When Milo finally reaches the princesses, they explain the need for his trials in the Mountains of Ignorance. It was not enough that Milo learned the lessons of the Lands Beyond; he also needed to learn to put those lessons to good use. It is only when he does that he receives wisdom as represented by Rhyme and Reason. Milo, who once languished in boredom and felt minutes passing like days, has also discovered that "time flies." This proves to be a handy realization as the group uses Tock's ability to fly in order to escape from the Castle in the Air.
