Despite her attitude problem, Cain saw a lot of potential and goodness in Mary and took her under his wing. She has since served in his organization as his own personal assistant.

Personality
When they first met, Mary was a pretty outspoken, angsty and came across as a typical hormone driven teen. However, Cain saw more than this, upon first meeting her as she braved Deathclaw infested tunnels over an item of sentiment and stepped in to save his life. As a result, they have stuck together for many years, however, the many years have taken their toll on Mary, she has become far less confrontational and is somewhat depressed and reclusive.
