Maggie Bell in non-socionics terms: she's driven.serious. competent.
Omar Adom "O.A." Zidon he seems a bit into image...maybe enneagram 3 or maybe just some Se somewhere. Emotionally bonded to his senior partner. some playfulness
Jubal Valentine seems social or affiliative or something.
Dana Mosier I dunno what her deal is. I didn't like her entry on the show.Seemed less confident than other characters. I came around to liking her a lot in later episodes. insightful/calculating and quite competent. Maybe writers or actor didn't know at first what to do with character.
Isobel Castille it's a little weird when replacement characters look so much like the previous character's actor. Hm...plays it as competent out of the gate.
Kristen Chazal Seems like an introvert. typical young geek.
Stuart Scola seems introverted and counterphobic 6 or something. seems self-protecting subtype? might just be at a protective age, too. I dunno
Overall a lot of enneagram 1,6, and 3 vibes
I'm hiding from my homework and writing this instead.
