Well I am still trying to figure out this whole “Jessica I should have married you” inner voice monologue before Leto dies.
The scene where Alia is conceived is not a fladhback…It is correctly placed but should be proceeded by the cliffs and the water swirling I think.
My feeling is and this is I think more accurate.
The Leto inner voice about marrying Jessica goes over the deleted scene where she is holding the note and shadout mapes enters. I would also imagine that corridor shot prior to conception of Alia from EE preceeds Jesdica reading the note or putting down the note to give enough time for the monologue. There could also be surreal images here also. Water and waves would be a good choice. Missing home. I can not confirm this but it would make that scene work and Leto going to his death with no monologue would not hurt.
Leto would go to his doom without any innervoice preferably but the script states "Jessica, my dear Jessica wish that we were somewhere else, anywhere. Away from this terrible place. Alone the two of us without a care " or something along those lines as the inner voice.
This also brought to my attention. Duke Leto’s inner voice from the EE “They tried to take the life of my son” Is intended for the deleted scene where Leto looks out the window to the sunset dusk and nightfall seeing the Harkonen signal light flicker and Thuffer enters to talk about city fremen Prophecy and being led to true freedom. This scene was to feature some action however of ships destroying source of the Harkonnen signal light. Perhaps The action was first then revenge and retribution as Leto looks out across arakeen and a threat eliminated. The World building is completely absent here and it obviously hurts the deleted scene in a big way.
