Carmen and Seri are lesbians. Brandy is bisexual. All of the girls are queer, but what exactly does Candace identify as? I know from writing the comic that Candace is queer, but I could have done a better job of exploring Candace's sexuality in Grunge. It is only touched on at the end of the game.
Candace’s experience is most like that of my own: she spent a long time in a monogamous relationship (which also made her pretty miserable towards the end) and after ending it, realized that she didn’t know as much about herself as she thought she did. Further, she realized that she had skipped a lot of opportunities to learn about herself when she was younger. Her newfound freedom leads Candace to question her sexuality.
If you chose to go to Brandy’s house in chapter two, Brandy comes out as bisexual, and reveals that she is very attracted to Candace, but would never say anything about it. In a way, Candace and Brandy’s relationship is more complicated than Carmen and Seri’s, because Michael is present. You might think that Brandy should be the catalyst for getting their relationship started, but she is not. While the girls all rib on Michael, he is their mutual friend, and even Brandy wouldn’t want to overstep her boundaries and ruin someone else’s relationship intentionally. Plus, Brandy (at first) isn’t so deeply in love with Candace that she would seriously pursue her. The Brandy that we first meet in Grunge is uncomfortable with monogamy, mostly because she doesn’t want to be tied down to anyone. Brandy can be monogamous, but she has to feel really comfortable with another person in order to be in a serious relationship.
Candace and Brandy do become canon. :-) This is something that I hope to explore in Grunge’s companion story, title TBD.
So Candace doesn’t come out until her mid to late 20s, but I don’t see that as a bad thing. Candace didn’t actively suppress her sexuality or feelings for women; she just hadn’t really thought about her feelings for women. Candace eventually comes to the understanding that she is pansexual, as she is most comfortable with that label. Everyone comes out at different points in their life. Some take a little longer than others, and that’s okay, and doesn’t make their identity any less valid.
