# Did Neil use an inverted bullet at the opera?

At the opera in Tenet, when Neil saves the protagonist, he shot an inverted bullet. Before you say that he himself was inverted, I would say think again.

The protagonist sees him leaving running down the stairs in a normal movement, if he was inverted, he would be running down backwards, which in his normal time means he is arriving at the scene to shoot the bullet.

If he was actually inverted, then this means in his normal time he was arriving at the seen running up the stairs backwards, which doesn't make sense.

I lean toward that it is a mistake in the movie, just to allow the protagonist to see the red ribbon on his back pack for the final scene, but not 100% sure.

• Neil could have worked in reverse to make himself appear normal. Someone who has a solid understanding of the mechanics of Inversion could in theory, at least in the important moments, run backwards down the stairs, and then backwards up the stairs, so that when the Protagonist sees him, he appears to be moving normally, and then saves him with the inverted bullet.

• Why all the hassle? What for? Why bother covering the inversion of himself if his bullet going to be observed inverted. Also, it is extremely difficult to move backwards where when played in reverse would look normal, specially running up the stairs, if you try to do that the movement would look very weird.

• Maybe he fired the bullet at an earlier time, then unfired the bullet at the right moment? As far as all of the hassle, that was the first time the Protagonist saw inversion. It made it much easier to believe in later on. Instead of trying to convince him of some crazy idea, he was having a bizarre event explained. Neil could have done prep work on the opera in the inverted world, since they have the benefit of future knowledge before the events begin. Dec 22, 2020 at 15:29
• Who says that Neil was inverted there? The bullet obviously was, but you don't need to be inverted yourself to use an inverted bullet (the Protagonist learnt inversion shooting inverted bullets). Neil could be just inverted back to normal. Dec 23, 2020 at 4:25
• But why and how does he know that an inverted bullet is in the stage stair/step, and going in with an empty gun? when the protagonist shot the inverted bullet at the lab, the female scientist already knew there are inverted ones in the wall, that's why she asked him to pull the trigger.
