Janet's rarely been so grateful for the size of the mansion. She can catch some of the sounds of revelry if she really strains her ears, so she's just... not doing that, focusing instead on reading some stupid magic textbook she got from the library. It's not one whose theory she recognizes, so it's probably from a different world, which is annoying. Someone should organize that mess of a library.¹

Careful not to seem too eager, she counts to five before she opens the door and musters up a half-smile for Susan. "Hey."

¹Someone has tried. Many times.
