"Are you a mortal?"

Not a question he expected to get asked! "Yes."

"Human, or some other species?"

"To my knowledge I'm human."

--he is an incompetent and he is going to be purified in the fires of Hell.

"Give me a second, I'm going to put up a Zone of Truth. --Do you have magic on  your plane?"

... What is he doing? "Some people believe in it, but I've never seen any personally. Unless defibrillators are advanced magic." He smiles before realising that joke probably makes no sense to the person questioning him.

"We don't have that spell. --People who are in a Zone of Truth can't lie. It'll last ten minutes. Just enough time to make sure that you're not someone from Tian Xia pulling something. Since I believe that Zone of Truth works and you don't, I should ask you questions under it and not the other way around." Just in case he can't throw it off (he can) or evade the truth without looking suspicious (he can). You need multiple layers of protection.

He has no reason to believe a 'Zone of Truth' will actually do anything, that's correct, but he doesn't intend to lie. Regardless of whether one should be completely honest with unknown... Authority figures?... right now he knows nothing and if he plays nice he might know something. "Of course. Is there something I can do to help with that?"

"Zone of Truth," he says, moving his hand in a precise fashion and touching the symbol he has around his neck. (And throwing it off himself, obviously.) "Try lying."

I'm from Taldane. --That's just. Not coming out of his mouth. That's a little disconcerting.

As is seeing someone cast an actual spell with an actual effect.

Disarming smile. "I can see the usefulness of that."

"Quite. --Can you repeat the things you said before? Your name, that you're human as far as you know, that you don't know who Pharasma is or what Law and Chaos are?"

"My name is Doctor Bunnakit Songsakdina, I am human unless something I am not aware of has happened, and I don't know 'Pharasma,' 'Law' or 'Chaos.'"

"What things that you've seen so far are strangest to you?"

"On a small or large scale? On a large scale, I don't know what if injuring all those people and I sincerely hope it stops. On a smaller scale: your medics are sprinkling blood into burn patients. Do not do that." Finally, he can actually communicate the problem through something other than bucket mime.

"...why?"

"I do not know if different planes have different diseases, but on my plane that would be a very good way to spread diseases that I don't know if you can test or treat here." If they don't even have antibiotics or painkillers...

"It's Infernal Healing, it's fine, I'll explain later. --You're a medic?"

That sounds... Less than fine, but he can work out how worried he's going to be later. "I'm a doctor, yes. A medical examiner, but outside of that I mostly work in Emergency."

"And you have different healing magic? A defibrillator?"

Nethys! Leave the anomaly alone!

okaaaaaaay but it wouldn't be entertaining if he had a meltdown about magic existing. It is much more entertaining if he just casually accepts it as a fact of the world! More people, to Nethys's mind, should casually accept magic as a fact of the world. This would lead to more cool magic.

SHE IS FILING A REPORT WITH PHARASMA

Don't you want to see what happens if you combine magic with the germ theory of disease?

NO

"Defibrillators aren't magic. If you have a heart beating in a dangerous rhythm, if you shock it with electricity, it can restart with a better rhythm."
