One of the most notable things about queer characters in comics, especially in the heart of the superheroic mainstream, is their absence, at least on a textual level. Queer subtext, though? There's plenty of that, whether it's same-sex relationships that read as romantic, or in the use of mutants as a metaphor that can be applied to LGBTQ experiences.
Which brings us to Generation Hope #9, “Better”, by Kieron Gillen and Jamie McKelvie. It's not an issue explicitly about the LGBTQ experience, but it uses the mutant metaphor to tell a standalone story about real-life events that very much are.
