If Dean is corrupt, he's the best actor on the planet, because he comes across totally sincere-- though also kind of weird because Murphy really shouldn't be his type, and he kind of does seem a little dim in inexplicable ways sometimes-- which seems off for a detective. It would explain why there are so many dead ends, though, like when he couldn't trace the messages, and other slowness and inaction in the case, and also he always seemed kind of slow around Jules. His willingness to cover for her when she went off the rails, though, should have been more of a red flag. Yes, partners are loyal. But corrupt cops are corrupt cops, and loyalty is a problem when it crosses into cover ups or other abuses of power.
We saw that Nia's "guy" is not Dean, he's older than Dean and balding -- when he went after Max we saw that. She could have more than one, but still-- I would rather Nia be an informant than Dean be a killer.
I liked knowing that Jess and Murphy were close their whole lives. Jess isn't just co-dependent because she met Murphy at work or something, and she's randomly glomming on to "the blind girl" out of a savior complex. It's a mess, but I appreciated the history. And we also saw that Murphy really does love Jess, in her own extremely fucked up and self-centered way.
I do not like, though, the implication that blind people somehow forget how to skate. Muscle memory! It's one thing if she would have been disoriented in a crowded rink with people zooming around and her being worried about collisions. But for her to literally not be able to stand up on them just because she lost her vision? Utter bullshit.
I guess they decided to make Felix hapless again. I don't like that. He was more interesting as a dude who was awkward and misunderstood than he is as a guy who is used and derided by someone who he seemed to have a genuine bond with.
