So like what happens to the alpha kids after caliborns masterpiece? Do we know? And what about everyone left on earth? Is kanaya just supposed to wither away while her wife is trapped in the juju? These things keep me up at night....

We don’t know what happens to the Alpha kids after they beat Caliborn, it seems like they’re stuck on Earth but you never know. Dave could have given one of them his turn tables so they could travel in time.
