Flat was an unwanted child, a soul despised by his own parents. He was meant to be deleted, as needless data I wasn’t going to absorb anything from.
But guess what? Flat noticed me.
He found me in there. Can you believe that?
Ever since he was conscious, he could tell I was living under the circuits that composed him.
His genius has nothing to do with me... I think.
He had my body in its perfected state but it was through his own sharpness that he managed to manifest my abilities, even if only my eyes. And that’s not even the most amazing thing about him.
