He's in trouble at school when his father, Worf, gives his word as a Starfleet officer that Alexander's behavior will change. It takes a frightening confession from Worf before Alexander understands that he must learn to control himself or lose everything he loves. A Klingon is honor-bound to keep his word, at any cost.
