Called it that Dorothy would be the other half of the LGBT couple!
But with whom? The PR implies Ruby but Mulan makes more sense as the already established bisexual.
Surprise guest Ozma? Hey, Zelena mentioned Quadlings and killed Boq, so book references FTW! Also, last season gave us the six-leaf clover (a reference to The Patchwork Girl of Oz), so clearly the writers are familiar with the other books.
At what point was Mulan established to be bi? We only know she had feelings for Aurora. People just thought she had feelings for Phillip.
