EB: i'm sorry karkat, i didn't realize we screwed up so bad.
CG: ALRIGHT WELL
CG: I WASN'T EXPECTING YOU TO MAN UP AND APOLOGIZE FOR IT, SO OK I'LL GIVE YOU CREDIT FOR THAT. [...]
EB: i just feel kind of bad i fell asleep, i don't know what came over me. [...]
CG: HEY, INOPPORTUNE NAPS HAPPEN IN THIS GAME.
I love that even at this early stage, Karkat keeps forgetting that he's supposed to be 'mad' at John.
CG: I MANAGED TO STAY AWAKE FOR SEVERAL WEEKS STRAIGHT, I DIDN'T WANT TO LET MY GUARD DOWN FOR A SECOND. [...]
CG: AFTER IT WAS ALL OVER, AND WE RETREATED IN FAILURE
CG: I FOOLISHLY DID.
CG: AND THAT'S WHEN I SAW HIM. [...]
CG: JACK.
Poor Karkat probably thought he was back from Alternia with a vengeance - which would be doubly painful, since Karkat liked Jack, and was completely against Exiling him.
CG: HE WAS WEARING A RING I DIDN'T RECOGNIZE, CERTAINLY NOT ONE BELONGING TO OUR QUEENS. [...]
CG: HE WORE IT ON HIS ONE HAND, WHICH WAS COVERED IN OUR MUTANT BLOOD.
If Jack had got that blood from the troll session, we'd have a pretty good idea who it belonged to.
But Jack arrived with that blood. It came from the human session, and could have belonged to anyone there.
The narrative is giving it a lot of focus, though - even in Jade: Enter, the camera kept lingering on Jack's arm. This is 'important' blood, which will be shed in a pivotal moment later on.
Move over, Bilious Slick - there's a new god in these parts.
CG: I PRETTY QUICKLY DETERMINED THAT HE WAS FROM YOUR SESSION, NOT OURS. [...]
CG: AND I WAS SORT OF RELIEVED
CG: RELIEVED BUT ALSO ENRAGED
CG: I'M SURE YOU KNOW THE FEELING. [...]
EB: not really.
This is how you can tell John's not a programmer yet.
Get back to me when you've been debugging for two hours, and you realize you missed a free(). Then you'll know exactly what Karkat is feeling.
CG: I'VE GOT TO REWIND THE TAPE ON THIS CLUSTERFUCK AND FIGURE OUT WHAT WENT WRONG.
EB: yeah, i should get going too.
EB: my friend is pestering me, and i doubt she likes to be kept waiting.
EB: (she is sort of the bossy type!)
CG: WHY WOULD I CARE ABOUT YOUR DUMB HUMAN FRIEND AND HER PETULANT, MEANINGLESS DEMANDS.
'What went wrong' is the girl who's messaging John right now.
I cannot wait for Karkat to figure out who actually caused the Mistake, and confront Vriska directly. It'll be cathartic, I think, for his rage to be directed to someone who's deliberately responsible for their problems.
Karkat is no match for Vriska, of course - but he doesn't necessarily have to be. He's a leader, and once he starts yelling about who actually got them trapped in the Veil, the other trolls are sure to take his side, no matter how annoying he is.
Vriska is extremely resourceful, but if Karkat rallies all the surviving trolls against her, her victory is far from guaranteed. She'll be up against Terezi, Kanaya and Sollux - not to mention Feferi, who's recently proven she's not as much of a pushover as you'd expect.
This is all hypothetical, of course. Before we can talk about Vriska's plans, we need to understand what the fuck she's playing at here. It's possible that this was ultimately for everyone's benefit - but I think it's more likely an act of hubris. Vriska seems bent on fighting Jack directly, so I think she's messing with his timeline to make him vulnerable in some way. That's not how the Alpha works, Vriska!
