Murugan is Rukmani’s third son. Murugan moves to a large city to work as a servant, and eventually marries a woman he meets there, Ammu. Like his older brothers, he refuses to live as his parents have and even makes major decisions without consulting them. When Rukmani and Nathan are evicted, they travel to the city in hopes that Murugan will take them in; however, they discover that he’s abandoned his wife and young child, and his whereabouts are unknown. Rukmani feels both sadness for the loss of her son and shame that his character has proved less virtuous than she hoped.
