Summary
Analysis
Pi gathers extra water from rain and the solar stills in bags, and he worries constantly that the bags will break. He adds seawater to Richard Parker’s water, but even so they both barely survive. Whenever Pi catches food he always gives the tiger most of it. In his hunger Pi starts eating his food while it is still alive, and one day he notices that he is wolfing down the meat in the same manner as Richard Parker.
The self-aware adult Pi commented on his young self’s crippling fear, and now he notes the savagery he once descended to. Martel continues to blur the line between human and animal.
