What if Miss Ellie had another child, a daughter? Emma Channing from Falcon Crest comes to mind. The Ewing daughter would be mentally ill and kind of 'awkward' like Emma. She would say insipid things that make everyone even Lucy roll their eyes. Despite this everyone loves her and is very protective. The girl would be J.R.'s soft spot. As evil as he can be, he turns into a teddy bear with her. She even talks him out of doing some of his dastardly deeds. That's his little sister, and God help anyone who tries to hurt her. Emma could pass as a Ewing. IMO she kind of looks like Donna Reed. Their scenes would be believeable to me. What are your ideas?
