Chapter 3: West Wall (IV)

You decided to go to the West Wall. Like the East Wall, there wasn't any decorations or wallpaper. There does seem to be some discoloration on the white wall, but they don't look like anything helpful and could just be a red herring at best.

The sink was round with two pipes attached to the bottom of the sink, one flowing water in and out of the faucet while the other draining water out of the sink, and conjoining into a single pipe through the floor.

There were signs of deterioration and rust along the metal parts of the sink. The mirror was rectangular in shape and protruded a bit outwards. The reflection was a bit blurry and dusty as if someone forgot to clean it.

The strangest thing was that occasionally, fog seemed to appear on the mirror, but only briefly though as it quickly disappeared. If you didn't pay close attention to it, you might not even notice this peculiarity.

What should you do next?
