As the pair approaches the castle, they see another knight riding down to meet them.
The Yankee reads the herald's tabard—it's advertising soap—and resolves to send out multiple knights with a similar tabard, thus slowly educating the populace about cleanliness (while undermining the Church's authority in the process). Dirt is evil, but apparently religious too—who knew?
The knight claims that they are approaching the castle of Arthur's sister, Morgan Le Fay, and her husband King Uriens.
The knight further bemoans his failure at getting anyone to use soap, and the Yankee reassures him by suggesting that they add another phrase to the slogan: "patronized by the elect."
The Yankee and Sandy reach the castle walls and are admitted—the Yankee doesn't expect things to go well, given Morgan's reputation as an evil sorceress.
They speak to the king and queen, and while they do so, a page delivering a golden salve to Morgan slips and brushes her knee. She responds by stabbing him… oh good.
The Yankee nevertheless continues to be charmed by Morgan, until he lets slip a kind word about King Arthur. Morgan immediately orders he and Sandy sent to the dungeons. Guess there's some sibling drama?
As they are led off, Sandy announces that the Yankee is "The Boss," which Morgan responds to with a combination of sweetness and fear, while the guards hastily excuse themselves.
