When does Nhamo return to the science station?

Nhamo goes back to the science station after living with her uncle. When she first arrives at the station, Nhamo wants to stay, but she is advised by the scientists to attend school. The scientists contact Nhamo's uncle Industry, who at first believes that Nhamo is an imposter who wants his wealth. Once Nhamo is able to convince Industry about her lineage, he allows Nhamo to stay with him and attend school with his children.
Although her new life is better than her life back at the home village, she still feels distant from her family. As a result, the scientists begin to fulfill the supportive aspects of family that Nhamo has lacked throughout her life. Not only do they nurse her back to health, they also teach her to read and write. Also, the head scientist saves the gold nuggets that Nhamo got from Ambuya in case Nhamo needs them in the future.
