[a/n-1] Yeah I had Hagrid out of Azkaban a bit too soon. Ah well, it was necessary to fit the request. And this time, alix, coarse ya kin correct the grammar but ya gotta tell Hagrid abou it, too. ;]

[a/n0]Have to admit I didn't check Dewey before placing Occlumency. 400s is languages. It more probably belongs in 100s Philosophy, or 200s Religion

[a/n]Had a period of Walking Dead fandom. Mostly fizzled now, didn't last much past Season 6. But that's ok as this rewrites a Season 4 episode. Called 'the darkest of a dark series' The Grove is my favorite of the series. I wonder if the presence of a certain wizard could improve the outcome.

Harry Does Different CDLXVI

Harry Potter and the Walking Dead

Harry Potter was, so far as he knew, the sole survivor of wizarding Britain. His life changed that night at Hogwarts when he woke to bizarre …even by his standards… sounds. It occurred within days of the official ending of the TriWizard Tournament. He was most unpopular. Something like growling filled his ears. He yanked open his 4-poster curtains and was instantly fighting for his life. Creatures vaguely resembling his longtime dormmates Dean and Seamus charged him. Neither responded to any entreaties or demands for explanation. Not even Avada Kedavra, when he resorted to it, affected them. Ultimately, blasting curses took off Dean's legs and Seamus' head. He would not have time to feel horrible about that until doing the same a dozen times. Other students, some French, others Bulgarian he encountered were the same. Never mind Hogwarts friends and enemies alike.

Through one adventure and another, Harry found himself in the Ministry of Magic as it was in the middle of being overrun by vast masses of like creatures. Out of desperation, he threw himself into an alcove where two-and-a-half of them just disappeared from. Unclear of how long he'd been alone on the run; and given he hadn't encountered a live human, less aware of where he was, Harry Potter came upon The Grove.

In the aftermath of the battle of the prison, everyone lost everything. The formerly very secure facility had been completely overrun with Walkers. Refugees scattered in all directions. One small group consisted of a man, a woman, two sisters and a toddler. They found a mid-sized house by itself in a grove. Eager to stop after a week on the run, the house still served by utilities was most welcome.

The family group of unrelated people settled in and did all the things families do. Housekeeping, hunting, exploring their surroundings, the girls even had the beginnings of a vegetable garden. The adults mostly focused on fencing off a safe perimeter. Not much was really needed against the brainless Walkers. Sturdy wires did the job. But it only took a knot of the undead, some bad luck, and a bit of noise to cause an emergency.

"Normal voices?" the young wizard wondered at the sound which just barely reached his ears. He very accurately sprinted off and into action. Harry saw three people, living breathing people, standing their ground against an approaching small army.

Pop. Pop. Pop. And in sequence, the moving bodies in tattered clothes dropped as brains splattered abroad. The fourth of the group was not as fast on her feet as she carried a bundle on her back. Disaster struck as the runner tripped over a gap in the fence, landing face first and spilling her burden, which she immediately tried to rescue.

As Harry ran up, one of the soulless monsters fell near the screaming victim. It caught the bare calf in a gnarled hand and dragged it in to its drooling smelly maw. Reliving an early Wizarding moment, wand flashed pink as he yelled "Diffindo!" And sliced off at the wrist, the hand was shaken off. Together with the others using their guns, the undead were killed or dismembered.

"Mika, come away from him and bring Judith with you." Ordered the thin, almost bald woman.

There was now enough time to note the formerly endangered runner was a blonde girl carrying a baby. Complying, she protested "But Carol! If it wasnt for him I'd be Walker food!"

"Don't argue girl!" came a sharp command from the intimidating a rather mean-looking bearded man, then "And you! Put that thing down! Whatever it is."

Harry shrugged, briefly spinning his wand and vanishing it from sight "As she put it, I saved you from those inferii. Not a great way to start. I was thinking a glass of water, at least, and maybe some information. It's been a long …well I'm not exactly sure how long. By the way, I'm Harry Potter."

"I like him. He's handsome." Declared the older girl with a smile and making a show of sticking out her chest. "Hi! I'm Lizzie."

To this, he smiled "Best compliment I've had in a long time. And in connection, two questions; just how long has it been since things went pear-shaped? And where am i?"

"He does have a point, Tyrese." Carol offered to her partner, then "Well, kid, the first question depends on you a bit. The second is easier. Somewhere between Macon and Atlanta."

This led to a scratch of Harry's head "I know that's not Surrey. Leeds maybe? York? Wales?"

Tyrese was the most worldly having done a military tour, wanted to know "Do you mean England? This is Georgia. Y'know U S of A. Well, what little is left of it. How'd you get here?"

"America!" exclaimed Harry "Well that explains why you all talk weird."

Mika spoke up in protest "Hey! You're the funny one."

"I thought I was the cute one." He winked at the smaller girl, eliciting a giggle.

Tyrese again interjected "Leave them out of this. How could you have got here from England during the apocalypse?"

"You probably won't quite believe me, but simply, magic." He smirked at the disbelieving expressions and continued "I'm quite serious. However long I ran around Britain I got to London and into the Ministry of Magic, which was already overrun with the inferii. One second I was in a Floo fireplace in London, England; next second I was somewhere here in Georgia. That's what you said?"

The Americans gave semi-comprehending nods, the Carol asked "Inferii? That's your term for Walkers? The dead?"

"One of my teachers taught about them a couple years ago." Replied Harry with a nod "Wizards have known about them for centuries, but supposedly they were near impossible to make and real dark magic."

The sisters had worshipful looks. Lizzie wanting to know "Can you fly?" While the more thoughtful Mika asked "Can you just disappear and reappear anywhere."

"Yes to yours, Lizzie, and I have a broom shrunk in my pocket." He answered the older girl first, then the younger "Well that's a little harder, Mika. Yes wizards CAN do it. But I was still two years from that class when things went pear-shaped."

Carol scoffed at the notion "No such thing as magic."

"Course not, miss." Countered Harry "Just what my relatives used to say. Merlin forbid you believe your eyes. Feel free to explain how those arms legs and heads fell off. I don't have a gun. Or this one. Serpensortia!"

In the grass at the adults' feet appeared a rather large snake. Making them reflexively jump.

Just as effortlessly, Harry cast "Vipera evanesca!" causing the snake to burn itself up. He smirked at the flabbergasted looks and remarked "Now if there was still a Ministry, you'd get your memories wiped. And me? I'd goto Azkaban prison, probably without trial."

"Please Tyrese/Carol! Let him stay with us!" the girls pleaded in stereo to their guardians, with Lizzie adding "And he can stay in MYYYY roooomm."

The woman frowned, deeply "I think you are a bit too young for that, Elizabeth Samuels."

"Mrs. Samuels, I think I'm too young for that." Harry offered, refusing to look at either sister.

There was time to correct the mistaken assumption later. But the man who Harry assumed wasn't the girls' father because he was black laughed loudly "Well if saving our collective asse …err… etts ain't enough, promising Lizzie's virtue works for me. I think it's worth a night's sleep. After that, we'll see."

"Thanks …that was Tyrese, right? Harry Potter. So unfair. It took the end of the world and still an ocean, to earn my anonymity." Harry followed him, entirely aware of the sisters whispering. And that he was the topic. But it was somehow more bearable because at least he'd done something to earn it.
