There's Always A Blue Sky in Your Heart

The children are forced to put their plans to re-visit the ruins on hold when Luna develops a high fever. On Chako's advice, they split up to search for medicinal foods and plants for her - Chako and Sharla look for an arrowroot-analogue, Bell and Shingo look for mugwort, Kaoru goes to get eggs, Howard looks for fruit, and Menori remains behind to take care of Luna. The hunt for arrowroot is difficult, worsened by the arrival of bad weather, but Sharla insists on continuing, even after badly scraping her knee. Sharla wants to be strong for Luna, so Chako tells her the story of her first meeting with Luna, shortly after her mother died. Chako tells Sharla the secret of Luna's strength - to remember that even when bad things come, there's always a blue sky in your heart.
