Who does Salva come to contact with at the end of chapter 6? What is his relation to Salva?

Salva is awestruck –it is Jewiir, his uncle and the youngest brother of Salva’s father. It has been years since they last met because Uncle was fighting in the army. Uncle asks where his family is and Salva’s heart sinks because he thought his uncle would know. He tells Uncle what has been going on.
