Speaking of which, I've only watched this movie once, it's new, so I'll write it down quickly. In fact, this person is a follower of "Inception". I will explain the following content to you.
The train scene we see at the beginning of the film, we generally think of it as the real world. In this world X is a captain in Afghanistan who saved people from dying. Everyone understands in the first part of the movie, everyone thinks that finding the suspect is the climax of the movie, it is far from the case, which makes a lot of people who didn't understand it in the last 20 minutes hurt their brains, and everything is in the last 20 minutes. In minutes, the effect achieved by the entire movie "Inception" was achieved. So let's look at what happened in the last 20 minutes. First of all, X asks G's help to give him another 8 minutes to enter the source code world, complete the call to his father and his wish to confess to a woman, and ends his life after 8 minutes.
In these 8 minutes, X came to the source code world again. He did three things before pressing the red button in the real world G: 1. He arrested the suspect. 2. Send an SMS to G'. 3. Make a phone call to my father and be with a loved one. In this source code world, the train was not blown up in the end, but in the real world, the car crashed. When the red button was pressed, the picture on the train was frozen. We set this moment as t. At time t, G' received a text message, and just as she walked to T''s office, he and she learned that the suspect was caught on the train (this is the same as the original suspect who was caught on the road) is not the same), so we know that we have entered the next source code world, that is, if the real world is set to the Nth layer source code world (N is a natural number, N=0, which is the real world), then X In order to find out that the scene where the suspect has returned countless times is the Nth layer, (where each time he travels back several times is a new layer of source code world) the one that was successfully blocked is (N+M), and sent a text message to G', indicating that the world where G' receives the short message is the (N+M)th layer. And the consciousness of the X that G' wants to help is in the real world (layer N). But obviously she couldn't help him because they belonged to different layers. X consciousness has always existed, the thickest red line.
When the (N+M) floor is pressed, the world continues, and we can see that the history teacher and his girlfriend survived on this floor. And this person is not X, he just borrowed the body of the history teacher to complete the mission. So we can naturally infer that X used the body of Captain Kurt Stevens to save people before the explosion. (This also explains why it says "Captain is very good at saving people"), which shows that since the invention of source code technology, there are infinite layers of source code worlds extending, but we only see one of them. It is G and T who really know X's identity.
Many people may not understand why X would have a lot of hallucinations every time he went back to find the suspect (girls, mirror sculptures and other scenes where the history teacher and his girlfriend dated later), it's like this, I think these hallucinations are actually in the history teacher's brain Imaging, and X has to experience a period of flashbacks in order to use the body of the dead teacher and the identity of the living teacher to save people.
Last but not least, that red button is, as I deduce, not the kill button, but the amnestics.
Personal opinion, only represents my own point of view, not necessarily the same as yours, but welcome to participate in the discussion. There are definitely some flaws, and I hope the majority of comrades will criticize and correct them. (The blue font is the opinion of classmate Zhao that I agree with. As my supplement, I am very grateful)
