June 22nd, 1975 – Hogwarts Med Ward

"Uhg my head…" Katrina groans placing a hand to her aching head; she blinks slowly remembering where she is and what the last few days or more like years of her life had been. She was 15 again… holy shit… She sits up quickly, wincing as the movement stretches her wounds and sore muscles. She quickly grabs her glasses form the side table and looks down at her arms that are wrapped in white bandages, she can't find her wand. She takes in her surroundings and comes to the conclusion she must be in the Hogwarts Med Ward considering the many beds along the walls. A woman comes out of a door… her office Katrina assumes, walking over to Katina with a tray filled with multi-colored potion vials.

"How are you feeling this morning dear?" The woman asks her kindly. It takes a lot of willpower not to instantly trust the woman who she knew as a friend in her old life but to act like a scared 15 year old.

"Where's my wand? Who are you? I want my wand." Katrina asks sounding frantic and terrified, it paid well to be a good actor in times like these or so Sirius used to say. The woman frowns and sighs setting the tray down and pulling her own wand out.

"Professor Dumbledore has your wand dear, I'm sure he will return it to you when he visits later, if you want that visit to come sooner then you best cooperate. The sooner I get you back into a good condition the sooner I'll let him visit you. As for who I am, I'm Poppy Pomphrey I'm the Matron or Healer here at Hogwarts, you were lucky I was here last night when the headmaster brought you in, as it is the summer holidays." She explains. Katrina slowly nods.

"I… I'll cooperate… but only if you show me your left forearm." She stutters out at first, her voice growing stronger with conviction as she talks. Pomphrey frowns but shows her unblemished dark mark free forearm. Katrina visibly relaxes. "You're not one of them… okay, I'll trust you…" Pomphrey smiles sadly at the girl.

"I'm going to run a diagnostic spell on you and we'll go from there alright?" she asks not doing anything until Katrina nods. She waves her wand over Katrina and a paper forms, quickly filling with words. The list goes on for a while, Pomphrey's face contorting into a look of horror as she reads. "Well it seems I have a lot of work to do… What's you're name dear and how old are you?"

"I'm 15… I turned 15 in May… it would say my age on your sheet. I was born May 21st, 1960…" Katrina says avoiding the first question.

"You're a smart girl, now what should I call you? A nickname perhaps you go by?" Pomphrey pushes.

"My friends… they… they called me Kat before they died." Katrina supplies looking away, Pomphrey looks at her sadly and nods.

"Alright Kat… should we get started?" Katrina nods, and so they begin after Pomphrey gets permission from Dumbledore to do all that needed to be done so long as Katrina agreed. After an hour in which they healed a lot of cuts, burns, infections, and bruises Pomphrey began breaking old bones to set them correctly and healing them moments later with a spell, fixing injury's that had healed incorrectly over the years. After 3 hours of work and a lot of swearing from Katrina they finish. Pomphrey has a house elf bring lunch for them sitting in a chair beside Katrina's bed to eat with her.

"Thank you, for taking care of me… and thinking to fix the old damage…" Katrina says after a few minutes of silent eating.

"Of course not dear, it's not a problem. I'm happy I could help you Kat." Pomphrey says nicely. "Now why don't you finish up and if you're feeling well enough I'll call Professor Dumbledore to come have that chat with you. If not then he can wait until you've rested." Katrina stares at her and quickly eats the rest of her food.

"I'd like to talk with the professor Madam." Pomphrey laughs and shakes her head, heading to her office a few minutes later she returns Professor Dumbledore in tow. He smiles at her over his half-moon glasses taking the seat Pomphrey had left.

"It's good to see you awake, you gave me quite a fright when you sent your Patronus to find me last night." The professor says his blues eyes looking her over seriously. Katrina looks down at her hands.

"I was too weak to open the doors… it was all I could think to do sir." She explains truthfully. Dumbledore nods stroking his beard.

"You obviously know who I am and came to us for help… would you please tell me your name and what happened to bring you here child?" Katrina bites her lip glancing back up at him and nods.

"Death Eaters attacked the orphanage I lived in… They killed everyone. I'm the only one who made it out. I came here because I needed to get away. I knew their leader was afraid of you, that they would never follow me here."

"Miss Hannigan's Orphanage I presume? I was called not long after you arrived to help the Aurors look for survivors."

"Yeah that's the one… did you… did you find anyone?" She asks already knowing the answer.

"I'm sorry, we did not." Katrina closes her eyes taking a deep breath trying to keep from crying, even after so many years she would never stop missing the friends she lost that night.

"My names Katrina Rowena Potter, my friends called me Kat… like the animal but with a K instead of a C." She explains staring at her hands but glancing at the two of them every few seconds. Dumbledore and Pomphrey look at each other shocked.

"Potter? Do you know who your parents where Katrina?" Dumbledore asks slowly.

"Yeah, Edmund and Amelia Potter… why?" She asks as if confused. Dumbledore stares at her then stands.

"If you are who you claim to be then you my dear, have an Uncle, Aunt, and Cousin who I am sure would love to take you in. Poppy do you have any vials of parentry potion we could use?" Pomphrey nods going to fetch it and a large piece of parchment. "Now Katrina this potion will show us your parents name, all we need to do is put a drop of your blood in it then dump it on the parchment." He explains to the shocked girl.

"I… I might have family? A Real living family? Why didn't they ever come find me? If they want me why was I sent to the Orphanage when my parents died?" She asks her voice growing louder into a yell then breaking at the end as she forces back tears and anger.

"My dear child they don't know about you. Edmund Potter disappeared years ago… Your uncle, his brother, searched for years but never came up with any leads. I can't promise you that you have a family until we know for certain who your parents where." He takes her hand holding out his wand asking her with his eyes if my take some of her blood. Katrina slowly nods tears sparkling in her eyes. He pricks her finger with a spell and drips a few drops into the vial before closing it and shaking it waiting for the clear liquid to turn Red, before dumping it on the parchment where it immediately soaked in. Katrina's name appears then two lines leading up to two names, Edmund and Amelia Potter. "I'll go fire call Charlus and Dorea then." Dumbledore says standing and heading to the office. Katrina stares at the parchment then after him.

"Is he getting my family?" she asks Pomphrey quietly not daring to hope that it would really be them. Pomphrey nods smiling at her.

June 22nd, 1975 – Potter Manor

James was bored, Sirius and Remus couldn't come to visit until July, and Peter couldn't come all summer. He was bored and a bored Potter is never a good thing, especially a bored 15 year old Potter boy named James. He had pranked 3 of the house elves, his mother twice, and was bored again sitting upside down on the sofa in the main sitting room. He startled when the fire flared Green and Professor Dumbledore's head appeared. He falls of the couch with a thud and rushes over straightening his glasses.

"Professor Dumbledore! Why are you calling?" He asks worriedly wondering if someone he knew had been attacked.

"Mr. Potter, I hope you are enjoying your summer and not causing too much trouble for Dorea?" Dumbledore smiles the twinkle in his eye. James grins knowing it can't be bad if the professor was joking.

"I'm doing well; you know doing homework and being a perfectly well behaved son." He grins at his professor with a wink. Dumbledore chuckles.

"I'm calling for Charlus and Dorea if you wouldn't mind getting them?" James nods jumping and going to the door of the sitting room and yelling.

"MOM, DAD, DUMBLEDORES ON THE FLEW AND WANTS TO TALK TO YOU!" then turning and dropping down nest to the fireplace again. A few minutes go by in which James and his professor chat, before Dorea Potter comes in her brown hair speckled with grey following out of the bun atop her head her robes speckled with dirt from her garden, Charlus follows behind his wild black hair and glasses making him the carbon copy of an older James.

"How can we help you today Albus?" Charlus asks smiling pleasantly.

"Charlus… I have come upon the knowledge as to what happened to your brother Edmund." Dumbledore says softly. "If I may step through I'll explain." The smile falls from Charlus's face as he nods pulling James back so the Professor can come through.

"I want to stay and hear." James says before his Mother can send him off.

"Let him stay he deserves to know too Dorea" Charlus says taking a seat on the couch. She sighs.

"Alright but no joking around… sit down" She tells her son taking a seat beside her husband, James sitting on the arm next to Charlus. Dumbledore sits down in an armchair facing the family.

"Edmund married sometime before May, 1960. On May 21st, 1960 Edmund and his Wife Amelia had a Daughter." Charlus stares at him.

"I have a niece?" Dumbledore nods before continuing.

"I don't know when or how but sometime between then and now Edmund and Amelia died, their Daughter was sent to a Muggle Orphanage. Yesterday evening Death Eaters attacked and killed everyone in the Orphanage, except for one girl who escaped and came to Hogwarts. I found her on the front steps passed out, she sent her Patronus in to get me. I took her to Poppy and she fixed her up, when I went to see her about 40 minutes ago she told me her name and who her parents had been, Poppy and I did a Parentry Potion, Charlus… She is Edmunds Daughter." He explains. James stares at them all in shock looking between his Parents and Headmaster.

"So he's dead… but my niece is alive? Is she okay? What's her name? How old is she?" Dumbledore smiles at the string of questions raising a hand to slow him down.

"Poppy healed all her newer wounds and re broke and healed old wounds that hadn't healed properly. She should be alright although she has been through a lot and is upset, she fought Death Eaters and watched everyone she knew die last night Charlus… until I told her she had no clue she had any family." Dorea wipes a tear form her eye shaking her head.

"The poor darling she would only be our James age… to have gone through so much…" James gets up and goes to sit by his mum taking her hand in comfort. She smiles down at him and squeezes his hand.

"She is 15, the same age as James; if she knows the material then she could join his year at Hogwarts in September." Charlus and Dorea nod.

"We'll have to give her some tests to find out her level…" Dorea says thoughtfully.

"Albus what's her name?" Charlus pushes.

"Her name is Katrina Rowena Potter, or as her friends called her before… well you know, Kat…. Like the animal but with a K instead of a C." He says smiling amusedly. Charlus smiles.

"Katrina… Can we see her Albus?" Dorea asks hopefully.

"Of course… in fact I was hoping you would want to take her in as she has nowhere to go and you are her only living relatives that we know of." The two Potter adults look at one another having a silent conversation.

"We would love to take her in… so long as James is okay with it?" Charlus finally states looking at his son.

"Of Course I'm okay with it… she needs a home! And She's my cousin I want to meet her and get to know her… plus if you took her in wouldn't she be… like my sister?" he asks rambling. Dorea laughs shaking her head,

"Oh my sweet boy…" she hugs him close. "Yes she would be your sister if we adopted her, but your cousin if we just took custody of her."

"You should adopt her, then if someone tries to fight you having her they can't take her away. We don't know about her mother's side or if anyone would want to hurt her, so we have no way of knowing if anyone would try, but safer is better than sorry." Dumbledore suggests.

"So I'm getting a sister?" James pushes looking at his parents. They look at each other, Dorea smiles and nods.

"Yes James, it seems you are getting a sister." Charlus says smiling at his family proudly.
