What role did Hemadpant's son and his unique writing habits play in the events described in Chapter 53?

Chapter 53 highlights the significant role of Hemadpant's frugality and his son, Gajanan. Hemadpant was so frugal that he would write chapters on scraps of paper to avoid waste, feeling compassion for even "poor, lifeless scraps." After Hemadpant's sudden passing, his son, Shri Gajanan, undertook a great effort to research his father's vast records. As chapter 53 recounts, Gajanan provided the necessary materials to the new author. It was during this process that he and others, like Babasaheb Tarkhad, discovered that the final chapter was also written on these scraps but that the promised summary could not be found within them.
