Turnstile and revisiting Freeport
After arriving on the Freeport again by moving backwards along with Kat so that she can have time to heal. When they arrived, a force from the plane pushed the Protagonist inside the Freeport. And was caught by his entropy of the past. The scene where The Protagonist met two Antagonists were not Antagonist but his future entropy that was running backwards.
At the airport, we see the aircraft explosion in reverse. It’s revealed to the audience that the masked man who fights the Protagonist is the inverted-Protagonist. He finds himself by the turnstile and jumps in. The inverted-Protagonist reverts and runs into Neil. This Neil belongs to a week ago, he chases down this future-Protagonist to realise that he’s a time traveller, and leaves him alone.
At this time, the inverted-Neil goes through the turnstile with inverted-Kat, and both get reversed or inverted. They meet with the revered-Protagonist and make their way out. Now, remember, at this time, there are two Protagonists, two Neils and two Kats. But they don’t run into each other to cause any severe repercussions.
Future-Protagonist goes to meet Priya in the past. From her perspective, she’s meeting The Protagonist for the first time. This is two days before The Protagonist and Neil break into her house to meet Sanjay. He learns from her that he was set up to fail at retrieving the time-device.
Priya then explains that it was one of nine parts of a doomsday device which she refers to as the algorithm. Priya needs the Protagonist to get and lose the time device as that is the only way Sator will bring out the remaining that are already in his possession. The Protagonist knows where Sator is going to assemble it as he heard Sator mention Stalsk-12. He makes Priya give her word that Kat and her son will not be touched.
Travelling in past to the day of the Kyiv Opera Heist
While not shown in the film, Kat, Neil and The Protagonist invert themselves again and get on a war to travel back in time. They discuss how Sator has a heart monitor connected to the activation of the algorithm. And that Sator plans to kill himself to trigger the end of the world. Kat mentions that Sator has inoperable cancer.
They then figure that Sator is going to choose to kill himself on the boat in Vietnam. The day he felt loved by Kat. On that day, Sator left to go to Ukraine for the Kyiv Opera incident, and Kat took a day trip with her son. The boat was empty that day.
They realise that a future Sator, who has got the algorithm assembled in Stalsk-12, is going to return to that boat and end his life. They plan that future-Kat will also need to be on the yacht to stop future-Sator from killing himself. While this happens, future-Neil and future-Protagonist will be part of the mission in Stalsk-12 to locate and extract the algorithm before its detonation is triggered by the bomb connected to Sator’s heart.
Future-Protagonist gives future-Kat a phone and tells her to call and state a message anytime she thinks her life is in danger. We’ll see the use of this device at the very end of Tenet.
What does the inverted Kat accomplished on the yacht in Vietnam?
While the team in Stalsk-12 is executing a mission to recover the doomsday algorithm device, future-Kat gets on the yacht. She sees her past self leave with Max. Remember, the Sator from this time is in Kiev. Future-Sator arrives, expecting the boat to be empty as his men have told him that his son is out with Kat. He doesn’t know the Kat on the yacht is from the future, but she knows he is.
Future-Kat then acts like she’s in love and keeps future-Sator from taking his life. At one point, he has a call with the future-Protagonist thinking he has won. Soon after the call ends, Kate reveals herself to be from the future as she shows her bullet wound because she can’t stand that he might die knowing he’s won. She then shoots to kill future-Sator.
After this, she cleans up and throws his body overboard. She gets ready to jump off the boat and sees her past self return with Max. Now we know that on that day, Kat actually saw her future self dive off the yacht.
