Who is Reginald Nwankwo from Girls at War, and Other Stories and what is their importance?

Reginald Nwankwo is a high-ranking Nigerian official who, at the beginning of Girls at War, is intercepting some food aid at an air strip to deliver to his family. He feels bad about taking food intended for war refugees, but his family must eat. As he is being driven away from the strip, Reginald notices Gladys, a woman he has crossed paths with in the past, standing by the side of the road and picks her up. Reginald offers to drive her the rest of her way, but he recommends they stop at his residence first. At one point they hear a plane fly over and worry that it is a bomber. It is not, but Gladys and Reginald huddle in his shelter and make love.
