~ Batman: Knightfall

So, Jean-Paul is schizophrenic because of the abuse he went through, the hypnosis from a very young age fucked up his perception on what is real and what isn't. What is interesting is that his visions (not sure this is the correct term for schizophrenia) are a reflection of his feelings. Here, Saint Dumas represents Jean-Paul's desire to make Bruce proud, to do a good job as Batman like Bruce would.
