Don't Blame the Kid - Ending Explained

The central twist occurs at the very end of the film during the birth of the baby. Throughout the movie, the audience is led to believe the child is Renato's. However, when the baby is born, he is clearly of Asian descent.

This reveals that during the drunken blackout at the wedding, Maru slept with a Chinese guest (seen briefly in flashbacks), not Renato. Despite this revelation, Renato recalls his bond with the unborn child and Maru. He chooses to stay and raise the child as his own, proving his love is unconditional. The film ends with a video Renato makes for his son, jokingly preparing him for the bullying he might face for looking different, affirming they are a family regardless of DNA.

The Cynical Reading: Some critics interpret the film not as a romance, but as a satire of the Mexican elite's desperation to maintain appearances. In this view, Renato is a pawn used by Maru's family to cover up a scandal, and his "reward" is being allowed into their circle only because he accepts a lie.

The Feminist Reading: Maru's character can be seen as reclaiming agency. Despite the pressure to abort or marry her ex, she chooses a third path—co-parenting with a man she initially dislikes but who respects her. However, the ending where she stays with Renato can be critiqued as her settling for the 'safe' option demanded by patriarchy.
