1. Scenes 1–17

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

   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.

   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.

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

   He pays a heavy price for it — Kat is shot, the material is lost to Sator anyway, and he is left not knowing whether any of it mattered.

7. Scenes 176–213

   Recovered and re-briefed by Priya, he returns to a now-familiar situation — the Tenet operation — but changed, moving to Stalsk-12 with the full picture of what's at stake.
