Oh, dear Dom! I had a similar experience -- my best friend's mother showed me all her DS scrapbooks from the original run, comprised, for the most part, of 16 Magazine clippings, including -- and those of you who know me know how much I love this photo -- the very famous shot of Cassandra, Adam, Nicholas, and a fanged Barnabas all looming over Vicki. When I think of DS, I think of that shot.
One of the clippings contained in the scrapbook explained that Angelique the vampire was also known as Cassandra, and I became absolutely entranced with her dark hair and, I suppose, her versatility (modern, Mary Quant-wearing wife and vampire vixen at the same time?!? What a wonderful idea!)
Dom, Gothick, and I should all form a Cassandra-forever club.
