Vicki would still be David's tutor, although she might face a life of lonely spinsterhood.

I always had this sneaking suspicion that Barnabas had something to do with Burke's "accident." Although I'm not sure how. It just seemed entirely too convenient.

I think Diana Millay was there as well, or maybe there was more than one?

I recently posted a story that attempts to fill in the gaps about what happened between Quentin and Maggie while Barnabas was in Parallel Time.

I was hoping to find the collection relisted, perhaps with more description and a higher starting bid. I'm almost positive this was a scam.

I agree that "something doesn't smell right."  One reason 1219 was missing in the first place, we were told, was that a backup copy was never made. It was never syndicated. We are lucky to have the series at all. Those kinescopes were not buackups; they were made for stations that wanted to timeshift DS. The network did away with the kinescopes a year or so before the series ended, hence the "lost episode." 

What bugged me from the get go was the fact that he never highlighted the fact that the "lost episode" was supposedly included.  I wanted to get a fresh perspective from everyone, so I made no mention of my reservations. I siimply asked what you all thought. Unless he reposts soon, I smell a hoax.

I read that some old episodes of The Tonight Show made their way into the hands of a collector. He retained the right to keep them, but he was told he'd be sued if he made the shows available to the public. The collector owns the physical tape or film not the rights to distribution or performance.
