There is increasing conversation now about the possibility of All Her Fault getting another season. The Peacock criminal drama series, which premiered on November 6, 2025, stars Sarah Snook as Marissa Irvine. Marissa experiences every parent's worst nightmare when her son, Milo, goes missing while at a playdate.Still, while the series is already generating a lot of buzz, it remains uncertain if there will be news about its renewal. The creator and showrunner, Megan Gallagher, has expressed that she would keep the door open for the next one, but has not been renewed yet in an official capacity.What does the showrunner actually say about All Her Fault season 2?Megan Gallagher mentioned that she would be interested in participating in a second season of All Her Fault or even something anthology-based. However, she has also stated that the show was created as a limited series in the eight-episode format, as it is based on Andrea Mara's book, and it has a continuous, self-contained narrative arc.If All Her Fault goes on from where it finishes, a few significant characters in the story will not come back, since they die in the last episode of the series. Therefore, if it continues as Season 1, it would have to be reimagined - and Gallagher sounds up for it. The writers would certainly work out a way to keep the same universe, either putting different characters in to inform the story, or even casting a whole new group of characters.Why is All Her Fault season 2 not confirmed yet?One reason All Her Fault might not get another season is that it was always pitched as a one-time story. Peacock, along with its producers, designed it to deliver a complete arc within these eight episodes. There is no book sequel yet; the source novel does not continue beyond what has been adapted.On the other hand, the show's early performance offers some hope. In its first week of streaming, All Her Fault led the Luminate rankings with 33.6 million hours watched between November 7 and November 13. That makes its launch one of Peacock's strongest scripted original debuts so far.Peacock's "All Her Fault" New York Premiere - Source: GettyBut Peacock will not rely solely on Luminate. Nielsen, which is known for measuring traditional streaming metrics, is due to publish its own data at some point. However, how the show holds its own on Nielsen's charts will heavily influence the decision to renew the series. If the show performs in the Top 10 for streaming originals, indicators suggest that it will be a very good sign.There is a precedent for turning a limited series like this one into something more than a one-and-done thing. For instance, shows like Big Little Lies were a limited story, and eventually the studio ultimately determined something like more seasons in a different format. Gallagher could choose a similar path by adopting an anthology style, rather than continuing the same narrative as before, while designing somewhat new storylines or characters, while also developing other people associated with the first illicit season.Some of the cast members who could return for the second season include Dakota Fanning, Jake Lacy, Sophia Lillis, Abby Elliott, Jay Ellis, Daniel Monks, Duke McCloud, and Michael Pena. Although based on how several of the characters' storylines came to a conclusion, any return could require reimagining the story or a time jump.Regardless, don't expect a second season yet. Gallagher leans toward the idea that she is "excited for everyone to dive into Season 1," suggesting that, for now, a choice will need to be made to let Season 1 exist on its own before the consideration of Season 2 can begin.To sum it up, All Her Fault may get a season 2, but as of now, that is not certain. The showrunner is open to it, especially in a new form, but the project was built as a limited series in the first place. The early streaming numbers are very strong, which helps its case. Still, important decisions depend on how Peacock reads the data in the coming weeks. Viewers who want more will have to watch closely, as a second season is possible but not guaranteed.
