If you grew up in the mid-2000s, you probably spent a significant amount of time staring at a glass of water, hoping it would bubble and freeze. It never did. But for Emma Gilbert, played by the then-unknown Claire Holt, it was just another Tuesday. H2O: Just Add Water wasn't just some low-budget Australian kids' show. It became a global juggernaut. It launched careers. It made the Gold Coast look like a literal paradise where magic was real and every teenager had a secret island hideout.
Claire Holt was the anchor of that trio.
While Cleo was the shy one and Rikki was the rebel, Emma was the responsible one. The swimmer. The one who actually followed the rules until she started turning into a mermaid whenever a stray raindrop hit her arm. Then, suddenly, she was gone. One minute she’s freezing things in the JuiceNet bar, and the next, she’s written out of the script with a vague "traveling the world with her family" excuse.
Fans were devastated. Honestly, some of us still haven't quite moved on.
The Reality of the H2O Just Add Water Claire Holt Departure
There’s a lot of gossip online about why people leave hit shows. Usually, it’s "creative differences" or some dramatic fallout on set. With Claire Holt, the truth is way more boring, but also way more interesting for her long-term career. She wasn't fired. She didn't hate her co-stars, Cariba Heine and Phoebe Tonkin. In fact, she and Phoebe are still best friends to this day.
The move was purely professional.
Claire had a chance to film Messengers 2: The Scarecrow. At the time, H2O: Just Add Water was heading into its third season. To do the movie, she had to skip the show. It was a gamble. You’re leaving a steady, high-profile gig for a horror sequel that might go nowhere. But for an Australian actor, the siren call of Hollywood is loud. Very loud. She took the leap.
The show tried to fill the void with Indiana Evans as Bella, who was great, but the dynamic was forever altered. The "Original Three" magic was broken. Without Emma, the group’s internal logic felt a bit wobbly. She was the strategist. The one who kept the secret from leaking to the entire world every five minutes.
From Mako Island to Mystic Falls
A lot of child stars peak at 17. They do the show, they do the mall tours, and then they disappear into the "where are they now" listicles. Claire Holt did the opposite.

If you look at her trajectory after leaving the fins behind, it’s a masterclass in staying relevant. She didn't just stumble into The Vampire Diaries. She earned the role of Rebekah Mikaelson, a character that was supposed to be a short-term villain but became so beloved (and feared) that she anchored a spin-off, The Originals.
Think about the tonal shift there.
She went from worrying about being splashed at a pool party to playing a thousand-year-old Original vampire who would rip your heart out if you looked at her brother the wrong way. It showed range. It showed she could handle the intense, often toxic, fandom energy of the CW era.
What’s wild is that she ended up reuniting with Phoebe Tonkin on The Originals. It was like a weird, dark Mako Island reunion. Instead of tails, they had fangs and hybrid curses. Seeing the two of them on screen together again felt like a wink to the fans who had been there since 2006. It proved that the chemistry they had as teenagers wasn't a fluke.
The Physical Toll of Being a Mermaid
We see the finished product—sleek tails, crystal clear water, and graceful swimming. The reality of filming H2O: Just Add Water was a nightmare for the actors.
Claire has mentioned in various interviews over the years how heavy those tails were. They weren't light spandex. They were custom-molded silicone and weighed around 40 pounds. Imagine being strapped into a 40-pound weight that binds your legs together and then being dropped into a tank or the open ocean.
It’s exhausting.
The girls had to train with free-divers to learn how to hold their breath for long periods while looking relaxed. You can’t have puffy cheeks or look like you’re gasping for air when you’re supposed to be a mythical sea creature. They had to swim with their eyes open in salt water. If you’ve ever tried that, you know it feels like someone is rubbing sand into your retinas.

Claire’s background as a competitive swimmer actually helped her land the role. She was comfortable in the water, which gave her a technical edge over other actors who were just faking it. She looked natural because, for her, the water was home. That athleticism translated later into her more physical roles in action and horror.
Life After the Limelight: The Claire Holt Brand
By 2026, the landscape of celebrity has changed. It's not just about the movies you make; it's about how you connect.
Claire has been incredibly transparent about her personal life, especially on social media. She’s talked openly about miscarriage, the struggles of motherhood, and the pressure to look "perfect" in an industry that demands it. This isn't the carefully curated PR fluff we see from some stars. It’s raw.
She’s built a massive following not by being Emma Gilbert, but by being Claire. She’s leaned into the lifestyle space, but with a level of authenticity that makes her feel like a friend rather than a distant star. She’s also a savvy businesswoman. She isn't just waiting for the phone to ring with the next script; she’s investing in brands and building her own ventures.
The H2O Legacy and the "Naur" Meme
You can't talk about H2O in the current year without mentioning the internet's obsession with the Australian accent. The "Naur" meme—poking fun at the way the girls said "No"—brought the show back into the cultural zeitgeist for a whole new generation.
TikTok is flooded with H2O edits.
People are rediscovering the show on streaming platforms. It has this nostalgic, sun-drenched vibe that feels like a safer, simpler time. Claire Holt is often at the center of these memes. She handles it with grace, often poking fun at herself. She knows that Emma Gilbert is the reason she has the platform she does today.
Some actors try to distance themselves from their "kid show" roots. They want to be taken seriously as "Artists." Claire seems to embrace it. She understands that for millions of people, she will always be the girl who could turn water into ice.

What You Can Learn from Her Career Path
If you’re looking at Claire Holt’s career as a blueprint, there are a few key takeaways.
First, don't be afraid to leave a "safe" gig if it means growth. Leaving H2O was a massive risk, but it prevented her from being pigeonholed as a children’s television actor.
Second, maintain your relationships. The fact that she and Phoebe Tonkin supported each other throughout their careers is rare in Hollywood. It helped both of them.
Third, adapt. When the industry shifted toward digital and social, she didn't resist. She used it to build a brand that exists independent of whatever character she’s playing.
Next Steps for Fans and Creators:
If you’re looking to dive deeper into the world of H2O: Just Add Water, start by revisiting the Season 2 finale. It’s arguably the peak of the original trio’s chemistry and showcases Claire’s best work on the series.
For those interested in the technical side of her career, look up the behind-the-scenes footage of the tail fittings. It will give you a newfound respect for the physical labor involved in "easy" fantasy acting.
Finally, follow her current ventures. She’s currently active in the wellness and parenting space, providing a much more grounded perspective than the typical Hollywood influencer. Whether she’s Rebekah Mikaelson or Emma Gilbert, Claire Holt has proven that staying power comes from being authentic, even when you're playing a mermaid.
