A/n: So I am finally going to complete this story with a number of new chapters! *lets off confetti*

Thank you to everyone who left lovely reviews even when it looked like I had abandoned our switched up pair for good.

I have made a few minor edits to previous chapters, but main plotlines etc. remain the same.

Just a little idea that I've been thinking about for a while and finally decided to write.

I know first person stories sometimes don't translate so well, but for the purpose of mine it seemed the easiest way to go.

World - Post-war, AU

Hermione

"Oh my God''.

I froze, staring avidly at my reflection in the mirror.

This was a dream. This had to be a dream. No need to start panicking or letting my imagination run away with itself.

I squeezed my eyes closed, breath coming in ragged gasps despite of myself. Just stay calm, Hermione. Whatever this was there would be some reasonable explanation.

But what I'd just seen – the sheer impossibility of it, the complete abandonment of all logic – was overwhelming.

It couldn't be happening; it was rationally and anatomically impossible.

Yet my voice had sounded strange – rougher, deeper…

I opened one eye again, cautiously, and let out a squeak as the same unnatural sight met my eyes. My hand rose involuntarily to touch my cheek, a thrill of dread rushing through my veins as I felt the smooth skin under my fingers.

It was real. Draco Malfoy was standing in my room, in the exact spot where I should be.

Holy fucking Merlin.

I broke out in a cold sweat as my brain caught up with my body, coming to the frankly horrifying conclusion that by some feat of magic as yet unexplained I had turned into Malfoy.

My mind whirred feverishly, going through a myriad of possibilities of who or what could have done this. I hadn't drunk polyjuice potion, I most certainly hadn't been messing around with self-transfiguration. A curse seemed like a plausible option, but when would somebody have had the opportunity to cast it? And it would have taken highly advanced magic, most students at Hogwarts wouldn't be capable of something like that…

My chest tightened as a new thought struck me. If I was Malfoy, then did that mean there was a chance, however small, that he was me?

An ice cold numbness spread up my spine. The thought of Malfoy wandering round school in my body was something that didn't bear thinking about.

I shivered convulsively and hurried out of my room intent on finding him, not realising in time that navigating a body that was a good seven inches taller than my own meant that you had to duck under some doorways.

Fantastic. Now I was Malfoy with a headache.

Draco

A loud, impatient hammering dragged me into consciousness.

I mentally cursed the person on the other side of the door, opening a bleary eye to look at the clock. It was 7:30.

Groaning, I rolled over and tugged the pillow over my head. There was no way I was getting up this early, whatever the emergency. It was a Saturday for fuck sake.

The knock started up for a second time, more incessant than before.

Eventually it reached the point where I couldn't stand to let it go on any longer. Pushing the covers away, I got to my feet and staggered to the door, ready to deliver a torrent of choice obscenities to whoever it was that had disturbed my lie in.

I pulled the door open, but barely had a chance to open my mouth before someone with oddly familiar blonde hair crashed into my chest, bundling me backwards into the room. I started swearing, but the words caught in my throat as I realised who my assailant was. It was me…

"Shit!" I yelled, leaping over the bed in an attempt to put as much space between me and my double as I could. I then practically fell over in shock as I heard the sound of my own voice. I was shrill.

"What the fuck" I whispered, clutching my throat and staring wildly at the seemingly perfect vision of myself. I must be losing my mind. I was hung-over, granted, but this had never resulted in hallucinations before.

"Draco?" The apparition asked in a hysterical squeak I didn't know I was capable of.

"What the hell is this?" I demanded, horrified all over again as it came out as a high pitched shriek.

"Look in the mirror" the thing… me…. replied in a hollow whisper.

I strode into the bathroom, not entirely sure I should be taking instructions from it but keen to find out what was going on. The other Draco followed close behind me with a frightened expression that I sincerely hoped hadn't been on my face since I was three and the stupid albino peacocks at Malfoy Manor had attacked me.

The image that greeted me in the mirror made my blood turn cold. It was literally the last thing in the world I would have expected and more disturbing than I could ever have imagined. Long brown hair, chestnut eyes and an alarmingly voluptuous figure; I was looking at an utterly dismayed reflection of Hermione Granger.

For the first time in both our lives, words failed me.

"We've switched" the other Draco croaked, biting down on his bottom lip in a way that was achingly familiar...

"Granger?" I moaned, the realisation hitting me like the Hogwarts express. "You're me?"

Surely that didn't mean I was her? Not just a girl, but goddamn Granger of all people. I realised I was shaking my head.

And she was nodding in an infuriatingly knowing way, the same thing she did in lessons when a teacher explained something complex that nobody else understood.

"And I'm you" she agreed.

I stared at her in appalled silence.

"Why?"

"I have no idea''. Hermione seemed to abruptly find that she was very angry and very articulate. "But this kind of thing could only be achieved through powerful dark magic, and out of the two of us, I think you're the one who is slightly more clued up on that front. Look at your family! This kind of prank smacks all over of a Slytherin who thinks they're being funny but is actually just immature and dangerous''.

She folded her arms and surveyed me sternly. It was the strangest experience being told off by myself and I was slightly taken aback until I realised what she was getting at.

"You don't think I did this?" I retorted indignantly. "Why the hell would I want to be you? I can't imagine anything worse''.

"Well I certainly didn't do it!" Hermione snapped. "And I'm not exactly thrilled either''.

I gaped at her, all of my incredulity suddenly replaced by frustration. "At least you get to be me! I definitely got the worst end of this deal. I'm stuck being a frizzy haired mudblood''.

"Oh that's rich!" she flared up. "Because you're so wonderful are you? An obnoxious, egotistical ferret!"

Without warning, there was an ear splitting bang and a dazzling flash of gold seared across my vision.

"Ahhhh!" I yelled, diving across my bed for the second time that morning. It was starting to become rather undignified.

"Fawkes!" Hermione gasped, gazing in astonishment at the great amber bird that had just materialised in the room.

Well that was just typical. Granger was on speaking terms with the phoenix.

Picking myself up from the ground with as much poise as I could muster, I watched as she went over and began stroking Dumbledore's pathetic pet.

"What does it want?" I asked, not attempting to keep the disdain from my voice.

"It's a letter from Dumbledore" she said in surprise, unrolling the piece of parchment that she had taken from the bird's beak. I strode across to her and began reading the thin slanted script. Even in the stress of the situation the irony didn't escape me; I was reading over my own shoulder.

Dear Miss Granger and Mr Malfoy,

As you are aware this year you attained the positions of head boy and girl, and, as I am also sure you are aware, (being two of the brightest students in the school) you have swapped bodies.

What I am about to reveal to you is a Hogwarts tradition, one, though highly weird and wonderful, is not to be taken lightly. This switching of persons is a challenge which is supposed to teach you the values of leadership, tolerance, determination in the face of adversity and an insight into a different world. As have generations of head boys and girls before you, you will spend the rest of the term as each other, attending respective classes and attempting, as much as possible, to fit seamlessly into the other's life.

You are forbidden to tell anybody else of this change and if you endeavour to disclose the information in this letter, then you will find yourself unable to speak until you have decided to conform. These may seem stringent rules, but they are necessary for the full learning experience, and after a term I am certain you will agree that it was worth it.

Hoping you are well and with my best wishes for the forthcoming term,

Professor Dumbledore

By the time I had finished reading the letter, everything had started to seem slightly less horrifying and struck me as having the potential to be comical (yes, it was still deeply disturbing, but being a Slytherin meant that you developed a degree of immunity to messed up situations).

I turned to look at Hermione, who was visibly seething, and began to laugh. Now I knew this wasn't a permanent change, I could see that there might be some advantages to the switch. This could be entertaining. Or, if you preferred to look at it the other way round, deeply uncomfortable for Granger...

"How can you find this funny!" Hermione demanded, her eyes glittering dangerously. "We're stuck as each other for the rest of term! The rest of term, Malfoy! What about NEWTS?"

"Don't worry" I smirked, pointing at a line in the letter, "it says we'll still be going to lessons. Just you'll be a Slytherin and I'll be a Gryffindor''.

"But this is insane! What could Dumbledore possibly believe we would gain from switching?"

"Now think Granger, did you ever express the desire for a penis in front of him?" I drawled.

"You are unbelievable!" she snarled, turning on her heel and storming out of the room. I sauntered after her, confidence restored. This was the kind of thing I could deal with; Granger incensed and me being the one who had pissed her off.

"Hey Granger, where are you going?"

"Away from you. You are impossible!"

I sped up so that I was ahead of her as we reached the doorway that led out of the heads dormitory. "You can't go out you know''.

"And why ever not?" she replied crossly, attempting to shove past me to the door.

Frustrated, I grabbed her by the wrist and pushed her back against the wall. She looked up at me and it dawned on me that in my body she could easily overpower me. Thankfully this didn't seem to have occurred to her yet and she didn't struggle as I stared stonily up at her.

"Because I don't go round throwing hissy fits, and the minute you leave here, you're not Hermione Granger anymore, you're Draco Malfoy. You'll screw my life up''.

"And why shouldn't I screw your life up?" she said quietly, meeting my gaze with a vicious expression on her face.

"Well, quite aside from wanting to please your precious Dumbledore and stick to the rules he created, I could just as easily fuck yours up Granger. And what's more, I'd do it better''. I released her wrists and threw her a cold look as I turned to walk back to my room.

A few minutes later, she joined me. Her rage seemed to have dissipated as quickly as it had come and she wore a weary expression. She slumped down against the wall, wrapping her arms around her knees.

"Bugger''.

"You're bloody right" I muttered, more to myself than to her (I wasn't about to agree with any sentiment a Gryffindor had made). If she went round in my body having tantrums and generally being her usual sanctimonious self, my reputation would have a hard time recovering. It wasn't a question of messing around with her life anymore, it was making sure she didn't completely destroy mine. If I wanted to get through this year with the title of prince of Slytherin still intact – not a title I'd selected for myself, but I wasn't complaining – then she would have to undergo a rapid Malfoy crash course.

"Hey Granger" I said, softly this time. "We can do this, alright? All we need to do is act like each other. Just don't ponce around crying, ok?"

She sniffed. "So what are we going to do?"

"We'll fit flawlessly into our new lives. You tell me everything about you. I'll tell you everything about me''.

Hermione raised an eyebrow and in that instant her expression was exactly one of my own. "Everything Malfoy? Do I really want to know every single detail of your squalid sexual encounters?"

I grinned, the future looking considerably brighter. "It'll be the hottest thing your innocent ears ever heard''.

Hermione blanched.
