I've noticed Roko has recently shrunk into a role of following Yay around, reprimanding them when they do something out of line. Similarly, Yay spends most of their time spying on others and petting various animals. I hope Jeph does more with both of them and their relationship, because they're both intriguing characters with plenty of potential storyline.
The concept of Yay especially fascinates me. Imagine they end up at a casino. Would they be drawn to games of chance in particular, because they enjoy the peculiarity of not knowing something for once, or would they be repelled by them for the same reason? Would they use their computer skills to cheat at something like roulette by predicting where the ball will land, or would they prefer to leave it up to a wild guess? I picked "casino" out of thin air here, but the same idea can be applied to any other common human situation.
Roko's relationship with them is also interesting, because while they're members of the same species, their experiences are so wildly different that they have almost no common ground. Is that a sustainable friendship? Why did Yay become friends with Roko in particular?
TLDR: I am a nerd
