Turning Point

When reading a story about someone's life and their journey to discover him/herself (which seems to be a common theme in a lot of fiction novels), I try to think about at what point the character turns around, reaches a climax, or changes perspectives. In The Crying of Lot 49, I felt that there was no specific point of climax for her character. The insane situation with her psychiatrist could be argued as the climax, the conversation in the bar with the man that called Oedipa "Arnold" at the end could also be argued as the climax. But, does the climax even exist in this novel? Or is the climax purposefully left out and shadowed at the end of the story during the auction? It's almost like Pynchon is setting us up for a Crying of Lot 49 Episode II.
