The cellar hid a dirty little secret and all families have secrets, thus our family was no different. No matter how curious we were, we remembered Rei's scars and never thought to open the door. There were things we knew about the cellar. At night, we heard some kind of pained wails, which vaguely sounded like crying, and it came exactly from behind that door. There was also the fact that the door was dead-bolted and padlocked. There was no denying something lived down there, as the Mistress was bitten whatever our family's secret so happened to be.
Whatever our family's dirty little secret was, it feared her just as much as we did. We never knew why but even a housefly could tell it feared the Mistress enough to bite her. Whatever it was so happened to have been brave, as it bit her, leaving her with a scarred hand when she healed. Quietly, we found our frightened selves admiring it. Of course, eventually, we resolved to call "it" a "she" and she became known as only "She", as neither of us knew what to call her otherwise and, as far as we knew, "She" was female.
"Once," Nui whispered, one night, when she was eight, "I found a photo in the attic of a little girl." I was intrigued naturally and asked her what did she look like, to which Nui responded, "Oh, well, she looked really sad, had black hair with a streak, and blue eyes." At the time, I dismissed the possibility that this little girl in the photo was the cellar secret, at the same time, said photo like the ones of our father, was hidden away, leaving us to unaware of its existence, until Nui found it in the attic. The attic, like the cellar, also had secrets, however, very much unlike the cellar, the Mistress didn't care if we had gone up there and neither were we not allowed.
Like that padlocked cellar door and as time passed since Nui mentioned the little girl in the photo, I found myself instinctively drawn to her, yet nothing in my mind made a connection between her and the presence downstairs. Of course, I wanted no more to unravel both mysteries, yet, I wasn't too particularly sure as to how. Nui did bring up that Rei may know who the girl was, which would be somewhat preposterous as Rei is a very fearful soul, who'd much sooner commit suicide than reveal what she knew for fear of the Mistress' punishment. Still, she wanted no more than to ask that secretary what she knew, to which I said, "No! Leave Rei be, you'll drive her to her grave if you ask."
