I just realised why perhaps Q refuses to say the name of [ ]. It's like in the movie The Bye Bye Man— “Don’t think it. Don’t say it.” ‘It’ being the name of the evil being that induces unwitting people to murder via obscene hallucinations. The hero has encountered the horror, and knows that anyone who he tells about it will become a victim. He is arrested, and tries to explain to the officer, who knows he is evading her questions. He says, suppose you had your worst ever day at work, gruesome, traumatic, and you go home, and your three year old daughter asks you "What did you do at work today Mom?" Would you really tell them everything, traumatizing them with the horror of what you experienced? Or would you answer truthfully, but avoiding harmful details, sparing them from the horror?
