Complete story — includes the ending
Abbott's former boss in Rio Bravo, Bill Peterson ( Dylan Baker ) digs up the evidence to convict Abbott of the crime he committed in Rio Bravo by finding the bullet used to kill the mob enforcer. He plans to use it against him during Lena Abbott's ( Christine Adams ) evaluation for the post of Under Secretary of Commerce also convicting Abbott of the murder. Jane, who has been monitoring Peterson through Wylie, gets a whiff of the plan. The team, consisting of Jane, Lisbon, Wylie, Cho and, later Vega, fight back by seeking evidence of Peterson's corruption and realise that for 20 years he has been skimming drugs and money making up evidence, doing so during the busts he had been leading. Meanwhile Peterson meets with Missy Brammer, the Legislative Director to a congressman, who is going to evaluate Lena for the post and gives her the bullet as evidence. Jane and his team find unlicensed weapons at Peterson's house but cannot access the skimmed loot at Peterson's house because it is in a safe that needs his biometrics to open. Jane instructs Wylie to borrow money from the FBI's evidence locker to plant as if it was Peterson's stash - Wylie has to confide in Abbott to obtain high enough clearance to achieve this; meanwhile Vega delays Peterson as he heads home, long enough for the team to succeed. During the morning of the hearing, in an altercation between Abbott and Peterson, Abbott shows the "evidence" he has against Peterson (photos of the weapons, cash and, to prove the location, his cat). This leads to Peterson trying to make a deal with Abbott: a share of the money in return for the evidence, but Vega secretly records the conversation. Though defeated, Peterson is happy that Lena will never get the Post as the evidence against Abbott has been passed on to the congressman. However, it's revealed that Peterson never met with the real Brammer but with Samantha Barsocky (Tangie Ambrose), a friend of Jane's, who posed as her, thereby acquiring the evidence against Abbott. Peterson is arrested. As Lena has now been confirmed for the post, Abbott will be moving with her to D.C. soon, and he tells Cho he will take over the team.
