"Literally just that weird parasitic egg demon that I mentioned. But it doesn't explain the gym teacher's actions unless the eggs also secrete some weird thing that does that. The book, however, didn't mention this."

"Yeah," she sighs. "We might have to go pay the morgue a visit anyway."

He nods. "Are we gonna do that first, then, with the spell?"

"It's... probably best if we wait until the evening, but yes."

He nods. "Makes sense."

The spell being all done and ready, she returns to her living room, where Willow has abandoned all pretense of actually looking through demonology books, and sighs. "So, uh, how about we catch something to eat and then go look at a dead body?"

"Sounds like fun," says Theo, getting out his phone to send a quick text to his dad. "Any good food places around?"

"Ooh, there's a sushi place I really like a couple of blocks from here," Willow says, raising her head from the book.

"Uh, okay," says Theo.

Sure, sushi, why not.

"You all have your stakes?"

"Yeah."

"Yep."

"Then off we go."

Off they go! The sushi place isn't very far.

Woo, sushi place.

And after that: morgue!

When it's dark. And the morgue's closed. Sadde whispers a word into the lock, and it opens.

Theo follows her in!

Yay, morgue.

Sneaky sneaky to the place where the horribly mangled body is...

Then she gets the herbs she did not burn earlier and whispers another word in Latin. They're consumed by invisible flames, and the smoke and ashes start coursing through the librarian's body.

Wonderful.

"Okay, I got it."

"What did you find? Just a magical signature thing, or some stuff about the demon?"

"Magical signature thing," she sighs. "Nothing special about it."

"… Nothing special other than, uh, being a magical signature, right? So it still lets us positively identify the demon, right?"

"Right! And then we'll see if the gym teacher has the same magical signature and..." Pause. "I didn't actually plan that far ahead."

"Then we brutalize him because he's already lost to the demon and we're savages? Oh, wait, we don't know the demon works that way."
