Here are a few tips.
The point of the scene
If you step back, this scene is about one character trying to figure out what a couple of other characters are thinking, feeling, planning.
Getting the answer is really important to her; she knows they are upset, and now she's afraid of what they will do.
Ingredients for the scene
If you want to use this snippet as a model, you'll need:
- A main character
- One or more secondary characters
- A relationship between them
- A reason for why the main character wants to know (but can't easily find out) how the other characters feel
Example ideas
- Members of a team, and one has choked in performance
- A couple (or close friends) and one has betrayed the other in some way
- Coworkers who are planning a suprise, and the target suspects something is up
- Fantasy creatures negotiating over loot, but one side is scamming the other
Structure
- If you look closely you'll see there are four triggers.
- Three of them create loops, and one ends the snippet.
- Each trigger sets off a combination of feelings, thoughts, and sometimes behaviour.
To get started
All you need to do to write the scene is choose your characters, relationship, and reason for their being hidden feelings, and then set up your first trigger and follow your nose from there.
