YMMV / Law & Order: Special Victims Unit S4 E20 "Dominance"

• Complete Monster: Charlie Baker had in the past raped his brother Billy, and then beat up his alcoholic father when they were caught; Charlie continues to beat his father. In the span of a week, Charlie has either killed, or manipulated the weak-willed Billy into killing, around 10 people, but not before forcing them to have sex with each other first. Then Charlie kidnapped two women, killed their boyfriends, and kept them captive on a roof where they risk dying of exposure. Charlie also framed Billy so the latter would face punishment for his crimes.
• Retroactive Recognition: A pre-Lost and The Vampire Diaries Ian Somerhalder plays a Control Freak rapist who has his dad and little brother on the neck. Said submissive sibling is played by Jason Ritter, nine years before he voiced Dipper Pines.
