The show is very confusing to me. I'm not actually sure what it's even doing with Dex, Grey and Miles (and Liz, and Miles's partner, and Tragically Dead Ex Benny, and his widow, and whoever). So Dex is a huge work-in-progress kinda girl, where she does one step forward and two steps back from time to time. She cares for Grey a lot, she's afraid to lose him as he is her family. She likes Miles because he's sexy, professional and also generally a nice guy. Miles so far has very superficial relationship with Dex based on their attraction to each other and him being generally neurotic and obsessive over herl. Grey is only one, out of four parts of the complicated love construction, that projects an image of a person who has their shit together. He also understands Dex perfectly, and has being a part of her found family unit for the last six years.
The thing is. There's no actually a proper love triangle, is there? I mean, Liz seems the one who was into the idea Grey is super in love with Dex, and has been claiming there's something there between them since her first or second appearance, and there's no place for anyone else in Grey's heart. But Liz is not exactly a sane kind of person, since she was actively trying to single-white-woman Dex out of Grey's life, is she? Sure, if you're paranoid it doesn't mean you couldn't be followed. But do Dex's or Grey's romantic feelings for one another actually exist? I don't know. It's hard to say with Grey, as he's a super chill dude in general, and with Dex it's even worse because she hates herself and is so very scared. I do think that Grey is the longest committed relationship Dex ever had out of all her actual love interests, including Saint Dead Ex Benny. But what's the show's stance on it? Does the show want me to fall for Miles/Dex connection or maybe I should wait for some lady that will come along for Dex to be her perfect choice?
I know one thing. I want Miles and Grey to get together because it'd be hot. And unexpected!
