[That sudden anger is something he's not used to from Remus--that's not his style, sharp and angry and short in a way that Remus never is. It catches Sirius off-guard at first, leaves him staring numbly at Remus--and perhaps it should have penetrated the thickness of his anger and fear and worry, and perhaps it still will--

But that last bit is the bit that sticks in him, twists, deep--and perhaps it, too, will end up changing his mind, but for now Sirius has only one reaction--so when Remus shoves away from him Sirius snaps forward like a snake, striking--grabs Remus by the shirtfront and pulls him in close with something near a snarl, every line of his body taut and angry-- there's the fear for James in there, yeah, such fear, he can't even put words to it--but he hates what he's just heard, he hates it, Remus should have known better than to say that shit to him (or perhaps he knew exactly what he was doing, who can say)--]

Shut up. Shut up, you don't know what the fuck you're talking about-- none of you do, none of you-- I'm nothing like my fucking family.
