The series also placed importance on the heroes and martyrs of the Marcos' martial law regime particularly on the episodes on Ditto Sarmiento, Remberto "Bobby" de la Paz, and Macli-ing Dulag.

At the end of each travel, the two schoolchildren return with the artifacts (in the case of the first episode, the first fan made by Andres Bonifacio) and presents them to the guardian, who later becomes a grandfather figure to the children.
