Read this and read into the phrasing very carefully.
John’s instructions are to go back to Game Over and do something that lets him gather all the human kids and take them to the masterpiece - but not the kids living on Earth C (CANDY), the kids from the Game Over timeline (MEAT) - they’re all “completely different people” from what seems like an eternity ago.
More importantly, though:
JOHN EGBERT IS GOING TO RETCON PUNCH SOMEONE, AND IT’S (PROBABLY) NOTVRISKA
Note the conversation. He grimaces as he’s reading the letter. Rose informs her that he must punch someone in the face. This is not a reminiscence on him punching Vriska, and asking Rose “did I do the right thing in punching Vriska”, this is John saying “Rose, do I really have to punch her in the face?”
That in mind, John is going to have to go back and punch someone in the face, and it’s going to be a girl, which narrows down the options significantly. I’m of the opinion that it’s either going to be Grimbark Jade, Crockertier Jane, or Aranea, and I’m pretty split between them equally.
I’ve made a strawpoll because I’m curious as to what you all think. Please vote on it, at your leisure.
I am Silver Tongue, I am an artist. I have many characters and you can check out my art in the art tag. I occasionally practice witchcraft though I don't do anything too complicated. I am girl 2 and don't know what else to put here.
