The Pea and Mig connect over the fact that they’re both missing their mothers. Their loss, in other words, binds them together. This makes things difficult for Roscuro; his success rested on the girls seeing each other as enemies. During the stalemate, it creates tension as the narrator describes the candles burning out one by one. When the last candle goes out, the novel implies, all hope will go out as well. But fortunately, a mouse (presumably Despereaux) will appear to make things right.
