I generally think of Brett as being Kevin’s ward, but the more accurate term would be page. A boy served as a page for about seven years; at age fourteen he could graduate and become a squire. A page’s duties were acting as a messenger, serving, cleaning clothing and weapons, and learning the basics of combat. He also received a more general education from his master.
The January 16, 1955 episode shows Brett at work.
Again, Brett shows his skills (combat training this time). While it might seem unlikely that a lad as young as Brett was shown wielding a crossbow, it was not unheard of—the wikipedia article that described a page’s responsibilities also states “The mechanical and long-range nature of [crossbows] made them almost the only medieval weapon which could be employed effectively by a youth.”
Meanwhile, young Sigurd—more squire than knight—is being conspired against by his supposed guardian, Gouda, who is using the thug Hunn as a means to his end.
