brainstorming exercise: you are Mabel, you have just read Flatland, you have been given reason to believe this book describes Bill Cipher's homeworld, and you have Bill at your mercy for crayon time. What follow-up questions do you ask him.

I need her to grill the hell outta him, but only a couple questions are important to the ongoing plot, so most of the conversation will just be For Fun. In light of this, might as well chuck in some questions that actual readers are interested in.
