I mean, look at all the heart and void players weve seen through out the comic. nepeta and equius are the face of moirails everywhere, dirk and Roxy have the closest bond out of all the the human kids. the heart and void aspects seem to just fit together for some reason

Oooh, THAT kind of ties! I mean it may be a coincidence- Meulin and Horuss, for example, don’t seem to quite think much of each other, and they’ve only recently become Moirails because she wanted to emulate the Meowrails. Hmm… Maybe that’s it? Heart Players have a strong personality, and tend to easily influence Void Players, who are more malleable?
