I own nothing. All the characters and stuff goes to JK Rowling, yadda yadda.

Tonks widened her eyes as the green light from Bellatrix Lestrange's wand flew towards her. A sudden calm fell over her as she looked at Remus, who reached out for her, with desperate eyes that pleaded her not to go, not to die, not to leave him. She smiled faintly and closed her eyes, waiting, waiting for the curse to hit.

One.

Two.

She counted to ten, and yet felt nothing.

Opening her eyes, a swish of green-lined robes danced as the wearer casted a slew of bone-breakers and fire whip spells towards Voldemort's right hand. A name sprang to mind: Tracey Davis, the only halfblood in Slytherin house.

Next to her was a mess of blonde hair. Daphne Greengrass, known as the Ice Queen, and the inseparable - only - friend of Tracey Davis. She smirked as a particularly well aimed Glacius charm caused her opponent Antonin Dolohov to shriek in pain. A swift non-verbal Petrificus Totalus came after.

Davis laughed as she made Bellatrix dance around the curses, a laugh sounded too much like one her opponent would give - and for that matter, Sirius would give - for Tonks' tastes; an intoxicating mixture of insanity and humor. "Is she insane?" She asked Daphne who was now checking if she had any wounds.

"She has a crazy bloodlust sometimes. Best not to get in the way of it."

"Expelliarmus!" Bellatrix's spell hit Davis' arm, and she smiled viciously - before seeing the wand simply twitch in Davis' grasp.

"It tickles," Davis drawled. "Let me show you how to do it properly. Expelliarmus!"

A burst of red light flew from the witch's wand, and slammed full force into the Death Eater, who was knocked back by the overpowered disarming charm. She shrieked madly, and Tonks assumed it was simply at the taunt, before seeing two lumps of flesh hit the ground.

With a jolt, Tonks realised - they were arms. Bellatrix's arms. Davis had quite literally dis-armed Bellatrix.

Bellatrix paled and collapsed, and the two Slytherins disappeared into the fray of battle, with Davis' occasional laughter now recognised by Tonks.

The next time they saw each other, was as Harry Potter was seen dead in Hagrid's arms, and Voldemort commanded the resistance to give up hope.

For a moment, nothing happened. Malfoy twitched and stepped towards the Dark Lord, but then redrew.

Then Davis had howled with laughter.

Everyone stared at her, for a moment, then two. Then Ron Weasley opened his mouth, "SHUT IT YOU SLIMY SNAKE!"

Davis ignored his outburst and turned to Daphne, whose eyes twinkled knowingly.

"I won the bet."

Daphne scowled. "How was I to know the wizarding world was so stupid? Unfair... Shouldn't have bet against... " the Slytherin muttered.

"Fools. Honestly, the Dark Codger couldn't even tell the difference between a male and a female baby?"

"I know, you'd think he'd realise something," Greengrass whined.

"Still, you lost the bet," Davis chuckled.

Davis stepped forward, and her body changed. Suddenly, she looked almost like a replica of a woman whom Tonks had only seen in pictures, with brown eyes.

"Hello Tom." She remarked to the most feared Dark wizard of all time.

"You DARE," he screamed. "ADVADA KEDAVRA!"

The green light rushed towards her, but stopped halfway, and flickered once, twice, and out of existance.

Remus, who had been beside Tonks, gasped as the girl turned such that he could see her better. "Lily..."

"OI BIGOTS OF THE WIZARDING WORLD! I AM ANNOUNCING MY RETURN AS THE SAVIOUR OF THE WIZARDING WORLD!"

"ADVADA KEDAVRA!" Another get of green light flew towards her from the tip of Voldemort's wand, with the same result.

"Now, now, Tom. That's not very nice of you!" She smiled cheerfully. "Bow before me and plead your forgiveness."

"You DARE -" The wizard stopped mid-sentence, and the population of Hogwarts and her defenders watched and gasped in shock as he bent forward, got to his knees and kowtowed to her.

None were more stunned than the teachers, who knew what it truly meant. This meant that this girl, had incredibly much stronger willpower - and thus magical power - than the Dark Lord.

"Much better! Now where was I... Oh right! LADIES AND GENTLEMEN, I AM PLEASED TO ANNOUNCE MYSELF, THE ONE, THE ONLY, HARRIET JANE POTTER! THE GIRL WHO LIVED!"

Voldemort, who had gotten to his feet, snarled. "WHAT TRICKERY IS THIS?"

"Oh Tommy-boy, didn't you listen? I'm the one you tried to kill, all those years ago at Godric's Hollow, don't you remember 'lil ol me?"

"DON'T PLAY WITH ME, GIRL! I KNOW WHO I-"

"AHAHAHAHA! I GET IT! YOU-KNOW-WHO!" She burst into laughter. "But seriously, why don't you believe me? Look, my stand-in's body should be dissolving any time...now," she finished, as Harry Potter's body dissolved into - not ashes - but specks of light, which flew towards the newly christened Harriet. "What a useful spell, honestly. Separates part of my self, so it does make me weaker, but still."

The Death Eaters, who had evidently growing expressions of hatred, finally snapped. One by one, they fired dark curses and jinxes that should have left the girl a vegetable, if they had hit her.

If they had hit her.

The spells slowed to a halt, but did not drop to the ground. Instead, they flew upwards, then streaked towards their casters.

Some squeaked. Some paled. A couple evidently dirtied their robes.

Harriet's smile was that of a cat, who had a mouse and was playing around with it. That predatory smile, made even the seasoned Auror Moody take a step back.

The Death Eaters waited. And waited.

Until a particularly brave - or foolhardy - Death Eater tried to raise his wand at her. Key word: tried. His earlier curse - a Cruciatus - hit him, and he became a snivelling pathetic excuse of a wizard.

Suddenly, the curse stopped. He looked around, then started shrieking again. Somehow, she could control the curse without a single spell.

This went on. And on. And finally, little more than a vegetable, the Death Eater fired a Killing Curse. Not at Harriet, but at himself.

And so the next Death Eater received the same punishment. And the next. And those lucky to have used the Killing Curse were grateful for merciful painless deaths, because the girl in front of them was much more scary than anything they had ever seen.

And soon it was the Dark Codger's turn himself. "Any last words?"

He didn't even have the chance to open his mouth. Tonks almost felt kinda sorry for the poor bastard.

Almost.

The crowds burst into cheers, as they celebrated the end of the Second Wizarding War. But there was still one more thing to be done.

"Daphne, you lost the bet."

"Do I really have to do it now? Here? In front of everyone?" Daphne pleaded.

"Yes. Do it," the now redhead commanded.

"Fine." The blonde got to one knee, and summoned a ring box. Opening it, she asked, "Harriet Jane Potter, O saviour of the World, O light of my life, O -"

"Get to the point, Daph," Harriet glared at her.

"Will you marry me?" Daphne completed.

"YES! YES! A THOUSAND TIMES YES!" She flung her arms around Daphne, and as the crowd wolf-whistled, she gave the most shit-eating grin she ever made.
