So I assumed these comics were just going through the phase some series tend to where random cameos are introduced to sell issues without any satisfying payoff storywise, but I was dead wrong. 

Each issue does feature a different supporting character who attempts to help Luna and teach her about their perspective on the world, but it truly means something. Their wisdom leads Luna to reevaluate her seemingly wanted loneliness, and begin to realize the importance of relying on others. 

The last issue was powerful not only because Luna and her newfound friends all fought together as a group, but because of the growth that allowed that moment. It's difficult to grow up in a world where you feel like an outsider. Sometimes the easiest way to cope with it really is convincing yourself that you don't need anyone but you, even though that's destined to become self-destructive. 

Being the smartest there is doesn't mean you understand everything and don't need anyone, and it's relieving Luna is learning this lesson early on so she doesn't develop the same unhelpful and toxic behaviors that some of the other geniuses in the Marvel Universe have. I'm both proud and glad that she's is letting herself leave isolating mindsets behind, and hope she's able to gain an emotional intelligence to compliment and enhance her logical one.
