Summary and Analysis: Part Two—The Pacific Ocean—Chapters 68-77
Chapter 68 describes how Pi's sleeping patterns changed (he slept only at brief stretches) and how they differed from Richard Parker's (he slept for a long time). Chapter 69 describes the times Pi thought he saw a light in the distance and set off flares to attract the ship's attention.
If the previous chapters had shown how animalistic Pi had become, these chapters show how great a distance there still is. Pi cannot sleep much because of his anxiety, and it may be false hope that makes him shoot off the flares. Richard Parker just accepts.
