8. Goodbye, Tara
Season 6, Episode 13: "A Mother's Work"
For all the organizations that have jostled with SAMCRO — the Mayans, the Nordics, the Triads, the IRA, the ATF — the real conflict has always been between Jax, who wants a better life for himself and his family, and his mother Gemma, who won't let him leave. At the end of Season Six, the club's leader decides to do jail time in exchange for the federal government leaving the group alone. But Gemma assumed her daughter-in-law was about to spill secrets to the feds, and just when it looked like everything's going to be OK, Mom stabbed Tara in the head repeatedly with a barbecue fork. You could practically hear the sound of people yelling "What the fuck just happened?!?" from Bakersfield to Bangor.
