Betsy Durkin was a very different sort of type as compared to AM. Alexandra Molka was a European aristocratic, a refined cool beauty and Durkin a more aggressive, nervous type. In many ways Durkin did seem more of an "orphan", nervous, insecure, a little rough and tough who looked like she may have had a hard childhood who had to fight and scrape (if you read about orphanages back in those days). Though I think AM a fascinating choice as Vickie, in reality, though, I couldn't see her raised in a fondling home. AM came from old money and family and looked it. But, at least she never shoved her refined nature in our faces. She was happy taking the back seat and subtly allowing the rest to shine. That's why AM made the character work.
