"You're a really good actress..." I say doubtfully.
This doesn't make any sense! It would be easier to assume she has been hit with some kind of memory charm, but I was able to talk to Hermione a few days after Edgecombe sneaked, and she assured me there'd been absolutely no memory charm in the parchment we all signed. Which was reassuring, because I know from my dad's work that memory charms are not something you mess around with.
So either Edgecombe's memory is going because of the stress, or someone else Obliviated her. Or, of course, she's faking, which is what I want to believe.
"Your name is Marietta Edgecombe," I say, still too defensive to take the aggressive note out of my voice. "Does that help?"
