#1590: The Source explain

[Cueball is standing in an empty room looking in the direction of the next frame.]

[Cueball turns his head and looks the other way.]

[Three smaller panels with the same total height as the first two frames follows. In the first frame Cueball walks on a grey surface.]

[In the next Cueball is standing between two doors, looking over his shoulder towards the one to the left, but choosing the one to the right behind which a stair is. He is waking towards this door with his hand out towards the knob.]

[In the last of these smaller panels Cueball has just walked down to the bottom of the stairs.]

[Cueball walks towards a machine that is standing near a wall connected to a socket in the wall. On the machine it says:]

High pitched hum generator

[Cueball kneels behind the machine and unplugs it from the socket in the wall.]

[Cueball walks away from the machine, the plug now lying on the floor between the wall and the machine.]
