Rejuvenation - Chapter 1

"Harry mate, you finished? Only we've got to go."

Go? Go where? Harry glanced over from the piece of parchment he was reading to the large Grandfather clock situated in the corner of his office. 6.25pm, he was working a little late again. At least with the kids at Hogwarts he didn't have to worry so much about his timekeeping and he had more flexibility with when to book appointments.

Appointment.

"Oh shit! Sorry Ron, I completely forgot!" Harry quickly grabbed his quill and signed off the report in his hands. "I'll just tidy up a bit and I'll be ready to go. It won't take a minute, promise."

"It's fine." Ron said dismissively.

Harry shuffled and tidies quickly, making sure he sent off the last of his memos, which Ron helpfully held the door open for. Grabbing his wand Harry cast the few locking and security charms on his desk drawers and the filing cabinets. That done all he had left to do was grab his robe and he was good to go.

"Right all done. Sorry about that, it's been rather manic today and I lost track of time."

"It's alright mate, it's not the first time."

No, no it wasn't the first time, Harry sighed. He was always losing track of time, even before he took over as Head of the Aurors he had lost track of time because of one case or another. Today it had been paperwork and piles of the stuff. Why was it when you employed somebody there were only a few little bits of paperwork? But when you fired somebody you had to fill out whole stacks?!

Stupid bloody Tenderfoot! Even after 2 warnings and a disciplinary he hadn't mended his ways. And, granted, Tenderfoot had been working on a case which, as it turned out, was a lot more than it appeared to be, but still!

"So…" Ron started then trailed off as Harry locked the door to his office.

"So what?"

"So, you want to tell me what got you in such a mood earlier?"

"I don't know what you mean." Harry reflected feebly, the lie completely obvious to anyone within hearing distance.

"Come on mate." Ron coaxed and Harry sighed, caving in under the miniscule pressure. He needed to vent; really, really needed to vent.

"Alright, let's just get out of here first." Harry said and sent a glare to the other aurors who had decided to stay on late but had all paused in their work to watch and listen to Harry and Ron. They all quickly averted their eyes when Harry glared at them and went back to work. Harry felt slightly mollified. Slightly.

He and Ron walked through the Ministry and down to the floo area. Thankfully not having to queue for long Harry and Ron landed in the waiting room at St Mungo's for their Quarterly check-ups. Because he and Ron had joined the auror's at the same time their appointments always coincided with each other's so they always went together; 4 times a year for the last nearly two decades.

"Names?"

"Aurors Ronald Bilius Weasley and Harry James Potter. We have an appointment." Ron offered to the Welcome-Witch who didn't even spare them a glance until after she had checked her piece of paper.

"I'm afraid, due to the outbreak of Scrofungulus, your appointment room and healer has been changed. You will now be seen on the First Floor by Healer Wollaston in exam room CL7."

"First floor? Creature Induced Injuries?" Ron asked sounding sceptical. The welcome witch peered at him over spikey-cornered crescent moon spectacles.

"Yes. You will find the healers there are just as capable of performing the Auror health checks as anywhere else."

"I wasn't questioning that…" Ron shifted a little uncomfortably. Harry decided to turn the witch's attention from his friend and onto him instead. He never really understood why they were called welcome witches, none of them ever seemed very welcoming.

"Do you need the auror's help to help keep a quarantine?" He asked and those sharp eyes turned to him.

"Not at this present moment in time Auror Potter." She said sharply then turned back to her parchments on her desk. Harry took that as a dismissal and slapped Ron on the back as they turned to walk towards the elevator. A portly man joined them in the elevator, sporting a flat cap, tweed jacket and bright red jeans. He smiled and nodded at them, his chubby cheeks turning white under the strain of the smile because there was a lot of flesh to move to create the smile. Harry returned the smile with equal humour, not because he felt happy but because the sight of the man's moustache was rather amusing. In fact it looked like one entire side of the man's head was bald, completely and utterly bald. There were no pore marks or stubble, no eyebrows, no moustache and no nostril hair on the left side of the man's face. The right side however sported a bushy eyebrow, full moustache that extended around the corner of the man's mouth, and a thick sideburn leading up to mouse-blonde hair beneath the man's cap.

"Hello there Auror Weasley, Auror Potter. Beautiful day out there isn't it?!" He asked, his broad Yorkshire accent wavering around the enclosed space of the elevator.

"Yes, perfect barbeque weather and it's only March." Ron offered and the man grinned more and bounced once onto the balls of his feet.

"Yes it is that." The man said and pressed a large finger into the number five, the doors slowly closing. He must have seen their questioning gazes because he wiggled his nose, making his moustache move, and grinned. "They've got banana cake in today."

"Ah I see." Harry offered and nearly rolled his eyes. Of course the man would think about food. "So you came to St Mungo's for the banana cake?"

"Oh no!" Those beady eyes widened with alarm. "Oh no I'd never risk coming here just for the banana cake. No, I had a bit of trouble with a cursed shaving set I picked up from a street vendor yesterday. It took off all my hair you see and a bit of skin along with it. Sliced my nostril right open. I had to go to magical artefacts to get the thing out of my nose. They healed me right up, took all day but I had to grow some new skin you see. After it was done I heard somebody talking about the wonderful banana cake in the tearoom and, well, I can't resist a bit of cake."

The elevator came to a halt and announced they were on the first floor. It took another moment for the doors to begin to open but Ron and Harry shuffled forwards closer to them anyway.

"Ah well, sorry to hear about the problems you had. I hope to see you in the Auror department tomorrow filling so we can start an enquiry." Harry said as he stepped out into the hall of the Creature-induced injury ward.

"Ah right you are Auror Potter. I'll be right along there tomorrow." The man waved cheerfully as the doors closed and blocked their view. Seconds after Harry saw the lift continue going up through the numbers. Old habits had him wait to see if the man was indeed telling the truth that he was going to the tearoom. As the pointer came to a halt at the number 5 Harry laughed to himself and rolled his eyes. So suspicious of everyone still, even after all these years he never wholly trusted people's word.

"Come on then Harry, don't want to be late."

It took a few minutes but eventually they were lead into exam room CL7 to wait for the healer to arrive. The medi-witch had seemed surprised that Harry and Ron would wait in the room together and have their examinations at the same time, but she dutifully acquiesced to their wishes and showed them the way. The room was plain, boring and white. Ever so, ever so white. The only splash of colour was a lime green soap holder by the sink and a lime green robe that hung on a peg in the corner. Otherwise everything seemed to be white, or very light shades of grey. Boring, achromatic shades.

"So mate? What happened today?"

"Oh Merlin what didn't happen today?" Harry groaned and sunk heavily into the chair provided. It was an uncomfortable, squeaky white washed wooden thing that dug uncomfortably into his spine and his shoulder blades. "I had another report of a hag being arrested from Tenderfoot which was fine until I saw that Urquhart had interviewed a woman who came in claiming her husband had gone missing. When I went out to check with Urquhart about some mistakes in the report he'd given me I caught Tenderfoot bragging that he'd caught yet another Dark Creature and that he was single-handedly saving the world from them. I could have dismissed that as typical bragging and boasting but Ellison asked whether Tenderfoot had found any of the disappeared children he'd been looking for. Tenderfoot laughed and said no, there was no need to find them because obviously the Hags had eaten them and there would be no evidence. Ellison asked if he had evidence to suspect that the Hags ate the children and Tenderfoot laughed again. Apparently he 'doesn't need evidence, they were hags'.

"I know I was instructed by human resources and the disciplinary board to give him more responsibility so that he got less 'bored' on the job but I'm sorry, his commitment to the aurors and what we stand for just isn't there. He had made no progress on his cases and his attitude was horrific. He was failing to do his job, dismissing important cases, falsifying evidence, giving false information to family members and using his position to go on a personal vendetta against dark creatures. Since it was his third offence I fired him. I've spent the rest of the morning and most of the afternoon sorting out the paperwork regarding his termination of employment, then the rest of the day sorting through his cases. I'd only just finished it and started on the day to day business when you came in."

"Blimey mate. So Tenderfoot's gone?"

"Yes! And gone for good!" Harry said adamantly. "I don't care what human resources throw at me or the Law Department. I've got enough evidence to send him to Azkaban for a few months. The way I figure it he's getting off easy."

Harry's mouth drew into a grim line. He couldn't believe how horrendous the Tenderfoot situation had gotten, and how long he hadn't noticed. Two weeks was a very long time, especially in missing people, and more specifically in missing children cases. And not only that, but when Harry had seen the case files he had immediately been reminded of similar, more sparse, reports of missing children and had tracked those down too only to find they were the same MO.

"It was all in shambles Ron. It took me only five minutes of reading through the reports of the missing children to notice there were similarities to older, unsolved cases. Granted Tenderfoot couldn't be expected to know that because he's reasonably new on the force, but even in the five years he has been working there he should have picked up on the fact that those missing children reports were the same as the Trengove case two years ago and the Howard case four years ago. It wasn't a hard connection to make. He just couldn't be bothered to make any connections, didn't want to look for them and didn't want to find them. He just wanted to track down Dark Creatures and this was a convenient excuse to go after Hags."

There were a few minutes of silence before Ron broached the topic again.

"So what's happening with his cases now?"

"I've given them to Frost. He's at the top of his game at the moment and we really need someone with that expertise." The door to the exam room opened and in stepped a healer in the usual bright lime green robes carrying a scroll of parchment. Harry decided to quickly wrap up the conversation. "Frost has submitted an excellent list of people to work in his team to solve the case and I've approved each and every one of them. But I'd like you to work with them too Ron please. I have a feeling that this case is a lot bigger than we think it is right now. I want those children found and putting you with Frost's team insures that."

"Right, so no pressure then mate." Ron joked and Harry laughed with him.

"Right then Auror Weasley and Auror Potter. I am Healer Wollaston. Just the routine Auror health checks today then?" Healer Wollaston had a mass of fluffy hair that looked like white candy floss had been stuck down on the pale skin. Two crystal blue eyes shone out amongst the mass of wrinkles surrounding eyes, nose and mouth. Old didn't quite cover Wollaston. A slightly hunched back, careful rickety legs and a very slight tremor to the left hand. Still, there was a patient smile, a glimmer in the bright eyes and a relaxed air about the healer.

"Yes sir." Ron said and cracked his knuckles.

"So which one is going first?"

"I will."

"Urgh Harry!" Ron whined, Harry just grinned at him and got up from his chair to move over to the examination table. He pulled himself up onto it and began undoing his shirt ready for the spells that would require no fabric between them to work properly.

"Do I have your permission to cast spells upon your person?" Wollaston asked, moving around the bed to stand on the other side of Harry where Ron could observe his work.

"Yes."

"Excellent! Then let's get started with a simple diagnostic charm shall we, then we shall go a little more in depth. Respice egritudo." The healer said and waved his wand over Harry's head.

A few spells later Harry got asked to put his robe, shirt, wand holster and wand down on the little table so that nothing would interfere with the more in depth heart, lungs, kidney and liver function. Normal procedural things. Harry removed and bundled up his robe and shirt into a messy ball and shoved it onto the table. His wand holster, with wand still in it, went too along with his watch. His wedding band he tossed to Ron who put it inside his pocket with a grin and a pat. Harry rolled his eyes. Yes Ron never grew out of being smug that because he and Hermione had gold wedding bands they didn't have to remove them for examinations because gold didn't interfere with spells. Platinum on the other hand did interfere with spells.

"Excellent. Alright then, we will examine your heart first. Stabilitas cor. Ah excellent, excellent. And onto the lungs. St-ahem hmm ahem. Oh do excuse me a moment Auror Potter." The healer coughed, hiding his mouth from view with his hand. "Ahem hem…oh I do apologise. Old age you know, it catches up with us all."

Harry and Ron laughed along with the Healer who quickly washed his hands.

"Right that's better. And on with the examination. Are you ready?" The healer asked and Harry nodded, settling himself to wait out the next spell. "Excellent. Here we go then. Stupify!"

A red spell shot out over Harry's head and hit a surprised Ron in the chest. Harry threw himself forwards to grab his wand from the table. He slid it out of his holster and twisted all only taking milliseconds of time. By the time Ron's body hit the floor Harry had spun and taken aim.

Only, red light flooded his vision.

Author's Notes: And so we begin another story. I hope everybody read the warnings at the beginning of this fic. This will be a 'gender changing' fic in where some of the characters will be changed from one gender to the other gender. Boy to girl, girl to boy. There will also be torture in this fic, death, human experimentation….honestly, check the warnings. They are there for a reason.

This story mostly came about because how often do we wish we could just go back in time and make changed; like study harder in school, make more friends, make less friends, do different stuff. Then I considered how it would be possible in a Harry Potter story. Having missed writing Henri from Metamorphose I decided to merge the two ideas and for a new story. Thus, female Harry again eventually and also a step back into youth. It should be an interesting ride. I hope you continue to read and enjoy it with me.

As always you can expect irregular updates. Sometimes you won't hear from me in two weeks maybe even a month, sometimes I will fire out three chapters in a day. It all depends on the chapters and whether I have written enough in advance. I am currently at 60000 words for this story and have sectioned out 14 chapters so you will get those assuming I am still writing about 10 chapters in advance of what I post...if that makes sense.

I hope to hear from you all soon. Happy reading!
