1. Scenes 1–17

   The Protagonist in his zone of comfort — a skilled, anonymous field operative, competent and confident inside the Kiev operation.

2. Scenes 18–20

   Broken by torture and 'killed,' he needs a new purpose; Fay offers one that transcends the nation-state loyalties that just got his team killed.

   He enters the wholly unfamiliar situation of Tenet — the wind turbine, the password test, and Barbara's proof that time itself can run backward.

   Mumbai, London, Oslo, and Amalfi — he adapts to the world of inverted physics and Sator's inner circle, paying costs (Kat's trust, his own safety) to get close to the target.

5. Scenes 145–158

   The Tallinn ambush succeeds — he gets what the mission wanted, extracting the plutonium '241' from the armored convoy.
