There is no reason to give the hypnosis books to anyone except maybe returning the one you "borrowed" from the detective. Read them until you get the message that they don't do any good anymore and then sell them.Damn it, it won't work and what i mean by it won't work?
After using debug to get the book i tried to give the book to an NPC who i already gave Hypnosis Tutorial, the item won't appear above Hypnosis Tutorial like how it appears in my own Inventory above Hypnosis Tutorial.
By the way, anyone know if the event where your students talk about going to a nightclub happen only once after you done it and every now and than they talk about it is just a talk and nothing else or its incomplete?
The nightclub path is incomplete at the moment.
