What happened between Sator and Kat?

Sator shoots Kat with an inverted bullet, which means radiation poisoning as well as regular bullet damage. To head that off, the Protagonist and Neil take her through the temporal turnstile so she’s also moving backward in time, just like the bullet.

How does the protagonist fight himself in Tenet?

The inverted explosion sends The Protagonist, who is wearing protective gear, directly into a fight with his past self – the same fight we saw him have earlier: he was fighting his future self. Seeing it’s a future version of him, he prevents The Protagonist from shooting himself.

What is the moral of the movie tenet?

Tenet means a principle or a belief, which suggests that the Protagonist has to simply believe in what he is doing, without the full facts. Time inversion is a key theme in this movie, which means time can run backwards.

Why didn’t the algorithm go off when Sator died?

Sator has a dead man’s switch which will detonate the algorithm and reverse entropy, ending the world. Sator’s dead man’s switch by itself will not detonate the algorithm. It just sends out the location of the dead drop (the buried capsule).

What happens if Sator dies?

In short: if Sator dies, his heart-rate monitor will drop to zero, and that will set-off the Algorithm, which will end the entire world. Sator’s planning to commit suicide, which will set off the Algorithm.

Why would the world end Tenet?

What is the Algorithm and how would it end the world? The Algorithm is a piece of technology from the future that can reverse the entropy of the entire planet. If activated, it would cause everything to invert, wiping out the past, time, and everyone who ever existed or will exist.

What happened at the end of Tenet?

As Neil explains, this is the end of the story for him – he has to go back into the inverted side of the battle, so that he can open the gate and step in front of the bullet meant for The Protagonist. Neil’s loop is closed, but for The Protagonist, this is the beginning of their story together.
