Link looks at her concernedly as he touches his Sheikah Slate to the shrine pedestal.

"I'm... thinking about a friend of mine, who lived in Kakariko Village. I don't know if... well. We'll find out when we get there."

Well, maybe they can ask if they... sell horses?

The place is clearly horse themed, by the decor and the animals (though it's not only horses, there are cuckoos and a cow out back too). It's unclear what their specific business is.

Oh no, they're going to have to ask. Questions. Of perfectly ordinary people. They're going to have to have informal, non-pre-planned interactions with strangers. The worst.

No. She will be strong. If she must ask after horse purchasing opportunities to save the world, then she will ask after horse purchasing opportunities.

"...hang on," she says slowly, as she begins to envision this interaction. "Do we have... anything... to trade... for a horse...? I guess I can just pull sixty bundles of mushrooms out of my pocket. Or however much it takes."

"I can make elixirs," he proposes. "We want some anyway."

Those cooking pots look public. Hopefully no one objects to them stewing monster parts in them.

...On second thought, maybe Zelda should copy a cooking pot as well.

"Oh, good idea."

She follows him to a cooking pot, and follows his speculative glance to the cooking pot, and correctly guesses that he wants her to copy one, and just touching it isn't enough for her to become able to copy it but when she puts in the effort to actually hoist the big clunky thing a little then she can stick her hand in her roomiest pocket and feel it there. She nods confirmation. Probably best not to haul an entire extra cooking pot out of her pocket in full view of everyone.

Link claims a burnt-out fire whose pot has been removed and starts adding wood to it.

When no pot is forthcoming, the problem occurs to him and he looks around. Is there a latrine somewhere?

Totally! Does Zelda want to come out of a latrine holding a cooking pot?

...arguably less likely to be noticed, but so much weirder if she is in fact noticed.

...how about she comes out from behind the latrine holding the cooking pot.

Acceptable! A kid catches sight of her doing that and looks confused, but scampers off saying nothing of it.

Link has a fire going and is snapping the necks of a few lizards when she comes back.

He offers her one to try duplicate.

She's pretty sure the dead lizard will duplicate just fine, and it turns out she is correct! Link can have as many fresh lizards as he would like.

He'll brew up a nasty-smelling concoction with the lizards, some throbbing purple guts unwrapped from a parcel of leaves, and a few curved fangs. Stones to grind up the parts, then a long boiling at low heat to make sure the essence is extracted, and he doesn't have a proper strainer, so he asks Zelda to duplicate some old netting to filter out the remaining solids. More boiling at high heat to clarify and improve the binding, then...

He didn't think this far ahead. Perhaps more accurately, he didn't remember this far ahead.

"I need bottles and oil," he tells Zelda. "The merchant might have some."

He takes the pot off the heat.

(Zelda, of course, grabs all the bits she hasn't already pocketed before they go in the pot.)

"...hm," she says. "All right, let me see."

She ventures merchantward.

He moves the pot in a safe place, covers it with his shield, and follows.

The man next to the stocked-up wagon is funnily dressed, in mismatching but nonetheless vibrant colors. He's just done speaking to a man out the front of the building when they get to him. He surveys the two approaching with intent, apparently deems them worth his notice, and sketches a bow as they come near.

"What can I help you two with, young man, young woman?"

"Oil of vitriol, vegetable oils, half-ounce glass bottles," Link offers.

"...Budding potioners, I see! 'Oil of vitriol'. I have palm oil, but not the acid. No bottles either. Now, if you want fresh produce goods, I'm your man. Beedle, there inside, he might have the bottles you're looking for. Acid, I don't know where you'd find acid, out in these parts."

"Produce goods?" she says interestedly, thinking of time spent on the road with many more ingredients ready to pull out of her pockets at a moment's notice. "...well, we should focus on our potioneering first." Because until they are done potioneering they won't have any money to spend on produce goods. And she would rather buy at least something if she's going to be pirating this poor fellow's entire stock.

The man fishes out a jar of oil, slightly cloudy. "Fifteen rupees a jar, forty for three. That's market rate—not going to get better than that."

She reaches into her pockets. "Are you interested in buying foraged mushrooms?" she asks, pulling out a bundle. "We've got plenty."

The merchant squints.

"Those are... rushrooms, stamella, yes, but an interesting cultivar you have there. A bit similar to what you see down by Tanagar. I'll take it."

He counts on his fingers, muttering.

"120 rupees for the lot," he declares. "How much oil do you want?"

And then he's rifling in the pouch on his waist.

She glances at Link, who knows better than she does how much oil they should buy.
