In Once Upon a Time Season 5, viewers are reminded that love knows no boundaries. In “Ruby Slippers,” the show introduces its first ever LGBT love story and it is sealed with True Love’s kiss.

Mulan (Jamie Chung) and Ruby (Megan Ory) are running through the woods in Oz to track down Ruby’s wolf pack. The duo encounters Dorothy’s dog, Toto. Ruby attempts to show Toto that she’s trustworthy, but then she ends up scaring the pup away. Ruby helps an angered Dorothy (Teri Reeves) locate Toto by using her wolf sense to track the pup. They run into Zelena who has held Toto captive. Zelena promises to return Toto if Dorothy surrenders her magical silver slippers to her.

Mulan, Dorothy, and Ruby team up to brew a spell that will knock out Zelena. During this time, Dorothy and Ruby spend some time together, talking about similar family problems. As they go deeper into the conversation, the two give each other nicknames and even showed a bit of sexual tension.

Ruby seeks advice from Mulan who has some experience in this department. According to Mashable, Mulan developed feelings for Princess Aurora in previous episodes. Unfortunately, Aurora did not share the same feelings and she ended up with Prince Philip.

In Sunday’s episode of Once Upon a Time Season 5, Ruby tells Mulan that she’s never had feelings for anyone the way she has for Dorothy.

“Don’t make the same mistake that I did. Don’t wait until it’s too late to tell someone how you feel,” Mulan tells Ruby. Just when Ruby gathers up the courage to express her feelings for Dorothy, they discover that she has gone.

“True Love’s kiss has been a staple of this show since the beginning. This past Sunday’s episode was just another example of how in a fairy tale, as in life, love is love,” showrunners Adam Horowitz and Eddy Kitsis said about the LGBT love story, via Hollywood Reporter.

As to what we can expect from Dorothy and Ruby’s storyline, Horowitz adds it will be as  “exciting, emotional and heartfelt as any other love story.”
