Unlike Cate, Keiko doesn't appear particularly taken aback by the situation at the onset of Monarch Episode 10. She inquires whether Bill Randa or Shaw is with her, but Cate is too engulfed in desperation to respond. Hiroshi confides in Kentaro that he vanished to vindicate his parents; he felt compelled to demonstrate to Monarch that the rifts not only exist but are also interconnected. That, he believes, is the sole means to ensure the survival of the human race. Thus, he implores Kentaro to join forces with him, a suggestion that does not sit well with the young boy.
Why did Keiko craft a signal? Keiko fashioned a signal in hopes of being discovered. She remains composed, confident that Cate and a rescue team are en route to her aid, though that's far from the reality. As her suspicions about Kate mount, May and Shaw materialize. Initially, Shaw is reluctant to reveal himself, opting to explain the situation from behind a tree. Keiko breaks down in tears upon realizing she's been stranded for countless decades. The silver lining is that she discovers Cate is her granddaughter and that Hiroshi is safe and sound.
Tim, now back on the job, is eager to delve deeper into the signal's origins. Despite its potential to signify someone's survival, Verdugo asserts that Monarch has more pressing concerns at present. This sparks Tim's fury, who contends that the trio could save billions of lives. If they sit idle, then Shaw's scathing critique of the organization would ring true.
Keiko had recalibrated the radiation emitter to emit a pulse, alerting Monarch to her whereabouts. As Shaw examines the device, she queries Cate about Hiroshi. Even after all that has transpired, she paints a cheerful and hopeful portrait of her father.
What is Shaw's scheme? Shaw devises a plan to extricate them from their predicament, but it necessitates Keiko reverting the machine to its original setup. They affix branches to it and commence transporting it elsewhere.
Tim locates Kentaro at a bar and elucidates the significance of the signal. The prospect of Cate being alive fills him with joy, and he reveals he knows someone who can assist them. Hiroshi, tears streaming down his face as he watches Bill Randa's video on Skull Island, is startled by a sudden knock at his door. Tim and Kentaro enlist his help, suggesting there might be a way to rescue Cate. Hiroshi concurs but cautions that Monarch won't be of any assistance. Fortunately, Tim harbors another plan.
Shaw escorts them to the vessel he employed to reach Axis Mundi during his mission. They hook up the emitter to it, intending to lure a Titan that will facilitate their journey back to their side of Earth. However, the creature that arrives is a belligerent pterodactyl, already lurking in the vicinity. It wreaks havoc on the ship, leaving them in a precarious situation.
Shaw dashes out to make the necessary repairs, ensuring they can depart the perilous zone unscathed. Almost immediately thereafter, Godzilla emerges from the rift with a thunderous roar, engaging in a fierce duel with the pterodactyl. The colossal green lizard effortlessly dominates its aerial adversary, paving the way for the protagonists to initiate the ship's engines. Shaw, with all his might, strives to board the vessel, but fate has other plans—he finds himself unable to make it aboard. Keiko clutches his hand tightly, a poignant echo of a previous moment, but true to his heroic nature, Shaw makes the ultimate sacrifice, allowing the rest to flee to safety. As he tumbles away, the ship's hatch seals shut, and they soar through the portal, leaving chaos behind.
They emerge into a sophisticated facility where Kentaro and Hiroshi stand eagerly, awaiting their arrival. The atmosphere brims with joy and relief, but the reunion is abruptly interrupted by Brenda from Apex, who insists that everyone must proceed to medical evaluation and debriefing without delay. May and Cate are taken aback, their expressions a mix of surprise and concern. Kentaro, with a wistful smile, remarks that much has transpired over the past two years. Just as the facility's gate swings shut, sealing them off from the outside world, the mighty roar of King Kong reverberates beyond the walls, a reminder of the wild and untamed forces that still lurk in the shadows.
