Tear Jerker: Sons of Anarchy
The entire ending to "Balm" where Gemma realizes she has to tell Jax & Clay about the rape in order to stop the rift between from growing further.
In the Season 3 opener, Gemma goes to visit her father and when he sees her he calls for her mother, not realising his wife has been dead for several months due to his having dementia. The dementia actually makes many of their scenes really sad.
In season 3, Jax decides to give up Abel. Only for the adoptive parents to end up dead, and Father Kellan sacrificing himself to save Abel from Jimmy
Juice crying and hugging Chibs after he's found trying to hang himself in the woods.
Tig being able to do nothing but watch as his daughter was burned alive by Pope in season 5.
Opie's death in season 5.
When the police come to arrest Tara, we hear Thomas crying in his room. Knowing she may never see her boys again, all Tara can say is "My babies crying." Damn, her baby is calling for her, and she can't go to him.
"I want Opie, I want Opie!" Its okay, I choked up a little to.
Venus Van Damme's tragic history.
The moment before Jax pulls a Shut Up, Hannibal! on Venus's mother. She was going on about Venus's son growing up to hate her for the life he will live with her as his mother. Jax is seen with tears in his eyes, clearly thinking of his boys and the fear of them growing up to hate him for the life he may leave for them.
So in 'Los Fantasma', we learn that Nero's gang is catching heat from a rival crew. When Samcro meets up with them, some nameless guy tries to run them down and ends up killing one of the chicano gang members. When they track the guy down, they learn that he isn't part of a rival crew, he's just a father in mourning to one of the kids that was killed in the school shooting Samcro and Nero's crew indirectly caused. The Sons spare his life, but the cops arrive shortly after. When they enter his house, he's holding a kitchen knife while staring at a picture of his son. After a moment, he drives the knife right into his throat and ends his own suffering. If any of my fell tropers have kids, now would be the time to hug them.
Clay's death and the moments leading up to it are oddly moving considering he was such a despicable character. In particular his final interaction with Juice, telling Gemma "I'm glad you're not alone", the expression on his face as he looks to her before his shot and Gemma's reaction to his death are heartbreaking.
