6. Otto Borrows a Crucifix
Season 5, Episode 10: "Crucifixed"
Kurt Sutter had cast himself occasionally on the show as Otto Delaney, a club member and rough customer who serves SAMCRO's interests inside the state prison. Pressured by the U.S. attorney's office to rat, Otto concocts a bizarre plan. He asks Tara to bring his late wife Luann's old crucifix into the prison, and then uses it to murder a nurse. The killing temporarily keeps Otto from having to snitch, but it also gets Tara in trouble with the law, putting Jax in a precarious position.
