Ever since Susan Heyward stepped into The Boys as Sister Sage, fans have been fascinated by the character’s ability to control a room without ever raising her voice. In a series packed with explosive egos, violent outbursts, and nonstop chaos, Sister Sage quickly carved out her own space as someone even more dangerous: the smartest person in the room who knows it.
What makes the character so compelling, though, is that Sage rarely needs to be the loudest presence onscreen. Susan Heyward clearly understands that balance, and it’s part of why the character has connected with fans so quickly. Looking back on her time playing Sage, Heyward seems most drawn to the moments where the character quietly manipulates situations from the sidelines while everyone else spirals around her.
Some of her favorite scenes came early in the season during Sage’s interactions with Starlight, particularly when Sage was operating in secret and triggering immediate chaos while calmly observing the fallout. There’s something uniquely entertaining about watching a character who doesn’t need brute force because she already knows how events will play out before everyone else catches up. That subtle confidence became one of the defining traits fans latched onto almost instantly.

But according to Susan Heyward, Sage’s most powerful moments may come later in the season. Without giving away spoilers, Heyward teased that by the end of Episode 6, viewers see a version of Sage who finally feels free from the pressure and expectations that have been weighing her down. It’s a turning point where the character fully embraces her own confidence and power in a way audiences haven’t quite seen before.
In true The Boys fashion, though, one detail stood out to Heyward above everything else: the outfit. She admitted the costume Sage wears during that moment ended up being one of the most comfortable looks she’s worn on the show, which feels like a rare miracle in the superhero world where costumes usually look painful enough to qualify as endurance tests.
Outside of Sister Sage’s calculating brilliance, Susan Heyward also seems to have a deep appreciation for the absurd comedy that makes The Boys so addictive. When talking about other characters she enjoys watching, she immediately pointed to The Deep and the unintentionally hilarious confidence that follows him everywhere.
One small improvised line completely sold her on the comedy of the character. A simple adjustment that turned “It’s four karat gold” into “It’s four karat and gold” somehow made the line dramatically funnier because it perfectly captured The Deep’s complete lack of self awareness. For Susan Heyward, that’s what makes the character so entertaining. No matter how ridiculous things become, The Deep always carries himself like success is permanently one step away. It’s the kind of chaotic energy that balances out the colder, more controlled presence of Sister Sage.
At the same time, Susan Heyward revealed there are personal similarities between herself and the character she plays, especially when it comes to isolation. Like Sage, she admitted she sometimes disappears into her own head when life becomes overwhelming. Friends will check in wondering where she went because her instinct can be to pull away and process things alone.
Interestingly, playing Sister Sage actually reminded her how important real human connection is. In a world dominated by social media, online conversations, and endless digital noise, Heyward spoke about the importance of maintaining community and staying connected to people offline instead of becoming trapped in isolation.
That emotional honesty adds another layer to Sister Sage as a character. Beneath the intelligence, sarcasm, and constant calculating, there’s still someone carrying emotional weight like everyone else around her. Because this is still The Boys, Susan Heyward couldn’t leave fans without dropping at least one cryptic tease about what’s ahead. When asked for a hint about the finale, she offered just two words: “theme park.” Naturally, that only made fans more nervous.
Before wrapping up, Susan Heyward shared genuine gratitude for how quickly audiences embraced Sister Sage after her introduction into an already established world. Joining a series as massive and beloved as The Boys could have easily been intimidating, but Sage immediately became one of the show’s most talked about characters thanks to her sharp intelligence, unpredictability, and ability to command attention without ever needing to overpower a scene. And fittingly, the advice Susan Heyward chose to leave fans with felt completely in line with Sister Sage herself: read more.
For Heyward, reading isn’t just about intelligence. It’s about understanding people, expanding perspective, and finding deeper ways to connect with the world around you. Coming from the actress behind the most intelligent character in The Boys, it somehow felt like the perfect final message.
