...First major question will be even getting to the Ice Court. Anyone entering through the harbor at Djerholm will be under tight watch. 

So they don't go through the harbor. They're on a ship, ship has landing boats, Fjerda has a lot of coastline.

Not a lot of harbors, though. There's a large stretch of cliffs north of Djerholm, then a narrow stretch of shallow natural harbors, then the ice this time of year. And you can't go very far south of Djerholm without hitting Ravka - the border is in reach of deployments from Djerholm, so that coastline is watched. 

It is possible to make it overland.

"Did your planning include cold weather gear and snow goggles?" she asks Kaz.

"Coats, boots, leggings, yes- Inej, did you end up finding any goggles?"

"I found three, so not enough for everyone. And I'm not sure how good they are."

She mutters something that might be 'this is going to suck.'

"More likely to work than getting everything through customs."

"Even so... We'll have to ditch everything we're unwilling to lose at the prison gates."

"That will be necessary regardless."

"And there might be preparation we can do in Djerholm..."

"What do the roads into the city from the land side look like?"

She describes them - they mostly won't be going over roads if they're coming in through the north, rather cutting through the bush with Susanne as their guide, but there's good roads once they get closer to Djerholm...

Yeah, overland to roads, then they can enter the city with less suspicion.

They can't all pretend to be Fjerdan... But Susanne is, and Nina can - and 'act as a tour guide for tourists' isn't an odd way for two teenagers to be making a bit of money. 

Yeah, she can do that.

They'll have to pretend to be young widows for it to be seemly, though two teenaged sisters in a big city might do work like that anyways. Or one of them is Tailored to look male and they pretend to be married. 

Shouldn't be too hard to get a story straight.

They might be a little bad at pretending to be sisters. 

Susanne might be bad at pretending, Nina is a great actor, thank you very much.

Is that a challenge? 

If that'll inspire her to be better at it, sure.

And she doesn't exactly object to being also sisters. 

Kinky.
