I apologize if my memory is playing tricks on me. As I recall, when first introduced, Tim mentioned his father traveling for work (owning a medical supply business) and mother traveling with him. Though on the plane it looked like she worked the business, too, rather than just traveling with to me. In any event, I only recall that occupation at that time. Then later, there the archaeology background. Was that there initially? I know I saw it fairly early in Dixon run of Robin, but am not sure of it's initial presence. If not, when was that element introduced?
And do you have a preference or care at all what profession the Jack and Janet had?
