The basis for "The Equalizer" is in its name. The concept of quid pro quo despite an end game that is very finite. When we last saw McCall (literally in the middle of a storm), the idea was that the wolf will always be hunting. What is interesting in the forward plot of "The Equalizer 3" is the essence of human nature, including compassion, especially for a hit man in the time he finds himself.

The notion of self is an changing perception that runs all through pop culture but it has been present for thousands years but under a different name, context and perception: reincarnation. That perception is at the core of the story of "Infinite".
