Elphaba & GlindaElphaba and Glinda have a considerable amount of Ho Yay in both the musical and books. Word of God has said "something" was going on between them in a romantic sense, but he never clarified on it after that. Many of the musical cast (including the original Elphaba, Glinda, and Fiyero) have said that the musical is a love story between Elphaba and Glinda and that they would have dated each other if things had turned out a little differently.
- Their duet at the end of the musical is arguably more romantic than any other duet in it. "For Good" sounds so much like a love song, especially the description of nature that was compared to the fact that Glinda and Elphaba knew each other and changed for the better.
- Hell, their first duet is probably the walking definition of Slap-Slap-Kiss romance ("My pulse is rushing / My head is reeling / My face is flushing / What is this feeling?" No Elphie, it's not loathing — it's lust.) Word of God is they tried to find every sappy romance lyric, put it into the song, and subvert it; so it's very much intentional.
- It doesn't help that the first time we hear the Wicked 'Unrequited Love' tune, it's when Glinda tells Elphie she's beautiful. Elphie's weirded out and runs off. Is it just me or is Glinda a teensy bit wistful as she sings about E protesting her disinterest?
- And it gets even more blatant during the Emerald City sequence ("One Short Day / Defying Gravity"). Two... best... friends, sharing one wonderful day. Riiight. By the time Elphie sings "Kiss me goodbye, I'm defying gravity," the Yay is about as thick as poppy fumes. "Together we're unlimited..."
- In "Thank Goodness", Glinda sings wistfully about how she feels like she ought to be thrilled to be marrying Fiyero, but she can't help but think of "a couple of things that got lost/and there are bridges you cross you didn't know you crossed until you've crossed..."
- This is subtler but definitely intentional in the original novel; by the end, Maguire's done all but come out and say that Glinda's been in love with Elphie ever since their schooldays. (Whether Elphie ever felt anything reciprocal is extremely open for debate, since iirc none of their scenes together are from her POV.)
- Glinda never had a romance with Fiyero in the books, and it's explicitly stated she married her husband for money and that she never had sex with him. When you put this together with her relationship with Elphaba, it comes that she's supposed to be gay.
- Their parting is somewhat bizarre in that it's significantly more romantic that anything between up to that point. Rather like a Now or Never Kiss.
"You'll be all right," Elphaba said, "now you're a seasoned traveler. This is just the return leg of a voyage you already know." She put her face against Glinda's and kissed her. "Hold out, if you can," she murmured, and kissed her again. "Hold out, my sweet."
The driver clucked the reins, and pitched a cry to leave. Glinda craned her head to see Elphaba drift back into the crowds. For all her singularity of complexion, it was astounding how quickly she became camouflaged in the ragamuffin variety of street life in the Emerald City. Or maybe it was foolish tears blurring Glinda's vision. Elphaba hadn't cried, of course. Her head had turned away quickly as she stepped down, not to hide her tears but to soften the fact of their absence. But the sting, to Glinda, was real.
- The Les Yay extends to the sequel book, where Glinda still seems very upset over Elphaba's death. When Liir, Elphaba's son, brings her Elphaba's cape she refers to her as "My Elphie".
Crope & Tibbet
- Crope and Tibbet are always hanging around each other, seem really affectionate and just come across as...well gay. Tibbet has sex with a male tiger and dies of an unspecified disease and Crope winds up in the theater establishment.
Rain & Tip
- Rain has some when it's revealed that her semi-romantic interest Tip is actually Ozma Tippetarius.
