Ethan Zobelle (Adam Arkin) is the head of the League of American Nationalists ("L.O.A.N."), a white separatist gang who desires to gain a foothold in Charming and force SAMCRO out. At the beginning of season 2, Zobelle moved into Charming and presented himself to the townspeople and local law enforcement as the owner of the newly opened Impeccable Smokes cigar shop on the town's Main Street. Throughout season 2, Zobelle and his henchman made several more attempts to remove SAMCRO from Charming but all were relatively unsuccessful.
In the season 2 finale, it was revealed that Zobelle was a longtime F.B.I. informant so he and his daughter Polly were set free. With protection provided by the Mayans, Zobelle was escorted to his cigar shop where he and his daughter waited for an opportunity to flee Charming to avoid SAMCRO's wrath. Polly left to say goodbye to Edmond Hayes but, when she didn't return, Zobelle reluctantly left her behind. SAMCRO ambushed the Mayan convoy but Zobelle escaped, seeking refuge in a deli occupied by school children. He attempted to call Hale for assistance but Hale brushed him off and merely informed him of Polly's death. Zobelle's life was miraculously spared when a more pending issue caused the Sons to depart. He was last seen booking a flight out of Charming in an attempt to escape to Budapest.
