Follow the stories inside the story
A, B & C plots. One story that holds together.
A repair, a fractured relationship, a hidden mistake. Follow three storylines through The Last Light and see what changes when the B story goes missing.
- A
The repair
Can they restore the light?
- B
The siblings
Can Mara stop deciding for Eli?
- C
The secret
Will Kit admit what he did?
Eli winds. Mara holds the connection. Kit tells the captain the truth.
Three questions, one ending
The subplot has to change what happens.
Mara cannot fix the lighthouse by being a better engineer alone. She has to listen to Eli, and Kit has to tell the truth. The ending needs all three stories. That is the difference between a subplot and a detour.
Inside The Last Light
Where the stories meet
Choose a scene to read it. Filled marks show which stories it advances; empty marks show an absence.
Watch the decision change.
In scene eight, the brass band solves the same mechanical problem in both drafts. Only one version advances the relationship.

She waits. Eli removes the band and gives it to her.
ELI
Then let's use it.
The same practical problem, a different way of solving it. A change in the relationship becomes an action we can film.

Questions for your next revision
A plot is a question that changes
A: can the siblings restore the beacon before the ferry turns back? B: can Mara stop deciding for Eli? C: will Kit admit the damage he caused? A label helps you follow the question. It cannot make an unrelated scene into a subplot.
A scene can carry more than one story
The clock repair advances A and B together. Mara's way of solving the practical problem initially worsens the relationship. In the revision, asking Eli for the brass band moves both stories forward. That is why the same scene can have several labels.
Subplots and parallel plots are different choices
A subplot supports or complicates another story: Eli's relationship with Mara changes how the repair succeeds. Parallel plots give two or more strands their own progression, often alternating viewpoints or timelines. Imagine alternating the lighthouse repair with the ferry captain's decisions: a passenger needs shore care, worsening water closes one route, and the captain must choose whether to wait for the beacon. Each strand develops its own pressure before the light brings them together. Cutting between two locations alone does not create two plots; each strand needs consequential choices. The complete script above demonstrates integrated subplots, not that expanded parallel narrative.
Compare the missing middle
In the weak version, scenes five, six, eight and nine contain practical repair steps but remove the siblings' changing decisions. B appears early and returns for the reconciliation without earning it. Open Compare this revision beside those scenes to read both versions together. Then follow B through the complete script: the repair should depend on the relationship work you restored.
Use the labels to ask better revision questions
Open the example in Plot and use the Plot lines panel to follow B on its own. On your own script, label scenes by the question they change, then inspect a storyline's returns and quiet stretches. A gap is a prompt to read, not proof of a structural error. Some stories benefit from an absence; others lose the pressure they need.
Keep the version you are testing
Before a structural rewrite, name a save point. Try the alternative on a draft line, compare it with the original, and incorporate the complete version you choose. Writer gives that recurring revision work room to grow. The useful test is whether you can explain what changed in the story, not how many labels you added.
