okay, the karkat didnt know is pretty good proof. i think sometimes when off-screen stuff happens tho youre not always given all of the information in the most logical way; like for instance the chain in which the trolls entered the medium is often debated because of conflicting evidence. your comment about the kids mirroring the trolls doesnt really make sense though considering that the beta and alpha trolls were a switched-glitch group like doc scratch said. anyhow my final proof is (cont.)

that aranea on page 6669 said she was terezis ancestor in a way. but its kinda confusing so idk

When Aranea said that she meant in terms of that she predates them as her next lines are 

“[Vriska] had an ancestor whom she was aware of, and technically that is who I am.  That is to say, she is who I would have 8ecome on your world, had I arrived in her place. Alas, I did not. She was a figure in your history who preceded you 8y thousands of solar sweeps. Whereas I preceded your entire civilization 8y 8illions. ”
