One important quote in Chapter One explains the relationship between Mark and Byron... the loyalty, and the friendship.
“I had been friends with Mark long before he came to live with us. He had lived down the street and it seemed to me that we had always been together. We had never had a fight. We had never even had an argument. In looks, we were complete opposites…He was my best friend and we were like brothers” (13).
That Was Then, This is Now
