Philip describes being attacked by gangs at a young age while collecting milk across the city. One day he fought back, and beat one of the bullies to death. As a teenager, Philip dated a young Russian woman named Irina, who shared his dream of joining the KGB. When Philip is accepted into the Illegals Program, Irina breaks up with him and tells him that she's met someone else. Later, Irina also joins the KGB as an undercover agent in Europe. Philip trains for several years before meeting "Elizabeth Jennings," another member of the Illegals Program, who is assigned to be his wife in America. They move to Virginia in 1965 and have their first child, Paige, in 1967.
