Bobby (Mark Boone Junior) is gaining screen time, but losing body parts, as the hostage at the center of this season’s latest, most ruthless faceoff. It all makes you wonder how angry Jax will get, and what he might do, when he finds out that all the current conflicts were generated by his lying, murderous mother, Gemma (Katey Sagal). And he has to find out. This is the final season for Sons of Anarchy, and there’s no way the series can end with that plot thread left untied.
