You can use any quad anywhere because they’re all based on Knowledge, Thought, Ability, and Desire. It’s when you try to work them together across four different Throughlines that you have to start making choices to tell a complete narrative.
In the Jaws example and Piper example from my site I’m simply grabbing a quad of items and showing how complete working through a quad feels from a writing standpoint. Again, this is because they’re all based on KTAD–just masquerading under different contexts.
PRCO. SRCA. Again, all TKAD, just different contexts.
Piper isn’t a complete story. Six minutes isn’t enough time. It feels complete because it works through a single quad, so you feel the completeness of a dramatic unit.
