A Private Life - Episode 12 Six Feet Under: Exhumed

The homophobic killing of Marcus Foster compels David to reassert his sexuality and re-examine his family relationships. Brenda is trying her best to break from her brother, Billy. Nate goes to pick up a body when in reality, Billy had lured him there, where he displays pictures of himself kissing Nate's sister, Claire, and of Nate and Brenda having sex. He threatens Nate with a knife, but Nate is able to escape. Brenda then breaks up with Nate, telling him she needs space. Later, Billy breaks into Brenda's home, showing her that he has removed his tattoo on his lower back of the name "Isabel" by cutting off his own skin. He tries to remove Brenda's matching tattoo, but she is able to knock him unconscious and call an ambulance. She decides to have Billy committed, and she and Nate reunite. Ruth tries to push a reluctant David into telling her he is gay. She asks her gay coworker Robbie how he came out to his mother, and he tells her that it was painful and he does not owe it to her to tell her the story. Eventually, David comes out to an accepting Ruth and a disgusted Rico. At the funeral, Keith is on patrol to protect Foster's family from homophobic rioters. David assaults one of the rioters in retaliation, and Keith covers for him. Claire is concerned that Gabe's overdose was not accidental and is concerned for his well-being (from Wikipedia).
