S02E06 — Red River Rock

Carmine returns and walks into a Valera Holdings meeting, drops photographs of Nina's federal contacts on the table, and orders everyone in the room killed except Nina, leaving her alive as a warning. The Bellottis plan Carmine's death together, with Vincent rigging an explosive in a van, Mick taking the warehouse catwalks, and Carla luring a lieutenant before shooting him to extract Carmine's location. The three converge on the warehouse, and after a brutal fight where Mick is shot in the shoulder and Carla takes a hit, Carla interrupts Carmine's monologue as it gets more and more hateful and shoots him in the forehead. He falls backward into pooling water from a burst pipe and dies. Elena photographs the scene in the rain.
