"Actively hostile?"
I glower at him.
"All right," he says. "Tell me more. Have you encountered one? I have not. Very few of us here have. I presume Eric would be the exception."
I tell him about Dalton's experiences.
"Now, that is interesting. He is correct that it may not have been mud. Did you know psychiatric patients sometimes smear themselves with feces?"
"I've heard of it."
"It's common enough that there's a term for it. Scatolia. Do you know why they do it?"
"Because it's disgusting."
He shakes his head.
"I'm serious," I say. "My presumption would be that they do it because it is repulsive. It's defiant, and it elicits a reaction."
"Yes, in cases like the ones you may have heard of--likely connected to violent offenders--that is the primary purpose, along with acting as an expression of anger, frustration, and helplessness. It can also enforce social isolation."
"Surprisingly."
"In other instances, scatolia can simply be an act of self-control. However powerless one may feel one always has the power to do that ... while, yes, using it to elicit other responses."
"Enacting control over others in the only way possible."
"Precisely. And yet smearing oneself in feces--or even mud--can serve another purpose. What was Eric's reaction?"
"Get the hell away from the crazy guy."
"Precisely. Which is why some prisoners will do it. Taking off one's clothing. Adorning oneself with random items. Smearing substances on one's skin. It is stereotypical 'crazy' behavior. I have assessed many prisoners who did it. Few were actually mentally ill."
"They just wanted an NCR ruling?"
"Not criminally responsible. Yes."
"Everything these hostiles do could fall into the same category. Acting violent, acting crazy. But what's their motivation?"
Mathias stares at me as if I'm asking why we live in houses instead of just laying out sleeping bags in the street.
"The obvious answer is to scare us," I say. "A threat display."
"Yes..."
"But what's the point? How are they being threatened? Look at the settlers--Rockton doesn't bother them, and they don't bother each other. There's so much land out here that territorial disputes would be ridiculous."
Mathias leans back, purses his lips. "You are correct. And this is why you make a good detective, Casey. You do not presume the obvious without thinking it through. I have been up here too long, with too few puzzles to solve."
"Well, here's one for you, then. If the hostiles are sane, why act like madmen to scare off nonexistent threats? If they are not sane, how did they get that way? Again, there's a presumption--they leave civilized life and revert. But revert to what? This isn't some 'pre-civilized' form of human. That plays right into the old idea that we are all one step from savagery, base and violent creatures. The other explanation is that they left Rockton because of some dormant mental illness. But if so, why does it all seem to present in the same form--primarily, violence? Does it make sense that every hostile out there is suffering from the same mental illness?"
He doesn't answer for a long time. Then it's only to say, "I need more data."
"Such as..."
"A l
ive specimen would be ideal." He catches my look and sighs. "All right. For now, I will settle for all reports on encounters. Bring me everything. Then we will speak of specimens."
