Who is Mr. Morrison?

A random man who lives in the Logan's shed. He comes by for supper, and then excuses himself to his "little home".

No, Aiko R. Is wrong!!!!!!!! This I the real answer,...

Mr. Morrison is a friend of papa's, he used to work on a railroad and got in a fight with a white man on the job and got fired so, papa was very thoughtful and let Mr. Morrison stay with him and his family and he was there to help with work around the house and he got paid for it but Mr. Morrison said he could stay in the shed instead of in the house. So, that's where Mr. Morrison stayed for a while.
