Dorothy/Ruby was wasted. Had there ever been an episode that even remotely hinted that Ruby was lesbian or bi? And due to her not being on the show except for brief guest appearances, it kind of killed the chance of them doing more with that. If they wanted Dorothy to have a lover they should have introduced Ozma...it's not canon that they are lesbians, but they are incredibly close in the books, to the point of kissing on the lips and pining for one another. Red was just too out of the blue (pun sort of intended).

As for Mulan, she could find love with either male or female, or maybe she's decided that she's fine as she is for now. Not everyone needs someone romantic in their life to be complete. Same for Merida.
