"Here's hoping."

She likes nuts, it turns out.

She can buy more of them if she likes them! (Tanya thinks harvesting wild nuts and fruit is a bad idea; unfamiliar kinds of nuts might be poisonous.)

"Reminder that Detect Poison."

"Does it work on anything that's bad for you to eat, even if all it does is cause diarrhea the next day? ...are exactly the same foods bad for drow and humans and other kinds of people or are there variants of the spell?"

"I don't think there's variants of the spell but it may well refer to the caster, so if you're really dubious of something wild I'm having then by all means don't have it, but I have never specifically heard that drow are better at tolerating anything edible than humans are or vice-versa except insofar as there's some stuff you can build up a tolerance to if you introduce it carefully and we have longer to do that in."

"At least on Earth there are differences in tolerance even between humans. Some humans can't even drink milk!" Tanya couldn't drink milk in her first life and that might actually be the (only) legitimate benefit to her new body.

"...how do they survive infancy?"

"Everyone can digest milk in infancy, but some people stop being able to later. It's much more common on some continents than others. Drinking animal milk - without turning it into cheese or something first - apparently wasn't always practiced, although it must have started well before historical times, and the - aptitude for digesting milk as an adult is heritable and it's had time to spread but some people still can't."

Tanya is going to have to recall everything she can from her first life's general education. This is probably good preparation for trying to sell the locals on steam engines or something. A pity that Belmarniss isn't interested in economics or, probably, military science, but those are admittedly much less immediately practical for most people.

"Oh, neat. Drow aren't that far removed from surface elves so if they can have milk we probably also can but I don't know if they can."

"Do halflings and orcs also eat all the same things as drow and humans?"

"Far as I know yeah. With, like, different tastes, maybe."

This feels a bit weird for unrelated species, but Tanya doesn't know how weird she should consider it to be. She still has no idea how all these weirdly-humanoid species came to live on a single planet which also shares humans and some but definitely not all kinds of animals and plants with Earth. Maybe they all share evolutionary ancestors?

"Well, then, if we happen to spot any wild fruit or nuts or berries you can test them with Detect Poison. We can also hunt if we want fresh meat for variety and spot something, but only if you know how to dress game because I don't." Probably you remove all the parts that aren't meat and then put the meat on fire? Tanya has mage blades and lots of fire so she'd definitely try it if the alternative was going hungry, but she's not terribly eager to experiment.

"I know how to do fish and bats but not the kinds of animals they have up here, but I'm willing to guess."

"If I shoot fish I'm not sure if they'll sink or float afterwards. And we'd need to find a river or lake. Maybe we'll spot wild deer or pigs or something, we can't eat a whole one anyway and cutting out some of the meat should be much easier than doing the whole thing properly." Are they done shopping?

"Just warn me before you hit a fish and I can Mage Hand it up as long as it's not a really big one." Belmarniss has nothing else she wants to shop for right now but they could try their luck getting a room.

Do they really want to get a room here with these obnoxious people? Sleeping in a proper bed for once would be nice but not so nice that it'd make it worth while dealing with someone who refuses to talk to Belmarniss.

...

Why is she reacting so strongly to this?

The locals have a legitimate security concern with drow, and they possibly shouldn't trust a human stranger to assuage their worries - for all they know, Belmarniss is coercing Tanya! Tanya doesn't even look like an adult! - anyway, it makes sense that people would resent and fear drow even if they think a particular drow isn't a threat. It's not entirely rational, but humans are just like that. Some Germanian soldiers can't be trusted to deal fairly with Russy locals even when said locals are perfectly polite and do everything the army asks of them. Tanya just isn't used to being on the receiving side.

...well, but she isn't on the receiving side, Belmarniss is. So why is Tanya taking it so badly? Did she start treating Belmarniss as one of her men, just because they were together for a while and trusted each other to guard their sleep? Tanya hasn't had any relationships outside the military since she enlisted, so her subconscious seems to have slotted Belmarniss into the closest available category. And Tanya would be furious if someone treated, say, Lieutenant Serebriakov this way because her family were Russy immigrants, not that Visha would need Tanya's help in putting someone like that in their place.

Alright, but this kind of overprotectiveness for a civilian associate is ridiculous, inappropriate, and possibly even insulting. Belmarniss is a capable young woman and if she chooses not to take offense then it's certainly not Tanya's place to do so for her.

"If you don't mind the locals' attitude. Do you think it will be better in the city, because it's much bigger and has more immigrants - and presumably different species - or just because it's farther away from drow territories?"

"It might not be farther away from drow territories, I don't know if they've got apertures there, but it'll be more cosmopolitan, more adventurers from all over. I was not expecting to be welcomed with open arms the minute I stepped into the sunshine? That would frankly be weird."

"Maybe I have higher politeness norms and they don't think they're making a big deal, you're not reacting like it's one."

"Nobody has attempted to stab me!"

It takes Tanya a few seconds to realize that Belmarniss is joking.

"I hope it will be better in the city." After all, Tanya is also a foreigner who must depend on the locals' goodwill and welcoming attitude.

"That'd be nice."

Tanya will (very politely) ask the store clerk if there is an inn or similar establishment in the village, and if not, whether he he can recommend anyone who might be willing to rent them a room for the night.

"...there's a pub," says the general store clerk, looking dubiously at Belmarniss. "Got a couple rooms."

Then they will proceed to the pub and ask to rent a room for the night. And if there's a private bath, Tanya would like to use it. They don't need to heat the water, she can do that herself.

(In order for dubious looks not to make her uncomfortable Tanya has to keep in mind that the locals are wrong and she is right, and this might be readable from her face.)
