Love Maison Blanche. I go back and forth all the time about whether that or Aremid is my favorite. I think Maison Blanche pushed more story for multiple people-Stefano's return, Hope's return, Bo/Billie, Tony/Kristen, Peter/Jen, the end of Roman/Marlena etc than Aremid did.
I still like the Susan story if only because I thought Marlena/Kristen were gold in the Secret Room. It was clearly the beginning of the end though with John and Marlena being very dumb by not figuring Susan out and the fact that they were clearly in love with one another. There is dragging things out and there is John missing the most obvious social cues every day of his life. The Elvis wedding was like the precursor to the wacky Jonesy stuff. Neither were as funny as JER thought.
A John Kelly Genovese article online from back in 1979 claims that Ken Stevens died in a car accident. The article covers some of the final storylines, including Laurie and Mark moving into a supposedly haunted house.
