Beckett: Gryffindor Beckett always puts her own needs behind others. She protects people that are scum, because it is her job and she knows that it needs to be done. She doesn’t want anyone to die that doesn’t have to, even if they are terrible people. She is very brave and charges into situations head first.
Alexis: Ravenclaw It is strange that the voice of reason comes from the daughter in this show. Many times, that role is taken on by the parent, but not here. Alexis is very logical and inquisitive. She takes a job at the morgue because she wants to learn as much as she can. She also applies for college early and uses her brain before making rash decisions.

Esposito: Gryffindor Esposito is very brave. He also isn’t afraid to get his hands dirty in the sake of carrying out his own justice. He wants the truth and isn’t afraid to make a few enemies on the way.
Ryan: Hufflepuff Ryan is also very brave, but his loyalty to his friends and is wife are much more defining traits. He is always there whenever anyone needs him and is willing to take on extra work to help the team.
Lanie: Slytherin Lanie has a no questions asked attitude that makes her very Slytherin. She knows she is intelligent and very good at her job. She also makes sure everyone else knows that. She isn’t afraid to be brutally honest.
