No Nukes Is Good Nukes

S4, E1: On leave from his ship, Commander Robert Powell visits the family for the first time since Charles has been with them. Concerned about making a good first impression, nevertheless Charles starts off on the wrong foot when he cannot account for Adam and Sarah's whereabouts. He sets out quickly to find them while Jamie covers for him. Adam turns up coated with mud, but Jamie is nowhere to be found. Still trying to impress the commander, Charles sides with him when he tells the family of his frustration when a group of anti-nuclear activists whose protest against his ship almost prevented him from visiting his home. Jamie secretly teases Charles, reminding him that just that morning he had told them of how important protest has been in maintaining freedom and democracy in the United States. When Adam turns on the TV news, Charles finally finds Sarah in the crowd on the screen...being arrested for protesting in front of her father's ship!
