The Robinson party meets Quano, a stoic twelve-year-old alien boy from a warrior race who's on the planet for a survival challenge. Since Will is near his age, a fight-challenge is offered. Will has no interest in fighting without reason, but Quano wants the challenge, in part to prove his superiority but also to prove his worthiness as heir apparent to his often-absent father, ruler of their male-dominated race. Quano finally goads Will into accepting, but Will doesn't know that, if he wins, Quano's family with have to destroy him and all witnesses. Dr. Smith surreptitiously learns of this and, threatened into silence, works to wear Will down with over-training before the contest, to save their lives.
