Misty spends majority of the season acting outside of the law, interfering in other people's cases and getting taken by lawyers who point out the way she does things doesn't adhere to important stuff like chain of custody etc. and then people just keep praising her for it cuz their captain died. It's not growth so much as she just gets more reckless, which is fine to watch the misty actress is great and the arm finally appearing is also interesting. But it's clear they're trying too hard to push the character into the cop role, when she clearly functions more like a PI in how shes been operating all season. I'd much rather see that with Collen as a partner, than the same 3 police sets and the same dull cop characters who do nothing.
I don't like Mariah and I won't. I think she replaced a far more charismastic character, and the role has been changed too much. Honestly, ignore Mariah and replace Cottonmouth with Mama Mabel in the same plot role and it would be 200% more interesting to watch for me. I don't empathise with Mariah, I don't even hate her, she just bores me because she does nothing but posture and when she makes the random shift from ghetto wasp to serial murderer it's unearned. I'm glad she's not coming back.
Fingers crossed they make season 3 Power Man & Iron Fist/Heroes for Hire.
