Meet the New and Returning Faces You'll See in Season 3 of Sex Education

Butterfield returns as Otis, the often-awkward teenager at the center of the story.

Following her recent run on The Crown as Margaret Thatcher, Anderson is stepping back into the shoes of Dr. Milburn, a sex therapist and loving (if sometimes embarrassing) mom to Otis.

Mackey is back as Maeve, Otis's pal, "therapy clinic" partner, and, now, possible love interest.

Although her character breaks up with Otis in season two, Allison is back for season three, with Ola continuing to play a role in the group of friends.

Gatwa's character, the openly gay Ghanaian-Nigerian teen Eric, has become a fan favorite, and it's no surprise he's back for the new season.

Reynolds will be back for a third season of bringing quirky Lily to the screen.

Wood is bringing back Aimee, the popular girl who's crossed over to hang with the decidedly less-cool main group of friends.

Williams-Stirling will reprise his role as Jackson, Moordale's swimming star.

Following something of a villain-to-hero arc, Swindells's Adam will return in season three.

Persbrandt is back as Jakob, Ola's dad and the handyman who falls for Jean.

Petrie is back for a third season of playing headmaster Michael Groff.

Saleh, a singer-songwriter, will join the cast in season three as Cal, a nonbinary student who clashes with the new headmistress at Moordale.

Lucius Malfoy himself, Isaacs, is slated to appear in season three, playing Peter Groff, Michael's "more successful/less modest" brother.

The Girls star is taking over as headmistress at Moordale, playing Hope, a former student at the school who has some big ideas.

Indra Ové joins the series as Anna, the foster mom of Elsie Wiley. For those of you who may not recall, season two of Sex Education ends with Maeve's mom, Erin, being taken away after Maeve notices that she's using again. As a result, Maeve's half-sister, Elsie, has to be taken into foster care.

Chinenye Ezeudu will be back in season three, continuing her role as Viv. Her character is introduced in the show's second season, and she quickly becomes good friends with Jackson (played by Kedar Williams-Stirling) after helping him with his career decisions.

Simone Ashley, who's recently been confirmed to join Bridgerton's upcoming season, will in fact be returning to Sex Education for season three. Continuing her role as Olivia, one of Moordale High's resident mean girls, we're looking forward to seeing how her character changes.
