Disney Channel series “Andi Mack” will reveal that one of the main characters is gay in the upcoming Season 2 premiere.

The second season premiere depicts one of Andi’s two best friends, 13-year-old Cyrus (Joshua Rush), as he’s beginning to realize that he also has feelings for Andi’s crush, Jonah Beck. In subsequent episodes, Cyrus begins to understand himself and grapples with how to tell his new girlfriend. He finds he can count on supportive friends Buffy and Andi who, as teenagers, are also on a journey to self-discovery. This realization begins an important part of his journey to self-discovery as a gay individual and ultimately, his self-acceptance. The story arc marks a first for Disney Channel, as it will be the first time the channel has depicted a character’s journey to discovering they are gay.

The storyline was met with praise by LGBTQ groups, who were allowed to screen the premiere in advance.

“With more and more young people coming out as LGBTQ, ‘Andi Mack’ is reflecting the lives and lived experiences of so many LGBTQ youth around the country,” said Sarah Kate Ellis, President and CEO of GLAAD. “Television reflects the real life world and today that includes LGBTQ youth who deserve to see their lives depicted on their favorite shows. Disney has been a leader in LGBTQ inclusion and there are so many young people who will be excited to see Cyrus’ story unfold.”

The season premiere will also see Andi trying to coax her parents Bex and Bowie to get married, all while she awkwardly sorts out her feelings for Jonah.

“‘Andi Mack’ is a story about ‘tweens’ figuring out who they are; Terri Minsky, the cast and everyone involved in the show takes great care in ensuring that it’s appropriate for all audiences and send a powerful message about inclusion and respect for humanity,” a spokesperson for Disney Channel said in a statement to Variety.

The series stars Peyton Elizabeth Lee as Andi, who found out in Season 1 that the person she thought was her older sister is actually her mother. In addition to Lee and Rush, the series also stars Sofia Wylie, Asher Angel, Lauren Tom, Lilan Bowden, Trent Garrett, Stoney Westmoreland, and Emily Skinner. It was created and is executive produced by Minsky, who previously created the Disney series “Lizzie McGuire.” Michelle Manning is also an executive producer. Phil Baker is co-executive producer. Horizon Productions produces.

The one-hour Season 2 premiere of “Andi Mack” will air on Oct. 27 at 8 p.m. ET/PT on Disney Channel.
