has tracked Gretchen Morgan and James Whistler to Los Angeles. The pair are negotiating for "Scylla", a card/disc of important Company data, and Whistler kills its current owner rather than pay for it. Before he and Gretchen can finish their operation, Michael arrives, planning to kill them as revenge for the death of Sara Tancredi. Gretchen claims that Sara is alive, but before she can say anything else, the police arrive in response to a murder committed by Whistler. Unbeknownst to Gretchen, Whistler has copied the Card, keeping the original for himself, and giving the copy to a Company representative on the way out. When the General discovers this, he orders Wyatt, a Company assassin, to have Gretchen killed. Lincoln Burrows is still in Panama with Sofia Lugo and L.J. Burrows when Michael calls him. They discuss the recent events in Sona: the prisoners rioted, burning the place down and allowing Theodore "T-Bag" Bagwell, Fernando Sucre and Brad Bellick to escape. Michael also asks about how sure Lincoln is that Sara is dead. After the conversation, Michael is contacted by Alexander Mahone and Whistler, who are secretly working with Homeland Security to destroy the Company. Key to this plan is the Card, codenamed "Scylla", which contains information on all the Company's agents and operations, but can only be decoded from within an unknown facility. Whistler again hints that Sara is still alive when Wyatt arrives and attacks them, killing Whistler and retrieving the original copy of Scylla. To learn the truth, Michael travels to Chicago and contacts Sara's friend Bruce Bennett to find out for sure whether Sara is still alive, but gets caught by the police. Meanwhile, Lincoln, Sofia and L.J. are attacked by a Company agent. Lincoln kills the assassin in a fight, and gets arrested by the Panamanian police. Mahone returns to the home of his family only to discover that there is a police fence outside Pam's home. Fearing that something may have happened to Pam and Cameron, he quickly steps out of the car and runs towards the house, but the police officer stop him and tells him "that you don't want to go in there". Since he is still wanted in the United States, Mahone is immediately arrested as well. Michael and Lincoln are reunited in custody by Agent Don Self. Self is the HomelandSecurity agent who was working not only with Whistler, but with Aldo Burrows, in order to take down the Company. Unable to trust people within the government, Self arranges to have Michael and Lincoln be part of an unofficial, off-the-books operation to recover Scylla from the Company, with their freedom guaranteed when it's all over. The brothers refuse the offer. Bruce pays their bail, and when they're released, he reunites Michael with Sara, who has been hiding out from the Company in Chicago after being tortured by Gretchen. When Wyatt attacks the group at their supposedly secret hideout, Michael, Lincoln and Sara decide to join Self's team, believing that they can only be safe once the Company is destroyed. Also drafted into the team is Mahone, Bellick and Sucre - who were captured while trying to visit Sucre's baby girl. In a subplot, T-Bag is making his way from Panama to the United States, looking for Michael in order to get his revenge. He tries to get to San Diego, following direction written in Whistler's bird book, but his drivers steal T-Bag's money and abandon him in the desert with their overweight companion.
