Body Horror: Caroline considering amputating her leg after becoming ill, fearing gangrene.
For Want Of A Nail: Multiple friends and neighbors keep having perfect opportunities to help Caroline at every stage of the plot, but a series of increasingly far-fetched and frustrating Contrived Coincidences prevents one after another of them from becoming aware that she's in trouble.
Recycled Premise: Fans of Bonanza who watched this episode might have seen this episode was largely similar to Bonanza's "A Matter of Circumstances" (Little Joe becomes sick with gangrene.)
