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.
It's really amazing how they've managed to mess up every story beat with Jason/Carly/Sonny. One thing that bugged me this week was that they finally had Kristina on and voicing opposition to the wedding AFTER Jarly got married. Where the heck was Kristina during this entire engagement? It would've been great to have literally just one person in Port Charles not supporting the wedding and being like, hey, this kind of feels like a betrayal to Sonny. But nope. They only trot Kristina out for one episode for the reunion scenes.
I will say that I liked Sonny having a flashback to Mike kissing Nina. I'm not even into the two of them together, but Sonny still having some of Mike's feelings for Nina is at least soapy. This is a far more interesting beat to play than Jason and Carly trying to deal with their insta-love that developed off-screen and hours before the wedding. That drama feels so forced. We at least saw "Mike" and Nina's connection develop over several months, so it's more believable. Imagine Carly finding out that Sonny was in love with Nina in Nixon Falls and that he can't shake some of his feelings for her even though he has his memory back now. I'd much rather see that than Sonny getting angry that Jarly decided to try for a real marriage hours before the wedding.
Marlena had DJ fairly early in her run and no kids that popped up unless you count the Gemini Twins which weren't really hers. In the scheme of things her child count is pretty low with only 3 living children, but John and Roman were the ones with kids coming out of the woodwork. Although I would not be shocked if someday a 1986 Jarlena baby turns up (as long as it's not Ben)
