[You follow the cable back behind the chairs and into the shadows. It follows the wall to the corner, and there, you find the end of it.]

[Surprisingly(?) there is something plugged into it already -- a red cord. You follow the red cord with your eyes, and you can see it goes up the wall and connects to the spotlight that's lighting the stage.]

[Beside the yellow cable, laying uselessly on the floor, is a black cord that isn't plugged into anything. It looks like someone unplugged it so they could plug in the spotlight, instead.]
