Official trailer for the season.

The episode

Lyle's side of the story fills the hour. Talking with Leslie, he walks through the household: a father whose standards were humiliations, hair loss he hid under toupees, a mother who watched and did nothing, and the burglary arrest that he says pushed José from discipline toward elimination.

His claim crystallizes into the season's central legal theory — that the brothers believed their parents would kill them first. Dominick Dunne, writing from the gallery with open contempt for the defense, becomes the episode's counterweight: the voice of a public that never bought it.

Show vs. the record

Lyle's account of sexual abuse, and the claim that the brothers thought their parents would kill them, is the defense theory. He testified about a father who humiliated him. The brothers' earlier burglary case is part of the biography. Dominick Dunne covered the trial for Vanity Fair and did not believe the defense.

That testimony never became a factual finding. The episode lets Lyle tell it as memory. A jury was not required to accept it.
