Here's a breakdown of the conflict:
* Noodle is a con artist: He is initially presented as a cynical and selfish character who sees the world as a game to be played and won. He's willing to exploit others for his own gain, even if it means harming them.
* He's forced to confront his actions: The events of the story, particularly his involvement in the "Flush" scheme and his encounter with the victims of his con, start to shake Noodle's moral foundation. He begins to question his actions and the impact they have on others.
* Noodle struggles with guilt and responsibility: As he realizes the true consequences of his actions, Noodle grapples with guilt and a growing sense of responsibility. This inner conflict is amplified by the presence of his conscience, manifested as a talking, self-aware toilet named "Flush" who constantly calls him out on his misdeeds.
* He's torn between self-preservation and doing the right thing: The conflict reaches a climax when Noodle has the opportunity to expose the criminal activities of the corrupt Florida politician, "Big" Jim Sneed. Noodle must choose between protecting his own interests and facing the consequences of his actions by taking a stand against injustice.
Ultimately, Noodle's internal conflict forces him to confront his past, grapple with his guilt, and make a choice between his selfish desires and his growing sense of moral responsibility. This internal struggle fuels the plot and drives the character's arc throughout the novel.
