There were indeed scenes cut/trimmed from this episode as a few of the sequences have been restored on the MPI VHS. I don't honestly remember what they are at this point because I haven't watched all of the '91 series since its 10th anniversary - and neither the series' concordance or the DS Resurrected book detail what they are. I suppose we'll just have to watch the broadcast version and then the MPI version to pick them out. Though even at that it won't be everything that was cut because, as I alluded to with the montage, some of the stuff that was shot for this episode was never made a part of it in any version.
Sadly, scenes were cut/trimmed from just about every ep. I'm still surprised that no one has mentioned how a certain actor's name appears in the opening guest credits for Ep #4, yet he is nowhere to be seen in the ep (though a photo of at least one of his scenes does appear in the DS Resurrected book).
And as far as the excursion to 1790 goes, we probably shouldn't blame the writers because they were of a mind not to go there in the first season. It was DC who insisted that had to be done. And just wait until I get a chance to post an article the goes into DC's involvement in the scene in which Trask is bricked up...
