Bella goes up and sits in her room.
She has five hexes.
Five.
That's rather a lot of hexes.
She gets out her notebook, with the lists, and she makes some wishes.
And then she goes to bed, grinning.
In the morning it will be time to make plans.
The takeaway from this seems to be: don't talk in front of Bella's friends. Well, whatever. He does not have strong feelings one way or another about that, so he may as well not.
"It would probably be weird if you were around them for long and didn't talk at all," Bella says. Angela can be heard getting in her car and driving away, which is Bella's cue to get rid of the illusory casts. "But if you don't actually care either way, it might be simplest not do it a whole lot. I'm running a lot of social algorithms that would be complicated to document and explain and translate so they'd work for you instead of me."
Predictably, there are no good associations in his head for following rules.
She collects the lair notebook and relocates to the kitchen table.
"So this is the basic shape of the thing. Color scheme? Flooring? Lighting?"
He has a vague notion that bright colours might be fun, and another vague notion that he might get sick of them after a while, or at least sick of the same ones in the same places all the time. Lighting he just hasn't considered in enough depth to have any opinions at all.
This is fun. She's humming.
"You forget," Alice says cheerfully, "I get off on scrubbing things. But eh, I can clean my bathtub once in a while for kicks."
Bella nods. "Okay. Hm." She looks around the room for more inspiration. And adds a little arrow pointing at the word "carpet" indicating that there will need to be a nice padding layer between the carpet and the rock underneath, to make it comfy to walk on. (She does plan to visit this place, after all.) "I think this is probably it, except for your furniture that doesn't need magic electricity and water. Where do you want to put the entrance? We can check out the composition of the underground under your first choice first."
"Somewhere near here," he says. "Like, off in the woods somewhere or something, towards the school?"
"There's a big rock roughly thataway," Bella says, gesturing. "Big enough to walk into and not immediately fall down the stairs. By accident."
She goes up to where her computer is located in her room.
Bella does some cursory searching, and says, "Looks like we're good. We only live under permanent water, not above it. Wanna go install the lair now?"
"Sure, why the fuck not?"
"Righto." Bella turns invisible. "Don't want the neighbors to wonder how I'm, you know, walking. Also, this way I can fly there." Alice can hear her go down the stairs.
"Cool," he says cheerfully, meaning both okay and awesome. He trots down the stairs after her.
Partway down the stairs, Bella remembers flying. She's not used to having it yet. Off the stairs and into the air she goes. She puts on her coat; it disappears from sight as soon as she picks it up.
"Kinda weird," Alice comments, and then observes that he should probably get in the habit of not talking out loud to the invisible woman before they exit the house.
Bella flies out the door and up, up, up into the air. She can "hear" Alice from any distance; if she needs to talk to him to direct him towards the rock, she can always dip low.
Wheeeeeeee!
That makes him vaguely pleased, too.
(He wonders idly about hexing himself invisibility powers that make them both able to see each other when they are respectively invisible, and thinks happily of going flying with her, and entertains a brief and completely unrepentant daydream about invisible midair sex.)
"Bear left a bit," she says.
When he feels the sense of being read depart, he cracks up; when she directs him leftward, he obeys.
