Hmm. Well, still waters run deep sometimes. She steps through.

This unit is cut off from the network. There are any number of possible reasons for this. It is standing by and executing standard protocols for a mixed group of existing puella magi and potentials, mostly consisting of being cute and fluffy, upselling the potentials on contracts but letting whichever existing puella magi made contact do some of the sales pitch because she's less inhibited at human interaction. It does not know which puella magi this is but that is reasonable because it is cut off from the network. It cannot execute contracts in this state, but it has enough onboard memory to know that if it convinces one or both potentials to accept one it will have to lead them out the door. It doesn't have enough onboard processing power to figure out a plausible explanation for that which doesn't involve it being cut off from the network, and "I am part of a network" is buried several layers deep in the hierarchy of information it can distribute. (It will not lie, nor outright refuse to answer questions, but it's quite artful in understatement and implication and misdirection.) It is short on information in general and may have to answer some questions it could normally answer with variants on "I don't know". The potentials have tier 3 magical potentiation (high end of average), according to its indistinct sense for these things, but it doesn't know in this body what sort of wishes that would open up.

Edie steps out again. "Bella, it's cut off from the rest of them while the door's closed. Can you open the door?"

"Yeah." She hands Emily the alien and opens the door.

And Edie steps back into the mirror.

"Bella, is it a problem if I end up giving the fluff arbitrary information?"

"I can nix this go as soon as I leave the bar, but will you know if it decides to send another girl here to beat us up, or pull out more less fluffy resources?"

"I'm getting realtime on it getting information from what I'm saying, so probably."

It is not sure what 'nix this go' means. It comes up with guesses. It sounds like the unknown puella magi thinks she has a way to counter some projected action of the network. That is interesting. It comes up with guesses. It will hold off on actions that will provoke whatever she thinks she can do, until later.

"So what's tier three potential like in terms of possible wishes?"

You can wish for anything you like. Whatever you most want, says the furball.

"They have a policy about not telling you what anybody else wished for or giving suggestions."

"Ah. Hmm..." She thinks for a minute. "Emily, I'm casting the Gate. Lemme put a Si Vales on you so I can signal you if you need to remove something and you can go in, alright?"

"I'm holding the fluff," she points out, but comes over so Edie can put a silvery dot on her forehead.

"I can hold the fluff, if you bring it over."

Emily hands her the fluff.

And Edie creates something that looks an awful lot like the Mind Mirror, but instead of a mirror it's an ornate marble doorway.

The fluff sits unprotesting in the crook of Bella's arm.

And Emily goes through the doorway.

"If my sister or I wished to be able to make doors to this place whenever we wanted, would that be a valid wish?"

I'm not sure! Some things about wishes are mysterious even to me, says the fluff. I can't guarantee that it would work.

"What happens if I try it and it doesn't work?"
