"How so?"
"We produce a fairly standard type of slave here - devoted slaves, basically for sexual and domestic use, which retain most of their cognitive capacities, albeit under the owners' control. For most slaves, their libido is already based on their submissive tendencies, so it's basically a matter of intensifying this and removing inhibitions, conditioning subjects to obey automatically and respond to triggers, and so on. In this case, however, you have the submissive nature, but aligned with a deep masochistic drive towards annihilation of the self. That can be problematic, as this slave will have needs that other, more usual slaves, don't."
"What kind of needs?"
"The subject can function perfectly well as a regular slave, with full cognitive capacities. But it also needs to be punished into oblivion on a regular basis. It will feel deep devotion for its master - much deeper than most slaves, actually - and will love and hope to be loved by its master. But for this subject love is inextricably linked to punishment and non-existence and death. This subject's master must be able to turn it into nothing. He must be both its lover and its torturer."
The former handler purses his mouth. "Her torturer."
"Yes. But not in a merely physical sadistic way. This subject's master must seek to destroy its very existence, the core of its being, not just harm it physically. And then bring it back from the abyss. Again and again and again. It's a very complex proposition, as you can see."
"So, my question stands. How do you suggest proceeding, then?"
"Well, the subject has, so to speak, two personas now. One is anna, an intelligent, devoted slave, with many skills and capabilities which would make it a very valuable asset on the market. But there is also what I call the it-persona - the slave that seeks to disappear, to have no mind, to become blank, to be punished into non-existence, to cease to be. The slave that seeks its own destruction. Both personas are quite incompatible, in my view. Someone interested in the anna slave would no doubt find the it-persona rather demanding and tiresome, and if ignored, it would lead to the bursts of resistance which you have witnessed, making anna useless as a sellable slave. The it-persona, however, would make a sellable asset for a... more specialised market."
"What kind of market?"
"Serious sadists, basically. If we erased the anna persona altogether and left the it-persona, we would have a more marketable asset for this segment. With some intense conditioning, we could even make the subject focus more on physical masochism, turning it into a pain slut. Then there are snuff movies, of course." He sees the former handler's horrified reaction and goes on smoothly. "And then there's the third option, which I think would be best. Removing the anna-persona entirely and turning the it-persona into a drone. A mindless, unthinking drone, with entirely programmed behaviour, basically undistinguishable from a zombie. That would satisfy the subject's need for self-annihilation, leading to its mental balance - if only because its mind would have been completely flattened. And it would suffice with a more intensive course of electroshocks, stronger drugs, and programming. The subject is halfway there already, anyway."
The former handler is staring at the table. "So you don't think the anna persona is salvageable?"
"In economic terms, it makes no sense. Owners don't want complex slaves that require constant upkeep. They want sweet girls who will comply with their every whim, or pain sluts, or drones that are essentially human appliances. But this kind of depth? All this complication? No. No-one would buy this subject as it is."
"I see," says the former handler. "Well, the auction will be next week. I suppose we'll have to see who buys her and what their preferences are, and then we will let you know which option is chosen so you can make the necessary tweaks." He stands up. "Thank you. I'll see myself out."
He walks down the corridor towards the stairs, deep in thought, and turns around a corner just as the creature is being wheeled out of the display room in its cage. He stops for a second, looks down at it. Its shaven head, the thick collar, the new face. Its vacant eyes. His arousal is immediate, sharp as a blow.
The creature looks up and sees him. It stares into his eyes. And then, still holding his gaze, slowly and painfully, as if dragging a huge beast from an unthinkable sea depth, it raises its hand to its mouth and sucks on its thumb.
