When she speaks in ｃｈａｔ ｆｏｎｔ , that means she doesn't show up in person because she is a Curator- which is quite alike a Narrator. She can connect herself to other Offices to manipulate with stuff inside them; but that would require some efforts + hacking and it's for a very short time, so she doesn't do that often. Some beings can sense her being all around even as she is not literally- ...but she is kinda all around. Unlike Narrator, she is capable of going from a place to place. When that happens I write her speaking just like anyone else, quote marks included. She is nearly omnipotent as long as she stays in her own place; which is a set of giant underground buildings. The local Office is nothing but one of many Test Chambers that "got a little out of the hand" for her.
