"RETURN TO GLORY"
While in Mexico City, Alexander Scott picked up a silver gravy boat for his mother to give to the Westphalls for their 25th wedding anniversary. Scotty's partner Kelly Robinson knew this would make Mrs. Scott angry because she specifically said that she wanted to give them a silver chafing dish.
(Scotty is holding the gravy boat in that package, seen in the picture above.....)
This happens back in January, 1966*, so I think it's pozz'ble, just pozz'ble, to make the claim that the Wesphalls were the parents of Dr. Donald Westphall. (Dr. Westphall would one day become the head of the Boston teaching hospital St. Eligius.....)
I also think Mrs. Scott is mistaken about which anniversary was being celebrated by the Westphalls. In order to keep Dr. Westphall from being a bastard, she probably meant the 35th anniversary. She may have even said it and Scotty didn't hear her correctly.
If that's the case, a nice jade gift from Mexico would have been more appropriate.....
* The episode aired in February of that year, but it would only be the framing device of their argument for getting reimbursed that took place early in February. The story they recount about the "Glass Pants" expenditure took place the month before.
