where you think the cage's door is: suicide or homicide
the difference between suicide and homicide consisting perhaps only in where you think you discern the cage’s door: Would she kill somebody else to get out of the cage?
Context
The both-cages logic pushed to its darkest hinge: everyone in the cage is looking for the door, and whether the search turns inward or outward — suicide or homicide — depends only on where you think the exit is. Joelle, contemplating her own overdose beside a girl on the homicide-linked Love Drug, locates the theme's most chilling equivalence, the shared desperation to be out of the cage taking either direction from the same root.
