"Bold assumption. That I'd let you leave." Because Sirius knew he shouldn't. There wasn't really any protocol in place for his brother coming back from the dead, but it meant that Grimmauld Place had been compromised. He would have to warn everyone and he had no idea where it would leave him. Leave them.

But for now, he had Regulus right here, consequences could wait. Slowly it became more real. His brother was here and not just a memory to haunt him. Not another manifestation of guilt. "Your room is just as dorky as you left it. You really want a reminder of that?"
