I am also thinking the same thing as well too, Ken. I’m hoping that she doesn’t have something similar to the Basilisk hiding somewhere in the library. Either way, I’m hoping to figure out what these symbols are trying to tell us something soon.

(Harry is also jotting down notes about the symbols and what they might be about on a notepad, hoping to piece them together about the library’s secrets.)

By the way, do you have some theories as to why she’s trying to hide whatever is living in the library?
