After watching up the last episode (so good)
I think Lip - ISTP (down to earth; rational; doesn't see the point of conventional education as he sees 'abstractions' as intellectuals just doing 'algorithms' nothing more than that. however, very stimulated by knowledge and thinking around him, tries to conceptulzie various ways, defends his communal/societal values, but can't uphold them with the utmost superiority (inferior Fe) (what Mickey demonstrated when they were firing down a shop and called him a 'college bitch').
Lip's new girlfriend - ESTJ (down to earth, technical - pretty much consistent in her behaviour, but attempts to keep a certain degree of this objectivity to her values, keeping them at a distance - "I don't like the idea of you two getting along" but meant it in a joking or encouraging way to Lip and her dad is just a small example of how she expresses this.
Mandy - ENTJ (Rational, down to earth but at the same time, has a mysterious internal framework which allows these her ideas and commands to come to fruition ; this is secondary Ni. attempts to conceptualize others' or her own values but misses her own as a inferior Fi user may happen to do. all in all, she is not a totally vulnerable person either, she at the same time, gives the vibe of someone who will view you inferior-ly, if you don't follow her rationalizations)
Mickey - ESTP (rational; down to earth; utilitarian-approach - "i disagree, fuck you but where do you think we can find nucleur waste?" types of stances; objective but at the same time, impulsive for what's useful)
Ian - ISTJ (pretty much army oriented; quite conventional but has a deep distaste for indiviudlas who upset his internal values; could make him see Fi-dom as he is Bipolar but the thing is he does have a very rigid worldview, so he is complemented by Mickey)
Frank - ENTP (dysfunctional; total loss of Si function, and Fe to manipulate and through Ne for the millions of ways he finds gain and almost simulatenously falls into similiar patterns but on the thought of new ideas)
Sheila - ISTJ (don't see much Ni; she's very object-oriented, all Frank's shit just seems to fly about her conventional/internally-stimulated reactions to events; well until she finally breaks)
Kev - obvious ESFP (totally exclamatory in everything he does; consistent and makes use of certain people and things; like Lip; can't read but very expressive using language; the traits of a performer. )
Veronica - ISFJ (rule follower; but empathetic)
Carl - ESTP (think of an objective version of Kev, this is Carl, has Ti which allows him to count the system of ounces, etc that Frank puts forth with record ease. looks for trouble almost like its his central mode; very similar to Mickey but they never really talk so you won't see it)
Fiona - ENFJ (always caught up in a vast amount of experiences, but has little to make of each one. tries to stick to her values, and defend her family and has many things to encourage in each of her family members. one moment was almost like a Fe-Se-slap to her mother in the beginning of the series)
Debbie - ESFJ (caregiver, gives too much into what other people find 'prestigious' or 'cool', generally an issue with tertiary Ne and Ti and how it can conceptualize, but I do agree this is not always the case, but it's her consistency in these types of behaviours that makes her even more ESxJ, F is just based on the fact that it is purely not based on objective rationalizations as much as someone like Lip, but almost always personal feelings or discrepancies or criteria about her world)
Gus (fiona's new boyfriend) - INFP; deeply feeling; very valued; has an internal vocabulary that I think only a set of people in his life really understands - however, he can quite simply vocalize his feelings through fiona and his music.
Steve/Jimmy - ISTP (The guy acts like an INFJ sometimes, may be his Ni coming in; he uses an underdeveloped function to do a lot of bad things and try to fake himself into roles that aren't meant for him)
Debbie's boxing interest guy - ISFP (he puts his hand in to help, but at the same time, pushes the person away - internal discrepancies which amount to Fi-dom, but doesn't go as far as to conceptualize as much as live in the present moment - makes use of things - presents false situations and pretends they're true ("my father used to hit me all the time, so I took up boxing" really? "no aha"); almost geared toward acting roles.)
Frank's wife - some sort of ISFJ .
Frank's daughter - ISTJ?
Jody - ESFJ.
Karen Jackson (lip's braindead ex-girlfriend) - ISTP
