That "surprise" revelation from Robin's murder uncovers a bigger story: police corruption. And it's worse than the contacts with the Baxters. Michael finds Robin's lover again, who was a reporter. He points them to a former corner store clerk, who used to receive drugs from an officer (the same we saw earlier in the season when Eugene escaped). He actually ends up shooting (in the shoulder?) Eugene as he takes the bus.
Speaking of him, Carlo's drug-addicted friend sees him and chases him but (involuntarily?) gets in an accident. He could have shot him but prefers to escape.
Finally, we see who holds the power in the Baxter family: his father-in-law. He wants some Italian friends ?) to "invest" in the new waterfront project if they can access NOLA port for "business." I don't think he will finish the season...
Final rating: 4.1/5 (I hope that corruption story will amount to something)
