Trinity
Barny assaulted Jack Bauer, posing as Dog Smithies, as he arrived at Dean Schrock's apartment. Dean, trusting Jack, allowed him in and invited him on their mission; to blow up the dam holding all of Los Angeles' water. Jack tried to foil the plan but was stopped by Dean, who then told Barny to kill Jack.
