I'm gonna suggest you stay in the hotel. I usually don't have my phone out when I'm playing missing person, but I'll bring it this time in case you need me for something - She writes down the numbers, demonstrates how to call the phone from the hotel landline.

She is dutifully attentive.

And Bella goes off to attempt to extract wish potential from a sixteen-year-old one way or another.

Hotel rooms are so ugly. She kind of wants to cry but that won't help so she closes her eyes and sings.

Bella is back in three hours. Hi.

There are flowers scattered across the hotel room carpet and growing in bunches from the headboards of the beds. She opens her eyes and stops singing. Hi.

Where did all these flowers come from.

Oh! Sorry, I must have sang them, I was feeling lonely. I can clear them all up. How did it go?

I told her you're straight in a way that made it clear that I'm not, we talked about wishes for a bit and I hinted that there was something I could have done with mine and didn't get the chance to because I wished under time pressure without knowing enough, she kissed me, I'm going back tomorrow.

She expected that to bother her but it bothers her differently than she expected. Okay. That's...good?

Well, it's not instant success but it's promising. And she's been warned now that the fluffs aren't perfectly trustworthy, although I didn't go into the whole they're-so-evil spiel.

Does she know that if she gets too sad she'll turn into a witch?

Yeah, I mentioned that part. She can only witch after she turns into a puella magi, though, it doesn't happen before that.

And she still thinks she might want to do it?

Yeah. If she ages out of potential and isn't a magical girl at the time, she's vulnerable to witch miasma. And she gets a wish out of it, which I have explained are a pretty high-potential thing handled right.

Right, makes sense. 

I think the likeliest failure mode at this point is that she freaks out when she finds out this is a time loop and I don't want her along in it. I might have to tell her I'll come back for her next time but that you've only got the one shot, or something.

You can say that this way, she gets a wish every single time loop until she wishes herself into it, so everyone else only gets one wish but she can get several.

Yeah, but she won't remember them. And I don't think I can push the 'for science' angle either.

'You can try different wishes and I can tell you how they work out and then you'll get to make a way more informed decision than anyone else does'?

That's good. Bella writes it down.

I really hope this works.

Me too.

She starts gathering her flowers. Where should I put them?

Uh, maybe leave them in a heap on the balcony or something, they won't attract much attention there.
