But we've seen all of these ghosts pick up objects and unseen, presumably move things like the ship, dollhouse, etc., so evidently they DO have substance!!

I second all of that!  Looking forward to the reports!!

Do we ever heard where/what Hallie's Mommy & Daddy are (I think we do, but I forget).

They were killed in an accident recently.  It's mentioned when her presence is first explained to Barnabas and Julia, and then she referred to it a couple of times when talking to Carolyn and Maggie, for instance.

How nice to have this back!!

I always figure that David and Hallie wouldn't really be playing with the toys, but when the spell comes over them, they do it.  Look how Hallie says all the "Carrie" things when there, and then later doesn't even remember it.  As to whether the kids back then would have played with these things, I guess we'll just have to assume they did!

As to the clothing, though, you'd think they'd remember that it's supposed to be summer!  Usually, one can assume it's any time one wants.  Except for thunderstorms, there's no hint of appropriate weather and they avoid all allusions to holidays.  But this time, they have a picnic, and today Barnabas asked David about his summer - so they are definite that it's summer.

When David pretends to be sleeping, he hurriedly pulls all the bedclothes up over him.  I suppose Collinwood (or at least the main house) could be air conditioned, but even though he's doing it as a cover-up, it did seem strange for summer.  But, then there's everyone else's clothes.  Julia, in particular, is constantly in those heavy suits!!!

That's very interesting.  I had always had McAfee, but Norton came with the new computer.  Pretty soon I have to decide whether to renew that or go back to the other.  So far I've had no problems with it!

HAPPY BIRTHDAY,

Well, the Professor is one who believes Barnabas' story and he even suggested sending Hallie away!  But, no, they both agree that's a BAD idea!!  It could upset Elizabeth?1!!  She's already been told all that's to happen.

And, David lives there, but since Stokes supposedly cares about his niece, and that's why he's having her live with these "nice" people in "nice" Collinwood, knowing that she's to turn into a ghost in 1970, I would think that he and Barnabas would both figure to get her out of there!!  Even if it doesn't save anyone else, at least it would spare her!!
