The Mandalorian and the Kid are archetypes of the Wounded Warrior and the Inner Child - recurring characters in historical lore.
Both are expressions of the Self.
I have lived three decades as the Wounded Warrior and forgot about my Inner Child.
Now I'm protecting my Inner Child with my Wounded Warrior until both become me. The Wounded Warrior protects the Inner Child, the Inner Child heals the Wounded Warrior.
