Brian was a recently graduated computer programmer working several low-paying jobs before he was approached by Linderman, who offers him a job at the Corinthian Hotel. Brian's first task is to design the hotel's website. Later, Linderman enlists him to rig an election in favor of candidate Nathan Petrelli. Brian uses a "logic bomb" to rig the voting machines but when it fails, Linderman is furious. Brian runs away, makes his home in a nuclear fallout shelter, and gets a job as a blackjack dealer in a small casino. As he watches the demolition of the Corinthian and learns of the death of Linderman, Brian writes in his blog, wonders who ruined his life, and vows revenge.
In a video on Hana's website, Brian discusses Mr. Linderman's plan to use a logic bomb to fix Nathan Petrelli's congressional race with Kelly Shoemaker. The two initiate a test of Linderman's voting system with Walter, a New York election official.
