Well, would you look at that. Their discussion was moving moving to the darker side now. Beezus' insides practically knotted when the man said he will be teaching them spell that would determine if a person died in a particular area or not. This was making her, and she's sure that she wasn't alone, very uncomfortable. But supposedly this all had to fall in and provide them with a productive lesson, yeah? So she can't really complain.

Homenum Revelio. The Prefect raised her hand and offered an answer, "Homenum Revelio, or the Human-Presence-Revealing Spell from the name itself reveals human presence within a surrounding area." Gulp. "As is, it detects a person even when he is wearing an invisibility cloak."

.....Geez.

As she talked, Beezus strained her eyes on the board....particularly on the list of those deaths with unknown locations....and then her eyebrows forked. "Oh, and....excuse me sir..." Corrections? Was he still accepting them? She had one right now. "I don't think the Fat Friar died here at Hogwarts....he was executed by churchmen and he returned to the school as a ghost afterwards." Er, yeah.
