Is She My Half-Sister?

I was brought into a tent in the village. There are some people here watching me. And that girl from before is here as well.

"Weird doctor, why are you here? You're not with the cult but I still can't trust you," the girl said.

"I have a lot of questions to you but I'll ask later. It's my turn to be asked I guess. I'm here to look for any cities or villages where the people are hostile toward the cult. This is a harsh climate for anyone to live in. So I believe the cult won't come here because it will be a waste of resource if they do. There's no point in conquering a place like this for them," I said.

"Your words are not lies. Again. And it seems like you know a lot. Way more than what we know. Tell us more," she said.
