These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Glitch is DG and Azkadellia's father. They both resemble him and the Queen was much closer to him than they ever show her being with Ahamo. There is a big portrait of him standing at her side, but none of her with Ahamo.
Ho Yay: Look, it's got Alan Cumming in it. And Glitch and Cain talk about dancing and Glitch tells Cain he makes him feel like girls at balls used to, and Cain makes him remember who he is by calling him "Sweetheart."
Magnificent Bitch: Azkadellia. She overthrew her mother, tricked DG into leading her to the Emerald, defeated the Tin Men and almost succeeded in her plan to trap the OZ in eternal darkness. The only reason she didn't is because she had a Heel-Face Turn, not because the heroes defeated her.
It runs in the family; while the queen is a more benevolent version of this trope, she counts with her plan to 'banish' Ahmaho, hide DG and implant memories and codewords to make her come back at the right time, as well as hiding the Emerald.
Everyone calls her DG. Everyone, all the time. Even her mother, in extreme times of crisis, only refers to her by initials. Because the incredibly obvious not so clever reference her name is would be ruined if they actually gave her a name. So in one of the films climactic scenes the queen can only say "Deeeeegeeeee!"
