Heartstopper Season 3 Cast and Character Guide: Everything You Need to Know

In Heartstopper Season 3, things are about to change for Charlie (Joe Locke), Nick (Kit Connor), and all their friends. As Tara (Corinna Brown) and Nick agree in the trailer, everything is “a lot” right now for your favorite British pals. Some of them are starting sixth form and considering university ahead.

Heartstopper Season 3 will feature some new faces joining the cast of friends, family members, and teachers from Truham and Higgs. Here's a guide to all the characters you can expect to see in the upcoming season.

Charlie (Joe Locke)

Charlie begins Heartstopper Season 3 determined to say “I love you” to boyfriend Nick. As creator Alice Oseman tells Tudum, “They don’t need to say it for us to know that they are in love. But when you are a teenager, I think saying the words ‘I love you’ holds so much weight. It’s a big declaration of commitment to someone.”

On top of his intensifying relationship with Nick, Charlie is also on the verge of a very important mental health journey. Locke, along with Oseman and the rest of his cast, worked on telling Charlie’s story during Season 3 rehearsals.

“Everyone has their own personal experiences with [mental health] and with the people in their lives who’ve dealt with that,” Locke told Tudum last year during a visit to Heartstopper’s England set. “So I think it’s a very personal thing, what you take from that and put it into the character.”

You can also see Locke as the mysterious character Teen in Marvel series Agatha All Along.

Nick (Kit Connor)

Nick, just like his boyfriend Charlie, is also on the road to “I love you.” But the rugby player also has a lot of other pressing issues on his mind.

“Nick is also very ready to say I love you. I just don't think it’s really crossing his mind quite as much at the beginning of Season 3 because he is very concerned for Charlie,” Connor tells Tudum. “He feels like Charlie’s holding something back from him and that is a worry for Nick.”

Despite the emotional obstacles ahead, Nick is still headed towards some growth. “[He gets] more comfortable with himself when Charlie isn’t there. And that’s an important topic I think as well,” Connor says.

Connor is one of Heartstopper’s most seasoned young actors. He got his first on-screen credit in 2013 in an episode of Chickens and has since appeared in many TV shows and movies, including The Guernsey Literary and Potato Peel Pie Society, Rocketman, and His Dark Materials. He made his Broadway debut with Romeo + Juliet, alongside Rachel Zegler.

Elle (Yasmin Finney)

In Heartstopper Season 1, Elle enters Higgs as the new girl — and without her longtime pals back at Truham. Along the way she becomes close friends with Tara (Corinna Brown) and Darcy (Kizzy Edgell). And now she’s making even more pals at her new art school.

Beyond her friends, Elle’s most important relationship is with her BFF turned boyfriend, Tao. In Season 3, we explore their maturing relationship, and how Ellle feels exploring her sexuality as a trans girl.

“Season 2 was a very adorable. It’s her first kiss, it’s very romantic,” Finney said last year on set. “But this season, it’s more about being an adult … You really see Elle become that strong woman that she’s always been — and the growth.”

Finney is also a model and popular TikToker. She earned more than 1.9 million followers by posting beauty tutorials, dance challenges, and more personal videos. Since joining Heartstopper she has gone on to star in Doctor Who.

Tao (William Gao)

Tao is the “token straight friend” in Heartstopper and part of Charlie’s support system at school. Tao is protective of all of his loved ones, including Charlie, his girlfriend Elle, and, even now, Nick. In Season 3, Tao is learning more about what drives him.

“When you’re growing up, there’s a lot of things you’re not conscious [of about yourself] and insecurities that come through as certain [behaviors],” Gao said on set. “Tao is discovering those and becoming aware of those feelings.”

Gao is making his on-screen debut as Tao, but he’s not new to the art of performing. Gao has worked with the UK’s National Youth Theatre, an organization whose alums include Helen Mirren, Daniel Craig, and Chiwetel Ejiofor. And as a musician, he’s released an EP with his band, Wasia Project.

Isaac (Tobie Donovan)

Isaac is another member of Charlie’s close friend group. He’s always there for his friends and is careful not to take sides. Affable and a great secret keeper, Isaac can rarely be found without his head in a book. In Season 3, he’s continuing his journey as
