We're doing a re-watch now and we are on the Donna Reed episodes. We noticed two things: 1) They needed a Miss Ellie to hold some of the plot lines together 2) Ray and Donna seem to have very little to do. So, why not solve both problems at once? Why not use Donna Krebbs to hold the plot lines together? Let's look at what the writers needed: 1) Plot line one: Jaime. The writers needed Miss Ellie to confirm that Jaime could be Jason Ewing's daughter. Jaime said it herself on her arrival: "Ask Miss Ellie. She would know if I am telling the truth". Great! We are treated to exactly one line from Donna Reed: "You do seem to favor Jason." Well! Case closed, everybody! Why not use Donna Krebbs to provide the anecdotal evidence? Something along the lines of, "Sam Culver used to talk about the old days. With Jock, Jason, and Digger. He talked about Jason's daughter, and how Jason would take her out to the oil fields even when she was a little girl." 2) Plot line two: The matriarch who Lucy and Jaime could turn to for support and advice. The great thing about Donna and Ray are they are both a half a step apart from the family. This makes them the perfect people for Lucy and Jaimie to turn to for advice. 3) Plot line three: Staring blankly into space in every single scene. Well, that role was expertly filled by Priscilla Presley, who could stare off into space as if training with Donna Reed for years. So, my question is this: Why take a chance on re-casting such a popular character? Why not just leave Miss Ellie in Europe and allow Donna Krebbs to step in during these plot lines?
