In the first post I explained why I believe the episode is written in 5 acts (because the final scene of each act is turning point instigated by the main antagonist).
In this post I want to look at two things:
- The number of scenes.
- The length of scenes
Scenes in yellow highlights are scenes with the protagonist.
Scenes in red highlights are scenes with the antagonists.
Scenes in light blue highlights are scenes with victims.
Scenes which are two colours are a mix, i.e. red / yellow are scenes with both protagonist and antagonist.
Let’s look at Act 1.

So, what can we notice?
First, there is quite an even balance of scenes between the protag and antag: 8 / 7.
The minutes of screen time are also equally balanced: 9.39 / 9.20
Victims inhabit only two scenes and 1/3 of the screen time of protag / antag at 3.31.
Secondly, almost exactly half-way through the act, scene 8, we are introduced to the main victim, Ann.
Please let me know if you notice anything else.
