Here it is: the chapter I'm raising this fic's Ao3 rating for. I might also raise the rating here, if I get comments telling me it's too much for K+. Content warnings for disassociation, panic attacks, Harry's childhood, and...school bombings? I'm not sure whether there's a more proper phrase to use. Shadow Harry is definitely tossing real (but non-lethal) explosives at children in this chapter, though. If anyone wants to avoid reading that, skip after Shadow Harry disappears following his chat with Blue and Green and I'll put a summary of what you missed at the bottom.

"No references to Hyrule at all! None!" Blue ranted. "I found more about bloody Atlantis—which was apparently real until one suicidal idiot shattered its water-repelling spells—than I did about Hyrule!"

Harry, more exhausted than angry after the three-hour research session Blue had dragged him into, just shrugged in resignation. "I don't know what you expected," he said. "We never saw anything about Hyrule in the library before all this happened. Why would that have changed?"

"I don't know!" Blue tossed up his hands. "Dumbledore found the Bestiary, so I was just hoping that maybe, since we're the real Hero's stand-ins this time around, we'd be able to find something, too."

"That's a good idea, I guess, but it would've been better if you'd taken Hermione to the library instead of me." Harry stretched, the wound-up muscles in his back and shoulders straining. He wasn't used to hunching over tables and poring over piles of books. "She's about as Ravenclaw as a Gryffindor can get."

Blue looked guilty. "I think I've scared her off," he confessed. "She got more attached to the Bestiary than I thought she would. As determinedly as I've been hounding her to get it back, she's been hiding from me more and more."

"Just apologize to her the next time we're in class—Oh, watch out." Harry saw a Keese flutter out of the wall up ahead. When it dived at them, he snatched it out of the air like a shadowy Snitch and then threw it hard at the ground. "Hermione would be fine with an apology," he continued as he collected the small green gem the bat had dropped. "I mean, she makes Ron and I apologize for the stupid things we say all the time and it doesn't take too long for her to calm down after."

"I suppose," Blue sighed. "I just wish there were more books about Hyrule for me to study so she and I wouldn't have to fight over the same one. It's not like I can borrow a Bestiary from another House; the books vanish and reappear in the common room if you try to take them into the halls."

"We could ask around the portraits if you like," Harry offered. "Professor Dumbledore said a portrait told him where to look. Besides, with Quidditch practices cancelled for however long, it's not like we've got anything better to do."

The determined fire re-lit in Blue's eyes. "Maybe we can track down the portrait that started the message down the grapevine!" he declared. "Let's go!" He jogged down the corridor.

Harry groaned and picked up his pace to follow Blue. As he did, he noticed a dull sinking sensation behind his navel—a warning. He experienced the same vague sense of dread every time a trap was nearby or something in the castle changed. Sometimes it went off just before a Moblin or a Phantom stepped around the corner.

Straining his ears to listen for a Moblin's clicking footsteps, clanking Phantom armor, the warning chime of a Wizzrobe, or the deep rumble of approaching giant marbles, Harry caught up to Blue and then gripped the boy's shoulder. "Slow down for a minute," he said lowly to his counterpart. "Something's wrong here."

"Like what?" Blue peered around. "I don't see anything. Do you think you're picking up on a Keese swarm about to come through the wall?"

"Keese don't set anything off. They're too weak," Harry replied. The sensation of dread suddenly pulsed, making him look around wildly for its source. "Come out, wherever you are!" he shouted to the empty corridor. The strangely empty corridor, now that he thought about it. There were usually at least a few upper-years milling about this close to the library.

With a sound like bubbling mud, a lump of shadow rose from the ground in front of Harry and Blue. They pulled out their swords and hung back, unsure of what monster had decided to challenge them.

The shadow grew taller and thinner, gaining more definition. Then it developed a pale gray face and grinned at them. "Hello, Heroes," Shadow Harry said cheerfully. "Heard you've been having trouble at the library."

"You've been spying on us," Blue accused. "Why? What does Vaati have to gain?"

Shadow Harry shrugged. "Not much, given what I've seen so far. He just wanted to see if you were like all the others who've challenged him. You aren't quite the same—you talk a lot more, for one thing—but you fall under the heading of 'undersized, recklessly brave child', so close enough. The other Heroes definitely had better sword skills at this point, though."

Harry frowned. "How would you know? How old are you, if you know what the other Heroes were like? What are you?"

"I'm as old as you are," said the shadow. "You and the legacy you've somehow managed to stumble across, anyway. Just as the Hero represents the light, I am the darkness. You bring order; I bring chaos." He grinned in a dashingly malevolent way. "I must say, though, after millennia of being 'Dark Link' or 'Shadow Link', it's a nice change of pace to be called 'Shadow Harry'."

"Vaati isn't that old. We've read his story," Blue remarked. "You're more ancient than he is. Why does he control you?"

Shadow Harry's face contorted in anger, a flash of something beastly peeking through. His eyes flared like sickly yellow flames, his bared teeth flickering between Harry's crooked assortment and monstrous fangs. The boy's expression smoothed into a simple frown a moment later. "Being a dark spirit has its drawbacks. Generally if you see me flying around, it's because someone even worse than me is digging their claws into Hyrule. How they'll decide to treat me during their world takeover is a total crapshoot." He shrugged in a "what can you do" sort of way. "With my current boss, all I can do is hope he's in a better mood the next time he breaks out from whatever prison you four manage to stuff him in. Since he isn't in a good mood right now, though, I'm just going to have to get on with this stupid errand he decided to drop in my lap." He dug into his shifting, smoky robes. "It's the worst," he complained. "Not what I was designed to do at all."

"You don't like serving Vaati?" Harry asked. It fit with what little he'd seen of his doppelganger so far; he hadn't struck Harry as malicious, despite setting a giant Keese on them. The shadow had seemed apathetic, perhaps mildly amused by their suffering at worst.

"Normally I do, but he's way less fun than he was last time. He never had such an agenda before, and keeps using me in all the wrong ways just to push his big plan ahead." He sighed and shook his head. "There's something about this place that's making him act all weird, I swear."

Shadow Harry pulled a blue sphere from his robes. "Now, this here is a bomb, crafted by yours truly to cause maximum mayhem." He made a flourishing motion toward it the explosive, which looked like it had been plucked out of a cartoon. "This probably won't kill you, but I've never used them in a building before, so even I'm not sure what it might do. My advice is to run and tell everyone else to run with you." He grinned with dark mischief and cupped one hand by his mouth. "Since the boss isn't listening, I'll let you in on a secret: he ordered me to kill everyone in the castle, but I don't wanna. Sure is a stroke of luck for you that I'm a spirit of chaos, not death, isn't it? I promise not to maim your classmates too badly if you promise not to tell on me." He winked and tossed the object into the air. "One down, nine to go!" he called out, and then he sank into the stone floor.

The ball expanded in jerky bursts as it flew, swelling until it was the size of a small car. Harry and Blue were already running by the time it landed with a ground-shaking thud.

Harry was overcome by a floaty sense of nothingness as he fled. It was the same state he found himself in whenever he had to escape Dudley's gang or endure a beating. His mind would fade into the distance and his body would take over. Only seeing the hallway flying by him, he was barely conscious of his legs powering along. His voice called out every now and then, probably a warning to the other students. Harry passed them by so quickly that he wasn't sure whether he'd told them to run.

A concussive "BANG" dragged his untethered mind back down to Earth. The air gave him a hard shove and his ears popped painfully.

Harry stumbled toward a wall and leaned on it for support. "Th-that was the bomb?" he asked shakily. He became aware that his legs felt like they were made of cement and his lungs were on fire. How far and how fast had he run?

"That was the bomb," his voice confirmed. Harry looked to the side and was mildly surprised to see Blue. He'd completely forgotten about him while he'd been on the retreat. In all his years of evading Dudley, Harry had never had anyone run with him before.

"He said he had ten of those," Blue said, his eyes wide. He stared down the hall in the direction they'd escaped from. "He never said they were all for us."

Harry's heart skipped a beat. He imagined Ron and Hermione walking around a corner and seeing the bomb only as it went off. There would be so much blood and—

Blue gripped his shoulder, hard. "Green, don't," he said sharply. From the pale, sickened look on his face, he'd been imagining the same thing as Harry. "We need to tell a teacher. Professor Flitwick's office is on this floor. Let's go."

"Okay." Harry focused on making his aching legs move and nothing else.

"Draco, while I may be your godfather, that does not mean I'm the one to whom you're obligated to bring every grievance," Professor Snape said with a sigh. "But I digress. What is the matter, boy?"

"Potter's in trouble," Draco declared. "Now that we're allies, that's a bad thing. I want to find a way to fix this."

Professor Snape's expression soured. "You want to help that arrogant little toerag? I thought I'd taught you better than this, Draco."

Draco shook his head. "He isn't arrogant and he's actually…decent. He isn't nearly as nasty as I thought he'd be, given all I've done to discredit him."

"That's just him using his Golden Boy charm on you. Potter has always excelled at getting people to come to his side, even those who were doubtful at first." The venom in his voice unnerved Draco. He was still iffy on Potter, but he doubted the boy had done anything to deserve that much loathing. "Trust me, whatever trouble he says he's in, it's likely a ploy to get you to do something for him."

"That's just it, Professor. He hasn't really said anything. He told me this thing could make him even more famous, and there hasn't been a peep from him," Draco said. "I think it's something he wants to keep secret."

"A dangerous thing he wants to keep secret, you say?" Snape asked with a note of interest. "That sounds potentially useful."

"No, Professor, you don't understand." Malfoy leaned forward, putting both hands on the professor's desk. "I think those Muggles he lives with are hurting him," he said in lowered tones. "The yellow Potter's boggart turned into his uncle, Professor. One of the rumors going about the muggleborn and halfblood population of this castle is that his family's been mistreating him. I went to ask Granger about it and she said Muggles have made a study of this thing, like it's common in their world. What if Potter's family is like that, Professor?"

The Potion's Master's face had gone curiously blank while Draco had been speaking. His mouth scrunched slightly and his dark eyes flashed, as though he were embroiled in a fierce internal debate, and then his features relaxed once more. "I assure you that, whatever you've heard, it's a lie that came from Potter's mouth," he said smoothly. "Now, if you'll excuse me, I have several essays to—"

Everything in the office rattled as a strong tremor went through the room. It was only Professor Snape's quick reflexes and silent spellcasting that saved his many jarred specimens from jittering off of their shelves. The man looked up at the ceiling with an intense frown. "What in Merlin's name is going on up there?"

"Probably the Weasley twins experimenting again," Draco said with a shrug. Malfoys weren't supposed to associate with poor, Muggle-loving blood-traitors like the Weasleys, but he liked some of the twins' ideas. "Maybe coming up with a new kind of Dungbomb."

Professor Snape remained tense. "No…Those two are troublemakers, but they aren't mad enough to test something with a concussive blast like that within the walls of Hogwarts," he said. "Stay here, Draco. I believe the Headmaster needs to be notified." He stood up from his desk and went through the door to his private quarters. He was going to Floo to the Headmaster's office from there, Draco knew.

"Potter, if you had anything to do with this, I swear I'm not bailing you out of trouble with Professor Snape," Draco muttered to the ceiling. "I already have one problem I'm trying to help you with."

Stepping out of the office, Draco was caught up in a storm of worried licks from Dog, whom he'd directed to wait outside. "Ugh, stop it! I'm fine, can't you see?" Draco protested. When his pet obediently let up, he cast a cleaning spell on his face and grumbled, "I don't know why you're convinced my godfather is going to chop me up for potion ingredients. He might seem evil to you, but that's just because he's never been fond of dogs—especially big ones."

Upon hearing this, Dog hung his head.

Draco gave him a fond pat. "It's not your fault you could pass as a bear, you silly mutt. Besides, only a beast your size is worthy of serving a Malfoy like me."

Dog rolled his eyes and dragged his tongue up Draco's cheek with pointed slowness.

"Well, my family is great," Draco defended as he cleaned his face off again. "I deserve to get a swelled head about it." He led the way toward the dormitories. "While we're stuck in here, we might as well find a way to entertain ourselves. How about making Crabbe and Goyle play against one another at chess again? They're both so painfully awful at it that—"

BOOOOMMMM!

The floor shook and Draco stumbled. Dog ducked underneath him before his chin hit the stone. "What is this?" Draco murmured into Dog's shaggy fur, his eyes following the trails of dust falling from the ceiling. The tremors had stopped almost as soon as they'd come, but they had been thrice as strong as the ones that had struck in Professor Snape's office. Unless the Weasley twins had learned to Apparate within the castle's strict wards, they couldn't have set off one of their experiments so far away from and then so close to the dungeons within such a short interval.

Pansy Parkinson stepped over a couple of fallen first-years and hurried to Draco's side. "Are you alright, Draco?" she simpered.

"I'm fine," he told her. "Did I miss something while I was in the professor's office? What's going on?"

"An earthquake, maybe?" she said uncertainly. "We don't know any more than you do."

"I know a bit more than you do, then." Draco stood up with Dog's assistance. His pet leaned firmly against him afterward, a look of wariness in his intelligent gray eyes. "Whatever's causing it, it's an explosive. Also, whoever's causing it, they can either move awfully fast or they've planted these things all over the school."

"But why?" Pansy asked. She cast her gaze over the common room, which was still in disarray and now full of crying first-years, then turned back to Malfoy. "Everyone's shaken, but fine…" She trailed off, a nasty, gleeful look forming on her features. "Unless these bombs are only for those who shouldn't be at Hogwarts."

Malfoy was confused for a moment. '"Shouldn't"? Who's at Hogwarts that shouldn't—Oh, right. Potter's been having too much influence on me.' "Yes, it could be that the bombs are for the Mudbloods and other riff-raff," he agreed. "That all depends on who's dropping them, though."

"I think you'll find you know him rather well, Malfoy," a familiar voice said in a very unfamiliar way.

"Potter?!" Draco said incredulously. In the center of the common room, from absolutely nowhere, had appeared the yellow-eyed Potter.

But no…This wasn't Yellow. His eyes were more grayish than golden, his hair was an uninterrupted shock of inky black, and his skin was the color of dirty slush. This creature had Potter's face, but it wasn't any of the boy's multicolored aspects.

"You're the shadow," he cried. "That spy the Potters were talking about!" He plunged his hand into his pocket, closing it around his wand. "Get away from that thing!" he shouted to his fellow Slytherins, who were all gawking at the doppelganger like idiots. "That's not Potter!"

"No, not quite," the shadow purred in agreement. His glowing irises brightened as he smiled at Draco. "I'm the shadow of every Hero. I've got to say, I like the new kid. Seems like he has some personal demons I can work with." He reached into his robes and pulled out a bright blue ceramic sphere. "You'd better run, little mages!" he called as he lofted it into the air. "Wouldn't want to cause a bloody mess, now, would you?"

Draco's eyes followed the ball as it swelled to the size of a Quaffle, then a person, then a hippogriff. It sprouted a thick white cord that sparked and fizzed on one end, and a large, white "10" appeared on its surface. When it landed, the number switched to "9".

"Wh-What is that?" Pansy demanded as the count became "8". She backed away as she spoke. "A firework?"

"A bomb!" Draco shrilled. He ran for the nearest door that caught his eye, which happened to be the exit to the Slytherin dormitory. "RUN!" he screamed over his shoulder. He didn't care that his voice had cracked, or that it had sounded as shrill as a girl's. He just wanted to live, and not come back to a common room painted red.

Ron caught Red by the elbow as he stumbled into him. Around them, the torches flickered and their metal brackets squeaked.

"Did that sound like an explosion to you?" Red asked with a raised eyebrow.

"Like a far-off one, yeah," Ron confirmed. "I don't think it was on this level."

"The ground shook a lot, so maybe one floor down?" Yellow suggested. He bit his lip. "Although I'm not sure if it's a good idea to check it out. That sounded big, and there might be more of whatever that was." Unlike his brothers, Yellow didn't always want to run straight into danger. Sometimes it was more prudent to stop and think, or wait until the danger was a little less…dangerous.

Red rolled his eyes. "Come on, Yellow. We've followed trails of spiders, crashed a car into the Whomping Willow, fought our possessed teacher, and shoved our wand up a troll's nose. A piddly little explosion is nothing." He grabbed Yellow by the wrist and towed him along as he and Ron sought out a staircase.

They were accosted by a bow-wielding Moblin just before the stairwell. Ron's ear got clipped by an arrow during one mistimed dodge and he landed in an impromptu roll that looked like it caused a few bruises. He hopped back to his feet with a cry of "Expelliarmus!"

The Moblin's bow tried to jump from its hands, but the monster stubbornly held on. Then it nocked another arrow. "Really?" Ron cried in exasperation.

"It kind of worked, though!" Yellow encouraged. He pulled out his own wand with the hand not holding his sword and cast a Disarming Charm as he and Red dashed toward the monster. The Moblin dropped its arrow as it struggled to keep hold of his weapon.

Red and Yellow converged on the monster with their swords before it could raise its bow. They attacked one side each, hacking with abandon. The way to fight Moblins was to get as many hits in before it could land an attack of its own. Technique didn't matter, just speed.

The Moblin suddenly punched out, catching Red in the torso and knocking him off his feet. Yellow grunted at the dull burst of pain in his solar plexus, but was glad not to feel the sharp stab of a broken rib. Red would be fine, just bruised. Yellow came up behind the Moblin and slashed his sword across its shoulders. The monster turned around, swinging its bow like a club. Yellow ducked the heavy attack, shivering at the whoosh of wind overhead, dashed around it, and sliced at its hamstrings with a two-handed grip. When the Moblin stumbled, he drove his sword into its spine, hoping that finished it off.

To his relief, instead of turning around and punching his head off, the monster collapsed and then vanished in the customary puff of smoke. It left behind a golden gem that Yellow was happy to collect. "Are you alright?" he asked, helping Red up.

"Fine," Red wheezed. "Lungs just hurt."

"And you, Ron…?" Yellow paled at the blood running down the side of Ron's neck. "Oh my goodness, are you okay?"

Ron put his hand to his bleeding ear. "Er, I think—"

The floor rumbled again, this time hard enough to make everyone lose their footing. Yellow landed painfully on his hands and knees, causing Red to yelp from the feedback he received over their connection. "Sorry," Yellow said sheepishly. He sat down and tucked his stinging knees to his chest. "I really think we should just find somewhere safe to wait this out. Maybe the Hospital Wing, so Ron can get his ear fixed," he said to his friends. "That explosion was really big. Investigating after whatever's happening is probably better." After all, if whatever it was had the strength to shake the whole floor, there wasn't anything Yellow and his friends could do about it. Except get too close and die, but he didn't want to think about that.

"You know, maybe Yellow's right," Ron said. He grimaced at his bloodied fingers. "Not much we can do against an explosion."

"Oh, fine. We can go do the safe, boring thing. I need less sensible friends," Red griped, though he helped Ron and Yellow to their feet. "The Hospital Wing, then?" he asked.

"Yeah, unless you've learned any healing spells since you split off of Harry," Ron replied.

Red laughed. "Me, go out of my way to study something? No, not likely." He set off at a fast pace toward the stairs. "Off we go to Madam Pomfrey!"

They entered the stairwell, only to find complete pandemonium. Students poured up and down the stairs in a roiling stampede. No one seemed to have any place in mind to go, other than "away"; most had expressions of blind panic or pure terror. On staircases that had meandered away from their moorings, students huddled together in protective clumps. The cries of panicked children echoed within the cavernous vertical space.

Seeing so many of his classmates acting like scattered ants, Yellow himself felt the urge to flee. He hid halfway behind Ron, who gave him a funny look over his shoulder but didn't pull away.

Red, ever confident, stepped forward and cupped his hands over his mouth. "OI!" he bellowed over the din. "WHAT'RE YOU RUNNING FROM?"

A number of heads turned toward him, causing several pileups on the stairs. Yellow winced in sympathy for the trampled unfortunates.

"What d'you mean, what are we running from?!" an upper-year Ravenclaw asked incredulously. "The bombs, of course! Why aren't you running?"

"Bombs?" Red repeated. "What are you talking about?"

"Yellow Potter's gone mental!" someone else shouted. The twig-limbed Hufflepuff wiggled out from a knot of tangled students. "He's tossing these huge bombs all over the place!"

"What?!" Yellow gasped. He stepped out from behind Ron. "I would never do that!" he cried. How could they believe him capable of such a thing? He had never done anything to hurt anyone, and he never would! "It has to be someone else!"

"It's him!" the Ravenclaw shrieked. "He's going to blow up the staircases!"

"Wait, you idiots—!" Red began, but all sense of reason had left his classmates' heads. A river of black robes flowed through every exit but the one Yellow stood in front of, vanishing into the hallways beyond within seconds.

Red, Yellow, and Ron stood in befuddled silence until the castle was wracked by another shockwave. The staircases around them shivered perceptibly. Some stopped mid-shift, as though stunned by the tremors.

Tears sprang to Yellow's eyes. "That was another bomb," he whimpered. "A lot of people might have gotten hurt, or k-killed, and they all think it's my fault!" He hugged himself tightly, remembering the many, many times when he'd been blamed for things others had done. Dudley had broken a vase, but no, Harry had done it. The teachers had instituted a healthier lunch policy, and oh, Harry must have said something to make them change it. Harry had gotten a detention and a call home for starting a fight, even though Dudley had been sitting on him and pummeling his face. So, of course, Harry was now the one throwing bombs and blowing people up! Of course he was!

"Yellow." Scarlet eyes appeared in front of him, a pair of brown ones hovering nearby. "Take deep breaths and slow down. You're gonna pass out, otherwise."

Realizing that he was indeed panting for air, Yellow forced himself to breathe at a more measured pace. "I can't handle this, Red," he said, winding his fingers into the sleeve of his counterpart's robe. "I'm not the part of Harry that deals with things like this!"

He wasn't smart or brave or cunning like his other selves. Yellow was the passive, mild-mannered Harry who only acted when he absolutely had to. He was the one that kept them safe when his relatives were at their most malicious and no amount of courage, cleverness, or ambition would help the situation. He kept his head down and did ten chores in one afternoon if Aunt Petunia started eyeing her frying pan too eagerly; when Uncle Vernon was puffing up and turning purple, he offered apologies and then stayed in his room like an uncomplaining little angel; if Dudley was in the mood to blame Harry for something or go Harry-Hunting, Yellow was the one who offered to do his cousin's homework or fail a test to make Dudley's grades look better by comparison. He was a mediator who worked his magic through shows of quiet submission and feats of backbreaking work; such tactics would be useless against a mob of angry classmates.

"There are four of us now, remember? We'll help you," Red soothed. "Ron and Hermione, too. We're gonna get through this, just like we did with the 'Heir of Slytherin' BS last year."

"I wasn't getting accused of being a ruddy terrorist last year, was I?!"

"No, but you were accused of setting a thousand-year-old monster on muggleborns to Petrify them," Ron replied. "We'll protect you if anyone starts looking shifty. I'll talk to Fred and George, too. They'd definitely help, and they know loads of spells."

Yellow took deeper, slower breaths as the panic eased. He had help, now. He'd never had that before. Dudley had always made sure no one his age would want to be his friend and Aunt Petunia had turned every adult in the neighborhood against him with her claims of Harry's "mental instability". He had friends and allies now, though, just as he had last year and the year before that. Yellow clung to the idea like a lifeline; he wasn't unprotected and alone anymore.

"I know I'm bleeding, but I think I'd rather wait here until the bombs stop than get trampled trying to find Madam Pomfrey. I've gotten run over enough times by my brothers to know how much it hurts," Ron declared, sitting down beside the archway leading to the stairwell. "After all this, we can get Hermione to explain what's going on. She knows everything."

"I'm hoping she at least knows I didn't do this," Yellow mumbled as he slid down the wall. He sat in a scared huddle. "Why would anyone want to blow up Hogwarts? It's a school full of kids—pureblood kids, too. Voldemort wouldn't want to risk hurting them, would he?"

"I don't think You-Know-Who could even get into the school, now that the wards are screwed up," Ron said. "This has to be something to do with what's happened this year, with all the weird old magic floating around. What about that bloke you said was spying on us in Defense? He looks like you lot, doesn't he, even though he's something else?"

Yellow and Red exchanged looks of horrified realization. "Someone with yellow eyes and Harry Potter's face is chucking giant bombs at people," Red groaned, pointing to his twin. "Wrong shade of yellow, and no stripe in the hair, but I don't think people pay that much attention when they think they're gonna die. They've mixed up Shadow Harry with Yellow!"

"It doesn't help that we've only told Professor Dumbledore, Malfoy, and Ron about Shadow Harry." Yellow sighed, thumping his head against the wall. "Gosh darn it."

"Then either we'll tell everyone, or the nerds will come up with a political, smart way to make everyone not hate you," Red decided. "Now we've got a plan, so that's good."

The castle thrummed, a distant blast sending its power through the stone structure.

Yellow squeezed his eyes shut, fighting not to imagine how many people had just been injured…or worse. "At least one thing is," he murmured.

To summarize: Green and Blue go to Professor Flitwick to report what's happening; Draco tells Snape he's worried Harry is being abused by his Muggle family, which Snape brushes off because of course; Shadow Harry attacks various random areas of Hyrule Castle, including the Slytherin common room; because Shadow Harry has yellow eyes and few people know of his existence, many Hogwarts students mistake him for Yellow. I'm probably going to regret making Yellow an accidental scapegoat, since that will involve me having to write in more minor characters and make them act mean to him. Adding characters and writing conflict is...not my wheelhouse, but this kind of reaction just seemed in-character for the student body of Hogwarts, given how quick Harry's classmates were to suspect him in the second book when he turned out to be a Parseltongue.

It may sound cruel, but the mental image of Shadow Harry throwing his signature skull bombs inside of Hogwarts was one of the first things I thought of when I started conceptualizing this crossover four years ago. I was playing Four Swords Adventures and getting annoyed at Shadow Link, and then I imagined how horrific his favorite player-hassling activity would be if it were placed in the wildly different context of Hogwarts Castle.
