At this moment, you don't understand what the circles mean. And also don't necessarily notice it because your face is all scrunched up trying to smell as little of Joanne's rotting corpse as you can. You get fed up with Joannes terrible smells and take her outside and throw her down a manhole. Only to realise that when you got back, there was a shadowy figure walking around the halls. You say to yourself, "uM, I THINK THE FUCK NOT" and proceed to get the salt, create some holy water and go into the halls to hunt it down. Only to realise once again, THE FUCKING THING CAN TELEPORT.
