The latest episode of Reacher Season 4, Vote For Sampson, delivers the long-awaited answers that have driven the season’s conspiracy while staging one of its most intense set-pieces yet.
After the previous episode left Jack Reacher and Detective Tamara Green in the back of a van facing what looked like certain execution in the woods, this chapter opens with the kind of immediate reversal the series does so well. Springfield, the capable security officer working for Congressman John Sampson, intervenes with lethal efficiency. Springfield has been circling the edges of the story long enough that his arrival to be a surprise but not unexpected. From there the episode starts to role out the answers, finally peeling back the layers around Anna Merrick’s photograph and the USB drive that has cost so many lives.
At the heart of the episode is Reacher’s confrontation with Leo Ahlquist. Ahlquist spills all the details of a secret program known as Operation Mongoose. In the late 1990s, after the Tokyo subway sarin attacks raised alarms about chemical weapons, elements of the U.S. government funded research intended to develop such agents and then create countermeasures. The work took place at a facility in Indonesia. Ahlquist was involved as a young researcher. The photograph Anna carried captured a whiteboard containing the formula. Modern AI tools can now clarify the previously illegible details, making recreation possible. The Hoth sisters have already begun that process, testing a version of the agent with horrifying results and preparing a demonstration tied to both profit and personal vengeance.
These revelations arrive through a lengthy interrogation that includes flashbacks. The information is what we’ve been waiting for but it is a rather large info dump. Reacher breaks fingers and applies pressure in classic style, but the volume of backstory required to connect Indonesia, General Putra, the Hoths, and the current threat slows the momentum that the series usually maintains through physical action and rapid fire discoveries but nce the pieces lock into place, the stakes become concrete and urgent in a way that earlier episodes only hinted at.
Alan Ritchson continues to embody Reacher with the physical presence and quiet intensity the role demands. He is not a man who wastes words, and the performance benefits from that restraint even when the script requires him to extract or process large amounts of exposition. Sydelle Noel’s Tamara Green remains a strong partner, grounded, competent, and unwilling to be sidelined. Their working relationship has developed naturally across the season, and their shared focus here feels authentic. Marc Blucas steps forward more fully as John Sampson. For much of the season the congressman has operated in a grey zone, keeping secrets and issuing ambiguous orders. Episode 7 fills out his story. He reveals that he was the one who pulled the trigger on Putra during a U.S. operation years earlier, and that Amisha witnessed the killing. That personal history explains why his fundraiser becomes the chosen target: a public demonstration of the weapon combined with revenge. Blucas plays the shift effectively, moving from polished politician to a man drawing on old training when the threat materialises in front of him.
Where the episode truly shines is in its finale. Once Reacher and the others realise the fundraiser is the real target, the tension is cranked right up. Reacher races to intervene while Sampson, already on site and now aware of the danger, begins scanning the crowd using the same behavioral markers used in the opening episode to kick this whole adventure off. The identification of Tomas Waberi as the suicide bomber builds steadily. The climax itself is shift. Sampson does not wait for backup or a perfect plan. He acts, tackling the bomber and driving both of them into the Delaware River as the device detonates underwater. Reacher arrives in time to witness the blast but not to prevent it. Sampson’s fate is left unresolved but seems definative, as is the question of whether the underwater detonation fully contained the chemical threat. It is a strong cliffhanger that raises the emotional and practical stakes heading into the finale.
Vote For Sampson is not the fastest moving episode of the season, nor the most elegant in its storytelling mechanics. It carries the structural burden of explaining almost everything before the final confrontation. That burden shows in places. At the same time, it is one of the most consequential episodes so far. It creates a sense of realdanger, gives several characters meaningful agency, and ends on a note of genuine uncertainty and sacrifice. Ritchson remains the gravitational centre, but the supporting performances, particularly Blucas in the closing scenes, rise to meet the material. The chemical-weapon plot raises the scale without abandoning the grounded, street-level investigation that defines the show.
As the story moves into its final chapter, ambiguity dissipated, the villains are clear, and the danger feels real. The combination of hard-won information, personal histories colliding with present danger, and an unresolved act of courage sets you up for what’s to comes next. The episode does what it must to deliver all the important information while still delivering the physical and emotional punch expected from the series.
