DeSeve is a romanticized fellow. The kind of man who has everything together.
Wakefield admires his coolness and calm straight forward nature. He is a real easy going fellow. A mans man. The John Wayne type who always knows what to do. He is considered to be a man of action.
Over time we learn that he is no of these things. In trueth he is a fake. A fraud. DeSeve is nothing more than actor playing playing a role. Under pressure he is the first to turn tail and run.
