I agree with you on everything, and my MC always says Sage. But somehow I have mixed feelings about it.
That's where I see the reason why Jonah from Interlude could show up on B&R. Jonah is very open about his homosexuality and that is something that is missing on B&R. Through Jonah, Chad, Troy, Josy and Maya could also learn to be open about their homosexuality and bisexuality.
But that's just a thought of mine, nothing more.
In my opinion, it is correct that the MC told Josy about it because the MC can sell this situation as an affectation. Since Maya was not present and the MC would have told Maya later, it would have been intentional because the MC would have had time to think about it.
I agree that Josy doesn't have the resistance that Maya has. But Josy only refrained from telling her parents about her relationship with Maya because of Maya's experience. Therefore, Josy advises the MC not to tell Sage because of her own experiences.
I agree with you, so Maya would have suggested that too. But that would have been the wrong way to go. The right way to deal with something like this is pointed out by Jonah. Even Maya's problem is closer to a solution than before because she confided in Sage and Sage is okay with gay and bisexual unions.
Josy, of course, is unsettled because she learned from Maya what the consequences may be. Derek is much worse in this regard because he is prone to verbal diarrhea when under the influence of alcohol and this could quickly spread as a rumor.
