NARRATIVE THEORY ON ENDING SCENE OF RENT
Here, I am going to apply TZETAN TODOROV THEORY that suggest most narratives starts with state of equilibrium is which life is 'normal'. This state of normality is disrupted by an outside force,(an outside force is this particular is drug over-dose that almost claim the life of the characters) which has to be fought against in order to return to the state of equilibrium.
