Monty de la Cruz as the Physical Perpetrator
The on-screen revelation identifies Monty as the person who physically attacks Bryce in the final moments of Season 1. This confrontation occurs in the locker room, where power dynamics and suppressed rage collide violently. Monty’s actions are driven by Bryce’s ongoing manipulation and threats against him and others.
Pressure from Bryce
Bryce frequently coerced Monty into covering for him, turning Monty into a tool for intimidation and control. The toxic environment of the school allowed Bryce to exploit vulnerabilities, making Monty both aggressor and victim in the broader narrative.
Zach Dempsey’s Personal Vendetta
Zach’s involvement stems from deep personal betrayal, particularly Bryce’s assault of Hannah and destruction of Zach’s relationship. This emotional wound fuels his desire for retribution, even as he struggles with guilt and fear of consequences. His decision to harm Bryce is framed as both crime and catharsis within the series.
Friendship and Betrayal
Once close, Bryce and Zach’s friendship collapses under the weight of Bryce’s entitlement. Zach’s journey illustrates how complicity and silence among peers enable abusers, and how that complicity can explode into irreversible acts.

Alex is drawn into the plot under duress, reflecting how Bryce’s influence radiates through the group. The series emphasizes that those pressured into assisting may face legal consequences even when not the primary attacker. Alex’s arc explores accountability, remorse, and the difficult path toward redemption.
Therapy and Testimony
As Alex recovers from his injuries and mental health struggles, he gradually accepts responsibility. His cooperation with law enforcement and willingness to testify mark a turning point, showing how confronting the truth can reshape justice.
Broader Social Culpability
Beyond individual hands, the show interrogates institutional failure by examining how adults, school policies, and peer culture enable predatory behavior. The audience is pushed to consider responsibility not only for the direct act but for the environment that allowed it to flourish.
Systemic Neglect
Coaches, teachers, and parents overlook warning signs, prioritizing reputation over student safety. This collective neglect becomes a silent accomplice, underscoring that the question “who killed Bryce Walker” is also a question about societal complicity.
