First episode to have Adelita tell her backstory regarding her neck tattoo.
The titles of the episodes this season are taken from Mark Twain's novel, "Huckleberry Finn", which had the same titles for the chapters.
Antonia Pena refers to Marcus Alvarez's wife as "Izzy (Isabella)." In Sons of Anarchy, Marcus Alvarez's wife is named Diana. There is no explanation in-show for this discrepancy, whether it is meant to be the same character (the mother of Marcus's daughter Tessa) or if Izzy is a new wife and technically a step-mother to Tessa.
