There are a few pretty big things going on in this episode, and some of them really did not work for me. However, there were lots of other elements that brought this episode closer to the Suits I used to love so much in the early seasons. Kind of difficult to decide what to think.
Cons:
Frank Gallow dies off-screen. And apparently he gets a redemption arc because he loves his daughter or whatever. I mean... okay, maybe it was unrealistic to hope for some big soap-opera-y drama where Frank actually tries to have Mike killed, but I was kind of hoping for that. Suits is a show about moral ambiguity in a lot of ways, but sometimes I feel like there's too much time spent on attempting to nuance characters we really don't need to be nuanced. It's okay for Frank to just be a bad dude. Mike telling Frank's daughter that he was a "decent man" felt particularly forced to me. Frank threatened Mike's life, made threats against Harvey and Rachel, and the scummy things he did to get into prison in the first place were pretty reprehensible. It's not that I'm celebrating the death of a man, but... to call him a decent man? Really, Mike?
For the most part I really loved Rachel getting to assert some power in this episode. On the other hand, though, after she makes a plan to screw over her father, she spends the remainder of the episode playing emotional support for Louis and Donna instead of getting her own stuff to do. She's really been pushed to the side this season, and it's bumming me out.
