The author describes Pi showing him old family photos. There are pictures of Pi’s wedding and his days growing up in Canada, but almost nothing from India. There are only four random photos, one containing the mysterious Richard Parker. None of the pictures have Pi’s mother in them, and Pi says that he has started forgetting what his mother looks like.
Pi’s ordeal has also involved the loss of all his belongings from India. This lack of proof for his backstory (especially in light of his later actions) calls Pi’s reliability into question – all his stories of childhood might also be “spiced up.”
