Hazel was surprised at such a dark beginning to class. In her opinion, there was no better way to say, "Warning! You might get killed in this class!". So, what was this about the undead? Doesn't that pretty much just mean the opposite of dead, so alive? Because "un" means not and "dead" means... well, dead. She guessed that the intention was different, though. Like zombies? And inferi? But inferi were just dead puppets pretty much and they weren't alive. But then again, were zombies alive? They're not dead, but they're not alive, so they're... UNDEAD! She raised her hand. "Professor, isn't undead when you're not alive but you're not dead, kind of like zombies?" Maybe?
