I’ve recently set up a personal headcanon rule that no more than 8 of the show’s ~800 existing characters (equaling a single percent) are gay or bi, I guess to make sure the word “minority” maintains its meaning. Seeing how Lyra/BonBon and Holiday/Lofty are already canon, that leaves 4 right away, so the ones I’ve picked are…
*Applejack and Coloratura - Yeah, this is my AJ ship. In spite of the nature of their relationship, I see AJ not being all that comfortable outright identifying herself as a member of that crowd, mostly cause Coloratura’s the only one she really had these kind of feelings for, and she’s too faithful to potentially devote herself to anyone else that way.
*Trixie - My headcanon is that she’s certainly attracted to Starlight, but at the same time she’s gathered that Starlight only likes her as a friend and would rather not make things weird by admitting her feelings. I can see her engaging in some sort of service to find another fish in the ocean.
*Sunset - I know full well her being bi was just Dumbledoring, but ah what the hell.
