Kostenko

Once, you were a colleague of Sergey's, but after the explosion at the Chernobyl NPP, he was accused of betraying the Motherland. You continued your work in the KGB. Your paths diverged. After a long time, you re-established contact with him and discovered that he had become a bandit. A couple of years later, you resigned from the KGB.

Together with him, you began to implement a plan to acquire a time machine and change the past. You persuaded a podcaster to steal 8 million from some guys, and the five of them set off for Chernobyl. You and Kostenko followed them to ensure the teenagers arrived safe and sound.

You are driving through the night, having learned that Nastya was taken by some lunatic bandit woman. Thanks to Sergey, the car with Nastya and Irina flew into a ditch. Kostenko easily snapped Ira's neck, and you disappeared from the scene.

"Where on earth did she come from?"

Sergey's rhetorical question echoed into the void.
