The character 'Red' in Jojo's Story

Red is a quiet boy who Jojo, the ten year old main role in the story, meets in the children's house and tries to talk to him as per Dr.Nicky's words. Nobody knows the real name of Red and everyone in the house calls him with that name as he wears a red t-shirt. He is so quiet and never talks to anyone. He, like all the remaining children in that house, is a victim of war, and seems afraid of the things happening around. Jojo is the only person to have Red utter only once 'We have goats at my home'. Red never speaks before and after that; and leaves that house one day and never returns. Jojo hears people saying that Red is killed by a landmine after leaving the house.
