This is a very strong episode that shows the intricate plotting of the overarching narrative.
I think the best aspect is seeing more of the connections between various circumstances and characters. Randy's arc looks ominous by this point and so many moments have conspired to make it so. If the politicians and businessmen were not so corrupt, Freamon would not have timed his subpoenas to coincide with the election. Rawls would not have destroyed Major Crimes with "Proper Supervision", Herc would not used the surveillance camera and mishandle a witness situation. Likewise, Prop Joe setting up Marlo's card game led to Omar being framed for murder, Bunk clashing with Crutchfield, and a very important message not being passed on. Brilliant writing!
It is not without some minor contrivances. Herc's stupidity feels convenient to the plot in some instances, likewise the absence of Marimow's proper supervision as all this unfolds.
Namond is a wonderfully realised character and you cringe for in every facet of life that the writers put him through. This is a perfect depiction of a person's upbringing and environment colliding at the crucial time in their life. Julito McCullum is superb in the role and this is a strong episode for the character.
Omar and Bunk have another great scene together which is well written and exceptionally performed by both actors. Michael K Williams in particular, really makes you feel for the character in a difficult position.
Colvin's mini Hamersterdam project in the school is starting to take shape, with some compelling scenes generated from the special class and Prez's class shorn of troublemakers.
All the scenes involving Carcetti as the mayor incumbent are strong and feel authentic to what you imagine goes on in these instances. I've lost count in my professional environment how often a new boss has sat with people looking to observe and understand the business.
It is one of the best episodes for visual storytelling. I loved the scenes with Greggs working her way through a crime scene that from the cinematography and set designs you can just about figure out what happened to the victim. Although it doesn't feel implausible that she would proceed as she did without backup. Particularly after being shot previously.
