Vickie appears to be holding school supplies.  Can she really be teaching?  Well she attempts to.  David reads well. David is consistently off task asking if Vickie ever tried to kill someone and what would she do if she tried to kill someone.  Perhaps there is a theme developing here?  David manages to touch the wrench even after Vickie tells him no.  Unfortunately I know too many teachers like Miss Winters.

I was thinking about calling Elizabeth a witch and it must be an offshoot of fairy tales where the wicked old witch lives in the woods as a recluse and she doesn't seem that she would be welcoming of children tresspassing on the estate.  I wish they would have said what the reasoning for sending Carolyn to school in town was and not sending David.  Elizabeth seems very protective and if Carolyn came home crying she would say enough and hire a governess. 
Vickie believes Burke.  Why?  She barely knows him.  I know he's supposed to be the Heathcliff character, but the only thing he's done for her give her a ride into town and warn her away from Collinwood.   
Elizabeth evades Vickie's questions again. 
Lydia, I think that part of the reason that the Burke story doesn't work well, is that, Roger is not the person who owns Collinwood, the cannery, and the fleet.  He really has no reason to go after Elizabeth.  It would work much better if he and Elizabeth had been involved and he expected to marry her and then her father broke it up and he was bitter because she let it happen.  This would also make Elizabeth's worry about Burke and Carolyn more effective.

The sound of the foghorn in the background is a nice touch.  I keep thinking couldn't they spare some Blue Whale customers to populate the diner. 
So Roger was a witness against Burke and he swore revenge on Roger and the Collins family. 

Elizabeth loved her father very much and he died over twenty years ago about the time Vickie was born.  Could there be a connection?  So Roger was probably a minor when his father died, but apparently left him no money or if he did it was gone by the time Liz had to pension him off to Augusta ten years ago. 

yes, i noticed the table also.  If the set floorplan is followed, its front edge should  line up with the opening of the drawing room door.  Also the phone in the hall has been magically disappearing.  I just noticed the light switch in the drawing room is behind the right door later it will move to the left side and even later farther out on the wall, but what does it control? There is no overhead light in the drawing room.  Matthew must be keeping pretty busy because I would think moving that table would come under heavy lifting.

"I won't let you send me away"  Great line and "A terrible man I hope he dies."   And then ,"I'm not nice at all."  David watches from the window as his father goes off to die and then again talks to his mother.   
In the voiceover Vickie states that she made friends with David.  I wonder?

Burke's trial was held in Bangor for some reason and he was convicted of manslaughter and that Burke was involved with Rogers wife who married Roger the day after the conviction.  Roger and his wife never lived at Collinwood and resided in Augusta.
Matthew mentions that you need strong nerves and good brakes to live at Collinwood and that he crashed.  We later see his car which has a smashed front end and then Burke is in the garage with a wrench by Rogers car.  Can one  guess what is going to happen? 

A wing back chair appears in place of the grand piano in the drawing room and is put to good use foar David to hide behind and Elizabeth to sleep in.  The Robot seems so out of place in Collinwood.  One almost thinks that David never plays with toys, but there are a few in his room. 
So Elizabeth sent Roger and his new bride away 10 years ago with the expectation that they never come back, but they must have visited as Roger and Carolyn are familiar enough to have a pet name for her and Elizabeth must have known David as he is the only reason Roger is allowed back in the house.  Roger really must have disappointed his father to hae been bypassed in all his inheritance to his sister.
