What is the purpose/true potential of "FrayMotifs" in regards to class/aspects? We've seen them in use throughout [S] Collide, and even a time when Dave and Jade used "Adagio Redshift" on Bec Noir way earlier in the story. I find them to be interesting, but I feel like there were a few loose ends to the concept. Like why it's music based, or how opposite aspects interact with each other.

Aspects don’t have Opposites, they have Complementaries, so they would definitely not cancel each other. We actually see Void and Light interacting in Collide, and they only play off of each other and amplify each other nicely. Fraymotifs are just combo attacks, though, the whole music theme is because a lot of Homestuck itself is music and theatre themed, like. A lot of the Quests and Tools and the Scratch Constructs, are related to Music in some way or other. They’re cool abilities, but they’re just kind of that, combo abilities.
