"Of course, Severus."  Narcissa gave Hermione a quick hug and then she and Draco both headed for the stairs.  Hermione was trembling, staring at the man she’d once considered her best friend.  Those days felt so long ago.  That Ron would never have harmed her.  They bickered, sure, but he’d never been threatening.  This was a different, darker Ron she no longer recognized.  Draco returned a moment later with a phial and passed it to Snape, who checked that it was the right one and then went in and poured a few drops down Lucius’s throat.  He woke with a groan, and Hermione’s heart started beating again.
