Hanna: ESFP, I agree about her being a reserved E though.
Emily: ISFJ (in the books. I refuse to watch that monstrosity on TV so I wouldn't know.)
Aria: ENFx? Leaning towards ENFJ.
Spencer: INTJ, I think. I can see her as an S, but that ambition of hers smacks of INTJ.
Ali: xNTJ maybe?
Ezra: hmm... idk about this one...
This thread is old but I just watched all the episodes and I'd like to talk about it.
Aria: ENFJ not sure... she's the one I relate less, probably 'cause she's the only one who lacks of Fi
Lucas: typical INTP nerd?
Sean: easy one... ESFJ
Toby: ISFP?? I don't know... but I love his character
I can't tell Jenna's type, maybe she's INTJ too... What about Melissa, Jason and the other thousands of characters?
Okay, I'm ashamed to admit it but I love this show.
And spoilers alert for the season finale btw.
Hanna - ESFP. She obviously uses loads of Se and Fi.
Spencer - ENTJ. Possibly ESTJ or INTJ.
Emily - ISFJ. The way she tried to discover A's identity last summer by printing all A's texts she received in the past was definetly Si.
Aria - INFP. INFJ could work too, but she seems to use Fi instead of Fe to me.
Alison - ENTP. ENTJ could work too, but I assume an ENTJ would be much more direct in how to boss the group around. Alison wasn't direct, she was all about manipulating the others to make them do what she wanted.
The other students
Caleb - ISTP
Mona - Her persona is definitely ESFJ and Mona as A would probably be ENTJ.
Jenna - INTJ
Toby - ISxP
Lucas - INFP. He seems much more a feeler than a thinker to me. The way he expected Hanna to dump Sean for him just because he was nice and helpful sounds more Fi to me than Ti.
Sean - ESFJ
Noel - ESTP
Kate - Exxx
Alex - ISFP
Mike - IxFx
Pam - ISTJ
Emily's dad - ESFJ
