Sebastian often heard Vincent use the term 'blink and you'll miss it', which was likely more real to a man with only one functioning eye.
Yet, as Sebastian watched Ciel grow, he found it to be true; he had hardly met the boy before he was watching him bloom like an icy lily.
His big, blue eyes lost their fuzziness and gained clarity, his upper lid lowering into something that resembled a cat, if one stared too long, though Ciel didn't often maintain eye contact long enough for it to go noticed. His jaw began to sharpen, slower than his eyes changed, and though he didn't get much taller, by the time he was thirteen, he was lean and moved smoothly. He moved, sometimes, too smoothly for a regular human, and people noticed.
He began to disappear from the manor for large amounts of time, though only Sebastian noticed.
Sebastian also noticed that family began to visit the manor less and less. Once it was rebuilt, Ciel's two aunts and cousin came in and out of the place like it was their own, doting upon Ciel and tiptoeing around Vincent, but slowly tapered off.
Everyone noticed the brutal murders that began to crisscross London.
Somehow, only Ciel noticed how strange his aunt's new servant was.
Vincent only noticed that his sister-in-law was acting different when she disappeared with his son.
"Aunt Ann-"
"-Shut up, shut up, SHUT UP! You don't deserve to be alive!"
And Ciel was silent, alone with the woman who loved his father too young and the man that wasn't really a man.
Another woman was dead on the floor. Ciel had never known her name.
Ciel huffed in a breath, which wasn't easy. His aunt's hands were pinning him to the wall by his throat, too tight to let him breathe but not tight enough to strangle him.
She sobbed again, hands still bloody.
"Don't look at me like that." She demanded. "You look too much like them both."
"This won't bring your baby back." Ciel told her calmly, sorrowfully. "I could tear the world apart, Aunt Ann. It'll never bring my mother back."
Angelina screamed, and drove the razor blade she had just used to slice a woman apart into her nephew's side.
"Sebastian, stop her!" Vincent ordered, giving away his hiding spot, far since too late in intervening.
Sebastian didn't even have the time to move before a gunshot rang through the room and the woman in red stumbled backwards.
Ciel hit the ground with a grunt, but lifted the pistol again and fired cleanly. He never even flinched.
Angelina hit the ground without uttering another word.
"A little late, father." Ciel grunted, letting the gun fall to the ground and closing his hands around the blade still embedded between his ribs.
The reaper in the room locked his eyes onto Sebastian.
"Oh, how I would love to take that little bitch with me, too, Bassy! But you'd never let that happen, would you? Mhmm, how I would love to have you chase me down~"
Sebastian didn't even look in his direction. He didn't care.
Ciel, still in shock, smiled as Sebastian knelt near him, his father quick to follow.
"Sebastian, get him to the hospital. I'll catch up; just get him there."
Vincent ordered, and Ciel laughed weakly, breaking into a cough.
Blood spilled onto his lips.
"Father, really, Angelina needs to get to one too. The least we can do is make sure a doctor announces her death."
Ciel tried to laugh again, but passed out as Sebastian lifted him.
"Go, Sebastian!" Vincent demanded, and he did.
Sebastian didn't see the scar the blade left until Ciel was almost fifteen. He saw the scar that killing his aunt left the second Ciel's eyes opened again.
