I found these techniques in Solar System
on the internet, but they seem universally valid. *edit : or rather, we can try to see what is generally valid about them.* I thought I'd propose them to your attention.
para tu compilacion de técnicas :Dramatic coordination :
A) Linking characters X and Y
a) direct link : X-Y
b) introduce common element : X-Z-Y
c) indirect link : X=Z-Y (=:existing link, -:new link)
Using (a) in the middle or end of a story is felt as a Deus ex Machina and (b) is slightly less "brutal". The linking is less noticed as artificial by the audience if it occurs during preparation or early exposition, when the audience is somehow under the influence of infodump pain killers. Adding (c) on top of (a) and (b) increases the resistance of the link.
'B) Framing scenes relevant to goal : having the goals stated or even, written in plain sight.
C) Resting : Take a Refresh, lower the stakes, put your princess dress, stall story progression, relieve creative strain by lowering the necesity to "deliver", thus opening a door for new perspective, narrative material and goals.
