What happens to Ruby at the end of Rosario Tijeras season 4

The last episode of Rosario Tijeras season 4 ends with a devastating conclusion for Rosario's hopes for redemption and reunion with her daughter. After risking everything to protect her daughter from deadly criminals, Rosario finds herself vulnerable and betrayed.

Rosario enlists the help of allies like Gael, an undercover police officer, and Juan Antonio, an engaging psychologist, to make one last attempt to escape the threat of enemies that are closing in. However, the intended plan is upended tragically. A police operation that aims to find Ruby some safety devolves into chaos when an officer accidentally shoots her.

In the shuffling chaos, León Elías, aka El Güero, seizes the opportunity to kidnap Ruby and to turn her against her mother. He expertly manipulates Ruby to believe that Rosario has once again chosen violence and evil over familial bonds, which only amplifies her feelings of abandonment.

At the same time, Rosario, injured but with resolve, escapes from her captors only to discover that Ruby has disappeared into the hands of a new monster. She is once again alone in fulfilling what is left of her broken world. Rosario Tijeras season 4 ends with Rosario defeated but defiant, her daughter lost to lies, and the brutal cycle she once escaped waiting to begin again.
