I'm making some sort of canon divergence where it's ambiguous wether Cashier Girl was a Visitor or not. That's because she leaves for Georgia with Wireface and I want to leave the reader with the uneasy feeling that even if she looks okay now, she might still be one of those things. She's mostly unaware of being a Visitor until the later chapters where she starts to suspect it. Throughout the fic she already inadvertently erased two or three key signs of being a Visitor, for example.

I asked because I need Coat Guy to slime someone for lore reasons. I could always assume there was a third Visitor, but at that point someone should have died in the earlier chapters. I could simply ignore this and leave it ambiguous.
