"I wanted to set up something in terms of tension for when Jax takes over at the head of this club," creator Kurt Sutter told TVGuide.com of Tig's fatal mistake. "We'll begin with some sense of immediacy and some kind of threat." Sutter later said in March that Pope "will definitely have a strong point of view about what they did to his daughter."

Perrineau joins the previously cast Jimmy Smits, who will play Neron "Nero" Padilla, a Latino gangbanger with an exit strategy who becomes a dangerous mentor for Jax (Charlie Hunnam).

Sons of Anarchy was renewed for a fifth season back in October. FX then ordered a sixth season in February.
