Definitely not Sirius, if this ruse she's put on is working. It's the calm before the storm, always. Even without that, his speech patterns aren't right. She keeps her affected expression in place, hand reaching out to very gently brush his arm. She makes sure he can see it, as she always does. "Your brother's looking for you too." Quieter. "He's worried. We're all worried." Once she's inside and the door clicks shut, there's a moment. A heartbeat. Where she genuinely worries after what may happen if she can't pull him out of this.

As she steps further inside though, she casually makes her way in the direction Sirius had glanced before. It looks like she's just moving further into the flat for ease, though. Like she doesn't know what's in that direction. She's very good at this, but she doesn't turn her back to him. Not quite. "What I don't understand is you know we'd support you finding someone. You don't need to go anywhere for that. Family cares for family, after all."

Clearly it's not reason enough. Or not the right kind. She has her wand up her sleeve, something she never thought she'd have to do any more. She wonders how close to the horcrux she really is.

"Really, as though we'd abandon you just because you found someone good."
