what about the beta kids

Again, depends? If they are released as some people say, they may just meet with the Alphas out in the Furthest Ring, or even just have John zap back into the Dead Session after the battle’s done. If they’re trapped forever, well. You better hope it’s another timeline then because I ain’t taking no Dead Jades at the end of Homestuck. Kanaya needs her wife back too. Karkat needs his Human Bf too. And John uh. Needs to hang out with his friends and not be depressed. They all deserve looooove.
