Zach Dempsey: Why Everyone Got the 13 Reasons Why Jock Wrong

High school dramas usually love a good trope. You've got the nerd, the rebel, and of course, the star athlete who’s probably a jerk. When we first met Zach Dempsey in 13 Reasons Why, he fit that "cocky jock" mold perfectly. But honestly? As the seasons dragged on, he became one of the most confusing, frustrating, and strangely relatable characters on the show.

He wasn't just some villain. He was a guy stuck between wanting to be a "good person" and needing to fit in with a group of people who were objectively terrible.

What Really Happened With Zach Dempsey and Hannah Baker?

Most people remember the tapes. Zach was on Tape 4, Side A. In the first season, it seemed like he was just another bully who stole Hannah’s anonymous "notes of encouragement." It felt petty. Cruel, sure, but small-scale compared to what others did.

But then Season 2 dropped a massive bomb.

It turns out Zach and Hannah had a full-blown secret summer romance. They traveled together, hung out, and even lost their virginities to each other. This changed everything. It made his actions in Season 1 look way worse. He wasn't just a random classmate being mean; he was someone who actually knew her, loved her, and then chose his "jock" status over her once school started.

He was ashamed to be seen with her. That’s a heavy thing for a teenager to process.

The Note He Never Threw Away

One of the biggest "gotcha" moments in the series involves a letter. Hannah claimed Zach threw away a heartfelt note she wrote him. In reality, he kept it in his wallet the whole time.

This is where the show really started playing with the idea of "subjective truth." Hannah thought she saw him toss it. She felt rejected. Zach, being a coward, didn't correct her. He carried that piece of paper around like a physical manifestation of his guilt.

The Downward Spiral: Why Zach Turned Reckless

If you watched Season 4, you know it was a total mess for Zach. Some fans hated it. They felt the writers just gave up on him and turned him into a drunk who made terrible choices.

Think about what he was carrying, though:

• He watched his friend Bryce die (and honestly, he kind of helped).
• His football career was dead because Bryce broke his knee.
• His dad was gone, and his mom was putting immense pressure on him.
• He was basically an accomplice to a murder cover-up.

Most kids would crack. Zach didn't just crack; he shattered. He started drinking, doing drugs, and even brought an escort to prom. It was dark. He became the guy who just didn't care anymore because he felt like his "good guy" identity was a lie anyway.

Zach Dempsey’s Ending: Redemption or a Rush Job?

In the series finale, Zach gets a weirdly optimistic ending. He’s offered a coaching job at Liberty High, but he turns it down. Instead, he decides to go to college to study music—specifically singing and guitar.

His mom thinks he’s going for the violin (the "respectable" path), but he finally chooses something for himself.

Is it a satisfying end? Kinda. It feels a bit fast. We spent ten episodes watching him destroy his life, and then suddenly, he’s okay because he got into music school? It's a bit of a stretch. But in the world of Liberty High, where characters are constantly dying or going to jail, "going to college to play guitar" is about as happy as it gets.

The Ross Butler Factor

We can't talk about Zach without mentioning Ross Butler. He brought a lot of nuance to a role that could have been very one-note. Butler has been vocal about wanting to play "all-American" roles that aren't defined by his heritage. By making Zach a complex, flawed, and occasionally heroic character, he definitely pulled that off.

Key Insights: What We Can Learn From Zach's Arc

If you’re looking for the "point" of Zach Dempsey, it’s basically a study in peer pressure and the cost of silence. He wasn't the one who raped anyone. He wasn't the one who pushed Bryce into the water. But he was there. He knew. And he stayed silent to protect his own skin.

Practical takeaways from his story:

• The "Bystander" is never truly innocent. Zach’s guilt stemmed from what he didn't do as much as what he did.
• Grief isn't linear. His Season 4 spiral was a realistic, albeit extreme, look at how trauma can manifest as self-destruction.
• Communication is everything. If Zach had just told Hannah he liked her in public, or told the truth about the note, things could have been vastly different.

If you’re rewatching the series, keep an eye on Zach in the background of Season 1. Knowing what we know now about the "Summer of Hannah," his facial expressions in those early episodes take on a completely different meaning. It’s worth a second look just to see the cracks in his armor before everything finally fell apart.
