I'm sorry to assume I feel the same way you do.
She apologized to the MC herself so she could get the MC to tell her. Josy won't just tell someone, but someone could make her tell, just like she made the MC tell her. Josy talked to Sage and said something about Maya's problem. Josy only made hints, but in doing so she gave Sage the information that allowed Sage to elicit pretty much anything from Maya. Sage got Maya to tell more than she might have wanted to. Maya herself tells Josy that Sage knows everything now.
So why can't Josy be made to reveal the secret the MC entrusted to her?
Should be understandable, right?
The others are just theory, which could be possible, but doesn't have to be. It occurs to me that someone long ago used the theory of two pairs of red sneakers to write about a gay relationship of Chad and Troy, the same can happen with a tennis racket and sunscreen.
