Two people who had every reason to stay defended — and chose, instead, to take the armour off. To rise from what burned them down, rebuild from the foundation, and do it in the open. Undefended, and unstoppable, at the same time.
That is the whole of it. The rest — the work, the films, the climb — is just what two people build when they stop being afraid. (Even the dogs answer to Ember and Onyx.)
