Shannon was the red herring in the story that had Lucinda dreading meeting some woman. It was revealed that the mystery woman wore a green scarf and Shannon was seen often wearing a green scarf. She often showed up at Lucinda's asking to see her.
We also knew Shannon liked stingers; she was bombed on them the night she met Duncan and married him.
So when Lucinda went out to Rudy's tavern to meet the mystery woman, who, according to the bartender, was on her 'second stinger' it was expected that she was going to see Shannon. Instead, it was Iva -- who ALSO drank stingers (you can see the drink at 4:08 in the clip).
Doug Marland, being a detailed writer, didn't just drop Shannon wanting to see Lucy; they finally connected for a valid reason: Shannon wanted to sell her Walsh stock to hire a private eye to help locate Duncan -- Lucinda, in turn, took the info of Shannon being in a financial jam and relayed it to her new bestie Barbara.
Layers, layers, layers. And if something was added, there was a reason. Such weaving. Brilliant.
If you look carefully, you can see Iva ALSO wore a (very very pale) green scarf.
Once Iva came home from her first meeting with Lucinda, she covered to her mother that she was meeting with Steve to which Meg pointed out: 'gee, that's funny; he just called and didn't know about any meeting.'
Viewers suddenly saw something that had been there all along. Meg (boy was Jennifer Ashe great in that role) blasted Iva before the truth came out she was Lily's mom: "Your world revolves around Lily Walsh. Mine doesn't."
Doug was always planting seeds. Today, one of the remaining soaps, Y&R, tells all its stories off camera -- Traci visits Dina (off-camera) in the Alzheimer's home. Adam tries to figure out if Victor killed someone years ago (off camera). the new kid's grandfather dies -- you guessed it -- off camera.
I highly recommend watching on YouTube Atwt 1986, perhaps Doug's finest year ever after taking GH to the top in 1978 and 1979.
