He survived

Sirius is honestly extremely confused. It's the morning after Regulus showed up at their flat with a broken arm and covered in blood, and all Regulus said was something about a Crux-a-Hux. Sirius wants to know why their brother randomly showed up at their flat, and why he was covered in blood. Probably has something to do with Walburga and Orion. Sirius is going to kill them once this war is over. Yes, Sirius is still mad at Regulus for becoming a death eater, but he is still Sirius' little brother. Maybe it's because Sirius is Regulus' older brother, but he still feels the need to protect Regulus and take care of him.

Sirius turns around in his bed to face Remus. Fuck, he looks adorable when sleeping. Sirius brushed some hair out of Remus's eyes so they could see Remus's face better and stared at his face. Remus looks so peaceful. Sirius would kill everyone just to make sure Remus could stay this peaceful. They would end this war just to make sure Remus could stay happy and peaceful. You know what? Maybe that's not such a bad idea. Sirius gets snapped out of their thoughts because Remus started to stir awake. Sirius smiled at Remus once he opened his eyes.

Remus smiled back and inched his way closer to Sirius. Once he got there, he laid his head on Sirius' shoulder and said with a smirk. "Were you watching me sleep?"

Sirius blushed, embarrassed from being caught but said. "I-uhm. Maybe" Remus laughed which made Sirius very happy. They loved hearing Remus laugh; it was such a beautiful sound. Sirius smiled and looked down at Remus, and Remus looked up at him, a smirk on his face. Sirius leaned down and kissed the top of Remus's head which made Remus lean up and kiss Sirius's nose. This went on for a couple of minutes. One person kissed one spot on the others face and the other kissed another spot on the others face. It ended when they heard a bang come from the living room.

Sirius got out of bed and ran into the living room with Remus following behind slower because of his bad leg. Regulus was trying to pick up some books that had fallen over. He looked scared, almost as if he was going to get hurt or yelled at because some books fell. Oh right, their parents. Walburga and Orion would always hurt them for making noise, or things falling to the floor no matter what it was. Regulus was trying to pick up the many books that fell but couldn't get a grip on them. Sirius walked over to Regulus and kneeled down by him. "Reg, Reg calm down its okay. It was just books; did you get hurt?"

Regulus looked up at Sirius with a very surprised expression. "I- what?"

Sirius grabbed the books on the floor and handed them to Remus then turned back to Regulus. "Are you okay? Did you get hurt from the books falling?" Sirius repeated. He fucking hates Walburga and Orion, why were they the shitty parents that they were?

Regulus shook his head and said. "No-no I am fine"

Sirius nodded and stood up. "Are you hungry? We have toast" Regulus nodded so Sirius walked into the kitchen to make the toast. They made it plain because they couldn't remember how Regulus liked his toast. See, that's not good. They should know how Regulus likes his toast. Sirius turned around to walk out of the kitchen with a plate that has Regulus' toast on it but jumped when they saw Remus standing there, admiring Sirius. Sirius laughed and walked over to Remus, giving him a quick kiss on his lips then walked out to the living room. "Sorry Reg I-I uhm, don't know how you liked your toast, so it just has butter on it, but I- we have jam if you'd like" Sirius set down the plate on the coffee table, and gave a small smile to Regulus.

Regulus looked up at Sirius with that same look of confusion and surprise as before. "No, no it's perfect"

Sirius's eyes widened in surprise. They didn't think they had gotten Regulus's toast correct. One point for Sirius. "Oh, oh yeah-yeah perfect. Uhm, we do still have to talk about what happened you know"

Regulus looked at the toast and began to eat. He nodded. Once he finished chewing, he said. "What do you want to know about it?"

Sirius's eyes widened in surprise again. They didn't expect Regulus to be so open to talking all of a sudden. They sat down by Regulus and said. "Well, I want to know what in hell a Crux-a-Hux is"

Regulus nodded and sighed then looked at Sirius and said. "It's called a Horcrux. Voldemort split his soul into seven different pieces and put one part of his soul into this locket. I found the locket, and I'm pretty sure I'm the only other person besides Voldemort that knows these Horcruxes are a thing" Regulus bit his lip. It was obvious he was anxious. Does Sirius make him feel that way? They hope not.

Sirius's eyes were wide again and their jaw was open. That probably didn't help with Regulus's anxiety. "I-he-how did you figure this out?"

Regulus stopped biting his lip and said. "Well, he's very arrogant and always talks about stuff like that vaguely, he just thinks no one is smart enough to figure it out. And as much as I know, no one else has"

Sirius was so proud right now. They forgot about all the bumpy parts in Regulus and Sirius's relationship and was just so proud of their little brother. Regulus is the smartest person Sirius knows, and that's a fact. Sirius smiled at Regulus and said. "Holy Godric Reggie, you are so fucking smart!" Sirius laughed and could tell that Regulus was fighting a smile. That made Sirius proud of themselves. "Okay wait, that doesn't explain why you showed up here hurt" Sirius said once he had stopped laughing and looking at Regulus very proudly, but now they looked curious.

Regulus nodded and sighed. "Well, the Horcruxes are very hard to destroy, practically invincible. One of the ways they can be destroyed is house elf powers because house elves hold greater magic. I-I had asked Kreacher to come with me to help me destroy the locket. I thought I was going to die so I told him to hide the locket and not let anyone find it. Since Kreacher is a house elf he had to obey his master's orders. But... Then I survived and I needed help, and you were the closest"

Sirius was extremely surprised. Did their little brother want to die? How did Regulus know all this? He's a smart little shit that's how. "How did you know where I lived?"

At this Regulus froze for a moment and then grabbed his other piece of toast and ate it. Once he was done chewing, he said. "I found out where you lived a couple months ago. And I remembered so I came here"

"Regulus, I moved in here a couple months ago"
"I know" Regulus said and grabbed the plate of toast that was now empty and brought it into the kitchen
Sirius got up and followed him. "You stalked me?" Sirius had no problem with Regulus coming- Actually no that's a lie; he's a death eater he's on the wrong side and he stalked Sirius to figure out where they lived.

Regulus put the dish in the sink and turned around to face Sirius. His expression was cold, just like it had been to Sirius since Sirius ran away. "I didn't stalk you, I just figured out where you lived"

"And how did you figure that out? Hm?"

"Why does it matter?"

"Because it's fucking stalking!" Sirius was starting to get angry; they hadn't been this angry since a death eater threatened Remus on Sirius's last mission.

Regulus rolled his eyes. "It's not stalking"

Sirius scoffed. "Then why is it?"

"I hunted down your address"

Sirius's eyebrows furrowed in a mix of confusion and anger. "Thats literally just another word for stalking!"

"Okay fine whatever just stop fucking yelling" Regulus waved his hand in the air and walked back into the living room.

Sirius stood there in shock and anger. That little shit. Sirius stormed into the living room. "Okay fine, we're talking about everything right now"

Regulus looked up at him from the couch with that same cold expression. "Who are you to decide that?"

"Well, you stalked me, so I say we talk" Sirius crossed their arms and arched their eyebrows waiting for Regulus to talk.

Regulus rolled his eyes. "Fine, what do you want to talk about?"

Sirius sat down by him. "Well for one, what made you became a death eater?"

Regulus visibly tensed and moved slightly away from Sirius. "Well, at first I wanted to be a death eater, but then Voldemort had used Kreacher for an experiment. I later found out he used Kreacher to test out one of the Horcruxes. I didn't like that, so I decided I'd try and... Fix my mistakes I guess"

Sirius nodded. They had no idea why Regulus was telling them this with only slight hesitation, but Sirius decided to take advantage of this. "So, does this mean you aren't on Voldemort's side? Are you joining The Order?" Regulus looked down and shook his head. "Then you are still on Voldemort's side?" Regulus shook his head again. "Then what side are you on?"

Regulus looked up. "I'm on my own side"

Sirius's brows furrowed. "How? You-you can't just make your own side"

Regulus scoffed. "Watch me"

Sirius smiled, again they were proud of their little brother. "No Seriously, how?"

Regulus looked at Sirius with a stubborn look on his face. "You can find that out later. Once-once we are on good terms again"

Sirius nodded but then their brows furrowed in confusion again. "Are we not?"

"Sirius, we talked about two things"

"I know" Sirius smiled and Regulus rolled his eyes, but Sirius could see the humor behind it. Regulus and Sirius sat in comfortable silence for a few minutes. Sirius thinks this is going well but they still have a question. "Hey Reggie?" Regulus nodded. "I was wondering, you said you thought you were going to die, so why did you still do it?"

Regulus looked down into his lap and started to fidget with his hands. "I-I guess I thought if I died for this, I died for something... Something good, like I died for a reason. And I thought if I were to die..." He took a shaky breath then continued. "I thought if I were to die, who would care? I mean, me and you aren't on good terms, our parents are-well they're our parents. But then I remembered Pandora. And I remembered Barty and Evan, and Dorcas. I couldn't leave them"

Sirius looked at their brother in shock, and sympathy, they know that Regulus hates it when people sympathize for him, so Sirius tried not to show his sympathy, but it was there. "We could be on good terms" Regulus looked up at Sirius and his eyes were glassed over in tears. Sirius's face softened. "Oh Reggie, come here" Sirius inched over to Regulus and let Regulus fall into his arms. Sirius gently rubbed Regulus's back and let him quietly sob into their shoulder. Sirius laid their head on top of Regulus's since Regulus's head was on Sirius's shoulder, it was easy. A couple of minutes later Regulus started to calm down again, his sobs starting to die down. Regulus looked up at Sirius once Sirius lifted his head off Regulus's. They looked down at Regulus and smiled. "For the record, even though we aren't on good terms yet, I would've cared"

Regulus sniffled and nodded. "I know"

Remus walked in. "As much as I hate to break up the brotherly bonding, James, Peter and Lily are coming over. Marlene apparently told them Regulus was here, so they are coming here on behalf of Dumbledore"

Regulus sighed and moved off of Sirius. Sirius was happy to help their brother. "Of course, because they still think I'm a death eater"

Remus's eyes widened. "You're joining The Order?"

Regulus shook his head. "No, but I'm also not on Voldemort's side"

Remus's face turned into one of confusion. "Then whose-"

Regulus interrupted Remus. "My own"

Remus wasn't able to say anything because the front door opened. "Oh yeah, please come in" Remus said as James ran over to Sirius. Sirius and James hugged then James went over to wrap his arm around Lily's waist. James and Lily are engaged now, but Sirius has some suspicion it might not work out.

Lily laughed at Remus's reaction and rested her head on James's shoulder. "Thanks for the invitation to come in Rem"

Remus rolled his eyes but there was definitely humor behind it. "Oh yeah, no your welcome"

James looked at Regulus with suspicion and Regulus glared back which caused James to look at Sirius. "I'm so confused"

"Don't be Prongsie" Sirius said with a smile.

"How am I supposed to not be?"

"Good point. I'll explain later, promise"

James nodded and Peter was staring at Regulus who looked as if he could murder Peter any second. Sirius doesn't know why but they feel like Regulus and Peter know more about each other then just being schoolmates. Peter looked at Sirius with a terrified expression on his face. "Sirius your brother is scaring me"

Sirius looked at Regulus who was still murdering Peter with his eyes. He then looked at Peter. "Yeah, he does that to people" Peter looked back at Regulus and walked closer to James. Sirius raised their eyebrows. Was there a reason Peter was scared of Regulus other than the fact Regulus was planning how to murder him in his head? Regulus doesn't do stuff like that if the person did nobody, so it's a possibility.
