Betrayal abounded on the first season finale of the rebooted 'Hawaii Five-0' (Mon., 10PM ET on CBS). McGarrett finally got a piece of the puzzle together when he realized the governor's duplicity and involvement with Wo Fat. This tied her to McGarrett's father's demise.
He even got an admission of guilt in the death of Laura Hills earlier this episode, for all the good it's going to do him. The Governor said she's loyal to the people who are loyal to her. It's a great philosophy, but one that isn't shared by Wo Fat.
He arrives in the nick of time with a taser to take down McGarrett, who had the governor at gunpoint. Now, what to do about him.
