Lily's smile widens. Just a little. It doesn't reach her eyes. That's all she'd needed to know to be sure. "Sirius Orion Black, if you think you can get rid of me so easily than you really have forgotten a bit much, haven't you? It hasn't even been that long since you've left us." She cants her head to the side and there's something genuinely hurt there, quiet and buried in her heart and the backs of her eyes. Still, her gaze flicks once in the direction Sirius had looked.

This is not the Sirius Black she knows. "You don't look well enough to go out, anyway. You should stay home, darling. Let me in, we'll have a chat." Her voice has taken on something soothing, gentled, non-threatening. Sirius would know it's dangerous. Whoever's (as if it isn't clear already) taking control of him won't. "If nothing else I'm going to need you to explain to me why so that I have something to tell Harry. He asks for you every day. So, Sirius. Tell me what's drawn you away from him? From us?"

It's very clear she's not going to leave, in any case.

"Of course, if you convince me it's what you really want, I'll let you be. I just want you to be happy."
