WV wasn’t a warrior. He was a leader. He believes ‘you were never cut out to be a leader of men’ after his failure, but the responses of the other carapacians show that they believed in him and were willing to follow him. That will probably come back in some way. After all, he’s still showing bits of that Blood-like tendency: everyone likes him and considers him a friend, he governs Can Town which represents inter-species cooperation, etc. He believes in democracy and fairness. I can definitely see him taking some sort of support/motivation/leadership role in the endgame.
But most of all, the WV: Dream sequence shows that he doesn’t want the ring. He dreams of turning into Jack and slaughtering his own followers. This shows his guilt over what happened in WV: Rise Up/Descend, but I think it also shows his fear that the power of the ring will corrupt him. I mean, why not go for the whole LOTR parallel? I can’t see WV willingly putting on the ring, considering all it represents to him. But I can see him taking it and being the one wise enough not to use it, doing his part to end this cycle of violence once and for all. After all, monarchies transition from one ruler to the other through right of inheritance. Democracy is where you have a choice.
In his dream, I don’t think it’s too far from the truth to suggest that WV was equating the ring-gained attributes — that bloody one-armed winged dog-headed appearance — with his failure as a leader. He envisions Blood spreading from his arm into destructive twists of power that destroy the united, black-and-white army in front of him, wiping them out just as surely as Jack Noir did the army he had led himself. As far as WV is concerned, the deaths of all the soldiers he led was his own responsibility: WV believes he is the one who got them killed, as badly as if he’d donned the ring and performed the execution himself.
As you’ve pointed out, the Ring of Orbs Fourfold represents one hell of a lot more than some fancy destructive powers. The ring symbolizes Blood: The utmost responsibility borne by leaders, the power of commitment and unity. If performed in sound mind, wearing the ring wouldn’t be an act meant simply to grant dueling power to WV. Rather, it would be a rebuke of the fear he expressed in his dream, the fear that his leadership could only lead others to their deaths. He wouldn’t be accepting a role as “Vindicator”; he’d be accepting a role as leader, both entrusted with the ring by others and trusting in himself, in his ability to unite and lead.
WV almost certainly will lead other carapaces again at some point, and almost certainly also will put on the White Queen’s ring (the one PM’s currently wearing) once he overcomes the insecure dejection he’s developed with his true role.
But I can’t really tell you the when, where, or why of either. It’s his destiny, but I don’t know where it fits.
EB: also, another thing about him… EB: he has the queen’s ring!
GG: thats great! john you have to get that ring from him!
EB: i’ve tried! i asked him politely for it and everything.
EB: but he is very protective of it!
GG: that is a problem!
EB: actually, i think it’s ok.
EB: i think he is supposed to keep it.
GG: you do?
EB: yes. once i saw something in the clouds.
EB: it was hard to tell what was going on, but i saw him!
EB: im pretty sure it was the future, and he had the ring, and…
GG: and what?
EB: and then the cloud stopped showing me.
EB: but i am pretty sure that some day…
EB: he will have to wear it!
EB: so i think i will just let him keep it.
EB: for some reason, i trust him.
GG: ok john…..
GG: i trust you
GG: so i will trust in your trust in him
EB: yeah, trust all around!
GG: im going to be a supportive piece of shit all day and fall down all this trust!
EB: how trustworthy do you even have to BE to CONFIDE in someone like that.
Blood is trust, and WV is an Heir of Blood! He may be dejected and wandering from his role for now, afraid that his leadership can only lead to suffering, but that doesn’t mean that he isn’t meant to overcome that someday, wear the ring, and lead an entire people to victory.
I am always hesitant to make plot predictions about Homestuck, because it so frequently surprises everyone. So really I don’t know what will happen. However, no matter the ring’s association with Blood, it still strikes me as a symbol of monarchy and the hereditary ‘right to rule’ Thus, WV with his Mayor status and love for democracy would not want to use it. I also can’t see PM wanting to relinquish it until she believes her duty is fulfilled. Really the only way I can see WV dealing with the ring is protecting it or perhaps even destroying it, because its greatest power so far has been destruction and he stands for creation.
I might be wrong, but that’s what I’m getting from his character right now and hey, being wrong about Homestuck is half the fun.
