Chapter Two

As we waited, I couldn't help but wonder once again why Luna seemed so interested in wanting this to work. With nothing else to do after several minutes had passed, I finally asked her.

"Luna, why is it so important for you to be able to make the transformation last longer than the usual hour?"

She looked deep in thought, and appeared to be pondering whether she should answer me. After a few moments Luna seemed to decide I was worth the risk. She turned to look me straight in the eyes.

"I'm sure by now that you have noticed that as far as girls go, I've always been a bit different. I've never been one to be very concerned about how I look. Things like clothes, make-up, or boys have never been a big deal for me. Not being very interested in those sorts of things, tends to make one rather unpopular with other girls. I'm not very pretty or very feminine. The only boy I have ever been interested in, has never thought of me as anything more than a friend. I've often thought that my being born a girl must be some sort of mistake. Because I don't really think or act like one. I thought that if this works, I might one day be able to correct that mistake," she concluded honestly.

I guess I shouldn't have been surprised by what Luna said, but I was. It never really occurred to me that a lot of what made Luna different from other girls was because she felt that she was born the wrong gender.

"Take it from me Luna - many times I have wished that I was someone else. And not the famous Harry Potter. But I can tell you from personal experience, that being Harry Potter is way overrated," I told her seriously.

"I suppose you have a point. But how many girls have you known that weren't interested in clothes, boys or wearing make-up?"

"Only one. But that doesn't mean it's wrong not to be interested in those things," I protested in response.

She then seemed to give what I said some serious thought. And then it suddenly hit me, the rest of what Luna said. There was a boy that she liked. I wondered who it could be.

"Who is the boy you like? Perhaps I could give him a little push. Or if that fails, give him a slap upside the head," I declared, gesturing with my hands.

She looked again like she was trying to decide how to answer. But just like before, she seemed to think I might be worth the risk.

"Are you sure about that?" she asked playfully. "Because you'd look pretty silly hitting yourself in the head." She gave a smile that made me realize just how pretty she could be.

And then it sunk in that it was me that she had her eye on. I had to say that this really shocked me. I had never got the impression that Luna liked me as more than a friend. In fact, I never got the impression she was fond of anyone like that.

"It's me that you like? Really?" I asked, still finding it hard to believe.

"Who else would I actually go through the trouble of actually wearing a dress to Slughorn's Christmas party? I even brushed my hair and wore a little make-up. Ask yourself, have you ever seen me do it before or since then?" she asked with her arms folded, looking rather annoyed.

Of course she was right, that was the only time I've seen her in a dress. Well - other than Bill and Fleur's wedding. Poor Luna, I guess she really did make an effort. It's just too bad that I was so useless at noticing things like that.

"I'm sorry Luna, I guess I should have realised. But like most guys, I was completely clueless about such things," I said in my defence.

She nodded, placated. "I guess it was unfair to expect you to notice me, when you only asked me to go with you as a friend."

"I'm sorry Luna. My track record with girls, hasn't been very good," I pointed out.

"Maybe you would be more successful in a relationship if you were the girl." She smirked.

"Who knows - maybe you're right about that. But if it makes you feel any better, I was thinking about asking you out to this weekend's Hogsmeade visit," I replied hopefully.

"You do realize that if this works, and we went on a date - you'll be the one who's the girl," she declared, with a cheeky smile.

I must admit that the timing of Luna's last comment seemed to have been timed just right. Because at that exact moment, I felt the now- familiar tingle, and my body once again began to change. It would seem that Luna's theory was correct after all. And I was beginning to change back into her form. But somehow this change was different than all the other transformations up to now. It even felt completely different, even though at the time I may not have understood why that was at the moment. It was because this time I wasn't just transforming back into Luna's shape, my body was actually being changed into an exact duplicate of hers in every way. Because apparently that's who the Polyjuice potion thought I really was.

I thought that this time I should really pay more attention to the transformation. And what it was like to change into Luna again. The first thing I noticed as I shrank in height, was that I had to look up at things that before I didn't. Not a lot mind you - but enough to notice the difference. Next, my hair grew longer in the front and back while changing from my normal black to Luna's pale blonde. I then saw my hips and waist taking on the feminine curves of a young woman - and it struck me that I was, in a sense, experiencing a girl's physical transition towards womanhood, only much faster than normal.

As I continued watching, my hands, feet, and limbs lost mass - even as Luna, in turn, gained it in hers. The span of my shoulders narrowed, my throat seemed to deflate somewhat - and two soft, fleshy mounds started to push out from my chest again. I couldn't believe it - I was actually growing my own pair of breasts. At the same time, I felt my male equipment deflating and shrinking almost to nothing, as the bulge at the join of my trousers became smaller and smaller, until I was now as flat between my legs as any other girl. I gasped, now paying attention to the sensations as my inverted genitals moved upwards within me - creating a vagina, womb, fallopian tubes, and lastly my new ovaries. As my bodies plumbing completely altered to the female arrangement. Then finally, with a blurring of my vision once more, the all-over tingling faded away. It appeared that my third transformation was now complete.

Shaking a little, I took off my spectacles - passing them to Luna, who now looked like me again. With my sharper eyesight, I looked over my smaller, hairless hands and longer fingernails. My clothes felt looser in some places, yet tighter in others. Mostly tighter in the chest and hips. This wasn't surprising, since my male clothes weren't exactly designed for my newly-acquired female form.

Luna was just slipping on my glasses. He smiled. "That's much better," he announced with his new voice, as he looked over his notes again. He then grabbed his wand and cast a spell. It didn't seem to work right for some reason.

"That's odd." With a confused expression, Luna turned to me and asked, "Could I borrow your wand?"

We traded wands. As I held Luna's wand for the first time, it felt warm and somehow right in my hand. Kind of like how my phoenix and holly wand felt, when I first held it. Like it should belong to me. Luna then cast the spell again - but this time with my wand. It apparently worked, because he got the reaction he was looking for. He then repeated the spell on me.

"What spell was that?" I asked, in my noticeably airy female voice.

"It's a spell to check if a person is under the influence of the Polyjuice potion. But according to the results, neither of us are at the moment. Another interesting side-effect is our original wands don't seem to work right for us any more. Do you know what this means?" Luna asked excitedly.

"Should I know what it means?" I asked him in return.

"Don't you see? Our wands sync to us physically as well as magically. And when we changed into each other physically, we apparently also changed into each other magically. If there was such a thing as a spell to magically identify a person. It would probably say that you are Luna Lovegood and that I am Harry Potter. There is no way anyone can tell that we've switched. I never expected the change to be this complete! But the way our wands are working seems to confirm this theory." Luna sounded surprised by this.

Wait I thought - there was a way to check if he was right. I pulled out the Marauders map. It clearly showed both our names. But as Luna paced back and forth, so did the name Harry Potter. While Luna Lovegood remained unmoving. He was right - it was a complete change. As far as any means of physical or magical identification they would all say I was Luna Lovegood. The real Luna came over and looked at the map as well. When I looked up at him, I guess the look on my face revealed my concern that we might not be able to change back.

"Don't worry. There is no reason why it shouldn't work again the other way. I'd do it right now, except another hour will put us well past curfew," he told me honestly.

I'm sure Luna was right. She had been correct about everything else so far.

"I think for now we should remain switched. And stick with the original plan of changing back this Sunday evening" Luna grinned. "For now, we need to swap clothes, wands and names during the time we remain switched. Okay, Luna?"

"Of course, HARRY," I replied, feeling a bit odd about using each others names and changing clothes in front of each other.

"Don't let it bother you so much. We're going to see quite a lot of each other over the next few days," the new Harry declared brightly. "Besides even though it looks very different, that's still your body. Even if it's now in my form."

I guess he was right. How could I be Luna for the next few days and not see this body naked? The only way would be if I didn't shower or change clothes. And that really wasn't practical. But I still couldn't help feeling a bit funny about it. Oh well in for a Knut, in for a Galleon.

"It might even help us to get over it quicker if we see our new bodies naked, while we change clothes. Perhaps in front of a mirror. Here, I'll put a locking charm on the door too." Harry turned and cast the spell.

With that, he also used my wand to conjure a mirror and began to undress in front of it. As I used Luna's wand to cast the spell to conjure a mirror of my own, I couldn't help but feel once again that this wand should be mine. It was a strange feeling to realize this. I looked in the mirror and started to remove my own clothes. I took a moment to familiarize myself with what was for now my body. Who would have thought that under all those clothes that Luna's body was actually this shapely? Not quite an adult woman's, but definitely not a little girl's either. It was clear that when Luna finished growing, that she would be a very beautiful woman. Nice firm round breasts, not too big and not too small. She had nice curvy hips and a lovely narrow waist. The little patch of blonde hair between my legs showed no doubt that Luna was a natural blonde. If she just spent a little time on her hair and makeup, she could be one of the prettier girls in the school.

I took a moment to reflect on what I had physically lost - seeing how flat I was between my legs...

I took a deep breath to calm myself. I am now a witch... But I will be a wizard again by Monday..., I told myself.

"Wow! The summer has been good to you, Harry," the new Harry voiced his approval, looking over his newly acquired form.

"Nothing like being on the run last year, to keep one fit," I replied, being more than a little sarcastic.

He then handed me Luna's clothes and took the pile that I had removed. I noticed that they were still warm. I decided to start with the knickers, I slipped them on over my hips. It was strange for them to feel so flat in the front, where there would normally be a bulge. I then thought the bra should be the next piece of clothing to put on - but it wasn't as easy as it looked. I turned to the new Harry.

"Is there some trick to putting these on," I asked him, sounding a bit annoyed.

The new wizard turned and looked at me with a big smile, as he finished changing into my old clothes. "Are you having trouble, Luna?"

"A bit, how do you manage to hook the clasp behind your back?" I questioned.

"There is a trick I'll show you. But to hook it behind your back, it just takes practice," he answered.

He walked over and said, "Beginners will sometimes put the bra on backwards and hook it first, then turn it back around. Then put your arms through the straps and reposition each breast in the cups by using your hands."

"Like this?" I asked. Doing it as I was instructed. I was a bit clumsy, but I think it would have worked better if my new breasts weren't so big. This technique was obviously meant for a girl, who was just starting to wear a bra, and who wasn't likely to be this far along in breast development.

"That will work for now. At least till you get better at clasping it behind your back," he announced playfully.

I then put on the white dress shirt, buttoned it up. Then stepped into the skirt, while zipping it up after tucking in the shirt. I decided that the silver and blue tie should be next. After that I pulled the jumper over my head, as Harry helped me pull my hair out from under the back of the collar. I then slipped on the knee socks and shoes. After finishing with the robe, I was now fully dressed. I turned and looked in the mirror, and saw a pretty blonde blueish grey eyed school girl. The only problem was, that school girl was me.

Before I banished the mirror, I paused, thinking. I was now in Ravenclaw... I'd have to act smart like Luna, in order to blend in with my new housemates.

"I think it's time we headed back to our common rooms. Is there anything I should know?" The original Luna asked me, tilting his head.

"Um... Yes. Harry doesn't angle his head, when thinking," I pointed out.

The new Harry winced. "Sorry... I'll work on that. In turn, I should say that Luna doesn't 'um' and 'er'."

"Right... Thanks. Anyway, remember the password and that you're in the seventh year boys room, with Ron, Neville, Dean and Seamus. Ron and Neville snore pretty loud. If it gets too bad cast a silencing charm on the curtains, that's what I usually do" I told him.

"What's the password?" the new Harry asked.

"Lions rule!" I replied, smiling.

"Is it really? You're not having me on are you?" he asked doubtfully.

"Nope, they're usually fairly easy to remember," I said. "Does the Ravenclaw entry still ask you a question?" I asked him, a bit worried about what question it might ask.

"Yes it does, do you want me to walk you there? Or do you think you can handle it?" he asked, sounding a bit concerned.

"I think I can manage on my own," I protested.

"Okay. We best get to our common rooms, it's almost curfew."

He then cast a spell to undo the locking charm. I then handed my invisible cloak and the Marauders map after tapping it and saying "Mischief Managed." I handed them to the new Harry.

"You better keep these for now. It would look odd to Ron and Hermione if Harry doesn't have them," I pointed out to the new Harry.

He took them and hid them in his robes. We continued to walked together until we had to split up to go in different directions. I continued up the other stairs to the Ravenclaw tower entry. On the door was the same bronze knocker in the shape of an eagle, I had seen it before when I came here with Luna. So I gave it a quick knock and waited for it to asked it's riddle.

"What is the shortest distance between two points?" it asked.

"A straight line," I answered confidently.

"Excellent reasoning," it replied, as the door slid aside.

I then walked through the mostly empty common room - then headed up the stairs that led to the girls dormitory. I paused a moment remembering that boys cannot go up the stairs to the girls dormitory. But then, I was not exactly a boy at that instant, was I? I continued on and climbed up to the seventh year dorm. Since Luna had attended most of last year and had scored well enough on her tests, she had been able to continue onto her seventh year. There were only four other girls besides Luna - and they were already asleep. It was just as well, I really didn't want to deal with them tonight. So I walked over to the only empty bed by the window. On the bed was Luna's nightdress, I guess that was what she slept in. I then proceeded to undress down to just my knickers. I then slipped the nightdress over my head. Not too bad, at least it was warm. I pulled the covers back and got into bed.

Sleep didn't seem to come very easy at first. It was then that I realised that this time I would remain in Luna's form. Unless we again used the Polyjuice Potion to reverse the transformation. Until then, I was Luna Lovegood. Part of me was looking forward to this. Because, for the first time in my life, I didn't have to be Harry Potter. And there was no way anyone would know it. This was my final thought, as sleep finally claimed me.
