You got the crash photos?
This graphic is the fourth of six, but again it does not directly address the Ghosts video.
Also, the prior graphic focused on math, but this one doesn't.
I stopped short of trying to "explain" everything with words, since the graphic hinges on being able to intuitively "see" the connection between two Q drops that initially seem utterly disconnected.
To get there, watch the Promontory scene in the film, but also watch the Huron scene.
Q4564 was quite ingenious on Q's part.
He pretends to "explain" a prior drop in one way.
But in doing so he leaves clues to a totally different decode.
The next two graphics will pick up the trail from the last three and return to the Ghosts video.
