Resident Evil: Devolution

Hogwarts School Year 2005-2006 was to start with relative quietness and some Ministry 'reminders'. Instead, two students are forced to fight and stay alive as they try to survive the experiments made by an alumnus with an agenda. They don't know it yet, but their nightmare has only just begun.

Chapter 4: September 1, 2005 | 2200 Hours | Seventh Floor, Hogwarts Castle

"So…where to first?" Greengrass asked as they reached the Grand Staircase, thankfully still lit with torches. "Potion Stores or Greenhouse?"

"Gryffindor Tower," Harry replied, looking over the railings. When she made to protest, he continued. "I need to resupply…plus, I have a spare survival bag in my trunk you could use."

"Fine…" she relented, giving him a half-hearted glare. "Though I do have to ask, what do you keep in it anyway?"

Harry shrugged. "Well, I have a couple of spray cans, some emergency medical potions, spare ammo, wilderness snacks enough for a week, and a sleeping bag."

Before Greengrass could reply, a loud roar stilled them before the two looked for the source. "Fifth floor!" she shouted, pointing to the hulking figure of G-Argus, wisps of a white fog gathering around him. "Oh shit, he's apparating!"

"Go!" he shouted, pushing Greengrass forward as the broke into a run down the stairs. Seconds later, there was a soft pop behind them followed by a loud roar as they reached the fifth floor. Turning quickly, he pointed his pistol behind him and fired. Argus roared in pain, running forward to ram him, Harry barely dodging him. Greengrass, having reached the stairs, wobbled as it began to flatten downwards from the floor as Argus jumped on to it to attack her.

Harry moved to follow but then the floor suddenly moved away from the fighting, surprising him. 'Floors move?' he asked himself, standing up just as it docked a good distance from the stair-turned-bridge. Thankfully, Greengrass was holding well, casting a powerful slowing spell that made Argus move at snail's pace. Unfortunately, stage two G was becoming more resistant to as two Blasting Curses merely bounced off him to his chagrin. 'There!' Harry thought happily, seeing the stairs the floor docked lead to back to sixth and was near enough for him to jump down the bridge.

"Potter, bloody hurry up!" Greengrass screamed, sounding completely frustrated as Harry ran up the stairs. Running faster, he began thinking of ways to defeat Argus, recalling Claire had to use an improvised shipping container as a battering ram to knock G2 down a hole. He arrived in time to see Argus catch the Exploding Charm with his left and smash it onto the floor, weakening the bridge. Suddenly, he remembered an episode from Naruto he and Dudley watched last year, where Naruto did the same thing with the Rasengan to fight Tsunade, only for her to redirect the incomplete technique downwards and created a crater.

'Ah fuck it!' Harry thought, as he gathered magical energy into his left hand, adopting the form Kakashi used to create the Raikiri as his left arm started shaking painfully. Once formed, he immediately dashed and jumped down over Argus, smashing the condensed magical energy onto his head.

It did the trick - the bridge below broke and Argus fell down screaming, hitting various floors before breaking a hole on the ground floor and into the basement before quieting. Harry would have followed if not for someone crashing into him before landing painful. "What in Merlin and Morgan's name was that Potter?" he heard someone exclaimed as his left arm still throbbed painfully. Blinking, he found himself propped to the wall besides the frozen Fat Lady as Greengrass rummaged his bag, her hair ruffled badly.

"Just water," Harry croaked, getting the Slytherin's attention. "Potions will just make it hurt."

Looking doubtful, she nevertheless gave him water. "What in magic's name did you do, Potter?" she asked as he drank greedily, looking confused. "It looked like some sort of orb."

"Channeled magic into my palm, creating a ball of energy." he replied, grinning cheekily at Greengrass' cute frown. "Won't recommend using but it's useful in certain situations."

Seeing her unamused look, Harry continued. "I did some accidental magic back in Racoon City: flung zombies away from us, enhanced my punches, the likes. It was only when I was checked in New York Magical Hospital did I find out that I was damaging my magical nerves through my reckless use of wandless magic."

"But isn't wandless a great skill?

He nodded. "Yeah but only if you had fine motor skills to handle the magical output without burning the nerves." he explained, chuckling humorlessly. "Since I had none…well, you get the idea."

Greengrass looked exasperated, rolling her eyes. "Of course you'll do something like this Potter." she replied dryly as he tested his left hand, no longer feeling painful. Looking at the portrait besides him, she gave him a look. "Well, we're here - what's the password?"

"Diagonalley," Harry replied as he stood up, the portrait swinging outward. "Well, ready to see the Party Central of Hogwarts?"

She gave him an arched eyebrow. "Potter, the Slytherin dorm has a ballroom." she revealed, looking smug at his surprised face as they entered the dorm. "Don't look surprised, we're – never mind, get what you need."

"Hey, you okay?" he asked, placing his hand on her shoulder. He was surprised at the sudden shift from a proud to subdued demeanor. "What's wrong?"

Greengrass didn't reply as they as they reached the common room. "I remembered Watson's words on how…on how we act superior to those who aren't 'us'." she replied quietly, looking downcast as she flopped down on the couch. "I felt like I was proving him when I lorded over that we have a ballroom and you don't."

Harry didn't say anything as he sat beside her, having agreed with Watson on that issue - Lord knows how many times he was annoyed at Malfoy's egoistic boasting - but that didn't give him the right to do the same over purebloods. "I won't say he's wrong - I mean, look at Malfoy!" he pointed out, making her face twitch with a smile. "But that doesn't mean he's right.

"The point is," he clarified, seeing Greengrass' confused look. "You know where you're wrong and now you have a chance to be better. Change doesn't happen overnight, Greengrass - it takes time like a seed, needing nurturing in order to blossom into something beautiful."

That seemed to do the trick, getting a pretty smile from her. "You have a way with words, Potter." she remarked.

"Come on, let's get my spare kit." he replied, standing. "I think I have a dragonhide jacket as well you can use."

# # # # # # # # # #

"What do we get first?" Harry asked as the two stepped out of the Gryffindor entrance. Thankfully, the staircase was still empty according to Fleur, though she did warn that most of the specimens were still on the other side of Hogwarts. "Fleur said most of them are near the greenhouses."

"Potions first, we're nearer to it anyway." Greengrass replied, fixing her hair into a ponytail. Besides the dragonhide jacket, she raided Hermione's chest for camping clothes that were appropriate for their situation (especially since Hermione was an avid camper). "There's an expanded cabinet in Professor Snape's office containing all the potions the school will ever need."

"Good, I need to replace my pistol as well." he said, cursing that Chris' gift was now lost when he jumped down.

"What makes you think our head of house has a gun?" she asked rhetorically as they began walking down the stairs.

Harry smirked as he fished out the heart-shaped key Snape had given him earlier. "'Cause he told me," he replied, smirking. "Granted he sneered at me but hey, it's the thought that counts!"

She rolled her eyes at him. "I do have to ask," she began, the two reaching the first floor. "I can understand him being hard on everyone but…the way he pushes you is far more than the others - and I'm his apprentice!"

He blinked, surprised. "You're a potion appreciate?"

"Yes," Greengrass answered, looking sad. "I had it in my head that maybe I can cure the curse Astoria has but looks like Watson beat to me first."

"He made the cure to the Maledictus." Harry corrected. "You never know, Watson may need an assistant…although he'll have to answer for his crimes first."

"He'll get the kiss, if any of the pureblood Families get their way - they'll argue he used dark magic to cure it." she replied darkly. "Especially if creating these BOWs are serious enough in the Muggle World."

He winced at that, saying as much to Watson back in the lab. Sighing, he gave her a look. "Those families really don't like it being one upped - especially by a muggleborn."

"There are rumors that some of the inventions of pureblood were actually made by muggleborn or halfbloods." Greengrass replied, snorting. "The Sleekeazy's Hair Potion your grandfather made? Rumor has it's a muggleborn who made it, your grandfather just made it look he made it."

He frowned. "Hm…I haven't seen that particular pop up in our records." Harry answered as they entered the Entrance Hall. "Meh, I'll check it once we're out of here."

"Once we're out of here," she began, leading him to a familiar corridor. "I'm going to load up my tub with so much bubbles and stay in it for the entire day."

He snorted, remembering the plans BSAA cooked up in case of a magical outbreak. "Doubt that, BSAA's going to keep the entire school in confinement until their sure none of us are infected."

"Potter, none of us are bitten." she replied, raising an eyebrow.

He shook his head, explaining how Spencer threatened him by turning everyone in the Great Hall in the infected if he didn't become her test subject. "Oh Morgana, Tori's infected?" Greengrass wailed, fear in her eyes. "Is...is there any cure?"

"There's a vaccine," remembering what Claire told him about WilPharma's clinical trials in India. "But I hear there's some trouble with the production."

"Harry, come in." Fleur's voice filtered through their earpiece. "Watson wants to talk."

"What do mean Spencer infected everyone in the Great Hall?" Watson's voice asked sharply. "Did she threatened you by gassing the place?"

"She said that the T-Mage is already in everyone's bloodstream and she could just activate it in a snap." Harry replied. "It was either fight everyone in the Hall or kill the BOWs."

Watson was quiet for a moment. "Potter," he began slowly. "T-Mage doesn't have a trigger - the moment it enters someone, they turn."

His mind stopped, processing the words Watson said. "Wh-what?"

"Spencer lied to you, Potter. T-Mage acts quickly and doesn't need a trigger."

Before his anger could get the better of him, his mobile rang. Bringing it out, he growled as he pressed the loudspeaker function of the phone. "I see my bluff's been made." Spencer began, sounding amused.

"Fuck you, Spencer!" Harry exclaimed angrily. "Fuck you and your sick games, bitch!"

"Now, now, you wouldn't want me to…'accidentally' open the doors and kill everyone, hm?"

"She's telling the truth," Fleur said over the earpiece. "Two Trynorgs just entered and are heading for the Great Hall with miniguns."

Harry took a deep breath as Spencer laughed at them. "I don't know where you are or who you're with, but I will look for you, I will find you, and I will kill you." he replied calmly, his anger laced in his tone. "So mote it be."

He could hear sharp intakes of breath as his wand heated up, shaking in excitement as magic accepted his declaration. "Good luck." Spencer replied seconds later, her tone mocking but he thought he could hear a slight hitch in her voice. "Oh, and Watson? Watch the clock!"

The call ended as Greengrass laid a comforting hand on his shoulder. "Potter…I-uh, I'm so-"

In a fit of rage, he smashed the mobile on the floor before punching the wall beside him, creating a small hole on it. "Fucking damnit!"

Heaving, he slid down the wall, feeling like shit. "I'm such an idiot." he murmured. "I should have call her on her bluff."

"No you're not."

Harry shot an incredulous look at Greengrass, who met his gaze head on. "You're not an idiot, Potter." she insisted, her eyes narrowed as she knelt before him. "An idiot would be running around like a headless chicken or act like Malfoy, using his father's name as a weapon, even if it was useless."

Harry snorted. 'Not a bad analogy.' "I still fell for her trick…" he countered.

"Did you know Watson made the T-Mage?" she asked, crossing her arms.

"Err…no."

"Did you know ever believed a magical version of this T-Virus could be made?"

Harry shook his head. "There you go!" Greengrass exclaimed, looking happy. "You knew it couldn't happen so when Spencer disproved you, you immediately thought everything else she said as true."

He tried to argue but the Slytherin stopped him. "Even if you did call her bluff, what's to stop her from leaving you be and testing all her BOWs on me?"

That made Harry pause, realizing what she was saying. "Do you see it now, Potter?" Greengrass said, looking at him directly in the eyes. He never realized how the light made her eyes shine bright blue. "You operated with what you knew and you had no reason to believe she was lying to you."

"Thanks Greengrass," he muttered, his mood lifting. She stood up and offered her hand, him grabbing it to get pulled up. "So, the Slytherin Dungeon?"

She merely shot her cute smirk at him. "Toujour Pure," she said, the wall behind him opened. "Welcome, Gryffindor, to the Dungeon of the Slytherins."

Harry noted not much changed since his and Ron's visit back in Second Year. "Huh, it still looks the same." he commented, getting an incredulous look from his Slytherin companion. "Ron and I entered back in Second Year as Crabble and Goyle under polyjuice."

"Poly-let me make a guess, Granger brewed?" Greengrass asked, raising her hands in the air. He nodded, amused at her actions. "Why did you even enter our dorm?"

"The three of us thought Malfoy was the Heir of Slytherin." he replied before hurriedly adding "To be fair, he was rather boastful during that year."

Face-palming, Greengrass gave him a flat look. "You thought Malfoy was the heir." she repeated, unamused. "Draco 'My Father Will Hear This' Malfoy - that Malfoy?"

"I'll admit, my judgement has its good days and bad." Harry replied sheepishly, grimacing. It reminded him of that time he thought Snape wanted to steal the Philosopher's Stone back in first year when it was Quirrell all along. "But Malfoy had a link to the whole Heir business - his father had a hand in causing the whole thing."

"What, Lord Malfoy slipped a dark artifact in someone's unsuspecting hands?" she snorted but looked surprised when he nodded. "Wait really?"

"Yeah…but we got other stuff to fry." Harry replied, looking around. "Where's the office?"

Greengrass took the lead, opening the door to a gloomy and dimly lit room with a fireplace near. The shadowy walls were lined with shelves of large glass jars filled with slimy, revolting things, such as bits of animals and plants, floating in potions of varying colors. Pointing to a cupboard, she said "That's where Professor Snape keeps the emergency potions."

She immediately went to work, no doubt unlocking the wards placed around it. Looking at the desk, he spotted a flower-shape box on it. 'Huh, who would have thought.'

Fishing out the key, he unlocked the box and spotted the revolver immediately, along with boxes of ammo. Cocking the revolver, he immediately loaded the bullets and pocketed the rest (about 60) was about to close the box when he spotted a bulky letter with the Potter seal on it.

"I got the potion, you got the gun?" Greengrass asked as he inspected the letter. "Hey, don't read that!"

He ignored her, inspecting it. "The letter has my family's seal…and it's written by my mother."

Harry looked at the letter with trepidation. He knew Snape and his mother were once friend, if Aunt Pet and Sirius comments were anything to go by. "I know the two were friends but…I know they had a falling out back in their fifth year." he explained, frowning as he spotted the date. "That's odd, it's dated a week after her death."

He pointed at the date when she looked at him in confusion. "You're right…" she muttered.

Making his decision, he unsealed the letter to reveal - to both their surprise - a cassette player. "What's that?" Greengrass asked, frowning at it.

"A cassette player - think a Howler but stores any words spoken to it." he explained, staring at it with apprehension. "I'm playing it."

"Potter, that isn't your."

Harry sighed. "Look, I never got to hear my mother's voice, okay? I…I just want to hear it."

Seeing her anger deflate, he took it as a sign to press play. "If you're listening to this Sev," a female voice began. "It means Riddle killed us, my son's alive, and the ritual worked. That said, I also know you were the reason he targeted us in the first place."

The two stared at each other in confusion. "What, didn't think Dumbledore won't tell us who told him?" Lily continued, as if knowing they'd be confused. "He explained that you overheard the proclamation of the prophecy and in your rush, you didn't stop to think who the targets would be.

"I…I was a horrible person to you Sev, laughing at you when the Marauders was bullying you and ditched you in your time of need." By now, his mother was openly crying and sniffing. "You had every reason to keep on hating me - I married your worst bully, I ended our friendship because of a word spoken in a distressing time - and yet you immediately became a double agent to save me - why Sev, why?

"Guess…guess I'll never know, since I'll be dead by the time you listen to this. I could only hope you forgive me, Sev, for the pain I've caused you - for all the pain we have done to you." Lily pleaded, hiccupping. "To…to sweeten the deal, as Sirius would say, I've hidden my journals in our secret space for your use - although you're going to have wait for my replacement to open it."

She was silent for a moment, as if contemplating over something. "Once…once you got it, could…could you make sure the letters James and I wrote in case we die be given to Harry?" she asked, sounding worried. "Consider this your best friend's final plea to you, Sev. I know you have no obligation to do so but…please?"

There was some ruffle of paper before his mother spoke again. "Well, my time's nearly up. I hope you forgive me, Sev, for all the pain I've caused you...and James and I forgive you for the pain you've created for us." she said sadly. "Live long and prosper."

Harry just stared at the cassette player as the recording ended. "That…that fucking bastard!" he exclaimed angrily, his fist clenching tightly. It was Snape - the very person who hated him with a passion - that made him an orphan.

"Potter…" Greengrass said warily, look at him fearful.

"If you're going to defend him, don't." he growled, glaring at her. "I don't fucking care if he's your Potions Master but THAT BASTARD'S THE REASON BOTH MY PARENTS ARE DEAD!"

"Didn't your mother forgive him?" she countered shakily, both knowing it was unacceptable.

In a fit of rage, he threw everything on desk onto the floor. "WELL I HAVEN'T!" he roared, heaving. "That man has always been breathing down my neck, mocking me for even the tiniest of things, and I just find out that he's the reason fucking Voldemort is still after me!"

"Potter, You-Know-Who is dead!" she countered, wincing at his blatant use of the name. "You-"

He laughed humorlessly. "Well I lied." he replied, kicking Snape's chair. "Tom fucking Riddle is still alive and still wants me dead."

"Who?"

Repeating what Voldemort did back in Second Year, he used his wand to write Tom Marvolo Riddle in the air. "When rearranged, it becomes 'I am Lord Voldemort'." he explained as the letters rearranged themselves. "He - or rather a part of his consciousness - showed me back in Second Year."

Greengrass' eyes narrowed. "What do you mean?"

"He had a diary and somehow placed his consciousness into it." Harry answered. "Lucius Malfoy managed to get his hands on it and then manipulated Ginny to-"

"-use the diary to partially take over her, yes?" she finished, raising an eyebrow. When he nodded, the Slytherin growled, rubbing her forehead. "Bloody hell, he made a Soul Anchor and left it lying about?"

"Soul Anchor?"

Greengrass nodded, looking weary. "Very dark and highly unstable piece of magic. Anyone who creates one becomes immortal at the expense of their humanity." she explained, seeing his confusion. "Thankfully, you already destroyed his anchor so he's fully dead."

Harry snorted, giving her a dry look. "Oh he ain't dead, Greengrass." he replied, surprising her. "Remember last year? The reason it took me a while to get back from the maze was because he kidnapped me to take part in a ritual to give him a new body."

"That's…that's impossible!"

He shot her a look. "I ain't lying, Greengrass."

She shook her head. "No Potter, you don't get it. If he made a Soul Anchor and you destroyed it before the Tournament, he should have already move into the afterlife." she explained, sounding really worried. "The…the fact that he was still alive last year means…"

"Means what, he has another soul anchor?" Harry replied, getting a stiff nod from her. "So what, I mean-"

"Potter, anyone who makes more than one Soul Anchor is literally destroying their soul." Greengrass cut, sounding scared. "The broken soul is literally eaten up by dark magic, turning them into a husk of darkness, driven to commit murder and pain."

He just stared at her, digesting her words. "So…you're saying that my parents were killed by the living embodiment of Dark Magic?" he clarified. When she nodded, he groaned. "Great, not only do I have a professor who killed my parents teaching me, the living embodiment of darkness is also after me."

"Potter, Profe-"

"Don't." Harry warned, glaring at her. "As far I'm concerned, he killed my parents."

Greengrass winced as he made his way out of the office. "Al…alright, I'll just fix this place then meet you outside."

He didn't answer as he left the office, scowling at what he heard. Snape overheard some kind of prophecy about him and when he realized Lily would die, he switched sides just to protect her. 'Fat lot that did…' he thought angrily…though it did raise some questions. What was in that prophecy that made him a target in the first place? And what was this 'secret place' his mom was referring to that it needed her 'replacement' to open it? What was this 'replacement' going to do? 'Damnit, I still need Snape to understand this.' Harry realized, groaning.

Spotting Greengrass leave the office, he waved at her from near the door. "You done?"

She nodded. "Hey, Potter…" she began, looking unsure. "I just want to say that…look, I can't exactly know why Professor Snape did that-"

"Ain't that an understatement."

"-but once this is all over, for the love of magic please don't punch him immediately upon seeing him." she continued, ignoring the interruption.

"Greengrass, do you really think I'll do that?" he asked, feeling incredulous.

She gave him a flat look. "Potter, you're a Gryffindor." she replied, unamused as the door opened. "I expect you to do exactly that. Now come on, it's past eleven - we need that herb now."

Harry merely shook his head, following Greengrass out of the common room. "Right," he said. "Let's find that herb."
