Monty has stated numerous times that he used to be biological. Presumeably human, though with their technology its entirely possible he was the family cat and was 'upgraded'. Mind you they havent said this is possible in QV universe so far.. but i dont see why that wouldnt be a thing. He could also be that space pirate boyfriend nicole used to have. But thats doubtful. Nicole's lovers never seem to work out for her. It is a bit weird actually isnt it? He clearly is more than just an employee of nicoles. I wonder where the ethical lines fall on building companions in the future? If you genetically grew a companion that was loyal intelligent non covetous or jealous and preferred nicole traits. And then hired them to guard your house at what point does it become slavery like the modified servant class in previous QV stories.? Is monty nicole's son perhaps? There are clearly problems with trust in this society arent there?. How do you keep somebody trustworthy to run your household for you for hundred of years? The only way you could make sure they werent a mole like hayami with unforeseen associations would be to build them yourself.
