418: When Worlds Collide
A dedicated FBI agent, Don Eppes (Morrow) couldn’t be more different from his younger brother, Charlie Eppes (Krumholtz), a brilliant mathematician who yearns to impress his older brother. The two brothers take on the most confounding criminal cases from very distinctive perspectives. As a seasoned investigator, Don deals in hard facts and evidence whereas Charlie, a math professor at a California university, functions in a world of mathematical probability and equations.
102: Uncertainty Principle
When Don and his team attempt to catch a pair of repeat bank robbers in Los Angeles, Charlie devises an equation using probability and statistical analysis to pinpoint the location of their next robbery. Although his prediction for the next robbery is correct, his mathematical model turns out to be useless when the robber’s true motives are revealed. His frustration growing, Charlie’s desire to continue to help the FBI falters when a stake-out goes bad, leaving one agent dead and his brother, Don, with a gunshot wound.
When people start mysteriously dying in Los Angeles, Don and his FBI team are called in by the Public Health Service to determine if it is an act of bio-terrorism. Using Charlie's knowledge of the mathematics of diseases, they attempt to track the virus not only to stop it, but to find the point of origin in order to determine who is responsible and why -- only to be surprised by the motive of the suspect. Meanwhile, Don is surprised to learn that Charlie has been keeping a secret from him.
104: Structural Corruption
After an engineering student at CalSci is found dead from an apparent suicide, Charlie convinces Don to launch an investigation after he reads the student’s thesis that asserted that the architecturally magnificent Cole Center in Los Angeles is structurally unstable. Although reluctant at first, Don and his FBI agents discover that the student’s findings were correct and uncover a dangerous and surprising conspiracy. Meanwhile, Alan prepares for a first date and convinces Don and Terry to join them, hoping they might rekindle their old romance
105: Prime Suspect
When a 5-year-old girl is kidnapped from her birthday party, Don and Terry lead the investigation but must rely on Charlie's help, as the girl's father, Ethan, is also a mathematician. Charlie realizes the kidnapper's motive when Ethan reveals that he is close to solving Riemann's Hypothesis, a difficult math problem. If solved, the solution could not only earn him with $1 million but could break the code for Internet security, unlocking the world's biggest financial secret. Neil Patrick Harris ("Doogie Howser, M.D.") guest stars at Ethan Burdick.
While consulting with the National Transportation Safety Board (NTSB) at the scene of the wreck, Don learns that this tragedy is one of a series of recreated accidents involving railroad negligence. As is the pattern with the previous train wrecks, an undecipherable numerical code is left at the site, which Don recruits Charlie to solve. By breaking the code, Charlie is able to establish that this accident was a recreation of a deadly wreck that left only one survivor several years ago. Don's investigation leads him and his team to a dangerous standoff with their suspect, who has surprising ties to the railway system.

416: Blue On Blue
When Sam’s sister Natalie is threatened by her drug-running ex-boyfriend, Natalie turns to Spike for help. Without telling Sam, Spike steps up to protect her – and winds up in a trap that will force him to recover stolen heroin from a highly secure evidence depot. At the same time, he must square off against an even more dangerous foe: his own team. Putting the many losses (Lou, Oliver and his father), he has sustained recently, Spike deftly wins the confidence of the villains as he jams security frequencies, while simultaneously signaling the SRU where to rescue Natalie and himself.
417: Priority Of Life
Carelessly cooing in compromising radio conversations between one another, Sam & Jules are blithely unaware that Dr. Toth has been monitoring. The same day, Parker is suspended by Dr. Toth while Team One responds to a bio-terror call at a highly classified laboratory... where Jules and Sam are forced to make a harrowing Priority of Life decision: save a civilian, or Jules, from exposure to the bio-hazard virus. Sam chooses the civilian, but Jules emerges uninfected. Parker and Ed defend Jules and Sam. They maintain the priority choice Sam made today indicates they are the “exception to the rule.”
