Perry's grand reopening of Smiley's was in July 1984.
I found this -- it's Maisie's first day (as well as Peter's!) and there is some kind of criminal intrigue involving a man who apparently frequents Smiley's. Around 15 minutes in a woman who works at the museum (I guess she must be "Mary Lou" -- not sure who plays her) gives a vivid description of the greasy spoon Smiley's. And about 24 minutes in we meet Smiley's and Maisie.
And then in 1983 Alma worked there as "Nell" and lived in Happy's Motel before her murder.
I never bought the Alex/Mindy rivalry as played by either Beverlee or Marj.
Yes, Alexandra was humiliated by Roger's affair, as well as his business fraud, but I doubt that Alex would personally blame Mindy. Mindy was too low in status and power for Alex to care about. She was clearly a pawn, and a mature woman like Alex would have understood that fact. Alex wound up spending far too much effort in trying to punish Mindy, and in my opinion, it was beneath her. I mean when Alan cheated on his wife, Elizabeth didn't get into a rivalry with Diane, she blamed Alan, because she was a smart and sophisticated woman. That's why I don't buy Alex caring that much about Mindy that she would waste years scheming to retaliate.
To me the interesting beat that got overlooked in that story is the idea that Roger was able to con Alex due to her naivete about business. When Alexandra was introduced she had no interest in working for a living, and certainly she didn't care about a business that Alan created, but was not her family's legacy (a fact that was often forgotten by later writers). However, I think it would have been an intriguing idea if Roger's scheme motivated Alex to learn more about business so that she would never be conned again.
