Worf's Battle for the Klingon Soul (TNG: Birthright, Part II)
Worf and Toq return from the hunt, kindling the fire in their souls, making the young klingons feel alive for the first time, and proving himself to an ideological threat to the community Tokath wants to maintain, where the klingons are denied their cultural heritage so they can be more like himself and his brethren. From Star Trek The Next Generation S6E17: Birthright, Part II
