While Jed tells Jane that Jethro is home, Elly has another driving lesson from Robert, though can't handle a car. Granny "operates" on Jethro by pulling the mortar out of his stomach. After that, Jethro has made a full recovery. But Granny scares Jethro off by talking about a wedding, and he thinks it is for him.

Drysdale returns the bank happy, and Robert and Elly are on their way to Vegas, when it is revealed she doesn't love him. The two return to the bank, and Robert reveals who he really is.
