friendships and different kind of relationships in the vat that i would have loved to see (and how i would perceive some of them):
ilyukhina and yao (i just know they had some of the best friendships going on)
carl and stratt (a lot is talked about carl and grace, but what about them?? i think they would be pretty good friends)
shapiro and ilyukhina (ilyukhina is a menace, just add annie no-filter shapiro to olesya innuendos ilyukhina and they would be so chaotic above the vat, i know they would bully grace when stratt is busy)
yao and stratt (i'm pretty sure they could also develop a really good friendship)
ilyukhina and grace (sorry but i'm a sucker for them being little sister-older brother coded)
dimitri and grace (this friendship is kind of canon in the book so, to see more of them, maybe even seeing dimitri and ilyukhina racing grace to drink, of course grace is out really quickly at ilyukhina's and dimitri's comparition)
lokken and stratt (lokken actually being everyone's mother figure on the vat sorry, i'm a sucker for parent figures, i have issues okay. i know my perception of lokken may have changed a little with the movie, but i really think that lokken and stratt would get along just fine, they both seem rough at first but after spending a while with them you get to the conclution they are both really nice people)
yao and grace (yao is a person i think grace would reach out looking for some guidance, in the movie yao is the only one grace approaches to say "thank you for what you are doing" and i think yao's words really stayed with him, so yeah i think their relationship, friendship, or however you want to call it or see it, would be really nice to see)
