the showrunner has been saying that since before the renewal was announced. it's basically "it's ok disney didn't want a gay show on their children oriented streaming service because now we can do less kid friendly things". and i'll believe it when i see it, because at the end of the day, the show is still under disney.
i expect it to be not that different from runaways, a disney owned show that aired on hulu. you'll get some more intimate moments with the non straight characters, but not much different than it would've been if this were airing on abc, because it's still a show aimed at younger audiences
