Sirius leaned into Remus' touch, drinking in every second of it. It was rare that Remus initiated, and Sirius breathed it in like air.
"We're okay actually. Shockingly. Me and Reg. We've talked a few times now, and he only hexes me when I call him Reggie so I think that's real progress." He almost didn't continue, but they were in a sharing mood and he knew Moony would understand.
"I think they hurt him. Not the way they hurt me, but, still. I always thought I was protecting him. By drawing their attention. By staying away. But I didn't. I just left him there. I thought he was safe there, and he wasn't, and I left him behind." It didn't matter that Regulus almost certainly wouldn't have gone with him that night. It didn't matter that he would not have survived going back. "I left him there. And they hurt him. And then they killed him. And I still don't even know why."
