Let me answer your points in order of complexity:
1) Thank you! I’m so happy you’ve been enjoying it.
2) It might be symbolic, but then again, maybe not. I haven’t considered that too deeply, but my instinct is to lean on no–simply because it would imply Roxy and Jane can’t ultimately “form bonds”, and I think the Nobles Prophecy only really applies to these kids insofar as their struggles in the session. If only because by the end they’re all positioned to start forming real bonds, and no cosmic destiny of emotional unavailability could stand before the might of Karkat Vantas’ relationship counseling anyway. They’ll all be fine.
3) I think I’m going to break up this longest post into four or so sections, and I’ll probably expand the Knights/Pages section to include Karkat and Tavros as well. Hopefully pointing to evidence from other Players will make this reading more convincing. I was also given some additional tidbits on Dave that I think are fun.
4) I think viewing selfishness as an inherently negative trait is a little simplistic. It definitely can be, don’t get me wrong–but then again, being selfless to a fault only turns you into a doormat, too, doesn’t it? And being selfless is only as virtuous an act as the people and ideas you decide to serve–after all, Gamzee’s a Passive player, too.
The way I read the Active/Passive divide is essentially this: Active classes generally work based off their own motivations and understandings. They may accept information from a source such as a Seer–Jade certainly does from Rose, just as Jake accepts Roxy’s provided secret. But what they do with that information is something they’ll decide on on their own for the most part.
Passive classes are likelier to act at the behest of others, and to advance other’s wills. Dave and John both spent most of their sessions either following orders from troll girls or following orders from Rose (or in Dave’s case, Jade too). Rose herself got direction from Doc Scratch as well as the Horrorterrors.
In contrast, you could read Jade as somewhat selfish, as I’m going to lay the case for in my next essay. She has patience and care for others, but she’ll tell someone if they’re bugging her if she needs to be getting shit done. And she doesn’t really accept much direction from anyone unless it’s in service to the plan she herself set up, as with Kanaya.
Are Jane, Dirk and Jake overly selfish? Maybe, yeah. Homestuck and Sburb both stress the need to find balance above all else, and Jake’s narrative definitely requires him to become less self-absorbed. In fact, at least one person posited to me that reaching that balance is the core challenge of each side of the coin, which I think is at least plausible.
But that balance is going to be different for everybody, and different depending on each relationship and situation. Life is complicated. In the case of Jake and Dirk’s relationship, Jake’s selfishness is healthy in extremity simply because it’s what Dirk wants too, and he wants it as intensely. Hopefully filling this role in each other’s lives would allow them to be more considerate and selfless to the rest of their friends, too. See what I mean?
