Marshall's agency is consistently high — he chooses to stay on the plane, chooses to fight, chooses to refuse negotiation. His control collapses when the hijackers gain ground, but agency holds because every setback is met with a decision, not passivity. The deepest gap comes at beat 27: Marshall capitulates and orders Radek released — his control hits zero but his agency is still moderate because even surrender is a choice to protect his family. The only true agency collapse is when Gibbs reveals as the mole — for one beat, Marshall is genuinely blindsided and reactive.
