Lot's of comments I could make, let's see....
First I think Angelique truly DID love Barnabas (in her own twisted, warped way). She wouldn't have been so obsessed with him over two centuries over his wealth, when there were other plenty rich guys she could have leeched off on.
I loved how Vicki stood up to Cassandra. For all the times we make fun of Vicki for not understanding, when push came to shove she could really stand up for someone she believed in (Barnabas, Elizabeth) and come through for them in the cinch (David, Daniel). Even though Vicki did unfortunately get dumbed down during the 1795 story, I still have a great deal of admiration and affection for her.
Love the bitch slap Julia gave Cassandra.......I think it was only natural they should go from friendly acquaintances to bitter enemies because they were both obsessed over Barnabas, one woman wanted to help him, the other wanted to destroy him. This was bound to cause a lot of friction betwen them.
Also Cassandra was obviously aware from the start Julia had strong feelings towards Barnabas. She was evil, but she wasn't stupid.
