What are the final words the fictitious author uses to end part one of the novel? And what can the reader infer from this?

At each number he softly presses the tip of her nose with his index finger. She finds this terribly funny. She giggles and buries her face in the crook of his neck. This story has a happy ending. ch 36

The final line of Part 1 is also significant: “This story has a happy ending.” It is a powerful sentence, because the reader has not yet learned of any of Pi’s suffering; the need for such an ending is not as yet clear. Ironically, this declaration of hope and optimism spells doom, foreshadowing the devastating trials and tribulations Pi must soon encounter.
