Chapter 1: Arrival
Deep in the Hogwarts infirmary, there was a bed that was currently hosting none other than Harry Potter, the boy-who-lived, and now the two-time saviour of Hogwarts School of Witchcraft and wizardry. The black-haired, green-eyed wizard had been told by the school's nurse, Madam Pomfrey, that there was no way on Earth that he was allowed to leave this bed tonight. He didn't like that fact, but honestly, he couldn't really blame her. If he had been in charge and found out that a nurse let someone who had been through what he had just been through walk away without receiving medical help then he'd definitely have to consider firing her.
As Harry lay back, he decided to busy himself by practising some magic, as there really wasn't much else to do given that the only book he had available to him was a transfiguration book that Madam Pomfrey had given him. He put his circle-shaped glass back on and took the book and skimmed through it, finding various spells with different levels of usefulness and interest to him. For example, he didn't really ever think that there would be many cases where he would want to change a cat into a cauldron, 'poor cat' he thought to himself. Nor did he want to turn an owl into opera glasses or turn a teapot into a turtle.
Thankfully there were spells that he could see the point in, the hardening spell, for example, the next time Malfoy decided to be a pest Harry would make his food as hard as stone and let the arrogant bully break his teeth, hopefully, he would talk less.
Eventually, Harry came across a spell that seemed really interesting, the 'draconifors' spell, a spell that was designed to change objects into dragons! Well, not massive fire breathing ones, instead they were all just small transfigured ones. Still, better than nothing. Harry saw that the spell was actually a third-year spell, something that made him hesitate, only for a moment though. He was nearly at the end of his second year, he'd be a third-year soon and didn't think that there was anything wrong with getting some early practise in.
'Plus, who honestly expects a nearly thirteen-year-old Gryffindor to resist the urge to make himself dragons?' He thought to himself.
Harry took a quill that had been lying around on the desk next to him, he mentally repeated the incantation for the spell and practised the wand movements several times. Eventually, Harry was ready, he imagined the dragon he wanted. He had decided that the dragon he would try to make would be a Norwegian Ridgeback like Hagrid's dragon, Norbert, from his first year.
"Draconifors." Harry incanted, aiming his wand at the feather. Nothing happened, much to Harry's disappointment, he took a deep breath and tried again. The quill feather sprouted brown wings from the side and legs grew near the tip, but that was it. It was an odd sight, looking at a motionless feather with wings and a tail. Harry sighed before reversing it back into a normal quill, he closed his eyes and took a deep breath. He opened them and tried again, it took a couple of tries but eventually, he was able to get it right. "Cool." He whispered to himself as he looked at the small brown dragon in his hand, Harry gingerly raised his spare hand and stroked the dragon's back. "I love magic." He grinned. Harry stared at his new dragon, wondering if there was any possible way he could get away with turning some of his relative's things into dragons when they annoyed him.
Magic was undoubtedly the best thing in Harry's life at the moment, which is why he felt it was a shame that he couldn't use it outside of school, even if he did understand the reasoning behind it.
Growing up in the Dursley household, he hadn't known that magic was actually real. His Uncle Vernon and Aunt Petunia had always done their best to stop even the barest mentioning of it, Harry could recall them refusing to let his cousin, Dudley, watch a tv show about magic, no matter how much he begged. In Harry's experience, if Dudley wanted something then he would get it, that was just the way the world worked. The sky was blue, water was wet and Dudley gets what he wants while Harry gets neglected and abused because he's a specky git. And if Uncle Vernon and Aunt Petunia were hesitant, then Dudley would simply ask again or at worse let some fake tears drip down his double-chinned face and they would cave.
But that was one of the few times that they hadn't, simply because they hated magic that much. In the past various weird things had happened around Harry, like the time he turned his teacher's hair blue, at the time he hadn't known that it was accidental magic. But his relatives at least knew that it was magic since they would always punish him more harshly than normal when stuff like that happened.
Eventually, though, everything changed when Hagrid forced his way through the door and told Harry all about the magical world, a world that he was a part of. Entering the magical world was an experience that Harry would never forget, providing that nobody hits him with a memory charm or anything like that. He gained a wand, the ability to do magic, and friends! Though, that didn't mean that there weren't any downsides.
Malfoy and Snape were good examples, the arrogant boy could insult and attack whoever he wanted and seemed to be focused on Harry. Sure some teachers would be willing to give him detentions but most of the time Snape overruled them and took over and Harry didn't doubt that Snape's detention wouldn't ever be worse than a simple lecture before being sent off to bed if you were Draco Malfoy, according to the Hogwarts rumour mill, Snape was Draco's godfather. Though Harry never put much stock in the rumour mill, especially this year.
Snape was a much bigger problem, the man appeared to have hated Harry from before Harry had even known about Snape's existence. Apparently, Snape had a grudge against Harry's father and that had somehow transferred to Harry, not that Harry understood why. Was it somehow his fault for not stopping whatever Harry's father had done to him, even though Harry hadn't been born at the time? Often times Snape acted like Harry's father, James, had raised Harry for the sole purpose of annoying him. Snape was seemingly unaware of the fact that Harry's father had died when Harry was roughly a year old, something that Harry doubted given that the whole wizarding world knew that, Harry suspected it was the far more likely option of Snape just purposely ignoring it because he wanted to continue his stupid little grudge and James Potter was too dead to do it.
Though the biggest problem so far had been Voldemort, the man that had murdered Harry's parents and had tried to kill him more than once since Harry's return to the wizarding world. In Harry's first year, Voldemort had possessed the defence against the dark arts teacher, Professor Quirrell. It was more than a little bit disturbing to learn that the guy who killed your parents was living on the back of your teacher's head.
Professor Quirrell-mort had tried to kill him during his first quidditch match, and once more that year when Harry and his two best friends, Hermione and Ron, tried to stop him from stealing the philosophers stone. The year ended with Harry being able to destroy Quirrell's body thanks to his mother's protection, but Voldemort had managed to escape.
This year had been worse than last year, they had another bad defence against the dark arts teacher in Professor Lockhart, a man who seemed less than competent and spent most of his time staring at his reflection. What made matters worse was that the famous wizard was a fraud who had simply been taking credit for other people's accomplishments and then wiping their memories. Harry had also discovered that he could speak to snakes, unfortunately, the rest of the school found out at the same time and started accusing him of being the heir of Slytherin who was attacking muggle-born students throughout the school.
Between dealing with the majority of the school hating him, Harry also had to deal with Dobby's horrible attempts to save him. Sure, Harry knew that the little house elf meant well, but trying to injure him with a bludger so he would leave the school? Really? Eventually, though Harry was able to find out the heir of Slytherin was actually an old book of Voldemort's that was possessing Ginny Weasley, Ron's little sister, and making her unleash a basilisk that had been hidden in the chamber of secrets.
One wild adventure later had ended with Lockhart being obliviated of all of his knowledge, Harry had ended up fighting the basilisk with just a sword, as one does. Fortunately, Harry had been able to kill the beast, but in doing so he had ended up being painfully stabbed in the arm by one of its teeth. Thankfully Dumbledore's phoenix, Fawkes, had been there and used his tears to neutralise the venom. Not long after that Harry had destroyed the book with the basilisk fang, and a short while later he managed to free Dobby from Lucius Malfoy, Draco's dickhead of a father and the idiot responsible for dropping the book in Ginny's possessions, thankfully ending this nightmare of a year.
Ginny was in the hospital wing with him, currently sleeping in a far corner of the room, under several potions and spells. Apparently being possessed for the majority of the year was a bad experience, who could've guessed?
"Ow!" Harry hissed when he felt something hot near his hand, he quickly pulled his hand back and saw that the miniature dragon had gotten either bored or angry at his lack of attention towards it and had unleashed a small burst of fire. Thankfully he wasn't burnt but he now had to put out the fire that was on his bedsheets, Harry raised his wand but it turned out to be unnecessary since a second later the fire vanished and the bedsheets repaired themselves. "Huh?" Harry intelligently managed.
"That brings back memories," A voice spoke, Harry's head snapped to the side and he saw Professor Dumbledore had entered the hospital wing and was walking towards him. "I remember the first time I had made a dragon, it burnt my chin. I feared that I would never grow a beard ever, though thankfully that worry has proven to be nothing more than a product of fear." Dumbledore chuckled as he stroked his waist-length beard.
"Professor Dumbledore." Harry quickly sat up, taking care to not knock his dragon onto the floor.
"No need to get up, Harry," Dumbledore said before he waved his wand and created a chair for himself, he sat next to Harry's bed. "hmm, that is an adorable dragon," He said, admiring Harry's creation. "though the skin is not perfect and the eyes could do with some work, still, a good attempt."
"Thank you, sir," Harry blushed a little. "it's my first time trying it."
"But I can guess that it won't be your last," Dumbledore smiled knowingly.
"Probably not," Harry admitted as he turned the dragon back into a quill. "I'll probably have to do it again next year, it is a third-year spell, isn't it?"
"Indeed it is," Dumbledore nodded. "I would recommend not practising too many spells in here, Madam Pomfrey doesn't appreciate it, believe me when I say that I know that to be a fact."
"I believe you," Harry sighed, that lined up with what he knew about her. "still, it is boring in here and I needed something to do."
"Understandable," Dumbledore hummed. "anyway, I just came in here to check on you and see if you were okay. I was going to ask Madam Pomfrey but seeing as you're awake…" Dumbledore trailed off and looked at him questioningly.
"I'm fine, sir, honest," Harry answered. "Madam Pomfrey said I have to stay here for a bit more but then I can go."
"Hmm, excellent," Dumbledore smiled. "well, if that's all, I should be off now."
"Actually, sir," Harry hesitantly spoke. "I was… I was wondering if I could ask you for something important."
"Oh?" Dumbledore raised an eyebrow and looked at Harry in a questioning manner.
"Well… I was… I was kind of hoping that I could stay at Hogwarts for the summer." Harry's voice was undeniably hopeful.
"Stay at Hogwarts?" Dumbledore frowned. "What about your relatives?"
"I doubt they'd mind," Harry muttered, Dumbledore had heard him and his frown had increased slightly.
"I'm sorry, Harry, but that's not possible," Dumbledore told him. "Hogwarts has not allowed students to stay over the summer for hundreds of years."
"Oh," Harry disappointedly looked down, Dumbledore was about to speak again when Harry looked up with a slightly brighter look on his face. "that's fine then, I can just stay in Diagon Alley then." He remembered hearing that the paying customers could stay in the Leaky Cauldron and he had more than enough money to pay for a room.
"Harry, I do not think you should do that," Dumbledore said. "you should go and stay with your family this summer." Dumbledore 'advised'.
"But why?" Harry frowned, staring at the old headmaster.
"It would be a good opportunity to improve relationships between yourselves," Dumbledore told him, Harry opened his mouth to protest but was cut off when Dumbledore spoke again. "also it is far safer than staying in Diagon Alley by yourself."
"Maybe, but I'd rather stay by myself." Harry took great effort to keep his voice neutral and stop himself from getting angry with Dumbledore. "I'd rather risk Diagon if I'm honest."
"And I'd rather you didn't," Dumbledore said, his voice may have sounded quite calm but the look on his face was that of a stern teacher. "and I'm sure that you will agree in saying that it would be better for you to stay at the Dursley's." Dumbledore continued staring at Harry who stared back. It was several seconds later before their staring contest was broken by Harry who looked away and looked down at his lap. "It was nice seeing you again, Harry," Dumbledore said in a soft voice, a small smile on his face as he stood up. "I hope your next year will be better than this one." He turned and calmly walked away.
Harry stared at the doors that Dumbledore had walked out of with an intensity that could have pierced through steel, he had barely noticed that his clenched fists were gripping the bedsheets hard enough to almost damage them again. Harry turned his head away and took several deep breaths before he was able to open his hands again.
Deep in the far reaches of space, a small space shuttle plummeted down towards Earth, the outside of the ship protected those inside the ship from burning up upon re-entry, but barely given the damage the ship had received. A few minutes ago everything had been fine, but that all changed when something had crashed into their ship, damaging it enough that they were not able to stay up for long. Inside the ship were four panicking astronauts that were doing their best to try and stop the ship from crash landing and killing them all, it might have been a state of the art vehicle but there was no way that it would survive a crash if it dropped from space directly to the ground at the speed they were currently going.
"Damn it!" One of the astronauts cursed. "We need to slow down!"
"Working on it!" Another one shouted, frantically pressing buttons and pulling levers in such a way that one who had no idea how the ship operated would assume that he was pressing them randomly. "Fuck me, this is terrifying!"
"We know!" A third astronaut shouted.
"The ship's hull has been penetrated!" A fourth astronaut yelled.
"No shit!" The first one yelled out. "We're off course!"
"We got bigger problems! Like, survival!"
The astronaut, so busy with their crashing ship and arguing with each other, didn't notice that the door behind them creaked slightly open, nor did they notice black goo that sneaked into the control room.
Chapter 2 - Eight legs to two legs
A loud crashing sound was heard in the countryside as the spaceship crashed into a mostly empty field, the few cows that were in the area scattered upon hearing and seeing the large crash that had caused a fairly big crater to appear in the field. Inside of the damaged and broken ship the astronauts were scattered around, unfortunately only one of them had managed to survive.
He groaned as he lifted his face off the ground, his eyes widened to almost comical levels when he saw the rest of his crew lying around him, bleeding and with broken bones. He had no doubt that they were dead, especially given the way that their necks weren't the same shape as they were before the crash. He grunted as he forced himself to his feet, or at least he tried to before realising that he had broken his right leg.
"Damn," He looked at his leg, he was pretty sure that the bone sticking out of his leg was not normal. "now what the hell am I supposed to do?" He wondered, shaking his head. He paused when he heard a noise behind himself, he turned and gasped when he saw a pile of black goo right next to him. "What the… AARGH!" The goo cut him off by lunging at him, he screamed as he both felt and saw the goo disappear into his body. he took several panicked breaths before looking around. "Huh? Huh, hmm… I'm… I'm alright, nothing happened." He grinned with relief, unfortunately, his relief only lasted a few moments as shortly after he felt himself control of his body.
The astronaut gasped loudly, his body convulsed before he went limp, he fell face-first to the floor. A second later the black goo poured out of his body and slithered away, highly disappointed. The organism it had just left was an incredibly bad match, so bad that it hadn't stayed for more than a few seconds. It had stayed long enough to learn basic knowledge about this world.
Apparently, it was on a planet named Earth, populated with hundreds of different creatures, but the strongest creatures on this planet were no doubt the humans. Not physically the fastest or strongest, but they possessed a special type of cruelty and ingenuity that not all beings possessed, or at least some of them did. It decided that the best thing to do would be to keep moving, if it stayed too long then it was entirely possible for it to be captured by the humans that were no doubt going to come and investigate. It was possible that it could end with bonding, but more likely that the humans would lock it up and experiment on it.
The black goo slithered out of the crashed ship and continued moving until it left the crater and reached soft grass. It stopped for the briefest of moments before it continued moving until eventually, it came across another living being. A fairly big spider, deciding that even a small host was better than being out and exposed, the goo leapt towards the spider. The comparatively smaller creature tried its best to escape but the spider just wasn't fast enough.
The goo shrunk down and formed a second skin around the spider before taking control of the arachnid, it forced the spider to turn and then started using its control over it to make it run as fast as it could, which was a lot faster than normal thanks to the goos help. The goo had been able to learn from the astronaut that while animals had varying degrees of intelligence, it was humans that would fit it best.
Animals were far less complex, only concerned with survival and eating and other simple needs, humans were different, more emotional. They had wants, desires, feelings, perfect feeding for a creature such as itself. They wouldn't be easy to control, but they would taste so good. It had to get to a human, if it was careful then it would eventually find a good match. For the goo, the spider was the equivalent of having a bland biscuit to tie you over when you were hungry, not great but good enough until you get some real food.
It wasn't sure how long it took, but eventually, it came near some houses. Once close enough it disappeared into the spider, reducing the chance of being caught but still controlling the spider. It wasn't long before it spotted a human, but this one didn't look like a particularly good fit. Plus her voice sounded quite annoying.
"Oh, there, there," The overweight woman cooed as she bent down and roughly petted the dog in front of her. "I'm not a big fan of leaving the countryside either, but we haven't visited my brother in ages." She was apparently talking to the dog, it was hard to frown with pincers but somehow the possessed spider had managed it. On the one hand, he wanted far away from the irritating woman with the habit of talking to animals as if they could understand her, but on the other hand, this woman said she was leaving the countryside. It was possible that she was going somewhere more populated, giving it an increased chance of finding a new host.
A minute or so later a decision was made, the goo left the spider, allowing it to fall dead. The goo moved forwards, climbing up a nearby tree, it waited until the obese woman had turned away, then it leapt through the air and landed on the dog. The surprise the dog felt prevented it from being able to even attempt to stop it from taking over. The goo couldn't help but feel disappointed with the dog, it had the necessary tools to allow itself to be great, yet was content with being babied by the woman and had let itself become weak.
"Ripper, are you alright?" The woman asked the dog when she noticed it hadn't followed her like normal, after a moment she saw and heard Ripper bark at her before he began following her. Dismissing what just happened, assuming that he had just gotten distracted by something, she went towards the house to collect her belongings so she could go and visit her brother and his family.
It was a very long journey later that Ripper, the possessed dog, arrived in the Dursley's house followed by the woman that owned him, though the goo inside the dog had not enjoyed the trip much. Honestly, how could one woman fuss so much over a creature that only needed food, water and some entertainment? One would have been forgiven for thinking that the dog was a newborn baby with the way that the woman was treating it. Once inside the house, the dog followed the overweight woman into the living room.
"Hello Marge," A voice said, and the possessed Ripper took the opportunity to look around the room and see what it was working with, he paid attention as Marge (the insufferable woman he was unfortunately with) began conversing with the people in the room. Greeting the woman was an obese man, even fatter than the woman, with balding hair and a large moustache. Apparently, he was the woman's brother, a man called Vernon Dursley. Along with the man was a blonde woman that would be noticeably skinny, even without standing with the two other overfed humans. The woman was called Petunia and was Vernon's wife. The third human was sat down, watching TV without a care in the world, not even responding to Marge hugging him and fussing over him. The fat, blonde-haired boy, was the unfortunate result of coitus between Vernon and Petunia and was called 'Dudders' or 'Dudley', the goo was pretty sure that one of those was a nickname.
"You're still here, are you?" Ripper heard Marge say to someone else in a less than friendly tone. Ripper turned and saw a boy standing in the hallway outside of the room. He was dressed in clothes that seemed to be too big for him, he had rounded glasses that didn't look all that cared for, unlike the rest, he had messy black hair and bright green eyes.
"Yes." The boy said shortly.
"Don't say 'yes' in that grateful way," Marge glared at him. "you are lucky that my brother was nice enough to keep you." Ripper paid close attention to the boy as Marge continued to rant about how ungrateful the boy was. The creature possessing the dog had access to the dog's memories and could call up memories of chasing and attacking this boy when he was younger, the boy was called Harry Potter, but the Dursley family preferred to call him 'freak'. It could see the boy restraining himself as Marge continued speaking, it could see the way that the boy wanted to lash out and how he did his best to prevent himself from doing so.
'Interesting,' It thought to itself. 'the boy shows plenty of promise, who knows how many emotions he was holding back?'
"Take Marge's luggage upstairs," Vernon ordered the boy.
"Yes, Uncle Vernon." Harry obediently nodded before picking up Marge's stuff with barely a sigh. He turned and began carrying them up the stairs, 'does it have to be so bloody heavy?' he thought to himself. Harry knew that he was never going to be the strongest kid on the block, his lack of food and living conditions at the Dursley's had seen to that, but he couldn't help but wish he was at least a little bit stronger while he carried Marge's suitcase up the stairs. 'Either I'm weaker than I thought or this suitcase is ridiculously heavy, what weighs so much in here, anyway? Her underwear?'
Soon enough Harry had gotten her suitcase into the room that the Dursley's had set up for her, or rather the room that they had forced Harry to set up for her. Harry was honestly quite tempted to just stay upstairs for the night and avoid Aunt Marge, the woman who had always hated him. Harry wasn't really sure if that was only because of what Uncle Vernon and Aunt Petunia had told the woman, or because of other reasons as well, but it didn't matter in the end since the hatred wasn't a one-way road because Harry was about as fond of her as he was of the rest of the Dursley's. Sadly, however, Harry knew that if he wanted to get the school permission slip to go to Hogsmead village signed then he needed to behave.
He turned around, only to freeze when he saw Ripper standing in the doorway, the dog that usually chased him or ate everything in sight was dead still, staring at him with unblinking eyes. Harry couldn't help but frown as he took a step back before realising he had, he stared at Ripper who stared back.
"What do you want?" Harry asked before his frown deepened slightly. He didn't know why he had asked that question to Ripper, perhaps his experience with Hedwig and Fawkes had changed the way he treated animals but he had to remember that Ripper wasn't as smart or kind as them. Ripper's head tilted to the side but he didn't say anything.
"Boy!" Their little staring contest was broken when Harry heard Uncle Vernon bellow. "The food isn't going to cook itself!" Harry stared at Ripper for several more seconds before he cautiously moved forward and gingerly slipped past Ripper before heading down the stairs, with Ripper's eyes focused on his retreating back.
Ripper had paid close attention to Harry Potter as dinner went on, he noticed that his constant staring had made the boy uncomfortable so he shifted to discreet glances instead. He saw the way the boy's relatives made him work as if he was a private waiter and chef, he was pretty sure that it was not normal to treat someone Harry's age like that, at least not in this part of the world. The Dursley couple and their son seemed content with ignoring his presence, but Marge was an entirely different game and had insisted that he be in her sights at all times.
He wasn't quite sure why Marge insisted on antagonising the boy, but she did. If she didn't criticise the way that the boy worked then it was the way that the boy behaved or the way that he looked or any other number of minor and major complaints that she could come up with. The creature inside Ripper was honestly staggered that the boy hadn't reacted by now and done something, it could tell that the boy's limited patience was waning and all that would be needed was a big push.
Something that Marge was more than happy to provide.
"You see it's nothing to do with the father, it's all to do with the mother," Marge said after several minutes of complaining about Harry's father being a drunk, she eyed Harry who was carrying a plate away from the table and smirked at his back before turning back to Vernon and Petunia after taking a long sip of wine from her glass. "you see it all the time with dogs, really, I've seen it plenty of times. I've had to put a few down because of it, it's just the way it is. If there is something wrong with the bitch then there is something wrong with the pup."
"Shut up!" Everyone in the room turned to face Harry who had apparently reached the end of his patience, having thrown a plate hard on the floor, causing it to shatter into pieces. Harry was glaring intensely at Marge, his fists shaking as if he wanted nothing more than to go over to her and punch her in the face, his breath heavy and hatred on his face. "Shut up!"
"Right," Marge grinned as she turned to face Harry. "let me tell you something, boy, your mother was just a simple…" Marge trailed off as she suddenly felt quite weird, she looked down and her eyes widened as she saw her hand had begun bloating along with the rest of the body.
Ripper watched with fascination as Marge Dursley blew up until she looked like a balloon, the other Dursley's stared at her with horror as she began floating up into the air. Ripper looked towards Harry and watched the various emotions that cycled through his face, including anger, confusion and realisation, but the first seemed to be the most consistent one. Harry rushed out of the room while the Dursley's tried and failed miserably to stop Marge from floating away into the sky, meanwhile, the goo inside Ripper had made a choice. It wasn't sure how, but it knew that Potter was responsible for what had just happened, he had done something to Marge. Its limited knowledge of humans let it know that that was not possible, yet Potter had somehow done it.
The goo was a member of an alien species known as the Klyntar, or 'symbiotes' as they were more commonly called, a species that feed on a couple of different things, one of which was emotions. The more powerful the emotion, the better, and Potter looked like an all you could eat buffet. The symbiote was leaning towards attempting to bond with Potter before, but seeing that display had made it even more sure that that was what it wanted. It made Ripper's body move and follow Potter up the stairs, it peaked into the open door of Potter's room and saw Potter packing after releasing a snowy-white bird out from his window with instructions to find him later. It decided that now would be the perfect time to change hosts since Potter was distracted and the rest of the Dursley's were busy with Marge, Ripper moved into the bathroom and the symbiote left the dog's body, not caring that Ripper died a second later.
The black goo made itself as short as it possibly could just as Potter had come out of his room whilst holding a trunk, the symbiote rushed out once Potter had walked past the bathroom and quickly jumped onto Potter's suitcase. They had started going down the stairs when Vernon and Petunia Dursley returned, the symbiote cursed them for their bad timing before it quickly went inside Potter's trunk through a small hole near the top.
"You bring her back! Bring her back now!" Vernon Dursley ordered Harry as soon as Harry had gotten down the bottom of the stairs.
"No, she deserves what she got and as far as I'm concerned she can float off into space!" Harry snapped, "the only problem I could see would be if she ends up blocking the planet's view of the sun." Vernon let out a bellow and was about to charge at Harry but stopped when Harry pulled out his wand and aimed it right at Vernon's neck. "No, go on, I've got over years worth of reasons to do it." Harry glared at him.
"You… you can't do magic outside the school," Vernon reminded him as he took a step back. "you've nowhere to go," Vernon added, looking somewhat confident despite the way that his face had paled.
"I don't care, wherever I go will probably be better than here." Harry turned and quickly rushed out of the house before his relatives could stop him.
Harry shook his head, cursing the name 'Dursley' as he stopped by the local playground. He hadn't really thought of where he was going to go, he just wanted to get out of the house. He stopped, deciding he needed a moment to calm his head.
"What am I supposed to do now?" He wondered to himself, he supposed that the best option would be to stay at the Leaky Cauldron for the rest of the summer. He needed to buy his school supplies anyway, plus he didn't really mind staying in Diagon Alley. Now, there was just the question of how he was going to get there. He had some muggle money with him but he wasn't sure if it was enough for a taxi.
"Woof." Harry's head snapped towards the bushes on the other side of the road, he saw something creeping out of the bushes and instinctively raised his wand. He watched as a big dog with midnight black fur stepped out and stared at him, meanwhile the symbiote snuck out of his trunk. Harry wasn't really that fond of dogs, the only good dog that he had ever met was Hagrid's dog, Fang. Hagrid's other dog, Fluffy the giant, three-headed dog, had tried to eat him while Ripper would nearly always attack him. The dog opposite him looked a bit skinny, but that didn't mean it didn't look intimidating, especially this late at night.
The dog barked loudly just before a large bang sound was heard coming from Harry's right, Harry looked in the direction of the sound and saw a purple, massive triple-decker bus charging towards him. Harry took a step back to avoid getting run over, he felt the back of his feet connect with the curb and he tripped backwards, hissing in pain as he landed on his back and on top of a rock that dug into the spot in-between his shoulder blades. Between the pain, the bus, the massive dog and the leftover emotions from his confrontation with the Dursley's, Harry didn't quite notice the symbiote sneak into his body.
