Fire and Ice

By DarkLordMist

A/N: So I read my fan-fictions today and I found out that they had nearly no plot like J.K. Rowling's or any good writer would put on. There's not much suspense or excitement or action in any of my stories, a lot of it is like some pointless day-by-day thing.

Therefore, I decided that for your enjoyment I have another fan fiction for you all that I hope you will enjoy… and believe me I'm really working to become a better writer

Summary: AU Harry and Blaise (girl) have been enemies since day one, and now seven years later they are head boy and head girl. The Gryffindor-Slytherin rivalry is the most intense ever, as the bitter rivals struggle to win their last House and Quidditch Cups.

Disclaimer: I don't own any of the characters, or the setting, but I do own the plot.

Chapter 1: That crazy insane old codger

Harry Potter, seventeen-year-old wizard sat down in anticipation as he waited for his best friends. He couldn't wait for the last school year to start…

"Hey mate! How are you?" greeted Ron as he entered. He smiled at Harry, who smiled warmly with a "Hello!"

Ron Weasley had grown up to be a tall, 6 feet and a half 17-year-old who was taller most people in the school. He was also Harry Potter's best friend, and had supported him through all the seven years…

"Harry!" cried Hermione happily as she entered the compartment.

Hermione had grown a lot during the past seven years. Her bushy hair had eventually gave out to a sleek, brown hairdo. Her figure had laid out quite nicely, and her face had aged beautifully. But Harry didn't think those thoughts about her anymore… ever since last year…

She hugged Harry, who began to choke on his red-hot spicy pepper jelly bean.

"Ughhh- cough cough wheeze hey Hermione!" croaked Harry with tears in his eyes. The red-hot spicy pepper jelly bean does wonders to one's throat.

"So, did you guys finish the summer homework? Please tell me you did. Oh, I hope I'm Head Girl this year! It's going to be so exciting, our last year at Hogwarts... but I think I'm going to become a teacher here later, this castle is absolutely magical for me, oh, I love it so much! And the N.E.W.T.S are this year too, you guys do know that it's very important for your survival in the wizarding world, we have to start studying now! So let's review over the Transfiguration spells you researched during the summer which I hope you guys do know it was your homework, OK? Alright, what was the-"

"Yawn" yawned Ron.

Great, thought Harry, two minutes into meeting Hermione and we're already on the N.E.W.T.S.

Hermione glared fiercely at Ron (who winces under her glare…) "You do realize how important this is?! Oh my god, you guys better do good on the N.E.W.T.s! If you don't, then all your 7 years at Hogwarts will be wasted! Come on Harry, you agree right? This is most likely the single most important event of our Hogwarts experience!"

Ron rolled his eyes. "Tests are all you think about, Hermione! Would you please get your head out of your arse and think about the fact that this is our last year as students, our last year to do whatever we've always wanted to do but never had a chance to do?! This is our last year, and we have to make the most out of it, Hermione! Like, pull pranks on the Slytherins, sneak to the Kitchens, raid the girls dormitory- oh sorry, Hermione…"

Hermione glared at Ron. "You're so immature, Ron! But it's OK, because for all I care, you can go fail your tests and become the driver of the Knight Bus, but I, I will do good on these tests and… and…"

Ron smirked triumphantly. "You don't even know your future! Great bookworm you are! Oh, I thought you would already be saying that you'd be the next Minister, or Ministress, of Magic, or the Headmaster, I mean Headmistress of Hogwarts, or the oh, I don't know, some Order of Merlin first Class winner or…"

"Yeah, well, you can't even tell the difference between a male and a female! Some Headmaster I'll make! Yeah, I think I'll go change my gender right now, Ron! And I do know my future, because I know that I'm going to have much more prospects than you! It'll be your loss to fail these tests, your loss to destroy the rest of your future, only because you want to play!"

Oh great, thought Harry with exasperation, five minutes into the train and we're arguing like 5 year-olds.

"Well, remind me how important the tests are after Easter Break, please! I don't want to think about them now!"

Hermione sighed, threw her hands up into the air (in exasperation or defeat, but Harry can't tell…) and sat down, plopping open the book of N.E.W.T.S. Level Transfiguration: The Mastery of Transforming.

Ron sighed too, sat down, and grinned at Harry. "Harry, mate, wonder who'll be the Head people this year? I bet Hermione's definitely going to be the Head girl… and I bet… I bet that… you'd probably be the Head boy…" finished Ron, finishing the last statement somewhat vaguely.

"Yeah, hope so! Though it won't be bad if you were Head boy, Ron," said Harry, happy that they stopped fighting.

Ron grinned cheekily in embarrassment. "Thanks Harry. But no matter who's the Head boy, we're going to make this the year of our lives and hell for the Slytherins, right?"

Harry nodded earnestly. He was excited about the upcoming year… but sad, sad because this year, thought Harry, will be my last.

All these years at Hogwarts, will be like a passing dream.

Might as well make the best of it… was Harry's last sad thought as he entered a chess game with Ron.

--

"Ha! That's right, Draco!" shouted Pansy happily, "We're going to stuff their pants full of water balloons, stick their shirts in mud piles, …-"

"Shut UP Pansy!" roared the very exasperated Draco Malfoy. He had hoped for a good start this year… without Pansy's whining or ranting inappropriate thoughts about Gryffindor pants and shirts.

Nearby, Blaise giggled slightly at her dormmate's stupidity. What a stupid girl, thought Blaise, can't she see that Draco hated her ass?

Blaise was a beautiful young woman, with smooth dark brown hair that dropped to her shoulders, large round brown eyes, had most likely the prettiest face in the school, and a great body. Most Slytherin guys would kill for her, but they all found that it would be useless even if they did. She had never had a relationship.

This was because Blaise though probably the queen of Slytherin was also known as the "Ice Queen," even though she never was cold and was nice to everyone in the Slytherin house. But for some reason, she just didn't find any of her housemates interesting, and the other house-mates were all either scared of her or too taken by her to act civilly towards her. Most likely, she thought, I will find someone from Durmstrang or Beauxbatons…

Which was contrary to Pansy Parkinson, who must have been the whole Slytherin house's play-toy and insists that she is still Draco's girlfriend, when he repeatedly rejected her. Though she had a nice figure too, her pug face made it hard for anyone to look her in the eye and smile at the same time. Plus, she added an extravagant amount of makeup, no doubt her face would be wrinkled when she grew up…

Pansy whined a little bit, then got off Draco's lap (with the latter immediately looking very, very happy) and sat down next to Blaise, grumbling a bit and muttering about non-committed boyfriends.

Draco Malfoy immediately shifted as far as possible away from Pansy, who didn't seem to notice. He hated Pansy, she always tried to hug him or sit on his lap, and even though he always resisted her she kept bouncing back. Talk about resilience. He had his sights on someone else anyway…

"Say, who do you guys think will be the Head boy this year?" asked Crabbe to the compartment. The occupants immediately all sighed exasperatedly, as this question had already been brought up eight times. (once by Draco Malfoy, three by Goyle and four by Crabbe… now five…)

"It's definitely going to be dracie-poo!" sing-songed Pansy, with the subject covering his ears and wincing in mental pain, "and I'm definitely going to be the Head girl, anyone who's got half a brain will make me one…"

Blaise and Theodore Nott, to her right, both sighed exasperatedly again (because this is officially the 9th time that Pansy's said that Draco and her will be the Heads)

This is stupid, thought Blaise, Draco probably has a chance, but no one with a complete brain will make Pansy the Head girl… probably that Granger girl will be it.

Theodore grinned. "If you're Head boy, Draco, you can take off all the points you want off those Gryffindor freaks, hehehehe, and give them so many detentions, oh, this year, you guys, we're definitely going to make the best of it. We're also going to make those Gryffindorks have hell this year! Hehehehe…"

Theodore Nott, was a very good friend of theirs, and plus, his dad was a good friend of the Malfoy's. He had a vampirish look to him, and many people were very scared of him (and sometimes tried to see if garlic worked on him)

The occupants all nodded earnestly and definitively, not knowing that another compartment in the train was thinking the same, but vice versa…

I don't care much for giving those Gryffindors hell, thought Blaise, I just want to give that Harry Potter hell.

Flashback:

"Hello? May I sit here?" asked a tentative 11-year-old Blaise Zabini to the sole occupant of the compartment, a black-haired boy by the name of Harry Potter…

"Uh huh…" he said distantly, wondering why that red-haired boy called Ron was so attracted to his scar, he had left to tell all the others about it…

"So… I'm Blaise Zabini… and you are?" greeted Blaise nervously (she never was really talkative in primary school…)

Harry sighed in relief, thanking god that someone finally didn't know him. But had she seen his oh-so-famous scar yet?

"Harry Potter, duh…" said Harry somewhat obnoxiously, expecting her to say "Oh, how could I not have known! I read all about you…" like that Granger girl who had gone looking for a toad…

Blaise took it the wrong way however. "Oh, so YOU'RE Harry Potter? Quite proud of it, aren't you? For being known for something you didn't actually do-" said Blaise angrily, because that Harry Potter seemed like the stuck-up brat that she had almost expected him to be (her parents had told her so) and she was right.

What the heck, thought Harry, she thinks I'm proud of it? I didn't even know it until a month ago! And she's so rude, accusing me like that…

"Well, if you don't enjoy my company, please leave the compartment…" seethed Harry in gritted teeth. Who the heck is this girl to be asking so nicely and then becoming all so rude all of a sudden… definitely one of those "wrong crowds" that Hagrid had spoken about…

Blaise glared at him. "And for one moment, I thought you'd be better than the average celebrity, but you're not! Fine, I will!" and, feeling very angry indeed, and almost kind of mad at herself for such an outburst, she stomped out of the compartment.

Both felt very mad at themselves for being so impulsive at losing their temper, but justified their actions by thinking that the other was definitely one of those people that they would learn to hate.

End Flashback.

Ever since that day, Harry and Blaise had been on each other's throats nearly every day they saw each other… and their housemates would follow them in going to war with each other… the six years of Hogwarts had been fun, but every year was a catastrophic blur of pranks, curses, spells, hallway battles, Quidditch fouls, and detentions.

--

The train rolls to a stop. All of Hogwarts was very excited about this year… it was just like any other year, but it was known that the Gryffindor-Slytherin rivalry would be at its peak this year, and that the legendary Harry Potter and Draco Malfoy would be squaring off in the final battle… little did they know it was actually Harry Potter and Blaise Zabini, but Draco had been a staunch supporter of Blaise and had more publicly battled Harry than her.

As Harry and his group entered a carriage, they see Neville run up to them. "Hey you guys! Do you mind if I join you?" asked Neville, frantically (as the other carriages are all full)

"Sure!" smiled Ron warmly.

Neville Longbottom, had grown from the pudgy-face he once was. Now, his face looked much older and mature, and was definitely not the squeaking-in-horror-whenever-Snape-sneered-at-him first year anymore. Ever since last year…

The four talked happily as the carriage drew nearer to the entrance of the castle. Harry smiled as he looked at the majestic castle… finally he was back, after an excessive boring summer…

He looked at Hermione, who smiled shyly at him. She usually wasn't like this, but ever since last year, they could never look at each other the same way again.

As they got out of the carriages, Harry noticed a familiar dark-brown hair shine in the twilight. His eyes immediately narrowed and he sighed, it was Blaise Zabini, and he was in for another year in battle zone with the girl…

Begin Flashback:

Potions with the Slytherins. Harry definitely was not looking forward to it… not only was he going to finally meet the infamous Gryffindor-hating Snape that Ron had told him about, he was also going to meet the girl that hated him so much, Blaise Zabini.

Ever since the day on the train, she had glared at him every single day they would see each other in the halls. Harry just glared back, and wondered why the girl was so obsessed in hating him. He hadn't done anything, maybe just been a little arrogant, but that gave her no reason to act like this toward him- she had barely known him!

Harry sat down, and groaned as he saw Blaise Zabini enter the room. Immediately, she glared at him and went to the other side of the room.

After the class filed in, the dungeon room boomed and the infamous Professor Snape strode in.

He finished his introductory speech and began calling out the names… and stopped at Harry's name. Harry gulped.

"Ahh… yes… our new… celebrity…" said Snape softly, closing in on him. "Tell me… what is the difference between wolfsbane and monkhood?!"

Harry gulped. He hadn't even looked at the books!

"I don't know…"

"Tut…tut… seems like fame isn't everything, is it, Potter? That's one point for your cheek, Potter…" said Snape, smiling maliciously as he went back to his desk and started the lesson.

After an hour of lecturing and furious note-taking, Harry sighed as Professor Snape put his book down.

"Well, now, you will be paired up and working on the Shrinking Potion. I hope that you do not mess up…" warned Snape, as he gave each student some supplies.

"Weasley, with Malfoy… Finnegan… with Crabbe, Thomas… with Goyle… Parkinson… with Brown, Patil and Bulstrode… Longbottom and Granger… and… Zabini and Potter…"

Harry nearly cried in despair as he moved next to the furious Slytherin girl. She glared at him.

"Just my luck. Working with an arrogant famous bastard who doesn't know a thing about potions…"

Harry glared. "What's your problem with me?! I never did anything, and you just start attacking me all of a sudden… why do you hate me so much?" he asked, temper rising.

Blaise stared at him incredulously. "Hate you? No, I don't hate you, but you disgust me! You're so famous, and you act like you're all that…"

Harry gaped. "When?! I don't get it, when did I…-"

"See?! That's how arrogant you are, you don't even know if you're being obnoxious or not! I don't feel like failing potions, so you go get the supplies!"

"But… fine… be that way, BE THAT WAY!" yelled Harry as he stomped off to get the lacewing flies from Snape.

They had finished the potion by the end of the period, silently, and glared at each other as they exited the classroom.

End Flashback.

Harry now realized that it was all because of that one "duh" after he told her his name, that brought upon this war. From that day on, things just went downhill.

Oh well, thought Harry as he entered the castle, when I get out of here, at least I won't have to deal with her antics anymore…

The Great Hall looked beautiful as always. Harry gaped at the twilight sky, smiling, as he walked to his table. Nearby, everyone was greeting one another again, exchanging cheerful hellos and heys. Harry grinned at Ron, who did a sort of a whoop and they sat down, anxiously anticipating the upcoming year…

--

Meanwhile, Blaise skipped happily into the Great Hall. The last year, finally, the last year that she would have to stay at this dreadful castle. No matter how much other people liked it, she hated it, because it reminded her every time of one person- Harry Potter.

That arrogant asshole, thought Blaise, can go to hell and back five times for all I care…

Plus, she was excited about her plans of the future. She would be a first class auror, just like her mother, and she would be able to beat that Harry Potter into bloody pulp… even if he was on her side in the battle against Voldemort…

Her family never believed in Voldemort, which was why a lot of the Slytherins disdained her. Her father worked in the Department of Mysteries, while her mother was an Auror of the highest order. But she had quickly shown them that just because she didn't believe in Voldemort didn't mean she didn't know a handy amount of curses and hexes… she had quickly earned their respect as a fierce fighter, and also, a beautiful lady.

"Okay, so, first, you do the cheering charm, and then I'll do the singing charm, right?" asked Pansy in anticipation for their first prank of the year. Ever since Malfoy and Harry had fought that day… everyday after that was a battlefield…

Begin Flashback:

The Slytherins all grinned wickedly when they saw they had Flying Lessons with the Gryffindors. Well, only Draco Malfoy and his two rock buddies did. They were anticipating making fools out of those dumb Gryffies.

"Ha, I'll show that damned Potter who's the better flyer!" said Draco to Blaise after they saw the sign. Blaise grinned. "Ha, I bet he couldn't even fly an inch!" She suggested, though soon she would be proven wrong.

When the day came and went by, Blaise was thoroughly shocked. Not only was Harry Potter a great flyer, he had caught that remembrall without a scratch… and ended up on the Gryffindor Quidditch Team! Jealousy couldn't even describe what Blaise felt… anger at that arrogant Gryffindor hero bastard for getting what she wanted- to be on the team.

The next day, Blaise woke up early and slipped some laughing potion inside Harry's goblet. He ended up laughing and squirting out milk all over his classmates during breakfast, an extremely embarrassing moment for him, and caused uproarious laughter in the Slytherin section.

Somehow, Harry had known that it was her, and the next day her hair was turned to worms and she screamed, running out of the Hall in embarrassment.

Then, every single day, there would be pranks, battles, detentions, and eventually Quidditch fouls between the two groups, one consisting of Harry, Ron, Hermione, Dean, Seamus, Lavendar, and Parvati, and the other consisting of Blaise, Draco, Theodore, Crabbe, Goyle, Pansy, and Millicent. Neville was sort of the bystander… he never fought, the earlier years because scared, but now, well, he was sort of a 'pacifist.'

End Flashback.

Blaise had joined the Slytherin team in her second year with Draco Malfoy as a chaser, and she was quite good too… they won the Quidditch cup last year, but it was probably because she had deliberately fouled Harry last year while he was going for the snitch…

Soon, the first years came in and the sorting began.

--

"And now…" announced Dumbledore as the sorting finished with "Zeladi, Milan!" in Ravenclaw, "Our heads of the students!"

Immediately, everyone did a drum-roll of the tables, as this was a tradition in Hogwarts when they would announce the Head boy and Head girl…

Dumbledore smiled, but if one looked carefully enough they could see a small smirk up his lips… yes… he definitely had something planned…

"From Gryffindor, our Head boy… Harry Potter!" and the whole Gryffindor table cheered like mad.

Harry just blushed furiously and stood up shakily. Wow, thought Harry, who would have expected?

Blaise groaned as loud as she could, but no one heard her. Come on! Thought Blaise, damnit, this year's going to be torture… that biased arrogant obnoxious little hero Gryffindork's going to make this year hell…

Then Dumbledore's smile widened to a full-fledged grin.

"And from Slytherin… our Head girl… BLAISE ZABINI!!!"

The Slytherin table immediately rose up in thundering applause and cheers and whistles.

"YEA BLAISE!!!" congratulated Draco Malfoy, along with Theodore Nott and Millicent Bulstrode. Pansy looked very disappointed and was glaring daggers at Blaise, who stood up, blushing furiously in embarrassment and pride, while Crabbe and Goyle just followed the leader, namely Draco Malfoy.

As Blaise looked across the hall at Harry, he did the same, and their eyes met.

Oh no, they thought, what the hell was that crazy insane old codger thinking?!
