We all use math every day ... Inspired by actual cases and experiences, Numb3rs depicts the confluence of police work and mathematics in solving crime. An FBI agent recruits his mathematical genius brother to help solve a wide range of challenging crimes in Los Angeles from a very different perspective.
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 than he. 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. After realizing that he would never be better than a single A player, Don quit the Rangers and signed up for the FBI test the next day.
In the FBI Academy, he dated fellow agent Terry Lake. As he later told his father, his favorite date ever was when he had pizza in a laundromat with her. Terry does not share that opinion. After graduating from the Academy, Don worked in Fugitive Recovery with Billy Cooper (episode "Man Hunt") and former Navy SEAL Petey Fox ("friendly Fire") and was very good at it. He taught at the FBI Academy for a time after Fugitive Recovery to help him come back to civilization ("Longshot"). After that, he worked in the field office in Albuquerque, New Mexico, and dated Kim Hall (Sarah Wayne Callies), and nearly married her. Don gave up his position as Special Agent in Charge of the Albuquerque FBI office to move back to L.A. when his mother became ill with cancer, from which she eventually died.
Don is a principled character and very devoted to his job, leaving him not much time for a social life. According to actor Rob Morrow, Don has a tendency to sacrifice, even at the expense of what he wants from life. He enjoys the occasional game of baseball and is also often seen watching hockey, which he played in his youth. He went to college on a baseball scholarship. Don thought baseball was his first love, though his father Alan Eppes reminded him that a toy gun and playing a cop as a child was actually his first love, and comforted him in noticing that the FBI needs utility players. Charlie said that he was a "born cop." Don's giving up on the game is an emotional subject for him.
He and Charlie have had their differences over the years, and Don finds it hard to go to Charlie for help to do his job. In fact, in "One Hour" Don states that he does not like living in the shadow of his genius brother, though he respects him and his abilities very much and they have become closer. Sometimes, he feels that Charlie isn't doing all the great things he could be doing because he is working with the FBI. Still, he does often question his brother only to have his faith in Charlie's abilities restored. In "Burn Rate", their father says, "But have you ever known your brother to let his emotions trump his math?" Just because Don gets emotional, he thought this was the case with Charlie and even stated his brother was backing one of his own — a genius. In "Trust Metric", Charlie says that he has a giant ego.
He is a harsh taskmaster, likes being the boss, and is not very forgiving. One of his former tactical trainees from Quantico, Liz Warner (Aya Sumika), has proclaimed to this and, after Colby confided in her that he made a mistake, she told him that the very fact that he still remains on Don's team means something. She also said that Don never spoke of his personal life while at the FBI Academy and was at the time fresh from the field in hunting fugitives (with friend Agent Cooper). Liz knows he has mellowed with age and he can hold a commitment with a woman for longer periods of time.
He believes that the death penalty is a form of revenge.
Don has an ability to understand how criminals think, which causes him to suppress his thoughts in an effort to cope with the horrors that he sees on his job
