A gem of a show.
Garnet: ISTP 5w6 8w9 2w1 sp/so
Amethyst: ESFP 7w6 3w4 8w9 sx/sp (Initially thought w8, but over time her 6 wing became obvious and I think it's just her Se and/or sx-ness that had me thinking otherwise; my first impression of her heart fix was 4w3 until they focused on her not liking to dwell on her identity and instead basing it on what other people want)
Pearl: ISTJ slowly breaking down into Si-Fi as the series progresses. 1w2 6w5 4w3 sp/sx (I'm only 100% sure of ISTJ. I haven't focused on her as much because she always annoyed the fuck out me. She still has her own good moments though.)
Steven: I'm not too sure of him: definitely Ne/Si and a feeler... Maybe ENFP but something about it feels off because I see Fe in him but at the same time he has too much Ne to be ESFJ. 6w7 2w1 9w1 so/sx (Or 7w6, he's playful and has other 7 traits but I feel like he has more reactivity and focus on loyalty than the average 7)
Rose: ENFJ 9 or 2 but either way both are in her tritype.
Lars: Se-Fe ESTP 6w7 3w2 8w7 so/sp; interesting if stereotypical sensing-intuition contrast between him and his ex-friend Ronaldo -- he conforms while Ronaldo isn't afraid to get weird.
Sadie: ISFP?
Lapis Lazuli: Fi-Si INFP 4w5 so/sp or sp/so?
Greg: ISFP 9w8 7w6 2w1 so/sx
Connie: ISFJ 6w5 2w1 9w1 sp/sx
Ruby: eSTP 8w9
Sapphire: INFJ
Ronaldo: Ne-Fe ENTP 6w7 so/sx
Peridot: ESTJ 1w? 5w6 ?w? sp/so
Jasper: ESTP 8w7 3w4 7w8 sx/so
Sour Cream: ISFP 9w1 so/sx
Vadalia: I missed the latest episode she was in, but this was what she vibed to me in her first appearance: ISFP 4w3 sx
Edit: After watching that episode... She's changed. Integration to 1 and function development?
Forgot some and just didn't get enough of others to include them.
