"I hope you run into something nastier than you are."

"I'm indestructible. Look, I just wanna try a thing that'd knock a human out temporarily. Won't do worse than a mild headache unless you have a non-sunlight weakness that humans don't have."

Her eyes narrow. "Fine."

Dose!

Either knocked out or pretending very convincingly.

Cam's computer makes a loud startling noise!

No twitch but maybe it's easier to not twitch if you don't need to breathe or have a heartbeat or whatever.

He waits for fifteen minutes and if she's not up by then he tries the antidote.

She doesn't react to that either.

That begins to be slightly concerning.

Itching powder on her foot?

After a minute she shifts slightly to rub it against a rock.

"Hello there. I can't use this result, unfortunately."

She opens her eyes to glare at him. "Don't you have anything better to do than harass people?"

"I'd like to be in sub-Sarahan Africa eradicating malaria. Unfortunately, my information about the state of the world isn't up to the level I prefer to have when I'm making large ecological changes."

"That sounds like a fine thing to do. Not very evil, I guess. You could replace it with having mosquitos bring their blood to the shrine of a hellgod or something?"

"I'm not trying to be evil!"

"Well, I'm just making suggestions," she pouts.

Sigh. "Hellgods are a going concern?"

"I've heard about them. I haven't met any. I guess they could just be demons putting on airs."

"Tell me about those," he says.

"They're from hell dimensions and they don't come here much but when they do they try to suck us into a hell dimension or whatever?"

"And vampires are a different thing, not directly related?"

"I haven't exactly read a book about it. Pretty sure I'm not from a hell dimension. I guess I'm in favor of hell dimensions, you know, 'cause they sound pretty evil."

"Were you evil in life?"

"Nah, I was boring as fuck."
