"I love it," says Anna, leaning over the railing at the top of the stairs.

"I am forced to confront the possibility that I inherited my excellent aesthetic taste from my maternal grandmother."

"She not the kind of person you want to have inherited things from?"

"She was an emotionally neglectful drunk."

"With a really pretty house. Maybe the ancestor with good taste was farther up the chain?"

"Entirely plausible," she says, relieved. "Or maybe it was grandfather."

"Could be!"

"So there's that. Anyway, pretty guest rooms."

"They're very pretty. C'mon, Cass."

The two of them wander in and out of some guest rooms. They eventually settle on a pair with a connecting door that are right near the top of the stairs and also near a window with a lovely view.

Emily vaguely supervises until they're reasonably settled in.

How reasonable of her!

Anna and Cass decide to hang out in their rooms for a bit, where 'hang out' translates to 'snuggle while Anna pulls out her flowers and puts them back in again a bunch of times'. Just the ones that don't lead to bleeding; she doesn't want to make a mess in this lovely guest room. Cass practices conjuration and makes cute new outfits for them both.

Yep, that sounds like something she in no way needs to supervise. She goes back downstairs, trailing flower petals that should last for days behind her.

They emerge a few hours later, wearing their cute new outfits. Anna goes looking for books and Cass goes looking for Emily.

Well, the flower petals might help with that.

They're a pretty big hint, yeah.

And where will she find Emily?

In a room a floor down floating and concentrating on conjuring things.

"Hey, let's be magic nerds," she says by way of greeting.

"I like this plan!"

"Whatcha working on?"

"Duration extension and trying to permanentify stuff."

"Cool. What's the longest you've got one going so far?"

"Just a few days, haven't been able to get past that..."

"Me neither, actually, I think the longest I ever got something to last was a week, these days if I need something to last a week I just make it permanent."

"Makes sense. Haven't cracked permanency, though."

"Permanency's tough!"
