"Because it wasn't your fault, because nothing you could have done would have changed the outcome, because you were targeted because of your father, just as much as they were targeted because of you," he said. "They give up everything, but think about it, Remus. What if they felt the same guilt? It was their fault that you were turned." He cupped Remus' cheeks. "It wasn't their fault, just like their deaths were not yours. You had done nothing other than try to fight the Dark Lord. You can't blame yourself for that. In the end, you did the best thing you could possibly have done for them: survive. You want to blame someone blame him, blame me. Whatever you do, you need to remember it when you see him, because you need to be strong up here," he said, tapping Remus' temple.
Regulus shook his head. "No, this isn't about guilt, Remus. I thought I could do this. I thought we could have a few months before going our way, but I thought- I really thought you would leave me, and that... it's worse than anything I've ever felt. I don't know how we're going to do it. I have no idea, but we'll find a way, for all of it, because I can't imagine feeling like you are feeling for my own parents, and when I- when we have children, I want this. I want children that care for me as much as I care for them. I... I have no idea how we'll go about it, but I'm stubborn and I'll find a way."
He nodded. "I... I'm sorry. I probably- No, not probably, I should have told you, but I was too scared to do so,. The rest will come slowly. Maybe you don't have to know, but you should know. As you said, no more secrets. I just need some time."
He sighed. "Of course it can. It's your parents, Remus. You know how he is with you and Potter. If it comes to a crucial moment, he shouldn't have any doubts, he shouldn't question whether he can trust me, and if discovers it from Greyback- There are too many variable once Greyback figures out that we're together, and I think it will be an issue. The fact remains that Sirius has been very good at telling me that he doesn't want to know without even saying the words. I don't think he wants to know, but yes, there were too many times when we were fighting on opposite sides, and a simple lie could make him think that I was the one. It really wouldn't take long, mention a battle, say that I was the one hexing him. He'd have no way to know if it's the truth or not, not unless I tell him before." He sighed. "I know I should tell him all, but I don't want to. I don't know if we'll even be speaking after we're done."
Regulus squeezed Remus' hands. "Shh, I'm not. I'll stay away from him as much as I can. I still think that it's the wrong tactic, but learning isn't going to hurt me, so we'll do it, and I teach you that little spell with the silver knives, and a few more, mostly with fire and silver. I can fight and I can oppose him. You shouldn't worry about me. I promise that if he gets his hands on me, I'll just Disapparate and let someone else fight."
He was more than happy to kiss Remus and convince him that he meant every word he'd said tonight. Each touch was a silent promise. He would never hurt him again; he would never let Greyback hurt him again, and if that meant protecting the people Remus cared about, then so be it. "I love you," he whispered between kisses.
