Season 2 was notorious for its "no one is safe" approach, killing off major characters to keep the tension at a fever pitch.

A central plot involves the "exclusive" hunt for Charles Westmoreland's hidden $5 million , which leads to a dramatic double-cross involving T-Bag.

Season 2 would not be tidy. It would be a chase that followed records and rumors from Panama to Prague, from a convent in Sicily to the marble halls of an American courthouse. New allies would emerge: a forensic accountant with a grudge against offshore banking, a disillusioned intelligence analyst with access to secure comms, and a federal prosecutor willing to risk her career for a chance at a whistleblower. Old enemies would adapt: T-Bag’s manipulations would splinter the crew’s trust; Mahone’s pursuit of justice would fracture into vengeance; Sucre’s loyalty would be tested by offers of reprieve.

William Fichtner was promoted to series regular as FBI Agent Alexander Mahone. In an exclusive look back at the casting process, the writers admit that Mahone was the necessary counterweight to Michael’s genius. While Michael is calm, calculated, and clinical, Mahone is brilliant but chaotic, battling his own demons (and a mysterious "Company" handler).

Before Mahone’s arrival, Scofield was always the smartest man in any room. Mahone leveled the playing field. As an expert in profiling, he was the first character capable of decoding Michael’s intricate plans and tattoos in real-time. Coupled with his dark dependency on prescription pills and a dark secret involving a buried body in his backyard, Mahone became a fan favorite and a perfect foil to Michael's calculated heroism.
