Vicki had more spunk when she first came on DS, but with Burke, she meekly accepted everything he told her. In that case, I always felt she was searching for a father figure as well as a husband, which explained her attraction to a man so much older than she was.
What's really strange is that when I first watched the Peter Bradford-Vicki relationship in 1795/6, I thought him quite a romantic guy, but once he showed up as Jeff Clark--YUCK! He was obnoxious, silly, exasperating and just plain unappealing. (Shall I tell you what I REALLY think?)
Vicki is still a lot less spunky than she used to be (remember when she went up to Burke's apartment because he said he might be able to help her figure out her background--how scandalous!)?
Sad to say, Miss Moltke no longer wanted to play VW, and who could blame her? The original focus of the show was Vicki, and once Barnabas came on the scene, she was relegated to a back-burner character who couldn't understand and became a brainless twit. Perhaps she got pregnant on purpose, knowing it would help her get out of her contract? I wouldn't have blamed her!
Love, Robin
