I never fully appreciated Nancy Barrett's talent until I saw the show as an adult. Her wide-ranging characters, ability to scream and appear to be any age she needed to be was amazing.
Millicent is ditzy, but not entirely stupid. She knows a lot more than others give her credit for. Being attacked by Barnabas completely unhinges the poor girl, no doubt about it, toppling her over the edge she was teetering on.
I remember reading a fan fic story in which Millicent, after Nathan's death and Barnabas coffin imprisonment, gives birth to a child that dies. Poor Joshua is forced to watch the poor, mad girl put through childbirth only to have a dead baby--and then Millicent dies, too.
Sounds like no one thought Millicent came to a good end.
And being brought up at Collinwood didn't do Daniel any favors, either, did it?
