The Fifth Man (Numbers)

Dr. Charlie Eppes (David Krumholtz) moves into a new office and receives some inspiration for his cognitive emergence theory. Some time later, FBI Special Agent Nikki Betancourt (Sophina Brown) visits the new office. She reminds Charlie that her boss and Charlie's brother, FBI Special Agent Don Eppes (Rob Morrow), asked Charlie to run some equations for a home invasion case. Later, Don, Nikki, and FBI Special Agents David Sinclair (Alimi Ballard), and Colby Granger (Dylan Bruno) stake out the next target predicted by Charlie's equations. The team rescue the couple inside, Sara and Gil Fisher (Debbon Ayer and Michael Gaston), as the home invasion takes place. During a shootout, the home invaders escape. While Don and Nikki check out the backyard, a fifth man (Michael Khmurov) emerges from the Fishers' guest house and stabs Don. Charlie rushes to the hospital, joined by his girlfriend and colleague Dr. Amita Ramanujan (Navi Rawat) and his and Don's father Alan Eppes (Judd Hirsch). Charlie wants to stay with Don, but Alan tells Charlie that Don would want Charlie to continue working on the case.

Stunned by their team leader's injury, the team, including FBI Special Agent Liz Warner (Aya Sumika), proceed with the investigation, with David, who had recently been promoted to primary relief supervisor,[1] taking over for Don. Meanwhile, Assistant United States Attorney Robin Brooks (Michelle Nolden), Don's girlfriend, arrives at the hospital from a conference and stays with Alan while Don is in surgery. A partial print found at the scene leads the team to Los Angeles Unified School District's 2007 Teacher of the Year Tom Kardum (Shea Whigham), who is a suspect in the disappearance of an investment banker. Kardum denies any knowledge of Don's attacker. After the surgery, Don goes into cardiac arrest and temporarily flat lines as the doctor explains the extent of Don's injuries to Charlie, Alan, Robin, and Amita.

Meanwhile, the team learns that the home invaders, who had no previous criminal records before the home invasions, all lived in the same town in Croatia. While visiting Don in the hospital, Charlie confides to Alan that he feels as though he rushed the FBI work to return to work on his cognitive emergence theory. Alan's response is to tell Charlie to set some priorities. Back at CalSci, Charlie and Amita realize that all of the home invasion victims, including the Fishers, had remodeled their homes about the same time that the investment banker started his latest scheme. They also learn that the home invaders' true target was Don's attacker. The Fishers are brought in for questioning, and they tell the FBI that the investment banker asked them to help hide Don's attacker. The team then learns that he was Slobodan Radovic, a Serbian war criminal who had murdered the home invaders' families in Croatia. The FBI team also learns that the investment banker, through an intermediary who is found murdered during the investigation, wanted to pay Radovic in diamonds.

After seeing a still from a confiscated surveillance video, Charlie replicates a key to the investment banker's safety deposit box, which is at a jewellery store. Unaware that the investment banker and the intermediary are dead, the jewelry store owner (Alan Blumenfeld) assumes that Charlie, who is there to look at the diamonds, is the intermediary and lets Charlie have the diamonds. Charlie then confronts Radovic, stating that he wanted to see the face of the man who stabbed his brother and just as Radovic is about to attack, Liz, David, Colby and Nikki all wielding guns with their lasers trained on Radovic arrive and after a stand-off, the team arrests Radovic.

Some time later, the team, Charlie, and Amita visit Don, who is now awake. Don informs the team that he can return to part-time desk duty upon his release from the hospital and that he can return to full-time work in a few weeks. After everyone else leaves the room, both brothers agree that neither of them initially wanted Charlie to experience Don's life. As Charlie leaves Don's room, Charlie tells his brother that Don would see Charlie at the FBI office.
