One note about this scene and how it's shot: Clay has the light from a window shining on his face, while Tara's in the shadows. It is exquisite staging, because it shows how, in this scene, Clay is being completely honest about what his motivations are and Tara is clinging to the notion that she's justified in lying (by omission) to Jax. I am wondering if this scene is meant to illustrate one more step on Tara's road to becoming the next generation's Gemma, choosing to keep some secrets in the dark because of her need to keep her family intact.
Clay wants the letters, and Tara says, "If you're so sure I'm not going to give the letters to Jax, why do you need them?" Clay grins and says, "Peace of mind. I want to be able to sleep at night. You can understand that. You give me the letters, I destroy them, you and Jax leave with the boys, everybody's happy. And safe." Tara asks, "And if I don't give them to you?" Clay says honestly, "I'm not sure you and Jax ever make it out of Charming."
Gemma continues sprinting -- in her heels, no less -- and runs right into Clay as he leaves Tara's room. He looks at Gemma, registers her expression, then says, "She's fine" as if he's wounded to the core by the very thought of Gemma suspecting otherwise. Gemma pauses, then calls Clay's name. He stops. She tells him, "Opie found Piney. He's certain you're the one who killed him." Clay wants to know how Opie came to that conclusion. Gemma shrugs, "Doesn't matter. Cold-bloodedness of how Piney went, history of you killing Donna. I'd watch your back. Opie will want a settled score." Clay looks at Gemma with a lot of love and regret, and nods in acceptance of what she's telling him. Gemma is cold and calm as she leans forward, takes Clay's face in her hands and says, "I love you, Clay." She kisses his cheek, then walks away. It feels like a good-bye. As Clay watches her go, he looks as it feels that way to him too.
Compartmentalizing away, Gemma's now gone into mother-hen mode, packing up Tara for departure. She digs, "What did Clay want?" Tara says, "He wants the letters. You didn't tell me he knew. Is that why this happened?" Gemma redirects: "I found that cover note. I panicked. I had to tell someone." We see Tara's shocked face; she finally realizes that Clay is somehow behind this, thanks to Gemma's big mouth. Aaaaand Jax enters right at that awkward moment. He seems elated that Tara's been released; she is not so much. Gemma goes to leave, and Jax stops her with, "You need to hear this." He takes Tara's hand and says, "I talked to Wendy. Did you really think I wasn't going to find out?" Gemma justifies her smothering with "The last thing you needed to worry about is what that ex-junkie wants." "I don't give a shit about what anybody wants -- including you," Jax says. He adds, "We're going. Tara has an offer from a hospital in Oregon. Day after tomorrow, we're packing up our boys and we're getting out of Charming." Gemma fumes in his general direction. After Jax leaves, Gemma spits out, "You have no idea what I've done to protect you and Jax." The lady with the broken arm replies, "Protect us from what? I just wanted him to know the truth." Gemma replies, "Is that what you wanted, sweetheart? Truth? 'Cause I got buckets of it. I can drown you in truth."
