Season 6: Episode 10 - Green Thumb

Green Thumb: A computer programmer who helped write the code that protects the Federal Reserve has gone missing, and the FBI fears the worst. Abbott and Fischer decide to enlist Jane's help, albeit reluctantly – his case closure record at the CBI was second to none, but they don’t want a loose cannon on their team. Jane has been cooling his heels in a jail cell for the past three months, but when the FBI brings Lisbon on board he agrees to work the case.
