since the issues in the beta kid's session were because of issues in the universe itself i take they probably would have manifested in every b1 session. imagine them trying to deal with that without any of the inside knowledge the trolls provided, yeesh. also, what kind of influence do you think the beta kid's Scratch would have had on the other b1 sessions, if any? do you think it would have wiped them out?

Actually, given Karkat identifies the Kids’ Rogue Jack as the manifestation of the Frog’s Cancer, it’s very likely every other Session would be completely untouched by this, which doesn’t mean Jack wouldn’t still totally be able to shank the Queen and go on a murder rampage. And while the Incipispheres are separate from the Universe, given they are still linked to Beta Earth by the copy of the game deriving from the Beta Frog Temple, it’s fair to assume the would’ve been wiped out as well. Hard Reset.
