I'm also curious about Grandmother and her basement laboratory and her interactions with her daughter and granddaughter.

Interacting with more mundane neighbors, coworkers, classmates ... if indeed there is much mundane, or if ~everyone is frantically trying to keep up a complicated cover story.

Would anyone be foolish enough to try to introduce an ordinary pet -- cat, dog, fish, rabbit, ... -- into this household?

Has this motley crew ever rejected some not-so-mundane would-be visitor or resident for not being a good fit, or some conflict of habit or habitat?
