One of the things I do actually love about this show is that when something happens, they do seem (for the most part) to follow through, no matter how long it takes. A great example:
When the show first started, the cast spent about six weeks all of which was, of course, one day at the Harmony fair. at one point, everyone went to visit the fortune teller, who was, in fact, a disguised Tabitha. When predicting Theresas fate, the fortune teller said that she would wind up married to a Crane, bearing a child and living within the mansion, but it would not bring her happiness. Well, thresa took that to mean she would wind up with Ethan, of course, thanks to her obsession. Two years later, it had all come true... although she was married to Julian, not Ethan!
And then there was last December, when they had four weddings in the course of a couple weeks... sure, only two couples actually got married, but still...
And then theres the four or five concurrent pregnancies, with all those damn dancing babies...
As for the shed, I remember after Liz went into the shed and discovered the secret (we never saw what it was, we only saw her reaction), the actress said in an interview that she imagined it was something horrendous, terrifying and a little pornographic. The writers at that time admitted that they had no idea as of yet what it would turn out to be...
