Okonkwo is finally sleeping after Ikemefuna's death. He is awoken one morning by one of his wives, Ekwefi. He is at first angered that she would wake him up, but then heres what she says.
Ezinma is sick and lying in the center of her mother's hut. Okonkwo leaves to go and create a medicine, while Ekwefi worries and tends to Enzinma.
The Ogbanje in Ezinma
Where is it?!
Chill out. You literally hired me to do this.
Where they bury children.
In the past, Ekwefi had nine children who all died as infants. She was told by a doctor that she was cursed with an ogbanje, a spirit that took over and killed the child and then rebirthed inside the next to cause her grief. Ekwefi becomes hopeless and bitter.
Ezinma was the first child to live older than a couple years, and she was determined to live. Once Ezinma lived to five and six years, Ekwefi began to truly care for her.
Ezinma is still a ogbanje, and so in order to stop it Okonkwo sees a doctor who specializes in them. The doctor asks Ezinma to take him to its iyi-uwa, the ogbanje's physical link to the Earth.
Ezinma identifies where the iyi-uwa is under an orange tree. Okonkwo and the doctor dig it up with hoes throughout the day. Ezinma is now free and will not die. In the present, however, Ekwefi is still very worried about her daughter whenever she gets sick.
