Julia fears that Barnabas will revert at Adams death.  There are so many off things in this episode. The view out the old house window shows a totally different grid pattern and window shape. Vickie wants a leave of absence that she talks to Roger about when his sister is her employer and then it seems she wants to go for just a few days. 

Barnabas catches Willie trying to kill the dead corpse pieces. Willie suggests using Vickie which would and should have been Adams idea.  Willie decides he has no homie but to kidnap Maggie.

It was nice that Adam got a new piece of clothing.

Julia catches Jeff reading the experiment book and she gets all in an uproar when it would make sense he should know all he can to help with the thing.  Vickie has no trust in Jeff and breaks the engagement. She should has stuck with Frank Garner.

In the reenactment of the scene, Elizabeth's door is closed and Carolyn comes in and then shuts it.  There is an afghan on the bed.
The whole Elizabeth needs help conversations seem strange given that Julia is her doctor and living in the house and said it would be fine if she stayed there. Elizabeth has a beige phone in her room instead of the basic black everyone else has.
I love that Elizabeth has thought of all the possibilities of being buried alive and will have air vents and a buzzer in the coffin with a quick release lid. 

The whole life force issue brings to mind was Barnabas really living?  It would be interesting if Adams supernatural abilities came from Barnabas so that Angelique's. Ploy would have some merit. Or they create the mate and she is ordinary.  We learn Julia installed a generator. It must be large to power all that equipment and loud.  Adam in the window making Jeff look a fool to  Vickie was the best part of that scene.

Angelique thinks of Barnabas and payback. This storyline was my first exposure to Angelique and even as kids we caught on that she was in love with Barnabas.  It's really quite funny to think that Barnabas is able to steal away Joe who she is deeply involved with at this time.  Nick forces her to call back Joe after the alienation of affections occurs.
