Katrina is my favorite character

She is polite, nice, often kind, graceful.

She doesn't flip off on people, doesn't pull rank on others, isn't a petty sucker, and doesn't deal with her traumas (if she has any) by being a humongous asshole.

If and when she pulls shady shit she is ready to face the consequences and doesn't blame others for her actions. Doesn't foster retribution, and tries to do the right thing when possible.

All while being just as competent and ambitious as everyone else in the show.

She is the closest to a good guy in the show and I love her for it.
