I have an idea I'm working on, and suffice to say there's a couple of major plot reveals involving two characters (who are most often seen together/near each other, i'll refer to them as DUO from now on) play a pretty big part in the history of why these plot points exist. However, in the "present" day story you would follow a different group of main characters, while DUO would be... let's say hidden in plain sight.
I want to have "flashback" type chapters where you're following DUO, learning small things about why the plot reveals happened but i'm running into a problem of how to WRITE and ORDER them.
For example:
Following present day characters, reveals would be A:B:C, each worse than the one before it. But for DUO, the decisions made to create these plot reveals were C:B:A, as in Plot C was the first thing they decided to do, and then Plot B/Plot A came as a result of how to accomplish Plot C.
For my writing: I'm thinking of simply writing DUO from the beginning of their involvement in the Plot C (although much of this would probably not go in the book except for glimpses), and then write much of their story between the creation of Plot A and the actual reveal (again probably not going to end in the book) that way I can have a realistic characterization that makes sense as to their involvement in the creation of the plots, yet also allow a realistic way for them to be hidden in present day.
For the book: I don't know how to order these things... part me is thinking of sporadically including "flashback" sequences in reverse order of DUO.
So we'd start with flashback at the end of Plot A creation... then multiple chapters nearing reveal of Plot A... another flashback but nearer to the beginning of Plot A, hints maybe of Plot B... Plot A gets revealed in main story.
Does this make any sense or am I making this too complicated?
