No one has come to the idea that Julia might have hypnotized Maggie to forget what happened. Now if Vickie was smart she would think this. She has seen the necklace before when she was at the Evans cottage and Julia had brought it out.
Vicky's doesn't know that Miss Hoffman is Dr. Hoffman, so she doesn't see any connection between Maggie and Julia.
Suddenly Sarah seems much more grown-up than she has in previous episodes - giving orders to David.
I didn't think of much of Vicky when David persuaded her to let him go out for an hour. I remember how Jason was able to manipulate her in their last conversation together by suggesting he had information that would interest her, and here David was doing the same thing. And then she didn't confirm the time with him, and and she didn't make sure he had a watch on.
Later, though, I was impressed with Vicky when she manoeuvred Burke into investigating Sarah by pointing out to him that investigations were what he's supposed to be good at.
I just loved the way Burke was the one who unwittingly obstructed David's pursuit of the awful truth about Barnabas.
