Everyone at Hogwarts knew them. Or of them, at the very least. And if you claimed not to, you were either a very poor liar, or you lived behind the moon. They commanded the attention of every room they walked into, turning heads wherever they went.  

Barty Crouch Jr., Y/N Black and Evan Rosier.

Opinions on them varied. Some liked them – loved them even (mostly Slytherins). Some hated their guts, and some were mildly terrified of them. With first- and second-years it tended to be more than just mildly. They had a reputation. One that exceeded them by far. Older students told the freshly sorted first-years to stay clear of their path, to better not get on their bad side. Not necessarily because they would harm you, not severely, at least. But if you crossed one of them, the other two were bound to make your life a living hell.

They were fiercely protective over one another – some would even call it obsessive. They embraced it without hesitation. They were obsessed with each other. And not afraid to admit it. During their fourth year, there was a rumour that they’d found a spell in the restricted area of the library. An ancient spell that tied together souls. When they caught wind of said rumour, they indulged in it – just for shits and giggles.

Only when they were thoroughly examined and checked for that spell by the Ministry itself, did they drop the act. Especially when, among the Ministry-employees that were tasked with making sure the three teens hadn’t bound their souls to each other’s, there was Bartemius Crouch Sr., Barty’s father, who had rained hell upon him after hearing about the rumour.

It had actually been a miracle that the man had made it out of the castle alive. Because both Evan and Y/N were boiling with rage as they had been forced to watch Barty get belittled and utterly humiliated by his father.

They were rarely ever seen apart. Wherever one of them was, the other two were bound to be near.

Each of them had their own personality that somehow fit together perfectly.

Barty was loud and proud. An almost constant bundle of energy with a brain that ran a thousand miles at nearly all times and rarely seemed to stop. He commanded attention with his volume, as well as with his appearance. He laughed like a damn hyena and when he talked, he rarely did it anywhere near quietly. Telling him any type of secret was therefore never the best idea. A lot of people had learned that the hard way. Not to mention that the stick-n-poke tattoos which littered his arms, hands and whole upper body, paired with his rather extraordinary choice of clothes and the green streaks in his otherwise dark brown hair, were bound to catch people’s eyes.

He was batshit insane, to put it lightly. He liked to say that his psychotic tendencies were a part of his charm, a sharp smirk adorning his face whenever he said it.

He was a bit of a pyromaniac as well. In third year, he nicked a lighter from a first-year muggle-born Gryffindor, and it had been the thing to kick off his not-so-little obsession. Wherever he was, the lighter was with him. And whenever he was bored or the ever running energy in his body was low for once, he could be found staring at the little flame in wonder. He could barely comprehend at times that muggles had created a tiny metal container that sparked a flame. It just had to be magic, in his opinion. Oh and when during classes, the topic of Fiendfyre was discussed, Barty was never seen as invested. Within the same week, he had consumed just about every book there was on the topic in the library. It was safe to say that both Evan and Y/N had checked his temperature multiple times, because he was studying. Willingly. Don’t get it twisted, he always had top grades – for whatever reason – but he never, absolutely never studied until he was forced to.

Evan was quiet and kept to himself most of the time. His social battery was on low constantly and he liked to only keep few people around him at most times. While Barty wore his heart on his sleeve most of the time, Evan was more reserved, more stoic. He had – as Dorcas liked to put it – a resting bitch face. He never denied it. It wasn’t a matter of shyness that made him quiet. He simply did not like to waste his energy on people he did not deem worth it. Optically, he was more or less the opposite of Barty. His hair was platinum blond, his skin pale, mostly void of any decorations and his clothing style rather basic, compared to the slutty (as described by Regulus) way Barty liked to dress. Everything he did was done so in a quiet, yet all the more significant, way. With purpose and silent precision that screamed louder than any words ever could.

Arguably, he was just as crazy as his boyfriend. Yet most tended to underestimate him because of his silent nature. He often got dubbed as the normal one. Everyone that had seen one of his little dissecting sessions begged to differ.

Evan had a fascination with all things dead. And with death itself. It intrigued him, in some strange way. Another one of his special interests was anatomy, which ultimately led to his little hobby of dissecting things. Mostly small animals. Frogs, rats, sometimes birds. Once Barty and Y/N had found him in the middle of the common room with a dead toad on one of the tables, its stomach sliced open as he poked and prodded at it with adorable concentration. As it turned out, said toad had belonged to a second-year Ravenclaw and was actually called Francis. Y/N had had half a mind to be mad at him, but with one bat of his pretty little eyelashes she had all but forgotten about it in less than a second.

Y/N was a combination of both of them. Her state of mind could change from one minute to the other. One second, she could be all happy and hyper, the next she could be cold as ice with a silence only her twin-brother Regulus could rival. Her mood often depended on which of her boyfriends she was around. It happened automatically. Whenever she was around Evan, she tended to be quieter as she leaned into his ever so calming presence. And whenever she was with Barty, neither of them could be stopped, true partners in crime. When they were all together – which was most of the time, admittedly – it mostly depended on the situation. She could either be getting on Evan’s last nerve with Barty or have the latter whine at both her and Evan for being boring.

Her looks weren’t exactly extraordinary. She inherited the typical Black-appearance. A pale complexion with pitch-black hair that cascaded down her shoulders in silky waves. When not in her school robes, she was often found in a sometimes questionable combination of her boyfriends’ clothes.

Barty and Evan’s little hobbies and interests went hand in hand with hers. She loved to collect things. Mostly weird and morbid things no one else did. Things like medical tools (cleaned but used – very important detail), bones, knives, rings, you name it. Whenever Evan finished another one of his little dissecting projects, he was bound to hand her some type of animal bone. Whether that be a rib from a bunny or the skull of a raven. Barty had a habit of bringing her a handful of rings every other week. She didn’t know where he got them all from. But she always loved every single one. She also kept every knife she found and one time, after summer break, she came back to Hogwarts all proud to show her boyfriends a pair of real lobotomy tools she somehow managed to get her hands on. They were afraid to ask.

They were a match made in heaven – or hell, depending on how you put it.

In fourth year, one winter night in the common room, they had all promised to stay together forever. For all eternity. Their entire lives and beyond. Y/N had ran off towards the girls’ dormitories and came back a minute later with three silver rings clutched tightly in her hand. One for each of them, to seal their promise.

She had explained what each of the rings meant. What they represented.

Barty’s ring formed the shape of a snake that wrapped itself around his finger. Partly to represent his – their – house, obviously. But also to show how agile and wild he was. That his father would never be able to tame him, that he would always be able to slither out of his father’s grip, that he would be free.

Evan’s ring held the head of a crow in its middle. To represent his intelligence, the way he appeared all mysterious to those around him. A puzzle no one could solve. No one but them. And crows symbolized death, something Y/N deemed fitting for Evan, given his fascination with the topic.

For herself, Y/N had chosen a silver band with the engraving of a simple human heart. No other intricate engravings or decorations. She chose it to embody the strength of their bond. The simplicity of it illustrating that they didn’t need anything fancy or extraordinary to show just how deep their love for each other went. That her heart beat for them. Just as theirs did for her and each other.

They held true to their promise for as long as they could. Even as the first Wizarding War progressed. They all joined the Death Eaters. Evan and Y/N under the pressure of their families, Barty to spite his father and to not be parted from his loves. They did the Dark Lord’s bidding, did anything to stay alive and in each other’s presence.

The first setbacks were the deaths of Regulus and Dorcas. While Regulus’ death left them – especially Y/N – questioning whether what they were doing was the right thing, Dorcas’ murder at the hand of the Order of the Phoenix only solidified their choice once more.

They worked flawlessly as a trio, Voldemort himself was quite pleased with them, which they viewed as a high honour. And a symbol of safety. As long as they stood on his good side, they were safe, right?

Wrong.

Because one night, Evan and Barty off on their own assignments while Y/N stayed behind in the cramped one-bedroom-apartment they shared, Barty and Y/N’s rings grew hot.

Back in fourth year, Evan had put a spell on the rings. Whenever one of them was in danger, the other two rings would heat up. The higher the temperature, the worse the danger.

And their rings downright burned against their skins. As all three of them were separated, neither Barty nor Y/N knew who of the other two was in danger. Just that at least one of them was.

Barty – already almost finished on his mission – threw the last killing curse before apparating back home, finding Y/N safe and sound. Her gaze had snapped to his, half-relieved with the knowledge that he was okay, half terrified with knowing it was Evan that was not safe. And neither of them knew where he was.

They had both hissed in pain as their rings reached a temperature that bit at both their skins, leaving a nasty burn as they instinctively pulled the metal away. The scorching heat only lasted barely more than a few seconds before the rings grew cold. Like ice.

And even though they refused to accept it, they both knew what that meant.

Evan was dead.

The crow on his ring symbolized death, his biggest fascination. And that is what he became.

Consumed by rage and grief, the two had burned down the run-down and abandoned apartment-complex, leaving only dust and ashes behind. Every memory, every picture, every single one of Evan’s possessions. They couldn’t dare to look at it. So they burned it.

They worked on auto-pilot after that. Their assigned murders of members from the Order didn’t get executed by a simple Avada Kedavra anymore. No, they wanted it to hurt. The Cruciatus Curse was a necessity, a knife almost always involved. They killed, morbidly. Brutally.

The man who had tethered them to earth, kept them from going completely off the rails, was dead. And they were going to let the entire world feel it.

Your loved ones started dying one by one, taken out by members of the Order, the people you were forced to fight side by side with and call your allies.

Dorcas died during another Death Eater attack which the Order had been made aware of and was able to interrupt, effectively saving the victims and eliminating the participating followers of Voldemort.

One time, before an Order meeting, Dumbledore had pulled both you and Sirius aside, breaking the news that Regulus had been officially declared dead after having vanished from Voldemort’s ranks weeks ago. No one knew what happened, just that there was no sign of him still being alive.

After Voldemort had found the Potters and killed them and vanishing right after, only leaving Harry behind, who he hadn’t been able to murder, Death Eaters got caught one by one, Aurors still working on overtime. When you’d heard Dumbledore, Mad-Eye and another member of the Order talk about attending Igor Karkaroff’s trial, as he apparently had names, you had known you needed to act.

So, with the help of some very useful Polyjuice potion, you had accompanied Dumbledore and Moody to the trial, where your entire world crumbled.

You were sitting next do Moody, diagonally behind Dumbledore, the cage in the middle of the courtroom rattling as Karkaroff was lifted up into view. Your eyes, however, had been focused on Bartemius Crouch Senior, Head of the Department of Magical Law Enforcement. Also known as Barty’s father. Oh, how you hated that man.

“Igor Karkaroff, you have been brought from Azkaban at your own request, to present evidence to this council. Should your testimony prove consequential, council may be prepared to order your immediate release. Until such time you remain, in the eyes of the Ministry, a convicted Death Eater. Do you accept these terms?”

Even just his voice was enough to make you want to curse him in every way possible.

“I do, sir.”

“And what do you wish to present?”

“I have names, sir. There was a Rosier. Evan Rosier.”

Your stare snapped from Crouch straight back to Karkaroff. On the outside, you forced yourself to remain calm as to not blow your cover. Internally, your pulse was spiking and you were already starting to panic.

You watched as the guy next to Crouch fumbled through a pile of papers, eventually holding one out that the former snatched right from his hands in a rather impatient and aggressive manner.

“Rosier is dead.”

That’s when you were sure that your heart stopped. Evan was dead.

“Yeah, he took a piece of me with him, if you know what I mean.” Moody’s amused and hushed tone snapped you out of your already spiralling thoughts.

Took a piece of Moody with him? Realization dawned on you, then. Alastor “Mad-Eye” Moody had killed Evan Rosier. One of the two boys you’d considered the loves of your life.

He’d killed him and absolutely no one had thought to tell you. Admittedly, that may have been smarter, because if Mad-Eye had come up to you and told you he murdered Evan, not even Dumbledore himself could have stopped you from tearing that man to shreds, in classic Evan Rosier fashion.

You took a few deep breaths, willing yourself to stay calm and get through this trial.

“I didn’t know.” came Karkaroff’s response to the news of Evan’s passing.

“If that is all the witness has to offer-“

“No, no, no, no! There was Rockwood, he was a spy.” you could tell he was getting desperate.

“Agustus Rockwood? Of the Department of Mysteries?”

“Yeah, yeah, the same. He passed information to You-Know-Who from inside the Ministry itself.”

And you could also tell that Crouch was not impressed.

“Very well. Council will deliberate. In the meantime, you will be returned to Azkaban.”

This caused Karkaroff to panic. “No! Wait, wait. Please, please I have more. What about Snape? Severus Snape?”

Dumbledore was on his feet faster than you could blink.

“The council is very much aware and given evidence on this matter. Severus Snape was indeed a Death Eater, and prior to Lord Voldemort’s downfall turned spy for us, a great personal risk-“

Dumbledore continued steadily, even as Karkaroff rattled at the cage with a wailed “That’s a lie!”

“-Today he is no more a Death Eater than I am.”

Crouch finally decided to cut in. “Silence!” he shouted, dragging the word out as he hammered his stamp repeatedly onto the table for what you were sure was dramatic effect.

“Unless the witness possesses and genuine name of consequence, this session is now concluded.”

“Oh, no, no, no, no, no.”

The way he said it was unsettling, and the silence that accompanied the calmness with which he said it showed that you weren’t the only one feeling it.

“I heard about one more.”

“What’s that?”

“A name.”

“Yes?” Crouch was getting fed up, but he was still intrigued and curious.

“I know for a fact that this person took part in the capture and by means of the Cruciatus curse, torture of the Auror Frank Longbottom and his wife.”

Karkaroff’s conviction was terrifying. Whichever name he had, he was a hundred percent sure it would be his way out of Azkaban.

“The name! Give me the wretched name!”

“Barty Crouch.” A pause, followed by a small smirk on Igor’s face. “Junior.”

As soon as the first two words had left his mouth, your head had turned into the direction where you’d spotted Barty as soon as you’d entered the courtroom, which was simultaneously the first time you saw him since you’d been dragged into opposite sides in this war. He’d hidden himself quite well, but you always had a knack for sensing his presence and finding him in a room full of other people.

He was trying to slowly walk down towards the exit without raising much suspicion, but after Karkaroff’s shouted “Junior.”, he had no other chance but to bolt.

Moody was fast with pulling out his wand, and with one flick, Barty was sent crashing into the piles and piles of parchment just below Crouch’s desk. You had to force yourself to stay seated and not decapitate Mad-Eye for not only killing one of your boyfriends, but now also daring to attack the other one right in front of you.

As they dragged Barty before his father, he hissed and shouted profanities into Karkaroff’s direction. Despite the situation, you had to admit that the absolute terror in Crouch’s face was rather satisfying.

With all the ruckus, you could barely see what was happening, but you heard Barty’s voice, loud and clear. How you’d missed it.

“Hello, father.” the words were condescending, no doubt spoken with a smirk on his lips.

“You are no son of mine.” was the last thing you heard before being forced to leave the courtroom with Dumbledore an Moody, just taking in the far-away sound of Barty’s manic scream as you left.

To you, it was still a surprise that you hadn’t attacked Mad-Eye after the whole ordeal. But you’d been forced to keep it a secret that you’d even attended the trial. So as soon as you’d been back and managed to give the unconscious guy, who's name you couldn’t even remember now, the memories of the trial so no one would get suspicious, you’d disapparated back to the small apartment you now owned and had trashed every single thing it contained out of rage and grief.

Barty was taken to Azkaban after the trial. And so, all of your dearest friends were either dead or imprisoned, never to be seen by you again.

Alright first up, I think that Barty is a switch through and through. He loves to be in control, absolutely, but the second you wanna take over, he is willing and ready for whatever. If you are more on the dominant side, he would practically beg for you to let it lose. I feel like Barty has no shame whatsoever letting you do anything and everything to him. We all know he would literally die on the spot if Evan told him to, and I feel like he would give you that same respect lol. I think that if you and Evan are dominating Barty, he could die a happy man right then and there because that is already his idea of a perfect afterlife. And let’s be real here, I think that Barty is the most down with pegging so if that is your thing, he would be all for it. Now, if you are more submissive, I feel like Barty would be the overly caring and nurturing one out of the two. I think that Barty would take the BEST care of you because you are his baby, his love and life. Whatever you ask for, it is done, no questions asked. He would quite literally worship you and his favorite way to show his dedication would be none other than burying his face between your thighs for hours. If he could, Barty would eat you out all day long, not coming up for air, food, water, or rest. This man is devoted to his loves and will lose himself in your pleasure. Barty enjoys you riding him no matter if you’re more in a dominant or submissive mood, so that he could watch your tits so close to his face. He would also LOVE making you into a pillow princess. Now this is one thing that he and Evan disagree on, Evan believes that you should have to work a little bit for your pleasure, but as said before, Barty is willing to give you everything you want and need, all you have to do is lie back and take it. I feel like Barty’s favorite form of punishment/torment is overstimulation, making you cum over and over again until you are literally pushing away from him and Evan tells him it's enough.

Now Evan is also a switch, but I can see him leaning more on the dominant side. I think that he would love to watch you and Barty, no matter who is in control. He takes pleasure in seeing not only one but both of his partners in complete ecstasy. If you are more dominant, Evan would give in, not as quickly as Barty, but wouldn’t put up too much of a fight. I think that he would rather share Barty, allowing you both dominate him (which Barty is completely on board with by the way) rather than have you in control of them both, but if that is what you prefer he will absolutely give in. he will just push Barty down a peg on the totem pole so that he feel slightly more in control. And if you are on the submissive side, Evan is a little more hard on you than Barty. Evan loves seeing you on your knees for him, like I said before, he believes that you should work a little bit for your pleasure, and this is his favorite way to put you to work. He loves threading his fingers through your hair or pulling it up for you so that he could get a better hold to fuck your throat. Evan, like Barty, would also worship you, but his preferred method is to sing your praises; “fuck baby, your mouth is so good” “you’re so tight baby, making me feel so good” “I love when you look at me like that while I fuck you/your mouth”. Now one of his favorite things to do is team up with Barty on you, he’ll play the ‘bad cop’ while Barty plays more of the ‘good cop’ and he would relish in the confusion it causes you, not knowing who to listen to but trying your best to please them both. Usually this ends in Evan giving in and finally give you what you want, usually just joining in on whatever Barty is already doing to you. Evan’s favorite form of punishment/torment is orgasm denial. He would love to build you up then pull away and hear you whine for just a moment before going back and then actually giving you what you want. If he is feeling particularly mischievous, he will watch as Barty is eating you out and when you are right on the edge, he will distract Barty by shoving his cock in Barty’s mouth or simply by pulling him away from you to shove his tongue in Barty’s mouth to get a taste of you for himself.
