This is something I posted in Part 3 comments which I think helps to frame the discussion here re the psychological journey in Argo:
There's that Nietzsche quote: "Become who you are." That sums up beautifully the essence of metamorphosis. Ovid wrote in "The Metamorphoses": "Every shape that's born, bears in its womb the seeds of change." The Core Essence of a character's Self Identity already lies within. It is the Call To Adventure to the specific journey upon which they embark that is the Universe's way of compelling the character to deconstruct the Old Way of Being and reconstruct into a New Way of Being, allowing those seeds of change to emerge into the light of day and blossom.
So Maximus (Gladiator) gets in touch with his inner gladiator in order to exact revenge. Katniss Everdeen (The Hunger Games) gets in touch with her inner warrior in order to lead a rebellion.
Those are all epic stories. The paradigm is scalable. In Juno, she gets in touch with her inner adolescence which she has skipped to become what she thinks is an adult. In (500) Days of Summer, Tom gets in touch with his inner adult after experiencing the failure of his flawed, infantile notion of romance. Similar dynamic with Annie in Bridesmaids.
In each story at key points along the way, events happen (plot points) which create a physical and/or psychological threshold, in effect a choice: Go this way or that, forward or back? Those are all tied to the character's emotional growth, either impacting it or influencing it.
Again Character = Plot. We cannot look at screenplay structure as merely Plot. Character and Plot are - or should be - fused together. We're seeing that already in the very first movie in this series: Argo.
So where does metamorphosis occur in Argo?
