So in Focus, Nicky leaves Jess in the car right after the big betting scene in New Orleans. I don't see why he did that. He wasn't being chased by cops or anyone. He wasn't in danger that he did it to save her life. Everything was going fine and he just left her, saying "You did great". Why did Nicky leave Jess in the car right after the betting in New Orleans?
