How accumulated body count has led SAMCRO to a crossroads (NSFW; SPOILER ALERT! Includes midseason finale scenes at end of slideshow)
''Straw'' (season 6, episode 1)
RIP: School shooting victims
Death by: Bullets
Reason: What seemed to be almost a throwaway plot point in season 5 Jax agreeing to sell the Byz-Lats a few KG-9s led to one of the show's most controversial moments as Sutter set in motion a story line that he described to EW as, ''the final straw in [the club's] relationship with the gun business and the domino that takes us to a fairly tragic and epic conclusion.''
Result: Throughout the season 6 premiere, we caught glimpses of 11-year-old Matthew (Tate Berney), a character we'd never seen before. In the end, he sat down on a bench outside his Catholic school, rolled up his sleeves, opened his backpack, and took out a journal he then wrote in. When the bell rang, he took out a KG-9 and entered the school. ''Oh my God!'' we heard an adult yell, and then the shots came along with blood splatter on the windows and screams.
Reverberations: The shooting left four dead (three of them children), and nine injured (two critically). Matthew had taken the gun from his father figure, Nero's Byz-Lat cousin Arcadio (Dave Navarro). Lee Toric (Donal Logue), the ex-U.S. Marshal whose prison nurse sister was killed by Otto, guessed the weapon could be traced back to SAMCRO and the Byz-Lats. District Attorney Thyne Patterson (CCH Pounder) would feel the pressure to find a devil to blame.
