Jack: Plans
built 606 days ago
Due to being undercover with Ramon and Hector Salazar for months, Jack received a heroin addiction, and he ... learned about Chase's relationship with Kim at the start of the day. With no other options, Jack was forced to break Ramon Salazar out of prison, with President Palmer and Chief of Staff Wayne Palmer knowing about Jack's plan. This would save Palmer from any political back fall.

Despite not knowing, Jack ran a bluff on Ben, asking him about the symptoms associated with the tumor. Ben learned he had been conned by Jack (who was only making an educated guess about the X-Rays). Ben later told Jack that he had a whole plan to break him, and make him want to save Ben, but that was destroyed when Jack figured out the job the Others wanted him to do. Later, Juliet sneaked a message to him via videotape indicating that Ben was a liar, and suggested he kill Ben while in surgery.

Jack was forced to execute Ryan Chappelle when it became one of Saunders demands. Eventually Jack used Saunders daughter Jane as leverage, and he got Saunders location. However, Saunders managed to escape when he kidnapped Michelle Dessler and used this as leverage against Jack. Tony was ultimately forced to step down, and Jack took over CTU. However, Tony escaped from the building with Jane, with a plan to exchange Jane for Michelle.
