Crockett and Tubbs are experienced operatives — their agency stays high throughout because they are always making tactical choices, even when the situation deteriorates. Control fluctuates wildly with the undercover operation's stability: rising as they earn cartel trust, crashing when Trudy is kidnapped. The gap is tightest during Acts II-III when professional competence translates directly into operational control, and widest in Act IV when agency (they're still making sharp tactical decisions) diverges from control (the operation is falling apart around them). The ending settles both lines below the opening — Montoya is untouched, but they chose every step.
