Character A: Mother of the child. Looking for her missing husband. Has a strong, loving bond with her son. Late 20s
Character B: The child. His father went missing and it's unclear if he was taken or left willingly. He is 9/10 years old.
Character C: Another man A has asked to help locate her missing husband. He is a bit standoffish and cold but cares deeply about her and helps when he can. He is in his late 20s. They have known each other for a while but he hasn't met her kid yet.
Takes place in a post-nuclear apocalypse in western America.
I need C and B to bond but I'm unsure how. Their first meeting takes place in a place similar to a war camp. C retrieves food and water for the mother and her son.
C isn't one to joke around or act childish and has never been around kids.
