Two days earlier, Draco told the Notebook about Voldemort’s defeat and brought it to Defense Against the Dark Arts class, where it recognized the professor’s condition. Back in the Slytherin common room, the Notebook asked Draco to have Crabbe and Goyle hold it, and its name briefly changed to theirs.
