"Granger! Stop. I- I’ve given it some thought and I don’t think a silencing charm will serve the correct purpose. It’s not necessarily visible when I am unable to... retrieve myself from a memory. And Severus is a portrait, not like he can break the charm to inform you. Just, I would appreciate your discretion. Don’t go giggling to your friends about what happens in this room– I have to do this. It’s like all of our list questions... It's difficult for me, but I’m working on it, so it wouldn’t be helpful to have it turned into a spectacle."
