Is there a season 2 of All Her Fault?
As of the latest available information, a second season has not been officially confirmed. The series was produced as a limited or mini-series, designed to tell a complete story in one season. However, the showrunner Megan Gallagher has said she would be open to returning if the opportunity arose.
Official status of season 2
No renewal announcement has been made by Peacock. The eight-episode arc concludes the central mystery, leaving little narrative room for a direct continuation unless new material from the source novel is used.
What cast members could return for season 2?
If a second season were to happen, industry speculation suggests the most likely returnees would be Sarah Snook as Marissa Irvine, Dakota Fanning as Jenny Kaminski, and Michael Peña as Detective Alcaras. Additional possibilities include Abby Elliott as Lia Irvine and Daniel Monks as Brian Irvine.
Notable characters who do not survive season 1 include Peter Irvine (Jake Lacy), Colin Dobbs (Jay Ellis), and Carrie Finch (Sophia Lillis). These actors could still appear in flashback sequences if the story continues, but they would not be part of a present-day narrative.
Season 2 release rumors
Media coverage mentions several potential formats for a second season: a direct continuation focusing on surviving characters, an anthology approach with a new cast and story, or a flashback-based return for deceased characters. If a renewal is announced, industry observers suggest viewers should not expect new episodes until at least 2027 due to development and production timelines.
Who plays Sam, Sarah, Esther, and Colin in All Her Fault?
Several minor characters have generated specific search queries, likely because their roles are not widely covered in mainstream cast lists. Below is what the available credits reveal about each of these characters.

Sam Alcaras is played by Orlando Ivanovic. The character appears to be connected to Detective Alcaras, possibly a family member. No further story details are available from the current listings.
Sarah: actor and character details
There is no character named Sarah in the credited cast. It is possible that some users confuse the lead character Marissa Irvine (played by Sarah Snook) with the actress’s first name. Sarah Snook is the actor, not a character name.
Esther: actor and character details
Esther Bauer is portrayed by Linda Cropper. The character is listed as a supporting role, but the available sources do not describe her role in the plot. She appears in at least one episode.
Colin: actor and character details
Colin Dobbs is played by Jay Ellis. He is identified in season 2 speculation pieces as a character whose story could continue if the series returns, though he does not survive season 1. Any future appearance would likely be in flashbacks.
