Our Fault Ending Explained: Why Nick and Noah’s Reunion Isn’t the Happy Ending You Think

Prime Video wraps up the Culpa trilogy with Our Fault (Culpa Nuestra), and the finale goes heavy on drama, mess, and a strange kind of happily ever after. Nick and Noah do end up back together, but the road there is chaotic, occasionally absurd, and definitely not without consequences.

How it all goes down

• Four years after their breakup, Nick and Noah still have feelings. They keep hooking up, then pushing each other away. It's a cycle.
• Noah is focused on work. Nick is running the company his grandfather left him, and in the name of profit he shuts down multiple branches. That move triggers mass unemployment and a lot of anger aimed right at him.
• After his mother's funeral, Nick and Sofia call it quits. Her parting advice:

  'Let go of your resentment and learn to forgive and love again.'

• Nick takes that to heart and sprints back toward Noah... only to learn she is pregnant with his child.
• Noah tries to leave the city. Nick chases her by car. They talk it out mid-chase and end up stopping at their parents' house.
• Then the backlash hits: one of Nick's ex-employees stabs him. He lands in a coma for months.
• When he finally wakes up, Noah has already given birth to their baby boy.
• While Nick is recovering at home, Michael and Briar break in. Briar goes for the baby; Michael's there to hurt Nick.
• Nick keeps his head, calls for help, and the police arrive in time. Their dog, Thor, also gets a hero moment and helps protect both Nick and the baby.

Why Michael wants revenge

Back in the second film, Your Fault, Noah hooked up with Michael, who was both a college staffer and her therapist. That violated every line, and he got fired for sleeping with a student.

Years later in Our Fault, Michael is working at a hospital. Word of his past gets around, and even though Noah asks Sofia to help him and Michael tries to blackmail Sofia himself, there is an inquiry. He is fired again. Reputation torched, no job prospects, and watching Nick and Noah inch toward a happy ending sends him into full meltdown mode. Then he meets Briar, and the two of them decide to act.

Michael helps plan the break-in at Nick and Noah's home and tries to facilitate Briar taking the baby. It does not go the way he hopes.

Briar's motive, and yes, it is complicated

Briar used to be Noah's college roommate, and before that she and Nick were a thing. A serious thing — she backed his worst impulses, even the reckless ones. That ended in a brutal car crash Nick caused. Briar was badly injured and says she miscarried because of it. The story around that loss is murky in the film — the way it is framed later, Briar shifts the blame onto Noah — but the key point is Briar believes Nick abandoned her when she needed him most. She was eventually admitted to a mental health facility.

Finding out that Nick moved on with Noah, her roommate, pushed her over the edge. Years later, Michael ends up as her new therapist. United by their grudge against Nick and Noah, they cook up a plan. Briar's attempt to take the baby reads like a twisted grab at control over a life she feels Nick robbed her of.

The outcome: Michael fails to hurt Nick, Briar fails to take the child, and the family survives the night — thanks to fast thinking, a timely police response, and one very good dog.

So where does that leave Nick and Noah?

Together, with a newborn, and a lot of baggage. The ending aims for hopeful, but it absolutely sits on top of everything that came before: bad choices, old betrayals, and the fallout from Nick's ruthless business decisions literally coming back to stab him.
