I have no idea, youre the storyteller. Start from after your universe’s Sburb I guess.
Fair enough.

Let’s see what I can remember; it’s been more than four years now.
From what I’ve gathered, our session proceeded normally until the cascade following the Scratch, as the Green Sun’s creation was not executed properly and resulted in a blindingly bright Sun that, as a result of its creation, blinded both you and me, though your sunglasses protected them enough that his vision was not entirely annihilated.
Thus bestowed with the powers of God Tier, however, I was able to determine that no successful possibilities remained for our universe, so our focus shifted to trying to break the game and attempting to force it to return backwards in time to our homes. We did so successfully, but the injuries we sustained could not be healed, so our escape did not come without its price.
Upon our return to the universe, we realized the permanence of our condition. Mother whisked me away to physicians, and, when they proved no help, to orientation and mobility specialists and Braille tutors. When I could finally communicate with you, your brother and my mother discussed matters, and it was agreed that, for your high school years, you would move to New York, under the auspices of Mother’s lucre. This allowed us to attend school together, which we did for four years.
And now I’m here in Wellesley, attending college. You’re closer to home, at the University of Texas, but we do keep in close contact.
