Hester Shaw’s facial scar symbolizes how sometimes a person can look like a “monster” (a word Hester uses to describe herself) on the surface, but actually be kinder and braver than people who look more conventionally beautiful. The scar also symbolizes the dark side of Thaddeus Valentine, who looks like a dashing hero on the surface, but who gave Hester that scar and who is willing to resort to murder to get what he wants. Hester lost one of her eyes when she got the scar, but in spite of that, she is often better than Tom at seeing people’s true nature, since Tom continues to believe in Valentine’s goodness even after Valentine attempts to murder him. The trauma of her parents’ murder is so central to Hester that it’s visible on her face, and this helps explain why she is so eager to exact revenge on Valentine. By spending time with the scarred Hester, Tom realizes that superficial beauty doesn’t count for much and that true friendship and love are more important than outward appearance.

I’m sorry.”

“But we’re alive, and together, and we’re going to be all right.”
