In "Cocoon," after Wo Fat (Khigh Dhiegh) leaves the SS Arcturus, the traitorous intelligence agent, Miller (Andrew Duncan), goes to the ship's captain (Wright Esser) and presumes to tell him when to cast off and to ensure that McGarrett's body does not float back ashore, as intelligence agent Hennessy's did.

went to the chief priests and said, 'What are you willing to give me if I hand him
[Jesus] over to you?' They paid him thirty pieces of silver . . .
