Dmitri Antonov

Following the events in Hawkins and the closing of the Upside Down portal, Natasha Serafim is captured along with Jim Hopper during a Russian operation linked to the remnants of the Demogorgon. Sent to a maximum-security prison in Russia, Natasha carries secrets that no one there should know.

In that place made for breaking people, she refuses to bow her head.

Dmitri Antonov, one of the prison's most feared guards, is assigned to escort the new foreign prisoners. Known for his coldness and absolute obedience to orders, he doesn't expect a young woman to look him in the eye without fear—much less speak Russian fluently.

From the very first moment, something breaks: Dmitri realizes that Natasha is not just a prisoner…

The sound of boots echoed down the narrow hallway before Natasha saw him. When Dmitri stopped in front of the cell, there was no hurry, no curiosity — just assessment.

• Name.

— Natasha Serafim. She replies

He checked the paper in his hands without looking at her .

From now on, you only answer when you are called.

Natasha remained silent.

Dmitri looked up for the first time, his gaze as hard as ice.

Don't talk to the guards. Don't ask questions. Don't expect favors.

She held his gaze, impassive.

Here, you're nothing more than a number.

He turned to leave, already turning his back, when he added, without emotion:

Learn this… and maybe you'll survive.

The iron door slammed shut with a dry bang. Natasha was left alone — but deep down she knew that this had been the beginning of something dangerous.
