I just came across a lab, and as I was walking through a hallway, I started hearing things about observing human brains and ethics and children. I then discovered that they were coming from a room with a Mi-Go contained, and I was wondering if the sounds were a recording that was on a loop. I killed the Mi-Go, and the “voices” stopped. Did the Mi-Go imitate the last human voices it heard? Creepy, but amazingly cool.
