Chapter 1

Calypso Daffodil Potter, whom still wondered if her mother was still high on pain killers when she gave her Daffodil for a middle name, sits on one of the swings close to her home and she used the term loosely. She thought her life would have gotten better when she found out about magic instead it got worse, thankfully she had stunned Cedric before grabbing that thrice damned Port Key. Now the Dark Tosser was back and Fudge was burying his head in the sand. Though she at least did have the presence of mind to say she had only seen Death Eaters and swore this on her life and magic. Voldemort did happen to be a Death Eater, he was the head Death Eater after all. The fifteen year old knew that she needed something or someone on her side that no one could turn on her. Ron couldn't be trusted, the whole tournament fiasco proved that. Hermione couldn't either because of her authority figure fetish.

She knew she could count on Sirius and the twins but that was about it. She failed to notice a golden eyed teen with brown hair as messy as hers observing her. Train Heartnet was wondering why such a good looking girl was frowning like that. His attention is diverted to the local thugs and Calypso's head lifts, " Oh, Dudders, what do you want anyhow? "

" This is our park, Potter. "

It was then Calypso spotted her other observer, " You gonna tell him that, Piers? "

Train chuckles as the punks scatter, " They really don't like me since I have no problem with beating their asses into the ground. I'm Train Heartnet. "

" Calypso Potter, you have to be new around here, otherwise you would avoid me like the plague. "

" Unlike the rest of the idiots in suburbian hell I can think for myself. Why's a pretty girl like you look like you have the weight of the world on your shoulders anyhow? " Train asks her.

Emerald eyes blink at this and her head tilts to the side like a curious kitten. Train could feel his pulse kick starting at this, why did she look like no one had ever complimented her before in her life anyhow? " Simple, I have an insane inbred moron after me and no one will lift a finger to put him down permanently. The leader of the resistance against this inbred buffoon thinks murderers and rapists should be given second chances instead of just putting them down. He fights back with non-lethal force. "

Train considers all this and then he sees the scar, " Huh, did not expect the GWL to be in suburbian hell. I'm currently living in number seven Privet Drive. "

" Oh, good, I'll be locked out and I really don't feel like picking the lock and breaking in, can I crash at your place. " Calypso says, he was still treating her like a normal girl.

" You're trusting someone you've just met? "

" You're not a fanboy, thank Loki for that, if you were here to kill me you would have already done so, and Dudley is terrified of you. " Calypso states.

" The least I can do is take you out to dinner, Calypso. "

Train watches her eyes as she processes what was happening, " In what capacity? "

Golden eyes dim for just a bit, had no one ever just done something for her, " I feel like it, besides, a pretty girl like you deserves to have some fun. "

Calypso lets Train drag her off and finds that she's actually enjoying herself. It was when they were heading home that Calypso pales as she can start hearing the last moments of her parents, " Bloody hell, what are Dementors doing here? "

Train stiffens, " You're sure? "

" I'm bloody well hearing my parents be murdered by that Dark Tosser right now, yes, I'm sure! " Calypso snaps at him and the damned thing was she didn't dare cast a Patronus Charm either.

Train pulls out Hades, a gift from Belze for when he joins Chronos. He removes the bullets and smirks, " Leave this to me, I registered Hades with the Ministry and the ICW just in case plus, I am seventeen. "

Calypso nods, barely holding on to her consciousness. Train fires the instant the Dementors come into view and both of them just pop. He was quick to steady his companion, witnessing her parents murders at the hands of a madman was not a pleasant memory. He swings her up into his arms and races for number seven. Calypso allows herself to relax, her magic said she could trust him so she would. Thankfully Train had some chocolate on hand and feeds it to Calypso. After he gets her settled he frowns, he'd read the Daily Prophet, they were crucifying her at the behest of Dumbledore.

It was the whimpers that drew his attention and he curses under his breath, of course she would have nightmares. He slips into the room he had given her for the night and runs his fingers through her bangs, slowly calming the sleeping teen. Maybe he should have given her a Dreamless Sleep potion before letting her drift off? The older teen just settles himself comfortably and lets himself drift off. However not deep enough that he wouldn't wake up if someone entered his temporary home. Calypso doesn't even blink to find Train in her bed. She was used to curling up with either Fred or George in the Gryffindor Common Room. Everyone in the Tower knew that they considered themselves siblings.

Train woke up when she did and Calypso sighs, " Guess I need to go deal with my charming relatives. "

" I'll come with you, we can pack up your stuff since I really don't like the idea of leaving you alone with Vernon. " Train says, he made sure he had Hades with him and plenty of ammunition.

Calypso did make them breakfast first, " I'm going to eat before dealing with them. Might actually be able to get decent meals before I get back to Hogwarts. "

Train frowns at this, " How bad is it? "

Calypso sighs, " Before my letter came I was essentially their House Elf. Thanks to having a wanted criminal for a godfather they leave me alone for the most part. He's innocent but I haven't told them that yet. "

Train smirks, " You sure you're a lion? "

" I'm a snake in the lion's den. " is the prompt reply.

Calypso leads the way over to number four and walks in, " You ungrateful girl, where have you been? "

Train winces, she'd had to put up with this. Now he understood why she stayed at his place. " She got locked out accidentally and I allowed her to stay over at my house. I live at number seven. " Train says, golden eyes hard.

Calypso was quick to move closer to Train when Vernon walks into sight. Train pulls out Hades and holds it loosely in his right hand. Vernon takes in the gun and goes to sit at the kitchen table. He knew an alpha male when he saw one, Train would not hesitate to shoot him. Train waves a hand to summon all of Calypso's things, the fact that she was staying so close to him with her uncle around told him plenty and none of it was good. " You're one of those good for nothing freaks as well. " Vernon snarls only for Train to cock Hades' hammer back and level the gun at the whale.

" As big as you are a novice wouldn't miss. Calypso will be coming with me and if you even attempt to come anywhere near her I will end you, got it. " Train shrinks her possessions down and they walk back over to number seven.

Calypso sighs as her trunk is unshrunk and she gets to work on her summer homework. Train looks over her shoulder and nudges her when it comes to Arithmancy. The fifteen year old smiles at this, " How would you like to come to Hogwarts as my bodyguard, I am an heiress to several old families after all, Potter, Peverell, Gryffindor, Black through my godfather, and Slytherin through right of conquest. I am allowed a bodyguard. "

" Let me get a Sweeper license first, that way I can get some bounties before we leave. " Train says.

It only took Train one day to get a license as a Sweeper or Bounty Hunter, to celebrate he took Calypso to Diagon Alley, having hid her scar with concealer. She also wore Ravenclaw colors as well. He took her to a little known about shop, Mundanely Magical. The Potter heiress smirks and goes power shopping. Then they tour Knockturn Alley where Calypso gets another wand, several books and Train checks in with the Magical Sweepers. After Calypso's shopping spree they head back to number seven, Train had gotten himself a Nekomata that he named Loki while Calypso had gotten a puppy that she named Fenria since her pup was female. Fenria was actually a child of Fenrir and a Dire Wolf.

After Calypso is out for the night and the two new pets are curled up with her Train calls Belze, informing him that he wouldn't be joining Chronos after all. Belze was there in two hours to talk to his surrogate son in person. " I'm sorry, Belze, I'm a sweeper now and been hired as a bodyguard to the Potter Heiress. "

Belze looks at him, " You've met her, haven't you? "

" She's here right now. Dammit, I compliment her and she doesn't even know how to react to it, I'm pretty damn sure her uncle would have defiled her if not for the fact that she used her innocent mass murdering godfather as a shield. " Train states.

Belze sighs, " Hades is yours, I had Hades made for you and if you ever change your mind there will always be a place for you in Chronos. "

" I'm a sweeper, hire me on an as needed basis. Right now I have a teenaged girl that needs someone around her that isn't a sycophant. " Train states, not knowing that he had saved himself from meeting Creed Diskenth, his psycho stalker in several other dimensions.

" I raised you well and so did your parents. Miss Potter does need someone like you in her corner. Don't be afraid to ask me for help if you really need it, Train. "

Train nods, he was making his own decisions now and he had more than enough money to live on his own for a while. Once Belze leaves he slips out to catch a crook and get the bounty before heading home and sleeping. Train and Calypso settled into a routine of sorts, she'd cook breakfast since Train was not a morning person and he'd handle the clean-up, then he would have to handle lunch while they alternated dinner. He was also helping her out with her potions as well teaching her about basic safety, how the ingredients interacted and getting her brewing up to par as well. She was half tempted to hire him as her Potions instructor as well. They'd cleared him as her bodyguard with the help of Griphook and taken care of her accounts as well.

It helped that Train also got her to talk about things she wouldn't with anyone else, got her to vent since she couldn't be seen going to a mind healer. She'd be crucified in the media. She had also, on his advice hired a lawyer through Griphook and a PR person as well. This meant that several people were going to be taken to task for running roughshod over a Pureblood family name. That morning however Calypso was still in bed, hiding from all sources of light when Train made the mistake of opening the curtains. He got hit with a wandless stinging hex immediately. " Callie, you're the morning person. "

" Migraine Relief Potion and I might be civil. "

Train flinches, he'd seen how nasty a few females could get when in pain. He closes the curtains with a wave of his hand and summons said potion. He helps her drink it and uses a gentle warming charm on his fingertips while massaging her temples, " You didn't mention migraines. "

" Used to no one caring when I'm not at school. Even Snape treads lightly around me when I've got a migraine, it's worse when I'm also hormonal, the only ones safe from me are the Weasley Twins as they learned early on how to handle me like that. " Calypso admits, she was almost purring in contentment, her animal form was feline in nature.

" Well, I do care, Callie. " Train murmurs, though he makes note to stock a certain other potion as well for his female housemate.

Callie knew this, he just did things for her, little things that usually only the Twins would do for her. Then there were the looks when he thought she wasn't looking. The small lingering touches, Train knew she didn't like her personal space invaded so the touches were always light, gentle. Just like how the Twins got her used to them touching her as well. Their talks had also helped as Train genuinely wanted to get to know her, not the GWL, but her, Calypso Potter. For the first time her summer was actually looking up.

Train knew that as her bodyguard he shouldn't get too close but she also needed someone that she could trust fully, which was why she had learned about his past and his training. She had just rolled her eyes and told him about her second year at Hogwarts. After that she had learned how to use a sword from Nearly Headless Nick. One of the other ghosts had taught her how to use knives as well. Train was slowly getting her fitness up and working to undo the damage of malnutrition as well. Calypso always frowned at the potions but she drank them after making sure she knew what was in them, she did have some allergies after all.

Two weeks with Train and she was actually starting to look her age, was getting to a healthy weight, and she looked happier. Train was actually a licensed medi-wizard as well so her was allowed to treat all of Calypso's conditions, malnutrition being the worst. He also took her out to do fun things like a normal teenager and got her hooked on anime and manga. It shocked him that she went straight to Cardcaptor Sakura. Then he realized that she was actually trying to recreate the cards and sealing staff with runes, drawing, and Arithmancy. He shrugs and starts to help her, it was a good idea to have something unexpected on your side.

The very day they finished her deck and she discovered that chaos was her element to call upon, was when the Order of the Phoenix came looking for her. Thankfully she had her familiars or guardians for her Chaos Deck and her sealing wand in a mokeskin pouch she had picked up along with everything else that she didn't want anyone else getting their hands on. Fenria registered as a familiar and so did Hedwig, she had also filled out the appropriate paperwork and so had Train. They came towards evening just as Train had finally decided to test the waters with Calypso. The brown haired sweeper is cursing under his breath at the invasion of his home though Calypso quickly checks to see if Moony was her Moony or not.

" Potter, why are you at number seven? " Moody asks her.

" Train's my new bodyguard and quite frankly if not for holding my mass murdering godfather over my fat ass uncle's head he would have already added sexual abuse to his long list of crimes against me that the old goat gets swept under the rug. " Calypso states.

" Check with Gringotts, I am her bodyguard along with her personal healer, and a desperately needed friend that doesn't see her fame. " Train states, loosely holding on to Hades.

Loki was draped around his neck while Fenria was at her mistress' feet and ready to attack anyone that was a threat. Remus could see that his cub was much happier and she did look healthier as well. Train waves a hand and packs all of their stuff up before informing Moody that he was not flying all the Kami damned way to where ever they were going and his patient did not need that right now. Moody apparently had a deeply ingrained fear of healers because he listened. He showed them the piece of paper with the address and Train apparates them away, then knocks on the door while Calypso is cursing him out in his native Japanese.

Sirius was the one to answer the door and the female teen hugs her godfather before introducing Train. Then Walburga Black starts up and Calypso straightens, her emerald eyes steely, " Would you shut up already you bint. No one likes to hear you screaming at them and I may just let my bodyguard shoot your portrait to shut you up. I have Black blood in my veins through Dorea and I do happen to be a Metamorphagus. You'd think you'd be satisfied with the fact that Sirius isn't batshite insane like his cousin is! "

The portrait of Sirius' mother stares at her, gaping while Train has Hades trained on the portrait. The curtains shut on their own, " I see why you ran away, Sirius. "

Train holsters Hades and sticks close to his charge, he glares Mrs. Weasley down, " First, I am seventeen, second Calypso damn well deserves to know what the hell is going on, third, you are not my mother or hers, fourth, I am her bodyguard and personal healer, fifth, I actually care about Calypso and not the Girl-Who-Lived! " Train says coldly.

" Plus, this is my damn house, not yours, I'll tell her anyhow. " Sirius snaps.
