Hermione Granger sat down on the couch looking at the two Daily Prophet articles in front of her. They were the last two wizarding newspapers she had ever purchased. After that she had gone to the Muggle world, lived like a Muggle, spoke like a Muggle. She grinned wryly remembering how long it had taken for her to stop saying "Great wizards!" and "By Merlin's beard!"

She sighed again and picked up the first article. She grinned slightly at the byline, "By Colin Creevey", but went back into sadness as she read the headline.

"DUMBLEDORE BETRAYED BY FORMER STUDENT"

She shook her head again. It was hard to imagine, Ron Weasley, Death Eater? Everyone had figured Ron would be perfect for Dumbledore's Secret-Keeper. He was a high-ranking leader in the Light Army, and when Dumbledore had been forced to go into hiding...well...he had been right there. Harry had begged for the job, but as commander of the Lights he had too much on his plate already.

The other one was even more depressing.

"POTTER MISSING, PRESUMED DEAD."

Hermione still found it hard to believe. At first everyone thought he was on another covert mission for the Army, but he never came back. There were extensive searches for him, McGonagall had arranged them, she was so worried...

Hermione sat the clippings on the table in front of her. It was impossible to believe that Harry and Ron, her best friends from school were both gone. Tears welling up in her eyes, she took the clippings and ripped them up. She felt like she had when she broke her wand, like she was turning back with no return. And these clippings, they were last magical things she owned...

After ripping them into shreds, Hermione dumped them in the nearest trash bin, and went up stairs and slept fitfully.

So imagine the shock of Hermione Granger the next day, when a large snowy owl smashed through her window, spraying glass everywhere.

First Hermione felt like she was having a heart attack, then her face contorted into total shock, then fear, then curiosity. She reached over and picked the owl up, pulling a small shard of glass out it's feathers. After she did this, she automatically checked the owls leg for a letter. Not surprisingly, a piece of parchment was wrapped around the owls leg. She took it off, set the owl on her nightstand, and unrolled the parchment.

Hermione,

Hermione stared back at the owl. Lily. That was Harry's mum's name! But..she chided herself for getting her hopes up. Harry and Ron were as good as dead, if they weren't already. She now wished she had her wand. Wait, had she, Hermione Granger, just wish for her wand? Well, no duh, the intellectual side of her answered. There's a spell for knowing who sent an unsigned letter.

Hermione sighed, she still knew all of her spells, she never could forget them. How could she not after spending so much time studying them? This one was particularly easy, Revily. Nothing to it. Hermione had gotten quite good with doing simple spells without her wand, but...that had been years ago.

Oh, why not try it just for fun? The other half, daring and funny, which was so rarely shown, asked of her other side. Hermione shrugged, and concentrated purely on wishing to know who sent the letter.

"Revily!" she shouted, to her surprise a purple light shot out of her fingers and it the scroll. It smoked for a second, and then new writing could be visibly seen at the bottom.

Harry James Potter.

Hermione's eyes widened with complete shock. This day could not get any weirder, she thought. Naturally, she was wrong. She heard a sound like a plane flying very low, and quickly turned her head. There, outside of her window, was an unpainted, DeLorean apparently having engine trouble, and hovering over her back yard.

Hermione shook her head, she did not just see that, she did not just do magic, Harry is not alive. Hermione shut her eyes tightly and opened then again. The DeLorean was still there, only this time smoke was coming out it's hood and it was free-falling towards her lawn. This is insanity! she thought as she ran downstairs, still clad in her white nightgown.

*Inside the DeLorean*

"Marty!" Emment Brown said angrily, running a hand through his wild stark-white hair, "How many times have I told you, never to try and use time-travel for your own success!"

Eighteen year old Marty McFly winced in pain. His knee had crashed into the dash when the time machine had smashed on the grass.

"Honestly! Marty, what in Heaven's name made you wish to go to Roman times?"

Marty grinned sheepishly, "To make some old Roman gold off a gladiator fight so I could return to future with millions by selling the old coins."

The Doc rolled his eyes and sighed, "Yes Marty, but I might add that the gladiator who bet on was supposed to die, and because he didn't, in the future the Roman Empire conquered the world! How many times I've I told you to never cause a paradox?"

Marty was about to defend himself when a pretty chesnut-haired woman leaned her head in the broken window, careful not to cut herself on the pointed pieces of glass.

"May I help you?"

"Yes, thank you Miss-"

"Granger, Hermione Granger," she finished.

Marty nodded and tried to unlock the door, it wouldn't work. He sighed, "Anyway you can open the door?"

Hermione nodded and grunted as she pulled on the door handle, finally after giving up, she swore, pointed her hand at the door and bellowed out "Aolohmora!" and the door opened as if by magic.

Marty was thunderstruck, as he got out, careful not to hid his head on the wing-like door of the DeLorean. The Doc got out of the other side of the car, and walked over bubbling with excitement.

"Great Scott! I always figured, I was expected but I never thought I'd see one! You are-"

"A witch," Hermione answered as she straightened out her nightgown, and nodded, "And you are?"

Marty shook his head slowly, witches! This was incredible, as well as amazingly insane, "Uh, I'm Marty McFly."

"And I'm Emment Brown," the Doc said, rushing over to shake Hermione's hand. Hermione grinned in spite of herself, this was quite an interesting Muggle...

"So, um," Hermione bit her lip, "Can I show you inside. I need to go upstairs and change. Then I'll make you breakfast, and you can tell me how in the world if your Muggles, how you got hold of a flying car."

Emment Brown and Marty McFly grinned and nodded.

Upstairs, Hermione pulled out a pen and notebook paper. She had long ago thrown out her quills and parchment scrolls. What should she write, and she couldn't let those Muggles below wait too long...she sighed and just began writing:

Dear Harry,

Perhaps not the most tactful way to write a letter, but still...

I thought you were dead! For cripes sake Harry, come back! The world needs you! I need you! I'll bet even Ron would need you if he hadn't turned Dark. Speaking of Ron, how could you leave the Weasleys? The Death Eaters beat the Light Army Harry. I escaped and have lived as a Muggle, but its only a matter of time before they gain all the power he'll need! Harry, come back!

With that, Hermione rolled the paper up, attached it to Lily's leg with a rubber band and sent her off then joined her "guests" downstairs...

"So, how in the name of Heaven did you get a flying car?" Hermione asked as she dished out Pop Tarts and orange juice. She never had been much of a cook.

Marty was busy wolfing down his Pop Tart so Doc Brown began, "Well really, Miss Granger that car is actually a time machine."

Hermione spewed out her orange juice, "You mean Muggles know about time travel, but that can only be done with Time-Turner, and that's magic."

"Not exactly, Miss Granger," the Doc said politely and went into great detail on how his time machine worked as well as why it flew. Hermione grinned when he told her about the Mr. Fusion which ran on garbage and came from the year 2015.

"By the way," Marty said, pausing in mid-bite of a frosted blueberry tart, "Where are we and what year is it?"

Hermione wrinkled her brow for a second, those weren't questions one heard everyday, but she answered simply, telling them the year and that they were in a small hamlet called Filat outside of London.

The two newcomers nodded, and resumed eating. After Hermione finished her food, the Doc announced that he would work on fixing the DeLorean.

"There should be some tools in the garage out back," Hermione informed him. Brown nodded and walked out telling his young partner to come and help him.

Harry Potter groaned, and rolled over. Sharp rocks poked him in the side. He was all but powerless now. Harry James Potter, leader of the Light Army living in an Albanian cave with his old owl Hedwig, and until he sent her, Hedwig's daughter Lily. He hoped Hermione would accept the gift of the owl without wondering too much. Maybe she would assume it was from an admirer.

He looked at the quill and parchment he had stolen from local stores to write to Hermione. Hedwig bit into some of the mice she had captured, Harry wished he could supply for her, but he couldn't risk much.

Writing to Hermione had been quite a risk as well, he was a complete idiot. But...he missed her. He was going to ask her to marry him before he had left to fight Voldemort. As it turned out, Ron already had killed Voldemort and was the new leader of the Dark Side. Neither friend could kill the other, but Ron had done a Power Grabber Curse on Harry and made him little more then a Muggle. He sighed.

Just then, a snowy owl flew awkwardly into Harry's cave. Lily certainly had many of Pigwidgean's genes in her, Harry thought wryly. He picked up Hermione's letter and his eyes went wide open. He quickly scribbled out a response to her letter and sent Lily off.

Hermione Granger looked out the window at the two strangers working on their time machine. It was so strange to think Muggles had invented time travel and she wondered idly if the man was just an old coot. No, she told herself, that car flew, and Hermione knew of no Muggle car that could fly. She was vaguely surprised awhile later when Lily came zooming through the window. Eagerly she tore the letter off Lily's leg who squawked at the injustice. Hermione shrugged and read:

Hermione,

"Well then," Hermione said quietly as she folded over the letter, "Then I'm coming for you."
