"And what then? Been like you? Forced myself into Slytherin and joined up with the Dark Lord so I could get myself killed sooner rather than later?" He shook his head, there had been no good options when he'd been young, but at least he'd managed to be happy for a while. That counted for something in his book. He gritted his teeth as Regulus seemed to enjoy the path that Sirius and his friends had gone down in the end, "It sounds like we all got what we deserved in the end, you included." He ground out, he didn't want to fight, but Regulus made it so easy to turn back to anger and frustration.
"You can do whatever you like, I always have." He waved off the suggestion that anything he said had anything to do with jealousy. "I never gave up on you," He shook his head, "All I did was live my life, that just didn't fit into the plan I was supposed to follow." It meant that he'd lost everything he'd ever taken for granted for so long, not just his parents, who were no great loss, but Regulus too. But he wouldn't have changed it either knowing what he knew now.
Sirius sighed, "I'm not interested in changing history, that doesn't mean I don't think I shouldn't go back and live it." Even knowing how it ended for him, Harry lived, that was what mattered and he'd gotten to know him for a time. That alone was worth going back for. "What kind of life exactly do you think any of us can have here? Trapped in this place, at the whims of some sort of magic that no one understands." That didn't feel any more like living than being trapped in Azkaban. "I've already spent enough time in one prison to consider tying myself permanently to another." Sure this one was more comfortable than the last, but it was the same thing in many ways.
"If it means you're not coming around throwing my past in my face, then yeah." He nodded, "I think avoiding one another is the better move."
