Speaking to TV Guide at the GLAAD Awards, Liz Brixius explained that she is happy that the characters' sexuality is not a big issue in the series.
"It doesn't feel like we're soldiers for anything anymore," she said. "We're just here telling stories that incorporate gay people in organic ways, and that's all I ever wanted.
"I didn't want to break ground, I just wanted to be able to coexist with the rest of the world. And a show like this and a group like GLAAD allows that."
Brixius also dropped hints about an upcoming storyline involving Coop (Peter Facinelli).
"The bedrock of Coop's family - the gay mothers - there's upheaval," she said. "We're going to have some problems with Coop and his gay mums and it destroys him, because parents are parents whether they're gay or they're straight."
