Nobody knows for a Fact that the man running across the Knoll is Darnell. You are assuming the 3 Women did Not Stop while walking across the Knoll. Foolish assumption. To this point, No One has been able to explain Why there is a time gap between the film snippet showing the 3 Women at the Top of the Knoll vs the film snippet showing them at the Bottom of the Knoll. 2 Different people filming the 3 Women with different cameras/film would explain the Time Gap between the 2 snippets + the Definition difference between the 2 film snippets.
