What Is the Cast of Bad Sisters Season 1?

Season 1 principal cast

Season 1 introduced the full Garvey family and the pressure they face after the death of John Paul Williams. The cast includes:

• Sharon Horgan as Eva Garvey
• Anne-Marie Duff as Grace Williams
• Eva Birthistle as Ursula Flynn
• Sarah Greene as Bibi Garvey
• Eve Hewson as Becka Garvey
• Claes Bang as John Paul “JP” Williams
• Brian Gleeson as Thomas “Tom” Claffin
• Daryl McCormack as Matthew “Matt” Claffin
• Saise Quinn as Blánaid Williams
• Michael Smiley as Roger Muldoon
• Barry Ward as DI Fergal Loftus
• Yasmine Akram as Nora Garvey
• Peter Coonan as Ben
• Lloyd Hutchinson as Gerald Fisher

This season uses a dual-timeline structure: past episodes show the sisters planning to get rid of JP, while present-day episodes focus on the aftermath, insurance investigations, and police scrutiny. The finale resolves the central mystery of JP’s death and the sisters’ involvement.

Season 2 cast additions and changes

Season 2 expands the ensemble with several new characters while retaining the original Garvey sisters. The story shifts from “what happened to JP?” to a new mystery involving a dead body and fresh complications for the family.

Returning roles from season 1 include Barry Ward as Loftus, Michael Smiley as Roger, Saise Quinn as Blánaid, Daryl McCormack as Matt Claffin, Brian Gleeson as Thomas Claffin, and Yasmine Akram as Nora. The Claffin brothers remain part of the broader narrative, especially through Matt’s relationship history with Becka and Tom’s earlier insurance-driven motives.

Who Plays the Detective in Bad Sisters?

The real detectives of Bad Sisters

A point of confusion sometimes arises around the word “detective” in relation to the Claffin brothers. In season 1, Brian Gleeson plays Thomas “Tom” Claffin, an insurance agent and businessman who is determined to avoid paying out JP’s life insurance claim. He is not a police detective. His younger brother, Matthew “Matt” Claffin, is played by Daryl McCormack.

The actual law-enforcement characters in the series are:

• Barry Ward as DI Fergal Loftus — the main investigator tied to JP’s death in season 1 and the body-related mystery in season 2.
• Thaddea Graham as Una Houlihan — a young detective introduced in season 2, working alongside Loftus.
• Lorcan Cranitch as Detective Superintendent Howlett — Loftus’s superior in season 2.

Why the confusion exists

In many crime dramas, the person asking pointed questions about a death is a detective. In Bad Sisters, that role is split: Tom Claffin drives the insurance inquiry, while DI Loftus handles the official police investigation. Viewers who search for the detective in the show may encounter mixed information online, but the credited law-enforcement characters are Loftus, Houlihan, and Howlett.

Will There Be a Bad Sisters Season 3?

The show has 10 episodes in season 1. The episode count for season 2 has not been officially confirmed, though it is expected to follow a similar structure. If a third season is ordered, the core cast of Garvey sisters is likely to return, but no information about potential additions or departures is available at this time.

The lack of official news keeps the show’s future open. The storylines in season 2 introduce new complications and unresolved threads that could support further episodes, but nothing has been confirmed.

When Did Each Season of Bad Sisters Air?

1. August 2022 — Season 1 premieres on Apple TV+.
2. September 2022 — Season 1 finale airs, resolving the mystery around JP’s death.
3. November 2023 — Season 2 is officially announced.
4. November 2024 — Season 2 premieres, introducing a new dead-body mystery and expanded cast.
5. Early 2025 — No renewal for Season 3 has been announced as of this date.

What Is Confirmed and What Remains Unclear About the Cast?

What Is the Background of Bad Sisters?

Bad Sisters is an Apple TV+ dark comedy-drama created by Sharon Horgan, based on the Belgian series Clan. The show follows the Garvey sisters, who come under investigation after the death of their brother-in-law, JP Williams. The series uses flashbacks and present-day timelines to build suspense around the sisters’ possible involvement in his death.

The cast has been widely praised for its on-screen chemistry, and the detective role — though often misunderstood — is pivotal to the plot. The Claffin brothers’ insurance investigation creates much of the tension in season 1, while DI Loftus provides the official police perspective across both seasons.

The lack of official season 3 news leaves fans uncertain about future storylines. As of early 2025, the show’s two seasons are available to stream on Apple TV+, and updates on renewal are expected after the full run of season 2 concludes.
