A trio of live-in secretaries that Delta designed for and gifted to Kit. As Delta tells it, Kit had gotten him a particularly thoughtful gift (a sturdy new phone case, and a box of his favorite chocolate-covered-mango snacks) and this seemed like the most appropriate way to respond. Kit still isn't exactly sure what they are, but he's jotted down all the flippant answers they give him when he asks. So far, he's narrowed it down to "hard light constructs", "sentient nanobot clusters", or "ghosts". Whatever they are, they seem harder to damage and easier to reprogram than the average person. They don't seem particular fussy about their names- Kit calls them "AJ", "Alaska", and "Aiden" for the most part, but they respond just as well to "One", "Two", and "Three".
The trio is designed to do (and be) absolutely anything Kit wants - though most of the time that just means menial tasks, general companionship, and extra players for game night. Sometimes, though, their advanced predictive technology leads them to fulfilling desires that Kit is too embarrassed to discuss, or that he isn't even aware of himself yet. Delta, of course, finds this incredibly hilarious and keeps making excuses whenever Kit asks if they could be modified to not do that sort of thing anymore. The AIs also find it hilarious, which is why they keep doing it. He's tried asking them nicely to stop, but every time it's suddenly "sorry boss we're malfunctioning" this or "actually we're ghosts and the First Law doesn't apply" that. Who would've known artificial intelligences would be so damn smart.
