I don't watch it but my sister always does and makes me too. I've seen that Fritz and her have become engaged and that crazy psychic sister. But anyway.
If Chief Johnson is INTJ (She definitely has Ni and is T something).
The Lieutenant guy who she had an affair with played by J.K. Simmons, be ESxP? He seems to rely on his principles primarily so I'd say Fi, and he doesn't care for what-ifs, he focuses on the concrete and real, so Brenda's suppositions don't tend to impress him until he sees her winding down and coming to real conclusions, so I suppose he focuses on results. He seems to be a perceiver, or at least compared to Brenda since he's so cautious, but that could be because of his job. A lot of this could be actually. He's not so focused on the rules where it gets people in trouble so I don't think he's too obsessed with structure (ETJs seem really adamant about that - then again I don't know much about the ESPs specifically except that they seem to have a lot of energy).
What do you all think?
