Warning(s) spoilers for the entire Harry Potter series, spoilers for Avengers (2012) possible.
Notes Hogwartvengers is an alternate universe in which the Avengers characters went to Hogwarts. I just wanted to start writing up the little stories I thought up when presented with the AU concept. I plan to stash them all under this fic title so they'll be easy to find and won't clutter up my when I crosspost them there. There will be a continuity to all of my drabbles. I don't plan on writing any that will contradict one another, though they will not occur in chronological order. I added in some X-Men characters to fill in some professorships and so forth.

Drabble Notes Yes, I look at those warnings and wonder what is wrong with me too. This was ideally going to be written up in a few hours and be a couple hundred words and probably rated PG. Suddenly, the more I wrote, the longer and more dangerous it became.

The Debt

There were two sets of dressing rooms near the back of the Hogwarts Express. The rooms were behind the last compartments, enchanted to be large enough to hold at least fifty students each at a time as well as keep genders separated. It was January and the train was not as crowded as it was at the start or end of the school term. The last boy to step out of the dressing room was a fourth-year Hufflepuff named Clint. The last girl was Natasha, a first-year Slytherin who was just a little shorter than him. They converged on the corridor between the dressing room entrances simultaneously. Clint awkwardly let her enter the corridor first. Second later, all the lights in the Express flew away and the train lurched to a halt. Both students looked to what windows they could see. A group of figures in violet hoods boarded the train. Clint and Natasha could hear the train whistle before resuming its journey, however, their car remained stationary.

Natasha stepped forward to head back towards her friends, but Clint grabbed her wrist and dragged her into the last compartment. It was unoccupied. "We've got to change ties and robes," he said after closing the compartment door and dropped her arm.

"Weird wizards are boarding the train," Natasha said. "I will not be groped. They looked," she tried to think of the right word, "wrong."

Clint stared at her like he just assumed all first-years were innocent. He loosened his tie and pulled it over his head. "I don't want to grope you. I just need your tie and your robe. Not the rest of your clothes. Do you know who they are?"

"No," Natasha said. Her eyebrows furrowed. She had the faintest Russian accent as though she practiced to get it as minimal as possible without losing it entirely.

Clint took off his robe. He held the robe and his tie out to her. "They're a group seeking revenge against purebloods. I don't know all the details, just to beware wizards in violet hoods."

"Revenge for what?" Natasha slowly loosened her own tie and took off her robe. She exchanged the garments with Clint. His face was so earnest and the hush on the train disquieting that she could not hesitate longer in complying.

Noise erupted from the forward area of the car. The distinct sound, smell, and feel of magic entered the atmosphere. Clint knew things would move closer to them soon. "I'll explain later," Clint said. He pulled on Natasha's robe. It was the exact same size as his own robe and clearly almost a size too small for him. His robe fit Natasha perfectly.

"These clothes…. You are a muggle-born or live with muggles," Natasha noted. Any other type of wizard would have had someone near them who could have spelled the clothes larger.

"Yeah, well, they don't have to know that," Clint said. He glanced at the door. It sounded as though things, possibly people, were falling to the floor in the corridor. He looked back at Natasha and spoke quickly. "They'll see that I'm a Slytherin and just assume my politics or heredity. There aren't any famous pureblood Hufflepuffs with redheaded daughters our age right now, so try not to tell them who you really are." He fastened Natasha's robe so it covered his vest completely. Natasha fastened his robe up over her own vest.

"I'm Na –"

"Later," Clint said. "If I don't know who you are, they can't find you. You can tell me when this is over."

Natasha smoothed out the robes carefully. She could hear the compartment doors opening. They wizards in the violet hoods grew closer. She did not jump when the door to their compartment opened.

Clint, out of habit, reached into the sleeve of his robe for his wand. He found Natasha's instead. It would have to do. "Ex –"

A wizard in a violet hood sent a white shock of light towards Clint. It hit him square in the chest and Clint fell to his knees. "Thought you could bargain with some poor girl?" the wizard asked Clint. "Expelliarmus!" The wizard stuffed their wands into a special container strapped to his waist. Clint could not reply against the stinging sensations permeating his chest and throat. The wizard watched Natasha, gauging how much of a threat she was. Natasha tried not to meet his gaze. Once satisfied, the wizard reached out and hauled Clint to his feet.

Natasha met Clint's eyes. He managed to shake his head. He did not want her to follow. Natasha waited for the wizard and Clint to leave the cabin and then followed, sticking to the darkness. She knew the Express had to be close to Hogwarts now. This could not last too long. Certainly the professors would notice that the train missed its last car.

The wizard holding Clint dropped Clint on top of some other petrified or stung students in the corridor. He joined the other wizards dressed similarly in keeping the group of singled out students at bay with various hexes. None of them resorted to any of the forbidden curses. The majority of students were Slytherin, though there were pureblood representatives from Gryffindor, Hufflepuff, and Ravenclaw as well. Students of other wizarding blood types were also a part of the bodies on the floor, representing those who tried to fight back. The attackers planned this event and took time and types of students they might encounter into account. Natasha could see them consulting time pieces.

Clint tried to assess who was around him in the minimal light. His eyes met Thor's eyes. Thor was younger than Clint and from the famous pure-blood Odinson clan, very rambunctious, and good at dueling. Thor still looked hopeful. Thor's younger brother Loki looked exactly the opposite.

"When we were children," one of the violet hoods spoke, "Death Eaters came into our world." His hood moved towards the wizard with the time piece. He then looked back at the students and stuck one of the Ravenclaws in the side with the tip of his wand. "They showed us magic. They showed us its destructive nature. They showed us an extermination plan.

"Well, we've experienced their world and we have decided to offer a declaration of our own," he said.

The wizard with the time piece made a gesture with their hand.

The vocal wizard raised his wand. "Incendio," the wizard whispered.

The flames originated in the center of the pile of students. Student regaining their ability to vocalize shrieked in pain. Clint could feel the flames approaching. Thor rolled, trying to block Loki, Clint, and whoever else he could shield from the flames as much as possible. Many of the other students on the floor, still count not speak or move adequately. The fire moved with a life of its own, careful to avoid the face or any body part that was too tender. It was a message, not death.

A loud bang sounded overhead. Natasha crouched down low in her hiding place and watched as Headmaster Fury dropped down through the emergency exit in the ceiling of the car. With a swish of his wand, Fury extinguished the flames.

Clint felt disoriented. He had some feeling in his hands and shoved Loki's elbow away from his stomach. He eased himself up as much as he could, wanting to get out of the way as professors descended into the car to aid Fury against the violet hoods. He propped himself up on an arm just in time to get the brunt of a hex aimed at one of the professors nearby.

When Clint woke, he was in the hospital wing. He felt fingers hesitantly touch his uninjured hand and looked over to his left. Natasha's lips moved and he shook his head. Natasha gestured for the nurse to join them.

Jean Grey was the nurse at Hogwarts. She carefully assessed Clint before handing him a box. It was clearly muggle technology powered by magical intervention. Clint glanced at Natasha briefly before opening the box. He removed the hearing aids inside and put them in his ears. With a few flicks of his wand, he had them calibrated.

"Thanks," he said to Nurse Grey. He looked around the hospital wing. He could see several other students being treated for severe burns. Loki was in the bed beside them and Thor sat careful watch despite being the more injured of the two. A small noise brought Clint's attention back to Natasha. She had her proper robe and tie on now.

"I owe you," she said quietly once his gaze met hers. Her hands rested in her lap now. She was completely uninjured.

"No you don't," Clint said. He held up his hand that was wrapped in bandages covered in a special potion to heal his wounds. "This isn't my dominant hand."

"Yes, I do." Natasha's voice was firm and her resolve unwavering. "If you let me go back to my friends, I would be where you are or worse. I am in your debt."

Clint looked at her. He reached out with his good hand and tentatively ruffled her hair. Natasha tried to swat his hand away gently. "I think I can settle for friend? Try not to get too into this debt business. I'd rather you stay alive."

"I still owe you," Natasha said and amended with a small smile, "as a friend."

The End
