Then I guess we'd talk about which of the options that left available you and she preferred.

Sigh. "Well, let's leave her where she is at least for now."

All right. Do you want her to know you also have somewhere to spend the night?

"Assuming that's as harmless an offer of peace of mind as it sounds, yes."

I'd expect it to be straightforwardly reassuring, yes. I'll write to them.

"Thanks."

Did you want more lighting in your room?

"It's fine."

Is whatever you're doing in here dangerous to anyone else?

"The lights? No."

Are the lights the only thing you're doing?

My job is to protect these people.

"I'm not setting out to endanger anyone and have taken precautions."

I don't know enough about you to guess whether those are adequate for my risk tolerance.

"I think the risk is extremely small. I just can't positively guarantee it's harmless the way I can with the lights."

Nod.

Can it be made smaller?

"Only very elaborately in a way that would introduce other risk."

Other risk to you or to us?

"Mostly you."

Sigh. 

All right. 

"Is there anything else?"

I don't think so. 

I suspect my father would be delighted if you showed him the lights. 

"Well, I suppose there's no further keeping them secret to be had."

We are generally willing to make commitments that make us safe to tell things, for what it's worth.
