This is one of several 1795/96 eps that were infamously edited when they were shown on Sci-Fi - and not because of any glitches in the master tapes. In this one, everything from the point Abigail calls out Joshua's name after he reappears on Vicki's bed right up through Abigail fainting in Joshua's arms was cut.
Why? Well, only that "certain someone" who "tweaked" the eps for Sci-Fi knows.
But thank heavens we have it all on the VHS and DVD releases.
