Okay, so probably not a lot to do with Winston (although he is fluent in Spanish), but Nicola maybe? Former navigator and with family originally from TJ. He has a niece who is in training as a pilot so Ricky could know her.
Tracey of course is crew! Yay crew! Her crew are the fame she never had and she's there is not a thing in the Sold that she wouldn't do for them. I thiiiiiink that her and Ricky would get along? She also side eyes Macy sometimes because Macy reminds her a little too much of her mother for comfort, but that's not really of Macy's doing. Other than that, she's chill with the crew.
Kirby's chatty so she'll probably interact with him at some point, and the TS were the ones who rescued the kidnappees so he would know her face through that. She's not Leona, I swear ;)
