Don Eppes
Donald "Don" Eppes is a fictional character and one of the protagonists of the CBS crime drama Numb3rs. He is portrayed by Rob Morrow.
Don is an FBI Special Agent who runs the FBI Violent Crimes Squad in Los Angeles. Don recruits his mathematical genius brother, Charlie Eppes, to help him and the Bureau solve some of their most difficult cases. Don makes great sacrifices in his personal life in order to devote himself to his career, which to him is more of a way of life than a mere job. More important to him than his work is his family, especially Charlie, even though he doesn't understand his brother's way of looking at the world.
Backstory
Don is the older son of Alan Eppes and Margaret Mann-Eppes. He was raised in a secular Jewish family. During the Vietnam War, his parents would take him to sit-ins, and he twice watched his father be arrested (as mentioned in the episode "Protest"). When Don became too attached to his toy gun, his parents put him in Little League, hoping Don would forget his love for guns. Don graduated high school on the same day as his younger brother Charlie, who is five years younger ("Soft Target"). He went to college on a baseball scholarship and then played Single-A with the Stockton Rangers (a fictional team) as a utility player. Charlie used to predict the number of walks he would get just from his stance at the plate. Despite the attraction, Don never took steroids, although his backup player did. That player made the major leagues and Don has since wondered if he should have taken steroids to help improve his game. The day after realizing that he would never be better than a single A player, Don quit the Rangers and signed up for the FBI entrance exam ("Identity Crisis").
