Chapter 19: Okonkwo's seven years of exile are coming to an end. Before he returned he provided a large feast for his mother's kinsmen. He is very grateful to them for what they have done for him during his exile but regrets the fact that he could have influenced his clan more. He also hates that he spent time with such unmanly men ofr so long. At the feast, someone expresses how surprised they were that Okonkwo was so nice with the food and everything. Another praises his devotion to the kinship bond. The same person also expresses his worry for the children because christianity is winning so many over.
What is the purpose of part 2? I think the purpose of it was to tell how he was sent to exile and to tell you the things that go on while he was gone. I personally think that if Okonkwo was there when the missionaries came Nwoye probably never would have converted unless he did it without Okonkwo knowing. I don't think Okonkwo would have let such a thing happen.
