Severus doesn't quite choke on his food, but it's clear he wasn't expecting that on the heels of being faintly amused at her shiv mime, there.

It's not the smoothest recovery in the world but at least it's a recovery as he finishes chewing and sets his fork down, fingertips against the metal still. "For her it's been months."

Darcy knows that, he knows she knows. It's not like they were married, hell, they were barely properly dating, and Severus feels like he'll be being invasive if he does more than he's doing now. "She's-- we're." He stops short, because it occurs to him that oh, hey, Darcy knows they are (they were?) dating.

Okay.

"Claire's a private person."
