I sincerely hope that Ms. Moltke didn't get pregnant just so she could get out of her contract, but I suppose that even though she would deny it, it might very well have been in her subconscious. She was newly married and I imagine she and her husband wanted to start a family anyway.
Her baby boy (Adam--yes, Adam!) was born on DS' 2nd anniversary, June 27th, 1968, both facts which make me smile.
As for playing a villain, I think Alex Moltke would have been fine at it. As someone pointed out, we never did get to see her bad side, but even the actress herself insisted she had one--and I bet she would have enjoyed releasing it. Perhaps she could have had an evil, slutty twin! They would have been able to work the pregnancy into the storyline with Vicki's twin sister coming to Collinwood, not sure who the baby's father is. Liz was both girls' mother,of course, but didn't KNOW she'd given birth to twins! Imagine the soap opera consequences then!
The mind boggles.
Love, Robin
