It takes a moment for Regulus to come to properly. It's like waking through a fog, his body sore and aching but he barely notices that because his mind is scrambling to remember something, something important—and then he opens his eyes Remus' face swims into view and he remembers.

He remembers very suddenly and his first reaction isn't anger or that heartfelt begging to die. No, it's something instinctive, ingrained, and if Sirius is capable of looking he'll recognize exactly what it is. It's familiar when his breath catches sharply in his throat, eyes wide and wet and terrified. The way he moves too, a jerking scramble away from him (not back into the door but sideways) using his hands that causes him to nearly topple all over again.

It's the same way he'd reacted the first time their parents had hit him - betrayed by and fear of someone that's meant to love him, to protect him. His breathing is a little ragged still and he doesn't speak, just stares at him unseeingly. He doesn't even register that Remus is crying.

His gaze clears as it flicks down to the wand in Remus' hand and that kicked dog noise escapes his throat again. He can't help it. "Going to finish the job?" It's hoarse, and he can't even pretend it's something other than begging. For death or absolution, he's not sure which.
