Yes, the sequence as it was depicted in the trailer definitely brought up a lot of interesting speculation - though some character that we had as yet not learned about was also in the mix with Vicki, Angelique, and Liz.

1972 - Roger (in response to a question about who David is):
'I have no idea. I've never seen him before.' Sure, Roger certainly showed annoyance towards David in earlier parts of the film, which is in line with how much of the film's plot is inspired by many aspects of the pre-Barn eps of the daytime series. But to completely deny him. Well, that goes even beyond how badly the daytime Roger treated David during those pre-Barn eps. Though, of course, the real worst is yet to come when the film's Roger makes his ultimate decision of what is more important to him...
