I don't know if this needs much intro that won't be explained in this first chapter... Hiccup is adopted... Modern AU... Hiccup will be referred to as Henry once at the very start but definitely still Hiccup... everything else you can pick up on the way.

Oh, one more thing..

WARNING - this story will in the future contain Hiccup/Valka incestuous stuffs. In case you don't know what Valcup meant.

-HTTYD-

Screeching brakes. Metal smashing into metal. Glass shattering. His family screaming... and a blinding pain in his leg as he smelt smoke. Henry reached for his parents in the front seat, but they weren't there. He was trapped, alone and the flames were getting stronger...

Henry 'Hiccup' Hofferson bolted upright, sweaty and shaky with phantom pains where his leg used to be. Twenty seconds later his bedroom door opened, revealing Astrid and Toothless.

"Hiccup?" Astrid had called him that since childhood "nightmares again?"

"Did I wake you again? I'm s-sorry."

His sister sat on the bed, grabbing the pack of wet wipes on his grooming table on the way and wiping his clammy, sweaty face. Their dog leapt up, a small and scruffy black mutt that as his name suggested, lacked most of his teeth. He nuzzled Hiccup's limp hand, demanding attention.

"Stop apologising you dolt. Wanna talk about it?"

Hiccup shook his head, watching as Astrid dug out a fresh t-shirt for him to swap for his sweaty one, tossing the soaked one in the wash basket and shoved her way into his bed. Toothless slumped on his other side, ensconcing Hiccup with warmth and affection.

"Get some sleep bro."

At seventeen, he felt silly needing his little sister to come chase away the nightmares. But then, Astrid was practically a Valkyrie, she would take up an axe and shield to physically defend him from them if she could. Hiccup felt a little better, falling asleep and not being revisited by the nightmares.

They woke to Hiccups alarm, which meant it was time for Astrid to get ready for school. Barely a year apart, Astrid was in the year below him and Hiccup had already finished school. He had planned to go to college, but that was before...

He was now Astrid's guardian, some social worker checking in on them every week after the two fought not to be removed from their home. The home they had shared with their parents, before their mother and father were killed in a car accident. The same one Hiccup still got nightmares about, the one that had also taken the lower half of one of his legs.

Astrid grumbled when Hiccup prodded her awake, sitting up with messy flyaway hairs escaping her hair braid.

"I hate mornings."

"You know they are watching us. It's either stick to the routine until you finish school, or Uncle Spite moves in."

"I know. You need a leg rub this morning?"

Hiccup stretched his legs, then shook his head. Astrid hated his physio, so she had learnt how to do the massage for his leg stump. His sister was awesome.

"Go let Toothless out, I'll come make your breakfast and lunch when I've been to the bathroom."

"Mkay. Come on Toothless. Here's your leg."

Astrid handed him his prosthetic, then rolled off his bed and padded off in her pyjamas, dog following eagerly behind her. Hiccup attached his leg, took a few ungainly colt steps to adjust to having it on and headed for the bathroom. Their house wasn't lavish, but certainly comfortable - their parents had come from money, one of the reasons Hiccup and Astrid had been allowed to remain there with no working adult to support them financially.

That didn't mean it was easy, learning how to run a household while reeling from their parents death and Hiccups injury, but the two of them and Hiccups therapy dog - Toothless - were beginning to muddle along after six months now.

If only Hiccup could shed the nightmares.

Astrid dropped into her seat in a clean, ironed school uniform, inhaled her bacon sandwich and held up her bag jokingly for Hiccup to check. He gave it a cursory check, then grinned and turned to the side.

"Peanut butter or chocolate spread?"

"Both."

"Two sandwiches or both fillings?"

"Two sandwiches, I'm always hungry!"

Chuckling, Hiccup made up both sandwiches, added an apple, a bag of melon and grape chunks and some water, then gave Astrid her weeks pocket money to buy whatever unhealthy extras she wished. So long as she ate her fruit and vegetables, he couldn't force her not to have the occasional fast food or chocolate.

"Ok, lunch ready. Any school trips?"

"No."

"Homework done?"

"Yep."

"All your washing in the basket?"

"Think so."

"Do you need me to pick up anything from the shop? Tampons? Condoms?"

Astrid rolled her eyes at the mention of condoms. Hiccup had had to get over any embarrassment now he was the adult of the house - if Astrid was due her period, he would pick up her stuff while she was at school. That was responsible.

"Hilarious! What am I gonna do, use them as water balloons?"

"Just checking."

"I'm not due til next week, you'll go twice more by then and I still have the emergency ones I keep in each bag and coat. I'm good."

Nodding, Hiccup tapped a pen on his notepad while he thought about what they needed from the store.

"We could do with more popcorn and cans of pop. Heather's coming over for a movie tomorrow night."

Heather was Astrid's girlfriend, and Hiccups ex. They were that adult about it, when Heather and Hiccup broke up because Heather realised she was gay, and when Astrid came out they started dating. It was fine.

"Is Dagur coming?"

Dagur was Heather's older brother, but he was easy company for Hiccup - nothing really fazed him, he didn't blink if Hiccup fell over learning to walk on his prosthetic, just lifted him up onto his feet again.

"Probably. I expect their dad will come over, looking for mess and chaos."

"Alright. Better pick up some jerky for the beast that is Dagur."

He noted it on the list, checked they weren't due a social visit that day in case he missed it while out, then grabbed the car keys.

"Ready to go?"

"Yep."

Astrid hopped off her seat, downed her fruit juice and grabbed her bag. Hiccup dropped her off at school, waved to Heather from the car, then drove over to the supermarket. Picking up the usual essentials, hoping nobody recognised him and came over while he was limping about to try and be a grown up, to try and keep functioning for Astrid's sake.

It was not to be.

"Henry!"

Gritting his teeth as he picked up a box of eggs, he turned toward the voice and saw Heather's mother. She was a lovely woman, but Hiccup wasn't in the mood.

"Hey Mrs B."

"How are you doing lad?"

"Oh, you know. Trucking on."

She gave him that sympathetic look, the one he hated. He didn't want everyone lamenting it all day every day. That was for he and Astrid, for the people they chose to share it with. Heathers parents were overbearing, but Heather and Dagur were their friends so it wasn't easy to shake their parents.

"Hows Astrid getting on at school?"

That made him feel like a parent. He had to fill that role, and it was tough.

"The teachers only have good things to say. I better get going, got stuff to do yanno."

"Of course. You let us know if you need anything! I'll send some food over with the kids tomorrow."

"Oh, that's not nec-"

"Nonsense! It's no trouble. I'll see you lad."

Escaping, Hiccup finished shopping, ignored the look of the cashier working out how young he was and thanking the gods for his disabled drivers badge. It meant a tiny walk to load the car, then he could collapse in the car. His heart hammered, sweat beading on his neck as he drew in shuddering breaths that didn't fill his lungs properly.

His therapist swore anxiety was a perfectly normal response to what had happened to them, but every weakness made Hiccup dread that he wouldn't be seen as fit. That they would be split apart, or that their uncle would get away with coming in and taking control of the family money - he didn't care much for his niece and nephew, but Spite wanted the family inheritance badly.

Eventually, the panic attack passed. Hiccup started the car, driving back home and going through the motions. Unpacked the shopping, loaded the washing machine, the dishwasher. Cleaned the kitchen, tidied up about the place then clipped on Toothless' harness and leash.

"Let's go for a walk bud."

The dog knew Hiccup wasn't fast or strong, walked nice and sedately as they traipsed to the nearby field. Hiccup let him off the leash to run off, bolting around to get the excercise he needed while Hiccup plopped down on the bench to watch him.

"Oh my gods, is that your dog?"

A child of about four gushed, their parent right next to her as Hiccup nodded.

"Yeah, he's mine."

"Can I pet him? Mommy said always ask."

"Sure, but he drools. He's got like, no teeth."

"That's ok."

Hiccup whistled, Toothless rushing back to him excitedly.

"This is Toothless."

"Hi Toof-less! I'm Amy. He's so cute!"

Toothless loved any and all attention, panting happily as the girl ran small hands through his shaggy fur.

"Come on love, we need to go."

"But the doggy!"

"We come down here almost every day, so you can see him some other time if you're around."

Amy pouted, but she eventually realised her mother was looking frustrated and sighed.

"Okay. Bye Toofless!"

Toothless went back to his excitable tearing about the field, wearing himself out and investigating lots of grass and plants. Hiccup watched them go, just glad to have been a normal guy walking his dog to somebody at last. It was refreshing, cathartic. Clipping the leash back on, Hiccup and Toothless headed home.

He gave Toothless a bath (and inadvertently, himself when the dog shook off), and then it was time to go pick up Astrid from school. She hopped in the front seat, tossed her backpack in the back seats and fastened her seatbelt.

"Do we have therapy tomorrow?"

"No, day after. You have the dentist next week too."

"Ugh, I cannot wait to be out of school so our lives are no longer dictated by a woman who smells like a barrel of cod livers. Then I can skive the dentist like everyone else."

"Thank you for that disturbing mental picture. Ready to go?"

Astrid kicked off her shoes and leant back in her seat, nodding. She emptied the dishwasher, he moved stuff from the machine to the dryer. There had been accidents back when they were just learning - white clothes turned pink by Astrid's favourite red t-shirts or Hiccups black jeans, putting washing machine tabs in the dishwasher by mistake and covering the utility room in bubbles and having to clean everything by hand or their food would taste of jasmine detergent.

Now they were getting it down - Hiccup started dinner while Astrid sat at the table doing her homework. They watched some TV, drank hot chocolate and had a vicious game of Monopoly. Astrid forcibly put him on the sofa and Toothless on his lap, then gave his leg stump the massage it needed but he hated asking for.

"Uniform out?"

"Yep."

"Room tidy?"

"Yep."

"Honestly? We have a social worker visit tomorrow."

A sheepish Astrid pouted.

"I'll sort it."

Hiccup let her have her space - he didn't go in her room. Her wash basket was on the landing. Astrid only came into his room if he had nightmares that woke her.

"Alright. Lunchbox in the kitchen?"

"No. Hang on."

Astrid vanished in her room, then came back holding the empty box.

"Here."

"Ok. Homework finished, vegetables eaten, adequate food in cupboards... we should be good for tomorrow. Go tidy your room, then get to bed."

"Dictator. Love you bro."

She kissed his head, then ruffled Toothless' fur and headed to ensure her room was clean for the social worker the next day. Hiccup rinsed her lunchbox and laid it on the drying rack, but he was too pent up to sleep. He puttered around the kitchen, mixing ingredients for a chocolate cake.

"I smell cake!"

"It's for tomorrow! Go to bed!"

Astrid growled from her room, but didn't come out . Once it cooled, Hiccup iced the cake and put it in the fridge to set. Cooking always relaxed him. Checking absolutely everything was clean again, that he had everything for Astrid's breakfast and lunch, Hiccup let Toothless out for a pee, then took a quick shower on his water-proof leg (he didn't love the look of it but the other one slipped in the bath) before crawling into bed.

He heard Astrid continue to putter about in her room, tidying up before the old crone came to investigate them for a single sign Hiccup wasn't taking sufficient care of his little sister. She seemed personally offended by the idea the two teens could be self-sufficient, especially with Hiccup's disability.

They went through it all again the next day, Astrid promised her room was clean and Hiccup loaded Toothless into the car with them, driving him out to a bigger field after he dropped Astrid off at school. Toothless tore around, wore himself out and then hopped agreeably back in the car. Heading back, Hiccup ran the mini vacuum over the hair-covered back seat though trying to master Toothless' moulting was a fruitless endeavour.

He and Astrid both ensured they were dressed smartly, that everything was spick and span, just in time for their evil social worker to rap on the door.

Bertha was a big woman, take-up-the-whole-doorway big, with a mean scowl and a sharp tongue. That day she had a trainee with her, a tiny lad who peered around her and introduced himself as Gustav.

"Call me Gus."

"I'm Hic- Henry. This is Astrid. Look around all you want, everything is to standard. Don't mind Toothless, he literally cannot bite you."

Bertha trampled around, thundered up and down the stairs searching every single room. Gustav investigated the cupboards, saw Hiccups daily check list, the fridge with Astrid's exam dates, dentist and doctor contact info and their therapy appointment cards all stuck on with dragon-shaped fridge magnets.

"Therapy?"

Bertha barked the question at them, chunky silver pen held over her clipboard.

"Joint therapy weekly, Astrid has solo therapy weekly also. I have it twice, for PTSD and for grief."

The thing that annoyed Bertha was that every expert and psychiatrist who spoke to Hiccup had said he was exceptionally functional and absolutely capable of taking care of Astrid. Everyone had also said Astrid was remarkably bright and happy, healthy and clearly cared for.

"School?"

"Astrid has not missed one day all month. Here's the attendance report to prove it."

Scowling, Bertha took the report and scanned it, then shoved it back.

"Any other problems?"

"None."

Astrid grew irritated with being talked about like she wasn't there.

"My brother is doing a brilliant job, you know he is even if you don't like it."

Bertha huffed, knocked young Gus aside and tossed a couple of envelopes on the side.

"For your upcoming birthday. Hearing to determine competency and all that rubbish."

"Hey wait, that one is-"

"Be quiet Gustav. Same time next week."

"We can't. Astrid has a basketball game. I'm going to support her. Here's our schedule, pick any of the blank spots."

If anything, her scowl deepened as she practically snarled.

"Friday. Four thirty."

As if by magic, Dagur and Heather were at the door. Hiccup opened it happily, the two coming in clutching boxes of pre-made meals from their parents.

"Hiccup!"

"Hey guys. Come on through. Heather, Dagur, this is our social worker and her assistant, Bertha and Gus."

"Oh. Hi. Should we wait-"

"No, they were just leaving."

Hiccup said with relish, watching a muscle in Bertha's cheek twitch with suppressed anger. Gus smiled at the visitors, checking something on his clipboard.

"What's that?"

Bertha spat. Gus visibly recoiled from her tone, but kept his voice even.

"Visible support network. These two are here with food, even though its clear Henry is on top of it. It's just a nice bonus to an already capable man."

"You don't decide that! Come along Gustav."

Hiccup watched the psychotic bitch leave, then he and Astrid both immediately threw off their smart shirts. Heather looked like Christmas had come early.

"Who is that she-devil?"

"Bertha? Eh, she hates that I've never slipped up. She obviously doesn't think a teenager can take care of a house and his sister. Anyway, enough about her. Anyone for cake?"

Dagur helped Hiccup put away the food in the fridge and freezer, then the two girls cuddled up on the big armchair snugly while the two boys took the sofa, eating cake and drinking coke while they watched movies and played games.

"Hey Hiccup, what are these?"

The redhead asked, helping Hiccup load the dishwasher while Astrid and Heather had vanished off to her room rather suddenly. He was indicating the stack of envelopes on the side.

"Uh, stuff for when I turn eighteen. I have to redo the hearing to check I'm alright to take care of Astrid, as they could take her before she turns eighteen if they are worried I'm not supporting further education or employment for her."

"Ah."

"I better go through them actually, put dates on the calendar for Bertha to snoop through."

Dagur chuckled, finishing up the dishwasher while Hiccup started on the letters. Most of them were expected, one appointment to check he was on top of everything since the accident, another to ensure they kept financial control when Hiccup turned eighteen and the third was a complete hearing to ensure Hiccup was taking care of Astrid.

The last one was unusual. It had a different postmark on, and the name was wrong - "Harry Haddock". The address was correct though, so Hiccup opened it to see if it was an error or if it was someone elses letter.

He was stunned. He sat in silence for so long Dagur started to worry. Nudging his shoulder, Dagur looked at him with a concerned face.

"What's wrong buddy?"

Hiccup held out the letter, only able to say two words.

"I'm adopted."
