Biography
Shortly after the birth of their son Peter, Richard and Mary Parker hit a very rough spot in their relationship, up to and including a brief separation. Around this time, Richard, having traveled to a conference in Texas, ended up having a brief affair with a woman named Delilah Carlyle– an affair which ended up with them conceiving a child. While Richard and Mary ended up reconciling (with Richard never mentioning his lapse in marital fidelity), Carlyle eventually gave birth to their child, entrusting her sister Cassandra with raising the infant Teresa shortly thereafter.
