She also sets up Ellen to take the fall for bribing the judge. Ellen, meanwhile, procures a handgun. After destroying the FBI cameras in the room by shooting them, Ellen confronts Patty about her actions from season one, leaving to bribe the judge after Patty confesses that she was responsible for the attempted murder of Ellen.
