The sequence that has Passepartout feeling incredibly guilty occurs over chapters 34 and 35. Chapter 34 begins with Fogg already in prison, and the repercussions of the situation are quite daunting. The fourth paragraph of chapter 34 has Passepartout realizing that he is the cause of Fogg's misfortune. Passepartout thinks this because he believes that the entire situation could have been avoided had he only told Fogg about Fix. Passepartout realizes that had he told Fogg about Fix, Fogg could have provided evidence that showed his innocence.
Passepartout's guilt is so severe that readers are told that he cried until he was blind. The final sentence of the paragraph even tells readers that Passepartout is even considering killing himself:
Passepartout wept till he was blind, and felt like blowing his brains out.
By the end of the chapter, Fogg is free; however, Passepartout's guilt carries over into chapter 35. He is "tortured by remorse," and readers are once again told that Passepartout believes everything could have been avoided had he only told Fogg about Fix. Passepartout even goes so far as to try and apologize to Fogg, but Fogg refuses to hear it. Fogg flatly states that he doesn't blame anyone. This statement does nothing to alleviate Passepartout's guilty feelings, and he sulks away to do the errand that Fogg wants done. Passepartout eventually gets over his guilt when he sees Fogg and Aouda lovingly holding hands.
