With Commander Glenn now in charge of HMS Hero the ship prepares for a naval inspection. Assisting Rear Admiral Staunton in this task is Mark Nialls, formally much respected captain of HMS Hero. Nialls and Glenn have a slight rivalry between them so Nialls is looking forward to winding Glenn up with the Naval tasks associated with the inspection. He wanders over to the ship to sow a few rumours as to what they could be. The tasks, called 'evolutions' help to demonstrate teamwork and initiative as well as being very humorous.
