Identify the minor characters and choose a revealing line of dialogue for each. What do we learn about Robert’s character based on these characters?

The most important minor characters in The Wars by Timothy Findley are Rodwell, Rowena, and Lady Juliet d'Orsey. These three minor characters in particular are highly influential to the main character Ross.
Through Rowena and her unexpected death, we learn that Robert has a strong conscious and desire to seek retribution for the guilt that he feels surrounded her death. Robert is also inspired by his sister's love of animals and because of this, he begins to save animals. Rowena is disabled and though she is an adult, she behaves much like a child. This is seen through her asking her brother, "Will you stay with me forever?"
Rodwell, who also loves animals, causes Robert to realize his selfless nature. Robert realizes that all living things are precious. His time with Rodwell is what pushes Robert to become a war hero. A revealing line from Rodwell is in the letter he writes to his daughter before he kills himself. He says,

"I am alive in everything I touch. Touch these pages and you have me in your fingertips. We survive in one another. Everything lives forever. Believe it. Nothing dies. I am your father always.”

Juliet d'Orsey gives Robert the strength and hope that he needs to become a war hero. She remains his friend after he is disfigured from the war. A notable quote from Juliet is,

"Someone once said to Clive: do you think we will ever be forgiven for what we've done? They meant their generation and the war and what the war had done to civilization. Clive said something I've never forgotten. He said: I doubt we'll ever be forgiven. All I hope is—they'll remember we were human beings."

All of these notable quotations tie together the idea of how people are never truly gone, but they go on forever through memories and through other people.
