It was the moment that shifted the entire trajectory of Netflix’s 13 Reasons Why. If you’ve spent any time in the fandom, you know exactly what I’m talking about. The screen went dark, the tension peaked, and suddenly, the dynamic of Liberty High changed forever. But when people ask why did Tyler kill Charlie, they are often confusing two very different, very intense storylines involving the show’s most complex characters.
Let’s set the record straight: Tyler Down did not actually kill Charlie St. George.
In fact, their relationship is one of the few instances of genuine redemption and support in a show otherwise defined by trauma and secrets. The confusion usually stems from the chaotic overlap of Tyler’s near-shooting at the Spring Fling and the eventual death of the series' primary antagonist, Bryce Walker. Because the show jumps between timelines like a frantic heartbeat, it’s easy to get the wires crossed.
The Confusion Between Tyler and the Actual Killers
If you’re looking for a body count, Tyler isn't your guy. Despite the immense, stomach-churning trauma he endured at the hands of Monty de la Cruz and his cronies in the boys' bathroom, Tyler never pulled the trigger.
The person who actually died—and sparked the massive "Who Killed...?" marketing campaign for Season 3—was Bryce Walker. Tyler was a suspect, sure. Everyone was. He had the most motive. He had a literal arsenal in his trunk. He had every reason in the world to want the people who hurt him gone. But the show chose a different path for him, focusing on healing rather than a homicide.
Charlie St. George, played by Tyler Barnhardt, actually becomes one of Tyler’s biggest allies. This is what makes the "why did Tyler kill Charlie" question so fascinating; it’s a complete inversion of their actual arc. Charlie starts as a fringe member of the jock culture that enabled Tyler's abuse, but he ends up being the one who helps Tyler feel safe again. He's the one who stands up to Monty. He’s the one who joins the group to protect Tyler from the police investigation.
Understanding Tyler’s Breaking Point
To understand why people even think Tyler was capable of murder, we have to look at the end of Season 2. That scene in the bathroom—the mop handle scene—remains one of the most controversial and difficult-to-watch moments in modern television history.

It was a tipping point.
Tyler Down was a kid who had been bullied, sidelined, and humiliated for years. When Monty assaulted him, it wasn't just another instance of bullying; it was a total violation of his humanity. This is why Tyler brought a semi-automatic weapon to the school dance. He wasn't looking to kill "Charlie" specifically; he was looking to erase the environment that allowed his soul to be crushed.
Clay Jensen intervened. That’s the pivot. If Clay hadn't stood in front of that door, the answer to "who did Tyler kill" would have been a long, tragic list of names. But Charlie St. George wasn't on that list. Charlie was actually a sophomore at the time who wasn't even involved in the core bullying group until later, when he began to distance himself from Monty’s toxic influence.
Why Charlie St. George Stayed Alive and Became a Fan Favorite
Charlie is a "good jock." It’s a trope, but in the context of 13 Reasons Why, it felt like a necessary breath of fresh air. Instead of a victim-perpetrator dynamic, the writers gave us a story of accountability.
- Charlie realized the jock culture was poisonous.
- He helped plant evidence to protect the group (specifically frames Monty for Bryce’s murder).
- He entered a healthy, loving relationship with Alex Standall.
So, if you’re searching for the motive behind a murder that didn't happen, you’re likely remembering the intent rather than the action. Tyler had the intent to kill many people. He had the firearms. He had the plan. But through the intervention of Tony and Clay, he spent Season 3 recovering his guns from the river and going through a grueling, "recovery" process where he had to face his victims and his potential for violence.
The Real Killer in Season 3
If you are actually thinking of the death that drives the plot, it’s Bryce Walker. And Tyler didn't do it. Alex Standall pushed Bryce into the freezing water after a confrontation on the pier, and Jessica Davis watched it happen.

The reason Tyler gets looped into these "killer" theories is that he was the most obvious candidate. He was the "kid with the gun." The show plays on our societal assumptions about who becomes a school shooter. By making Tyler an innocent in the Bryce Walker murder, the show challenged the audience to look past the stereotype of the "damaged kid" and see the person underneath.
The Narrative Shift: From Violence to Vulnerability
Honestly, the show handles Tyler’s arc with a lot of weight. You see him go from a boy who felt his only power was behind a lens or a trigger, to a young man who found power in his voice.
Charlie St. George plays a massive role in this. Charlie is the bridge. He represents the "other side" reaching out. When Charlie and the others help hide Tyler’s past, they aren't just covering up a crime (the attempted shooting); they are giving a human being a second chance at life. This is why the idea of Tyler killing Charlie is so jarring to those who watched the series closely. It would have destroyed the most redemptive arc in the show.
How to Distinguish the Characters and Plots
If you’re still confused, let’s break down the "Who" and "Why" of the final seasons:
- The Victim: Bryce Walker (Season 3).
- The Killer: Alex Standall (pushed him into the water).
- The Scapegoat: Monty de la Cruz (died in jail, framed by the group).
- The Protector: Charlie St. George (helped frame Monty to keep his friends safe).
- The Survivor: Tyler Down (survived his trauma and didn't become a killer).
Tyler’s journey is about the struggle to not kill. He spent every day fighting the urge to take revenge on a world that had been incredibly cruel to him. The fact that he chose to photograph his friends, to go to prom, and to eventually find a semblance of peace is the core message the writers were aiming for.
What to Watch for in the Final Season
By the time Season 4 rolls around, the bond between these characters is sealed in blood and lies. Charlie and Tyler are firmly on the same side. They are part of the "core group" that is haunted by the secret of Bryce’s death.

If you are going back to rewatch, pay attention to the scenes where Tyler starts to trust the athletes again. It’s a slow burn. It’s awkward. It feels dangerous. But Charlie St. George is the one who makes it feel possible. He treats Tyler like a person, not a ticking time bomb.
Actionable Insights for Viewers and Fans:
If you’re diving into the lore of 13 Reasons Why or writing your own analysis of the show, keep these points in mind to avoid common factual errors:
- Verify the Season: Most "killing" questions refer to Season 3. If you're looking for Tyler's violent outburst, look at the Season 2 finale, but remember he doesn't actually follow through.
- Contextualize the Framing: Remember that the group framed Monty for Bryce's murder. This is why many viewers get confused about who killed whom—the characters themselves are lying to the police for two full seasons.
- Separate Intent from Action: Tyler’s intent to commit a mass shooting is the catalyst for the group's bond, but his action throughout the rest of the series is one of non-violence and recovery.
- Acknowledge the Character Growth: Charlie St. George enters the show late (Season 3) and becomes a moral compass. Associating him with Tyler's trauma as a victim is a common mistake because he replaces the "jock" archetype that previously tormented Tyler.
Understanding these nuances is the only way to truly grasp what the show was trying to say about trauma, cycles of violence, and the possibility of change. Tyler Down didn't kill Charlie; he saved himself, with a little help from the people he once thought were his enemies.
References and Further Context:
To understand the full scope of Tyler's character development, refer to the official Netflix character bios and the "Beyond the Reasons" specials that accompanied Season 2 and 3. These specials feature mental health experts discussing the real-world implications of Tyler’s arc and why the writers chose a path of recovery over a path of further violence. For those analyzing the legal or social ramifications depicted in the show, the character of Charlie St. George serves as a primary case study in "bystander intervention" and the dismantling of toxic social hierarchies within high school settings.
