Regulus is almost startled in light of how tightly Remus really is holding onto him. He supposes he shouldn't be that surprised, but it's still something that draws his breath ragged. He leans into him slightly for more support, listening to everything that's being said about and to him. He processes it and files it away, face strangely impassive as the proceedings happen. He's compartmentalized so soon as he's able to and it helps, somehow. It lets him focus on the tasks at hand instead of panicking or spiraling. Lets him lock down the part of him that wants to scream and never stop.

He doesn't argue with Remus' vehemence any more at the moment, in any case. He's none too pleased with the idea of having to quaff more potions in response to the one he's already taken, but he supposes he can manage it. It all goes so fast, really, from start to finish. Kreacher is sent home to Grimmauld Place before his disappearance is noticed. Regulus almost doesn't realize they've gotten to the safe house for a long moment. But then they're alone and he's reeling and everything is coming back in sharp relief and he takes a shuddering breath, healed hand - that will scar - clutching at Remus' arm so tightly that his knuckles are white.

He feels tired and cold and hollow and he doesn't know what to say. "I'm--" There are a few false starts with it and finally he just lets his forehead drop to Remus' shoulder. He's trying to keep his brain from running away from him but it's difficult; it's the fact he'd tried to die, the fact that Remus had thought him capable of torturing or killing his brother, the fact now Remus is so repentant. It's overwhelming and he finally lifts his head again to look at him, eyes wet but without any tears falling. He lifts his free hand to press to Remus' cheek, leaching some of the warmth from him.

"I'm tired," he finally settles on, awkwardly. "I should--try to sleep, probably."
