C0m3 and Pl@y

You get up from your desk chair, and enter the darkness, walking towards the noise. Then, the light from the lamp on your desk goes out and the rest of the room goes completely dark. You walk a few more steps forwards, and stumble upon a metallic object. You stoop down to pick up the cylindrical object, and realise that it's a torch. You eventually find the switch, turn on the torch, and scan your surroundings. Ahead of you is a cubical with what looks like another person sitting at it. You think this might be the person that you heard before, then a sliver of fear creeps into your mind. Who was this person? Why was he at your workplace at such an hour? Nobody you worked with said they would stay back with you for extra work.
