When Ed Speleers first stepped onto the Outlander set as Stephen Bonnet, he wasn't just another guest star. He was a hurricane. Most fans remember him as the man who turned a moment of rescue into a nightmare, but the journey of Ed Speleers Outlander Stephen Bonnet is way more complicated than just a simple "bad guy" arc.
Honestly, it’s rare to find an actor who can make you want to throw your remote at the TV while simultaneously leaning in to hear his next line. Speleers managed it. He took a character who was basically a sociopathic pirate and gave him a layer of charm that felt dangerous. It wasn't just about the scars or the stolen rings. It was about that unsettling Irish lilt and the way he looked at the world like it was a game he’d already won.
Why Ed Speleers was the perfect Stephen Bonnet
Casting Stephen Bonnet was always going to be a massive hurdle for the Starz production. In the books by Diana Gabaldon, Bonnet is this looming, terrifying presence who feels almost elemental. You need someone who can play the "gentleman" one second and a cold-blooded killer the next.
Speleers came into the show with a background that didn't necessarily scream "pirate king." You might remember him as the wide-eyed lead in Eragon or the handsome footman Jimmy Kent in Downton Abbey. But in Outlander, he shed that polished image completely. He leaned into the loucheness.
To get into the head of such a dark character, Speleers reportedly did some pretty specific prep. He actually built a playlist to capture Bonnet’s spirit. We’re talking Van Morrison, The Rolling Stones, and even Oasis. Specifically, "Cigarettes and Alcohol" by Oasis and "Lucky Man" by The Verve were his touchstones. He’d blast them in his hotel room to find that specific brand of arrogance and obsession with fate that defines Bonnet.

The psychology of the character
He didn't see Bonnet as a two-dimensional villain. In interviews, Speleers has talked about finding the "shades of grey." He looked into Irish history to understand the kind of trauma that might have molded a man like this. Bonnet wasn't born evil; he was forged by a world that gave him nothing.
That doesn’t excuse the horrific things he did—especially the assault on Brianna—but it explains why he felt so real. He had this twisted logic. Throwing children off a ship to stop a plague? To him, it was a practical business decision. That’s what makes him scarier than a monster; he thinks he’s the hero of his own story.
The moment everything changed: Season 4 vs Season 5
The introduction of Stephen Bonnet in the Season 4 premiere, "America the Beautiful," remains one of the most polarizing moments in the series. Jamie and Claire help him escape a hanging, only for him to rob them and murder their friend Lesley later that night. It was a gut-punch.
By Season 5, the showrunners took some liberties with the source material. In the books, Bonnet sticks around quite a bit longer, but the show decided to wrap his arc in the episode "Mercy Shall Follow Me."

This season showed us a different side of the character. Bonnet became obsessed with the idea of being a "gentleman" and a father. He wanted River Run. He wanted status. He even tried to "play house" with Brianna after kidnapping her. Seeing him try to learn table manners while holding a woman captive was peak psychological horror.
The death of Stephen Bonnet: Justice or Mercy?
The way Bonnet went out is still a hot topic in the Outlander fandom. He was sentenced to death by drowning—his absolute greatest fear. For a man who lived his life on the sea, the idea of being reclaimed by it was his ultimate nightmare.
But then, the twist.
As the tide rose to his chin, Brianna appeared on the bank with a rifle. She shot him in the head.

Was it an act of mercy? Some fans think so. She saved him from the slow, agonizing terror of drowning.
Was it about control? Others argue she just wanted to be the one to finish it. She took back her power. By being the one to end his life, she ensured he could never haunt her dreams again.
Speleers actually found out about his character's death in a pretty funny, roundabout way. He was on holiday with his family in Majorca when he got a call asking for a prosthetic fitting for a "bullet wound." He thought he might just be getting shot in the arm. Nope. It was right between the eyes.
What we can learn from the Bonnet era
Looking back, the Ed Speleers Outlander Stephen Bonnet era was crucial for the show's evolution. It pushed the Frasers into a new kind of conflict—one where the enemy wasn't an army or a political movement, but a single, chaotic force of nature.
- Villains need depth: A villain you can understand is always more terrifying than one you can't.
- Performance matters: Speleers’ ability to balance "charming" and "repulsive" is a masterclass in acting.
- Closure is complex: Brianna's choice to shoot Bonnet shows that "justice" doesn't always look the way we expect.
If you’re looking to dive deeper into the world of Outlander villains, comparing Bonnet to Black Jack Randall is a great place to start. While Randall was driven by a specific, focused sadism, Bonnet was driven by survival and a hollowed-out ego.
To really appreciate the craft Speleers brought to the role, go back and watch the Season 5 episode "Better to Marry Than Burn." Watch his eyes when he’s interacting with the gentry. You can see the insecurity behind the swagger. It’s those tiny details that made his version of Stephen Bonnet a character we’ll be talking about for years.
If you want to track the exact differences between the show and the novels regarding Bonnet's end, you'll want to pick up A Breath of Snow and Ashes and compare it to Season 5, Episode 10. The timelines are shifted, but the emotional weight remains heavy.
