Since Sierva Maria was conceived she was tagged with the phrase of an outcast. Her mother Bernada, an Indian commoner was married to the Marquis, an aristocrat and both of them shunned her out of their lives; even stating "she will be a whore."(P.42) The demons that Gabriel Garcia Marquez is trying to point out is the lack of love and duality. These two demons bring the novel to a grim ending but through it all you see that true love did try to conquer some of the demons.
Bernada and the Marquis had a bitter cold marriage and it was the hateful feeling that they had for each other that passed on to their daughter. When Bernada nursed her daughter for the first time she feared that the child would "kill her." After that Sierva's parents took no responsibility for the child and left her to the hands of Dominga De Adviento who nursed, baptized and taught Sierva three African languages along with the African culture. It was here that Sierva felt loved.
On her twelfth birthday Sierva and Dominga were at the market and a rabid dog bit Sierva, no one except for the slaves knew this until on day Abrenuncio, a physician came to the Marquis door and told him. He suddenly seemed very worried about his daughter, and as if to make up for all his neglect he tries very hard to make some sore of bond. But he neglected his own child's youth; this could never be made up for. And after many failed attempts he saw that Sierva showed no real sign of loved for this man and the Marquis now exhausted from his efforts says "The girl is not going to die" "but if she must die, it shall be of whatever God wills." (P.16) So he calls upon ever-single person he knew that could possibly have the answer to Sierva's condition. This was the two most torturous weeks that Sierva had gone through that almost killed her. But the Marquis was a determined man, except he was also a blind one too. If he truly did feel his daughters suffering he would've called everything off.
