked.

"Uh, I'd say when she was eleven" Missy nodded before walking away. The two Winchesters sat in silence for a while.

"Think that's why she ran away? To attend school?" Sam asked. Dean shook his head, glaring angrily at his pie, suddenly having no appetite for it.

"I don't think she ran away at all, I think that was a cover story" Dean said darkly, "Common, we can see what dad knows" he decided.

"What the hell are you laughing at girl?" Rufus Turner asked Katherine. Rufus was a good friend of Bobby's, and they often helped each other out of a rut, he found Katherine to be amusing, although annoying at time, there was only so much happiness he can take before it makes him want to shoot his brains out. Such as now when she was laughing so hard no noise was coming out and she was left wheezing on the floor from where she had fallen out of her chair.

"Nothing" She replied, wiping tears form her eyes "Uh, my friend Harry, sort of blew up his aunt. Not like, explosion" she added hastily, seeing Rufus's wary glances "But he writes it so nonchalantly. I mean its not all funny, he's thirteen and has been kicked out of home now" She added seriously before perking up. "Hey Bobby" she called, running out of the room, bumping into a wall on the way.

Rufus chuckled a little to himself, he knew what she was going to ask, she had been pouting about being left alone in the house since she found out this morning, and the pair of hunters would be gone for a week or so. That girl had Bobby wrapped around her little finger and neither of them knew it. Rufus did though, when she came back with a bright smile and a old man rolling his eyes. "Let me guess, you convince the old guy to let your friend stay" Rufus said with a raised eyebrow and pointed look.

"What can I say, I'm adorable" she shrugged. She quickly sent Harry a letter, there was four weeks left of the summer holidays and she didn't want him to spend them all alone in the leaky cauldron, a lively but oh so dusty pub where very strange witches, wizards, banshees and others all came to stay. All he would have to do was floo to Bobby's house, all he would have to say is Singers Salvage Yard, south Dakota, and he was here. She used Hedwig to send the letter after feeding her some bread and a drink of water.

Smiling at Bobby she nodded her head as he gave her his usual talking too "Keep an eye on the phone's I'm expecting a call from a hunter name Harrison, just give him the numbers I wrote down on the desk, left some money for you to feed yourself and that friend. No sharing rooms and don't touch anything unless you know what it is." he said before leaving, rolling his eyes as she saluted him. "Idjit" she heard him mutter as he walked out.

It was a loud "OW" that alerted her Harry had arrived, she hadn't even known he was coming until that moment, but clearly he received her note if he was here. "Hey Kathy" he smiled as she walked in. "Wow" he added under his breath, looking at the room he had arrived in. it was Bobby's library. The walls of which were covered in papers, extracts of books and pictures of creature, pinpoints on a map and warding sigils on the windows. There was books everywhere in various stacks and three large bottle of whiskey, all various levels of being emptied, and a large symbol on the floor. It was so different to the immaculate home of the Dursleys, although clean, it looked so un-organise but so well kept at the same time. "You look nice" he told her and it was true. For the first time since they met he was the same height as her, around five three. Her hair that used to be frizzy, although not so much as Hermione's, had grown out to long, loose curls, the colour looked even darker as a consequence. Her parted bangs were gone, replaced with a curtain fringe, her face had thinned out as well, she was starting to loose the childhood chubby cheeks. It was amazing what a few weeks away from a person could do to make you notice the difference in how they look.

She was dressed in a pair of denim dungaree shorts over a short sleeve grey shirt. Harry couldn't read the writing on it because it was covered, but knowing Katherine it would be something quirky. On her feet were a pair of sturdy floral ankle boots. Her arms and face were a little red from where she had caught the sun but she didn't seem bothered by it as she gave him a bright smile. Harry himself was in a pair of too big baggy jeans and a simple baggy grey shirt. He had this shirt for years but since it used to be Dudley's it was only just starting to fit now. Katherine had to admit he looked nice, much it her horror, he looked attractive even. She almost gagged at that thought about her best friend who's hair was more unruly than usual and eyes a brighter green than the previous years. "Here, I'll show you where you'll be sleeping" She said to him and he followed her up the stairs, tripping a little on a weird statue there "Oh yeah,… don't ask" She said as they took in the gargoyle type statue.

They walked into the room he would be staying in. It was simple, there was two single beds, a small desk as well as a wardrobe and chest of draws. There was a mirror on the wall as well but it looked like it hadn't been dusted in a while. The whole room looked like it hadn't been touched in a long time but the bed covers were clean "Yeah, nobody has stayed in this room for a while, mines across the hall as indicated by my initials on it, bathroom is directly to your left, probably best to stay out of any other room on this floor to be honest, apart from the airing cupboard, which has towels in it" She said thoughtfully "And blankets if you get cold" she added.

"Thanks Kathy" Harry smiled

"No problem, Bobby is away for work for the next week or so, and you saved me from boredom" She said with a shrug and one of her signature winks. Harry chuckled before turning mockingly serious.

"Oh, suddenly I feel so used" he said, putting a hand over his chest and she laughed, nudging him with her shoulder before sitting down on one of the two beds.

"So, tell me how you blew up your aunt?" She asked eagerly and Harry looked sheepishly at her, telling the story about how she had insulted his parents, how they were making up lies about them and how he lost his temper. She couldn't help but laugh at the explanation of the horrid sounding Aunt Marge inflating like a big balloon.. "So you didn't get your Hogsmeade letter signed?" She asked him.

"No" Harry said sadly

"Want me to forge a signature?" She wondered.

"Wouldn't work, this is Dumbledore we're talking about" he pointed out and she shrugged but nodded. "Have you heard the news, apparently some killer named Sirius Black escaped Azkaban. He murdered thirteen Muggles and was Voldemorts right hand man apparently" Harry informed her and her eyes widened.

"Seriously… no pun intended" she added and he nodded, smirking a little "Damn, and I thought Azkaban was suppose to be impossible to escape. What with the dementors and all. So glad they're only a thing in England" she said, shuddering slightly. "So remember how you told me you never got to do a lot of muggle sports when you were younger even when you were in primary school?" She asked Harry who nodded wondering where she was going with this. "Well my dear English friend, tomorrow I shall fix that" she said enigmatically before grinning "Basically I know all the places you can hang out around here for free, and there is a batting cage that doesn't charge" She said happily.

"Like, beaters in a game of quidditch?" Harry asked and she nodded. "Sounds good" he agreed happily. He had a feeling this would be one of the best summer holidays ever, and last year was pretty amazing with the two weeks he spent at the Burrow with the Weasleys. He looked at her sheepishly as his stomach growled "Don't suppose I could have a sandwich or something?" He asked her and she jumped up with a shocked expression

"Crap, I had pizza in the oven" she yelled, running out of the room calling "Don't worry my friend, I'm coming" to the inanimate food cooking in the oven, making Harry laugh at his friends quirks

Harry had gotten use to staying at the Singers place over the past six days, he had gotten used to there being a wall of phones labelled with FBI or CDC or Police, and the fact they ring almost all the time. He enjoyed visiting the diner where the waitress Missy doted on the pair of them. He liked the freedom he had here. He had learned more about Katherine and her family in that one week than he had in two years of school, given she was petrified for the majority of their second year, but the point still stands.

It was on the sixth day that Bobby came back, a day early. The pair were using kebab skewers to melt marshmallows in the fireplace in the library, because it was another thing Harry had never done, and for once it was raining as appose to the heat wave that had previously been experiencing. "Mai?" She heard his gruff voice call.

"Library" She called back and the man walked in, seeing the two teenagers sat on the floor, "Marshmallow?" She offered, Bobby looked at the pair incredulously.

"Marshmallows? I thought you hated them, said they were like cotton buds high on additives" He said whilst Harry tried not to choke on the sweet he had put in his mouth. It sounded like something his blunt friend would say.

"There nice melted. 'sides, why'd you only put the aging memory of yours to use when it's to contradict my actions with something I've said?" She asked.

"My memory is fine, any more wise cracks from you and you know where that skewer can go" He said to the girl whilst Harry gulped, catching this action the girl winked at him.

"That means I love you in Singer talk" she said, whispering it loudly so the man could talk.

"Idjit" he scoffed, Harry smiled a little, Katherine often called him and Ron that when they do something idiotic, admittedly that was often. "You must be Harry Potter" Bobby said to the boy who nodded shyly, standing up to be respectful. "Mai told me 'bout you," he said "Your aunt and uncle, they ever need reassuring that her threats stand, I'll be happy to oblige" he told the boy and Harry glanced at the shot gun in Bobby's hand, nodding tensely "Now you two get out of here, clean up your mess as well. I got work to do" He said.

"And that is Singer talk for looking through books for hours." She whispered loud enough for the man to hear, making Bobby roll his eyes "Don't worry Bobby, already told the boy you're a genius, no need to try and hide it" She called as the pair walked out of the room and Bobby chuckled whilst shaking his head, this must be what's it's like to have a normal teenage girl, he felt himself thinking, she poked her head around the door after leaving "Oh, and I'm making chilli for dinner, your favourite" she added with a smile, proud she could make that one meal, leaving the man to his work.

They walked out of gringotts bank two days before having to return to Hogwarts, Harry collecting money from his vaults, and Katherine-Mai converting muggle currency to wizarding one. He had found great amusement in watching her play for that money. Sat down in a bar owned by a kind woman called Ellen, and Ellen's daughter Jo who was the same age as the pair, Harry watched as several older men, all gruff looking and not people Harry would like to mess with, let Ellen deal out some cards to the group.

He hadn't a clue what was happening, who was winning or even how the game works, the rules were also lost on him. "So, they're playing for money, what if she loses it all?" Harry asked Jo who just shrugged

"She won't, maybe some here and there but Mai's a pro, been playing this game her whole life. 'sides, you ever had her glare at you? It's off putting stuff" Jo added and Harry had to agree with a smile. He watched as she earned more and more money, smirking smugly at the loosing men. Sure she lost some herself but in the end she was quite a bit better off.

Back in the leaky cauldron, with all their shopping done, Katherine-Mai and Harry walked into the main bar when hearing a commotion. The two grinned when seeing Hermione and Ron fighting "Is that a cat or a small lion Hermione is holding?" Katherine murmured to Harry who sniggered.

"I wish I could tell for certain" Harry replied to which they both laughed under there breaths but loud enough to catch the attention of their two friends who immediately turned and beamed at them. Katherine and Hermione were instantly embracing one another with a squirming cat in between them before the Weasley twins spotted the action and ripped Katherine away form Hermione in order to have a group hug with the girl, putting one arm around her each of her shoulders.

"Hey there you two, how was Egypt? Your hair is longer" Katherine commented.

"Ron got around to showing you the article yet?" George had to ask, his younger brother had been showing everyone. The girl shook her head "He will" George said.

"Be fair Georgie, he's only told the day maid-" Fred said.

"And the night maid-" George added

"And Tom-"

"And the cook-"

"Not to forget that bloke that fixed the toilet" Fred said as if that was very important.

"And that wizard from Belgium" George nodded.

"And Harry" Chimed in Katherine to finished, looking behind the two where Ron had indeed whipped out the newspaper article and was showing the boy who lived. The two gingers and Katherine all started laughing, not being able to stop and it wasn't even that funny as far as their jokes go.

"You two better be behaving. Oh hello Katherine dear, how was your holidays? Harry stayed with you and your uncle I hear? That's very kind of him. How is he? Bobby isn't it? Arthur rather enjoyed his company when they met last year" Molly Weasley bombarded a bemused Katherine with questions, making the twins laugh.

"Hi Mrs Weasley, I had a good holiday thanks, probably not as exciting as yours, Egypt is on my list of places to visit, and yes, Harry stayed with me, it was fun, I taught him a bunch of card games. Bobby's awesome, he liked Harry staying because it meant I didn't bother him so much when he's trying to work, that and I always make too much food when I cook so Bobby doesn't have to pretend he's still hungry and eat some more" Katherine smiled sweetly at the woman who touched her cheek motherly

"That's good dear. No have you packed everything, all your books, folded your clothes? Everything organised?" the ginger woman asked her

"Yep" Katherine nodded

"That's good, good" Molly nodded "I know for a fact you two haven't, so get do it" She added to the twins to agreed, grumbling as they did so, but climbed the stairs nonetheless. Katherine walked over and sat next to Ron, opposite Harry, looking at the article "Nice picture" she complimented. Rom smiled smugly.

"Thanks" he grinned, trying to sound nonchalant. He didn't succeed in his attempt.
