Peacock’s All Her Fault followed a mother who uncovered shocking revelations about her family after her son disappeared in plain sight — but how did the season end?
Based on Andrea Mara‘s novel of the same name, All Her Fault began with Marissa (Sarah Snook) coming to pick up her son, Milo (Duke McCloud), from a playdate — only to find that she was tricked. The search for the 5-year-old revealed that Marissa’s friend Jenny’s (Dakota Fanning) nanny Carrie (Sophia Lillis) was to blame.
It wasn’t until Milo’s safe return and Carrie’s shocking death at Marissa’s husband Peter’s (Jake Lacy) hands that the truth was finally revealed. Carrie was actually Josephine, a woman who years prior was involved in a car crash with Marissa and Peter. Josephine and Marissa both had their newborns in their respective vehicles, but the former’s child survived while the latter’s didn’t.
In the moment, Peter swapped the kids so he and Marissa raised Carrie’s son without his wife’s knowledge.

“Finding his reasoning for the actions he’s taken — even though others may not agree with it — and finding the places where I’m judging him [were important],” Lacy, 39, exclusively told Us Weekly about the reveal. “But I think that he has a point where he’s completely off the rails.”
Lacy praised the show for building up to answers, adding,”Hopefully an audience maybe not agreeing with him — but understanding his reasoning — and then an episode later being like, ‘Oh, you’re a dangerous person to have around.’ That sort of dance was really fun.”
Once Marissa found out about Peter’s actions, which also included several deaths, she formed a plan to end Peter’s life and make it look like he died from an allergic reaction. Marissa, Jenny and later Peter’s sister, Lia (Abby Elliott), were the only ones who knew the truth — in addition to Detective Alcaras (Michael Peña).
“The revelations about Peter just built and built. For Lia, it wasn’t her decision to get rid of him but she saw it happen and she knew what Peter had done,” Elliott, 38, told Us. “She knew that what Peter had done to Marissa, that was going to continue. It wasn’t going to change. That’s his character. So to allow that was her revenge — in a way — of Peter breaking her spirit for her entire life.”
All Her Fault ended on a hopeful note with Marissa raising Milo with no fear — and with Jenny by her side. But not every character made it to the end with fan-favorites such as Colin (Jay Ellis) falling victim to circumstances.
“I did get a call before I started filming and they told me that I died. I was like, ‘As long as it’s in a blaze of glory, that’s all that matters,’” Ellis, 43, shared with Us. “I actually did say, ‘As long as it’s in a really great way, then I’m cool with it.’ That was fun. That was actually a lot of fun.”

Ellis also enjoyed leaning into the possibility that Colin was involved in the kidnapping.
“We talked about this a lot because every scene you shoot, there’s this question of how much are you giving away and how much does the audience know in a given moment and how much do you know, but you can’t betray, right?” he explained. “So that was something that we were constantly just working on and every take, literally, it would be like, ‘Oh it feels like you might be giving too much away. Let’s just turn the dial a little bit this way or that way.’ That was a lot of fun, though.”
Ellis continued: “We would constantly also be finding things together and realizing what someone else is doing in a given moment and how you react to the thing that they’re doing even though you have your own secret, even though you’re trying to be helpful. There was a lot going on at one time.”
All Her Fault is currently streaming on Peacock.
