Late in Other Mommy, the scary feeling moves in. It stops sitting at the edge and starts looking her in the eyes. Bela is only seven, but she finds out ugly details about her own family. On top of that, she has to deal with the thing that has lived near her house for a long time. Rob Savage directed the movie. Jessica Chastain is in it twice, as Ursula, and as the figure people call Other Mommy.

Other Mommy shows up in a way that makes no sense at first. It comes from Bela’s closet. It keeps pushing for access, like it has a right to be there. Early on, it seems almost friendly. It speaks in a soft way, like it can fill the gap that Bela feels at home. Then the tone shifts fast. The nice act falls apart. Bela learns what the creature really wants. It asks for her to say so. Once she gives it, it can take over.

What happens at the end of Other Mommy?

The final confrontation begins right after Ursula finally says what is on her mind. She tells Bela that she was married before Russ ever came into the picture. In their house, Russ is what everyone calls “Daddo.” Then Ursula adds that Bela is not his child by blood. Still, Russ does not leave. He stays where he has always been in Ursula’s world, and he raises Bela as if she belongs there.

Ursula does not stop. She says something even crueler. She admits she never felt like she wanted to be a mom. Bela hears it and it lands hard. It brings up old feelings that Bela has carried for years. After that, Bela starts to ask herself where she really fits with them.

Bela gets stopped by all of it. She pulls away from her parents. For a second, it almost feels like she will go along with what Other Mommy says. But she does not. She pushes back, instead of letting the thing move in.

Their last moment happens in the bathroom. Other Mommy wears Bela’s face, then asks the real girl for a hug. When it tries to come closer, Bela jerks back. She tears the creature apart. That is the point of the fight. It proves what Bela will not accept. She will not let fear and pain lead her.

Once she takes on the monster and makes the secrets come out, she starts to understand what is going on with the people around her.

Is Other Mommy really dead?

Bela finally got what she asked for, and after that, the family kept going. In a bit, they are side by side, putting up Christmas lights. From the street, it might look fine again. But Ursula cannot drop the thought.

The fear stays in her, even when she tries to act normal. So it is tough to say the family is safe; everything shifts fast. A new Mommy shows up. She walks in and looks right at the lens, like she has been waiting. Then she lifts a finger and tells everyone to be quiet. The scene feels wrong. It is as if the threat is still there, just out of view. The film does not explain what her arrival means.

In the book, two family facts matter. Ursula had been married before, to Douglas Cain. Russ chooses to raise Bela even though he is not her real father. That backstory sits under everything.

The ending turns bleak. Other Mommy kills Bela’s parents. Later, Bela lets the entity get inside her. The film goes a different way. Bela makes it through the fight. Still, the post-credits moment hints the threat is not done. Her win feels earned. But the last shot also makes it look like Other Mommy’s side may return again.
