Summary
Analysis
The author returns again. On one of his visits he meets Pi’s two children, Nikhil and Usha. Again the author had no idea that Pi had children until he suddenly encounters them. Usha, who is four, is holding an orange cat in her arms and laughing. The author declares that Pi’s story has “a happy ending.”
Pi’s orange cat is a clear reference to Richard Parker. Martel has shown Pi’s happy childhood and happy adulthood, but now he will show the suffering that lies in between.
