Dramatica, to my knowledge/understanding does not account for the denouement. The easiest way for me to explain is an example. With full credit to Mary Robinette Kowal for this sample flash fiction story that is widely available on youtube
Hydraulic fluid dripped out of the rollercoaster’s AI straight on to Chelsea’s jockey badge. Where the heck was that leak? If she didn’t manage to get the coaster back online before the race she’d have to forfeit her entry money. Not a gosh darn suggestion from the troubleshooter on her head’s up display had isolated the problem.
Fine, it was time to improvise.
Chelsea stuck her hand into the AIs guts and traced the slippery fluid up as far as she could go. The interior of the rollercoaster was still cold from sitting overnight in the cryo-bay. Condensation clung to the walls and mixed with the hydraulic fluid coating her fingers. She closed her eyes, trying to imagine the interior as she ran past the junction box, and sudden heat stung her fingers. Chelsea jerked back, cracking her head on the toolbox behind her. “Gosh darn it all to heck.”
Shaking her hand she glowered at the rollercoaster. “You know if I have to forfeit this entry money, I’m going to have to sell you just to pay rent and you’ll probably wind-up in scrap. She reached in to the chassis again. “Please, please, let me find the leak?”
Her headsup display lit up with what looked like a diagnostic message from the AI that was supposedly offline.
“The leak is from the thermocoupler in my right breaking mechanism but fluid dynamics make it appear to come from the manifold.”
Chelsea’s mouth dropped open. “If you knew that all a long…” She closed her eyes cursing her own stupidity.
Three years as an AI jockey, and you think she would remember that even in a rollercoaster the temperamental things needed the magic word. Next time she’d say please sooner.
The very last line is the the denouement. It’s the tick where the audience is sure that the MC/Protag really got the lesson/solved the problem of the story.
Dramatica, to my understanding has it’s last story beat when the AI helps and “problem is solved”.
There was a Sandra Bullock movie, way back, called The Net and it had one of the better denouements I’ve seen, where she’s planting flowers for her landlady because the whole point of the that film was RL matters.
hth,
