I can't believe I didn't see this thread sooner. I love this show!!! My favorite characters are Gemma, Jax, Opie, Juice, and Chibs but they don't show him that much.
I don't think Jax is going to leave. There really wouldn't be a show without him. Clay needs to die, but I think when Jax goes to kill Clay he will be interrupted and won't be able to do it. I also hope they don't kill off Juice. I feel sorry for him.
