Big Little Lies · A Viewer's Companion
Monterey's tangle isn't dynastic — it's domestic. Madeline's ex-husband married Bonnie, so both wives stand at the same school gate; Jane arrived in town with a five-year-old and a secret; and one man on this chart connects three of the families in ways the show takes two seasons to admit. The teal border marks the Monterey Five — the women bound together by what happened on trivia night — fog grey the husbands, exes and grandparents around them, and gold the first-grade class caught in the middle.

The show's whole engine is that these households keep colliding — at drop-off, at birthday parties, and finally on trivia night.
Jane moved to Monterey carrying the memory of the man who raped her six years earlier — Ziggy is that assault's child. In the season 1 finale she realizes the man is Perry Wright, Celeste's husband, in the same instant the other women do. The show treats it with gravity, and so does this chart: the dashed line is a fact, not a twist for its own sake. It makes Ziggy the half-brother of Max and Josh — something the boys themselves work out in season 2.
At the school's Elvis-and-Audrey fundraiser, Perry finds the five women on a stairwell and attacks Celeste. In the struggle, Bonnie pushes him and he falls to his death. The five agree to say he slipped — and that shared lie, not friendship, is what welds Madeline, Celeste, Jane, Renata and Bonnie into the “Monterey Five” of season 2. Teal border = party to the lie.
Madeline's ex-husband Nathan married the younger, serene Bonnie — so Madeline attends every school event alongside her replacement. Each of Madeline's daughters belongs to a different marriage: teenage Abigail is Nathan's, first-grader Chloe is Ed's. When Abigail chooses to live at Nathan and Bonnie's house, it lands on Madeline like a verdict.
Perry's mother arrives in Monterey politely refusing to believe her son simply slipped. She interrogates the Five one coffee at a time, and then goes further: a custody suit against Celeste for Max and Josh. Her own history — her other son Raymond died in a childhood car crash she was driving — is the wound under the mission.
On the first day of first grade, someone chokes Amabella — and she points at Ziggy, the new kid. Renata declares war on Jane; Madeline takes Jane's side; the whole town picks teams. Season 2 quietly corrects the record: the bully was Max, one of Perry's twins. The kids re-enact the parents' story in miniature.
Three blond boys, three daughters across two marriages, and three husbands who blur together at the school gate. Keep these apart:
Three little blond boys, all — it turns out — Perry's sons. Max and Josh are Celeste's twins (Max is the season 2 bully; Josh is the one who tells). Ziggy is Jane's boy, raised with no idea who his father was.
Whose daughter is whose: Chloe = Madeline & Ed. Abigail = Madeline & Nathan (her first marriage). Skye = Nathan & Bonnie. So Chloe and Abigail are half-sisters, Abigail and Skye are half-sisters — and Chloe and Skye aren't related at all.
The husbands. Ed Mackenzie = Madeline's now. Nathan Carlson = Madeline's ex, Bonnie's now. Gordon Klein = Renata's, whose securities fraud takes the family fortune down in season 2.
Why Abigail's surname differs from her mother's: Abigail Carlson kept her father Nathan's name; Madeline became a Mackenzie when she married Ed. One household, two last names.
Ziggy Chapman is a Chapman by name and upbringing — Jane's alone — but a Wright by blood, which is exactly why Mary Louise starts offering Jane money for his future in season 2.
The two women bound through Perry from opposite directions: Celeste his wife and victim inside the marriage, Jane his victim from one night years before. They become allies before either knows what connects them.
Season 2 pairs each mother with her own mother. Elizabeth Howard, Bonnie's, arrives with second sight and a history of having hit her daughter — the trauma that shaped how Bonnie reacted on those stairs. She dies of a stroke mid-season.

The Carmel detective who never believes Perry slipped. She closes season 1 watching the Five on a beach — and spends season 2 waiting for one of them to crack.

Jane's gentle coworker at the Monterey Bay Aquarium and, in season 2, her first relationship since the assault — briefly suspected of talking to the police.

Owner of the Blue Blues café where half the season 1 scheming happens; sweet on Jane by the finale.
