(Strip Number 6685, Original Publication Date, 21 October 1984)
Panel 1: We find Elly and Lizzie walking through the park on a nice autumn day; having noticed that there are a lot of falling leaves, Lizzie asks Mommy if there are eight zillion, kafillion, kadillion, kajillion leaves in the whole entire world.
Panel 2: Elly's response is a breezy sure-why-not?
Panel 3: We begin the strip proper by Lizzie noting that the leaves sure are pretty this time of year.
Panel 4: She then reminds Elly that they both know why.
Panel 5: As Elly starts to explain that during the spring and summer, the leaves make food for the tree, she doesn't notice that she's starting to lose Lizzie mentally.
Panel 6: She also doesn't notice that explaining that when it gets too cold, the tree goes to sleep and cuts off nourishment to the leaves is leaving Lizzie cold.
Panel 7: She finishes off by telling a baffled and upset Lizzie that as the leaves die, they change colour according to the species of the tree.
Panel 8: A downcast Lizzie mutters "Oh...."
Panel 9: She then tells a baffled Elly that Grandma said God paints them one by one.
Summary: Having read the Lynnsight and having remembered any number of strips in which John and Elly get their bowels in an uproar because the children's "innocence" will be lost if they know the truth about anything, it seems to me that we're supposed to think that knowing How Things Work somehow leads to Lizzie being so filled with rage and defiance, she wants to dress up as a punk rock chick.
