A major character on The CW’s DC TV universe is about to come out as gay.

“One of the characters on one of the shows [‘Arrow,’ ‘The Flash,’ ‘Legends of Tomorrow’ and ‘Supergirl’] is going to be exploring their sexuality and coming out,” executive producer Andrew Kreisberg said (via Entertainment Weekly) at The CW’s panel at the Television Critics Association’s press tour on Thursday. “We’re very excited about that.”

While Kreisberg and other producers declined to reveal the identity of the character, which show, and whether they were male or female, Greg Berlanti said (via TVLine) after the panel that “it’s not a new character that’s been added” — and that it’s not someone from “Arrow” or “Legends of Tomorrow,” which already feature a gay (Echo Kellum’s Curtis Holt) and a bisexual character (Caity Lotz’s Sara Lance).

“It is a significant character,” Berlanti further teased. “The only reason we [don't want to say who] is we really want the audience to enjoy the character development and not necessarily be ahead of the storyline.”

Since Berlanti mentioned that the character “hadn’t been gay” when the show started, a lot of fans think that it might be “Supergirl’s” Winn Schott (Jeremy Jordan).  Although Winn had a pretty serious crush on Kara Danvers (Melissa Benoist) in Season 1, some viewers think that making the character gay would be a great move to kill the love triangle between Winn, Kara and James Olsen (Mehcad Brooks).

Initial buzz also favors Kara’s sister Alex Danvers  (Chyler Leigh), who appeared to be intentionally distancing herself from admirer Maxwell Lord (Peter Facinelli) during the show’s freshman run. A number of fans speculate that Alex will be the romantic interest of new character Maggie Sawyer (Floriana Lima) — a lesbian detective for the National City Police Department who takes a special interest in cases involving aliens.

Whoever that mystery character is, the decision to make him/her gay is part of Berlanti’s attempt to make the network’s DC TV universe more gender-inclusive.

"I [have always] wanted to contemporize these comics that I loved growing up and have them reflect the society that we live in now," Berlanti told The Hollywood Reporter last May. "It's still about working in some of those very real qualities so that everyone feels represented."
