What I got is that lilith is a legit psychologist and she is helping they guy who is insane. Her acting as a confederate in his scheam seemed odd to me and then at the end it felt like what WE saw where all his psychotic delusions. When he busts into her room, al her ctions and statements are true and it is he that is insane. A plot twist.
Has this ben brought up do others see it this way?
I talked about it a little bit in my comments, you might find it interesting:
In a way, Stan's biggest and most dangerous con is himself. His entire sense of self-worth and indeed his identity seems to be bound up in his power over others, which is why he gravitates to the carnival in the first place ("It's like they're on the outside, and I'm on the inside") and why he never settles for what he has but instead pushes higher and higher until his whole universe collapses around him. I think it's significant in this context to return to Zeena's cards and the matter of spirituality in general – Stan always says it's for the "suckers" to believe in the cards, but there are several scenes where we as the audience are shown things that make us believe that not only do the cards work but that Stan might himself have some actual psychic powers. So to me this theme is suggesting not, as some have said, that there is no essential difference between religion, psychology, and carnival grifting, but that Stan has made a grave error – he loves the con so much and relies on it so much for his ego-satisfaction that he doesn't understand that the ethical limitations placed by carnival society on certain types of grifting are for his own benefit as much as the potential victim's. Stan is so obsessed with the power he gets from using and abusing other people's belief in things like ghosts, Tarot cards, and ESP that he doesn't even consider the possibility that they could be more than just a con. In the end it might not matter whether Lillith is a genuine psychiatrist or a fellow con-artist – either way Stan has made himself vulnerable by taking this simple fact for granted and pushing his con too far into deeply personal and spiritual areas, and whether he is the victim of Lillith taking advantage of his own psychological weakness or whether he has set his own trap by trusting too much in his rich victim's need and faith, he's destined for a long trip down nightmare alley.
