Follyfoot S01 E13 A Day in the Sun

In search of his mother, Steve visits his grandmother. While there, he is told of a badly injured horse and he takes it back to Follyfoot. The horse is so ill it has to be shot. Steve leaves Follyfoot to continue searching for his mother, much to Dora's distress. She collapses against the lightning tree and is dragged away sobbing by Slugger.
