who ratted out tara on sons of anarchy
Tara Knowles Gemma confronts Tara about Providence Health & Services offer and threatens Tara "I'm done with your power push." Gemma threatens to tell investigators that Tara planned the killing of an innocent nurse to reverse RICO. Tara enlists Wendy as guardian and is now more determined to pull her sons out of Charming's "cesspool." Jax disapproves of Wendy as Guardian, but Tara insists it is her 'job as an old lady to be strong ... when and where [he] can't be." She tells him she accepted a job offer in Oregon to spare them from becoming like Gemma and Clay, which will force the boys to relive their mistakes.
Clay Morrow Clay comes to Piney's cabin in the night. After discussing trust issues and differences in the cabin, Clay leaves, only to break down the door, knocking Piney off his feet. Piney begs Clay not to get Tara involved in the letters from JT. Clay shoots Piney in the chest with a shotgun, killing him. This makes Piney the 3rd member of the First 9, and the 2nd and final co-founding member of the Sons of Anarchy to be killed at the hands of Clay. Clay leaves the markings of the cartel to implicate them for the murder. Given the club's difficult circumstances, Clay calls the Irish Kings for a meeting to set a new deal that lets them survive the war against Lobo Sonora. He later learns that the One Niners have been dealing with the Sonora and the Sons plan an attack using the Niners to lure them. This fails, however, as Sonora's men were equipped with grenade launchers. Luis, Romero's right-hand man, gives Clay a cell phone with his contact to kill Tara. Jax confronts Clay when he hears from Bobby that Clay wanted Bobby, instead of Opie, as president as was the deal. Clay says it is Tara's fault that Jax changed, but Jax warns him to never insult her like that again. Gemma tells Clay that Tara will not reveal the letters to Jax for fear that Jax will get deeper into the club out of guilt. Clay promises to Gemma he won't hurt Tara, however he uses the cell phone Luis gave him, and the next morning pays the contact 25,000 dollars for the murder. After finding out that Jax and the babies are with her, Clay desperately tries to stop the hit, but is unsuccessful and Tara has her hand broken by a car door while struggling to escape. Clay meets Romeo and gets a refund, with Romeo taking the matter into his hands personally, and Clay reluctantly agrees that Tara is best dead. Gemma confronts Clay about the hit and a violent fight ensues between the two, including Gemma shooting at Clay (deliberately missing) and getting in a powerful punch and a kick against Clay with Clay getting injured but Clay gets the upper hand and severely beats Gemma's face. That night he decides to sleep in the clubhouse. Opie later finds out that Clay was behind the death of Piney and seeks revenge, ending up shooting Clay in the torso twice. Clay survived the shooting but was shown to be in intensive care. Later in the episode Gemma gave Jax his father's letters to Maureen Ashby. After reading the letters, and realizing Clay is responsible for the death of John Teller, Jax vowed to kill Clay. Jax puts a knife up to Clay's throat and makes him step down as President and orders him to never go near his family again. Although Clay tries to explain his reasons Jax refuses to listen and takes his President patch, thus ending Clay's reign as President of SAMCRO.
