its own). Relations sour as New Bern scapegoats Jericho for its problems and the New Bern sheriff eventually declares war, leading to the season's climax. Several themes regularly addressed in the show include the gathering of information, community identity, public order, limited resources, the value of family, hardships of fatherhood and internal and external threats. The show also features several mysteries involving the backgrounds of major characters, the perpetrators of the attack and the extent of damage to the United States and its government. The pivotal character in this story is Jake Green, the 32-year-old son of Mayor Johnston Green.
