Why did Ruby betray Cook in Chicago P.D.? Season 12 storyline, explored

In Chicago P.D., a betrayal by one character is always a game-changer. Season 12, Episode 19, was such in the form of Cook's reliable informant, Ruby Rios, betraying her under coercion. Ruby's betrayal—perjury under oath, deceiving the team, and ultimately assisting Damone Russell in evading justice—is the evil of this episode. Why, however, did Ruby betray Cook, particularly after all that they had endured together? Let us break down the intricate motives of Ruby's actions and the lasting consequences.

Ruby's betrayal is not straightforward —it was motivated by a mix of self-preservation, an abusive relationship, and a life of sins. In an under-pressure situation where loyalty is repeatedly tested, Ruby's choice to leave Cook was not a personal act of evil. Rather, it was a desperate act to leave something that was hers, showing how low-level survival can sometimes be in opposition to morality.

Ruby's Betrayal in Chicago P.D.: An act of desperation to save herself

Ruby's betrayal in Chicago P.D. was a moment of crisis, but not out of mere malice. Instead, it was an act of desperation on her part due to her self-sabotaging relationship with Damone Russell and her hard decisions. Ruby was already deep into the life of crime, one that escapes required desperate gambles. She was totally absorbed with Damone, and he was the center of everything she did. Ruby was more committed to him than to Cook, and she decided to defend him above everything else, even before her affair with Cook.

Recapping the highlights of the series validates that Ruby's actions were not in spite of Cook but for her self-preservation. Ruby found herself between a rock and a hard place, torn between loyalty to Cook and duty to Damone and her other criminal acquaintances. Her choice to assist Damone in nearly destroying the investigation was motivated by self-preservation. Ruby viewed the act of betrayal as a way to leave behind a life she could no longer continue leading.

The poisonous relationship with Damone: Ruby's motivational impetus in Chicago P.D.

The clincher for Ruby's treachery was her poisonous, complicated relationship with Damone. The relationship sullied her sense of right and wrong, driving her to keep him ahead of Cook. Ruby's loyalty towards Damone manifested in the way she tried to deceive the team and hide his role in the case. That she was willing to assist him, even in such patent danger, indicates how far she was willing to protect him because, to Ruby, the affair with Damone was an escape from life.

As Ruby's personality develops, one knows that she is so clouded by this poisonous relationship that she cannot think morally right. Although the television show does not explore enough about her inner struggle, it is obvious that Ruby's devotion to Damone distracted her mind and allowed her to betray Cook and the team.

The fallout: Cook's emotional and professional struggles in Chicago P.D.

The betrayal cut Cook deeply. Professionally, it ruined her trust in Ruby, her initial confidential informant, and personally, it was a bitter pill to swallow. Cook, who had trusted Ruby with critical information, had to learn the hard way that not all informants are savable or reliable. The betrayal was a turning point in Cook's character development, pushing her to a place of vulnerability and self-reflection.

Emotionally, Ruby's betrayal set Cook on a course of self-improvement. She contacted her estranged mother, which meant that the betrayal had struck home where she was most vulnerable. This was a turning point, both for the career of Cook and for her emotional journey. The impact of Ruby's betrayal was not just about the case—it was an acknowledgment of the difficulty of trusting within a world of betrayals.

Was Ruby's betrayal in Chicago P.D. predestined?

It's easiest to read Ruby's betrayal as the inescapable consequence of her checkered past, but the series leaves it up to us. Ruby's rap sheet and history with Damone, a volatile one, definitely played a role in what she did, but the series isn't necessarily suggesting that her betrayal was predestined. Her agreeing to assist Damone was a complex choice based on the necessity to survive, not lack of ethics. The treachery of Ruby was pathetic but circumstantial and environmental.

Ruby's character development does not provide an easy, straightforward answer to whether this betrayal was necessary. But it's easy to imagine where the pressures in her life would have driven her to this. Loyalty vs. survival was ugly, and Ruby made what she knew would give her the best chance at leaving the life to which she had been born.
