Dickens also explores the theme of family through Belle's character. When Scrooge sees her with her children he wonders what it would have been like to have children who "might have called him father". This causes his sight to grow "very dim indeed", suggesting that he has started to cry. This is a significant display of emotion as it highlights how deeply Scrooge is affected by regret. It could be said that this directly contributes to Scrooge's transformation as these powerful emotions illustrate the error of his ways.
