Terminology.

Action Code - An action code was created by Barthe as one of his narrative media codes. It means that it allows the audience to interpret and identify what is next to come during a film.

Enigma Code - Is the code where it makes the audience ask questions.For example: If a character dies in a film we do find ourselves asking 'who died?' 'How did they die?' 'Did they get murdered?' 

The Hero - Seeking something. (Saves the day)

Agent Of Change - A character who inflicts danger and causes the current story line to change.

Equilibrium - It's all to do with Todorov's theory of equilibrium. So the episode starts and everything is balanced (equilibrium) then something happens, the disruption, then there is a resolution and then the equilibrium is restored. This theory is applied to the narrative and can be found in most common genres.  

Disequilibrium - When the film starts going down hill and the action starts to occur to make the film body.
