Stardate: 47779.4 When Worf learns his son does not plan to be a warrior and will not take the Rite of Ascension as expected, he decides to take Alexander to see some Klingon culture. But once on the planet Maranga IV, they are set upon by three armed Klingons. But then a fourth Klingon appears, but he attacks the three, helping Worf out.
