It wants her name, her mothers' names, her city of birth, her profession, the amount she wants to deposit initially, her consent to fractional reserve banking, a list of any other institutions she's banking with or has credit with, whether she wants a safe deposit box, whether she has ever been accused of fraud or counterfeiting, and whether she wants a pure savings account at a small routine fee or a no-fee interest bearing account according to which her funds may be invested in diverse low-risk ventures and not always available in full on demand.

Annnd she will mark "N/A" on 'mother's names' and "Alternia" as her home city, blahdibla yes consent to FRB, presently no other institutions she's banking with 'that I expect to be available for contact short of a miracle occurring'...

Does she want a safe deposit box?  ...She might, actually.  She could store certain valuable items in it...

No accusations of fraud, yes interest-bearing account...She'll deposit a small-but-noticeable amount.

Oh, and her profession - Engineer will have to do, she supposes.

When she gets back to the teller's window the teller looks at this and says: "...I've never heard of Alternia, which would be one thing, except you also are claiming you don't have moms? I am not allowed to open a bank account for you if you descended entire from the suns above." She hands back the form.

"No, I'm claiming that there's nowhere on this plane you'll find them, and unfortunately that's the honest truth of it.  If you'd prefer I tell you my mother's name anyway, I can, but it seemed...disingenuous."

"I need all four of them."

"...sorry, come again?  Where'd the four come from?"

"...four mothers. If you need to get an account with only two listed that's possible but there's a longer form."

"Oh, my bad, there was a translation issue.  If 'mother' doesn't uniquely indicate the birth-giving parent, at least."

Notwithstanding that her parents definitely aren't multiplexed.

"Yours and your cohabitor's."

"...Yes, I gathered that from context.  Would it matter if they happen to be the same people on both sides."

"I can get you the longer form."

"...I suppose it makes sense."

"...do you want the longer form or are you realizing you cannot defraud a bank into accepting you as a client without a verifiable identity?"

"The longer form, not that it's going to actually solve my not having been born within your light cone problems."  She sounds rather frustrated.

The bank teller gives her a look but hands her the longer form.

What's this one want, then?

Same stuff as the previous form and also cohabitor's name, childhood dreamward, date of cohabitation, and a reference.

"Never a dull moment, trying to fit into a bureaucracy that doesn't have any fucking context for black swan events..."

There is a scribble of several aborted options including 'myself' before 'Ophelia Mondegreen' in the cohabitor slot, 'I'd tell you the truth but you wouldn't believe me; just pretend it's far enough away that there's no hope of finding it' for childhood dreamward, 'Fuck if I know for sure but plausibly not before I was a teenager - and what's the local time zeroed at, anyway?' on date of cohabitation, and..."I should probably ask Wheat about putting his name down, shouldn't I.  Fucking hell, here we go round the mulberry bush yet again.

"As if this is even going to go through to begin with, given my overwhelming generalized weirdness by local standards."

"...Am I correct in assuming that my continuing to be an outside context problem poses at-this-time-irreconcilable issues in my attempt to bank."

"...yes, we need to know who you are."

"Well, the problem with knowing who I am is that my birth certificate is zornwards from here instead of any of the normal directions, so at some point someone's going to have to take my word for it that I'm both sane and telling the truth when I answer demographic questions with 'you literally wouldn't find a record of my birth if you searched the entire infinite plane'.  Do you want to see some extrauniversal math aides to back that up?"

"No, ma'am. I can't get you a bank account if we can't verify your identity."

"...This is going to end in abject bureaucratic suffering.  Who would have the authority to declare that yes, I exist."

"Not me but my colleague is authorized to accept a letter of introduction from a foreign government if for some reason your birth has been irretrievably obscured."

"I arrived here with the clothes on my back and no idea I was emigrating, unfortunately, but that's a start."

"How unfortunate. There is a line behind you."
