19. The Key

Lincoln's father, Aldo Burrows, arrives and saves him from Kellerman's assault on the road. Aldo tells Lincoln that The Company, which he formerly worked for, controls the U.S. government, and that it used Lincoln to punish him after he defied it. The police and Kellerman pursue the pair; Lincoln turns himself in to evade Kellerman as Aldo escapes. When Scofield needs access through the infirmary door, Apolskis, raped by Avocado, refuses to steal the key for Scofield, but Volek lures Tancredi into conversation and steals her key. Scofield makes a copy and returns it to the infirmary, but Tancredi notices the theft and changes the lock.

Apolskis slashes Avocado in the genitals. Abruzzi returns healed, frightening Bagwell, but he makes peace with Bagwell and prepares an airplane escape for the team. Abruzzi is also revealed to be the man instructing Savrinn to watch Donovan. Scofield includes Apolskis in the plan, but Apolskis reports it to Bellick, who finds the hole in the breakroom.
