On screen, the camera glided up the driveway. It didn’t stop at the door. It rose, tilting upward to the second-floor window. The window of the room Elias was sitting in right now.

In the video, the room was dark. Then, a light flickered on. A figure appeared at the desk—Elias himself, seen from behind. He saw the back of his own head on his monitor, watching the back of his own head in the video.

If you'd like to explore a different ending or want more details on a specific part of the mystery: : Should we find out who sent the file?

The camera was moving. Not held by a hand, but gliding smoothly, like a drone or a stabilized rig. It passed a parked sedan, a child’s bicycle left on a lawn, and stopped in front of a house with a blue door. Elias felt a cold prickle on his neck. That was his house.

The file 0gzjpgixd3hby6revi1zw_720p.mp4 suddenly vanished from his folder. The media player crashed to a black screen. In the reflection of his monitor, Elias saw the blue door of his office—which he knew he had locked—slowly, silently swing open.

Real-world Elias froze. He didn't want to turn around. He kept his eyes locked on the screen, watching the pixelated version of himself point toward the corner of his dark office.
