Thank you for your positive reviews on my Sebastian-centered fic, I promise it is STILL ONGOING, however I found this a while ago and have been tweaking it ever since the idea popped up. It is complete and I will be doing regular updates on it, no long waiting required.

WARNING-This fic might be considered very angsty and dark for a lot of people, if you are sensitive to emotional scenes or severe cases of Stockholm Syndrome, PLEASE STAY AWAY!

Also, I'm not trying to please anyone with this, It's been sitting in my phone for a while and came up when I backed it up on my pc. I just wanted to get my twisted story out there with the others of its kind, but I promise this will not be an M rated fic in any way. Just my way of MESSING WITH YOUR FEELS. MWAHAHAHAHA.

Disclaimer-I do not own Kuroshitsuji/Black Butler in any way.

Reliving Childhood-Toddler Trouble

"Are you willing to pay the price for my services, earl Phantomhive?"
Ciel looked at the Undertaker with a bored expression and waved his hand, signaling for Sebastian to get on with it.
Honestly, what kind of reaper retires to a funeral home in the first place? And asks for laughter as payment?
Ciel ignored the story Sebastian was relating to Undertaker, instead focusing on the current case.
It was barely anything worth his time really, a murder at several funerals had occurred throughout the week, and naturally, Ciel has come to an undertaker to get answers.
The only reason he'd taken up this case was because the murderer was targeting children, and Ciel had a particular distaste for those who pick on the weak, especially children.
Ciel was brought back to reality when the Undertaker laughed and giggled in his usual insane way, and Sebastian stood at his side, a satisfied look on his face.
"Now tell us what you know, Undertaker." Ciel demanded, having met the requirements for his knowledge.
Undertaker lazily stood from his chair and pulled something from his sleeve, holding it up. Ciel stepped closer and saw it was a vial, with thick, purple liquid inside it.
"This strange concoction was found on each of the victims," He said, shaking the vial. "I 'avent tried it for myself, but I believe it resembles a potion for de-aging someone."
He handed the vial to Ciel, who stared at it intently for a moment before looking up again.
"Anything else?" He pried.
Undertaker seemed to ponder something, and the grin on his face widened as he bent down and put his face up to Ciel's.
"I've also found this substance on a few children of noble birth, ones who hadn't attended a funeral of any kind."
Ciel immediately caught on to what the Undertaker was suggesting, and looked down to the vial in his hand.
"Obviously that means I would have to drink whatever is in this vial in order to attract the culprit." Ciel said blankly.
Sebastian looked down at him in uncertainty and gently took the vial from the earl, popping off the cork and raising it to his nose. After a short moment, he pulled it away and corked it again, handing it back to Ciel.
"There's nothing particularly harmful in it." Sebastian confirmed. "At least, as far as I can sense anyway."
Ciel nodded and thanked the Undertaker curtly, pocketing the vial and leading Sebastian out of the mortician's establishment. They walked quickly to the waiting carriage and hurried back to the town manor, where Ciel and Sebastian went to Ciel's bedroom to test the vial.
"If I collapse, I want to fall on my bed at least." Ciel said dryly, yanking the vial free of its cork.
Sebastian stood as near to him as he could, wanting to catch the young master should he fall away from his designated landing spot.
Ciel hesitated for only a moment before raising the vial to his lips and drank the liquid till there was not a drop left.
At first, he felt nothing, not pain, nothing.
"How do you feel, young master?" Sebastian asked him, stepping closer.
Ciel was about to reply that he was fine, when a tingling sensation came over him, making his legs feel weak. He sat down on the bed and held his head in his hands, feeling as if someone has taken a hammer and begun striking him in the temples.
"Sir?" Ciel heard Sebastian call. "What's the matter?"
Ciel couldn't answer as the tingling turned to a burn, causing him to double over till he was almost bent in half.
Ciel suddenly felt dizzy, and the room around him seemed to get bigger as it seemingly swirled around him.
He didn't realize the pain had stopped until he felt someone tugging on his wrists, which were jammed tightly over his ears.
Gradually, he removed his hands from his head and looked up at his butler's face, which seemed much bigger than it had before.
"Se...bastian?" Ciel's eyes grew wide at the sound of his own voice, now high and baby like.
"I'm afraid you've transformed into a smaller child than you had been before, young master."
Sebastian told him, reaching over and picking him up, only his shirt staying on his shoulders.
Sebastian carried him to a mirror and showed Ciel his new form, a four year old, by Ciel's guess. This was about the age where he'd begun to remember things, and his memory was fresh with scenes of his parents, Elizabeth, and Madame Red.
"I...think I'm four." Ciel said finally, seeing that his contract with Sebastian was still in place.
"I believe you're right, young master." Sebastian said, putting him back on the bed and stepping back.
"Well now that you look the part, we need somewhere for you to play out this act."
Ciel looked puzzled as Sebastian came over and tossed the blanket over Ciel's head, making him grunt in indignation.
Ciel scrambled out from underneath the blanket and looked around, a look of shock replacing his embarrassment.
His room had been transformed into a nursery, with toys piled high and a toddlers bed replacing his lavish, king sized one.
There was a rocking chair in the corner, and a playpen, along with stuffed animals scattered on his bed. It would have been a toddlers perfect dream, had Ciel actually been a child.
"I don't see how a nursery would help anything." Ciel said, ignoring the look of amusement on Sebastian's face at Ciel's pout.
"It would give our suspect suspicion if you were to stay in a normal room at your age wouldn't it?" Sebastian answered, removing Ciel's overgrown nightshirt and replacing it with a sailor style shirt of blue and white, with blue pants to match.
Sebastian slipped socks over his feet but left out shoes, which confused Ciel.
He had no time to interrogate however, for Sebastian plucked him from the bed and walked the short distance to the playpen, depositing Ciel in it.
Ciel let out a cry of indignation and jumped up, the top of his head barely reaching the top of the bars.
"Get me out of here this instant!"
Sebastian resisted the urge to chuckle and bent down, patting the earl's head gently.
"I'll be right back, I'm simply going to explain the situation to the servants, and start on dinner, it won't take long." Sebastian told the glaring child, standing straight and hurrying out of the room before Ciel could object.
Ciel growled and grabbed the top of the bars, attempting to hoist himself up.
He failed miserably however and ended up falling onto his back, his head smacking the bottom of the playpen.
Ciel sat up and rubbed his head, fighting back tears. How dare Sebastian just leave him here like this! Once the butler returned, Ciel swore he would make him pay, dearly. With renewed resolve, he stood up once again and looked around, spotting a few thick baby books scattered around the cage he was in. Ciel grabbed them and stacked them up beside the bars and stood on top of them.
'Just a little higher!'
He reached up and pushed himself up onto the bars, yanking his feet over the bars and lowering himself gradually. He was too short to reach the ground, and he dangled there helplessly, contemplating his options. He could jump, albeit he might sustain a few scrapes from it but it would work. Ciel took a deep breath and loosened his grip on the bars. He grit his teeth and looked down.
Big mistake.
Ciel barely had time to let out a yelp as he lost his grip on the bars and was sent tumbling and crashing down to the ground.
The carpet did little to cushion his fall and he fell flat on his back, hitting his head AGAIN.
Ciel laid there for a good several moments before the pain outweighed the shock, and he started sobbing loudly.
He didn't bother trying to hold back, nor did he muffle his screams. He cried in long, broken sobs, tears streaking down his pale face.
Why had acted so foolishly? He could've ordered Sebastian to come and he would have had to, no matter what, a master's orders are absolute.
Ciel rolled over onto his stomach and clutched his head, trying his best to calm down. His emotions were no longer as easy to control as they had been, and he ended up burying his face in his arms, refusing to move from the floor.
"S-Sebas...SEBASTIAN!" Ciel screamed with renewed vigor. He waited a few moments, thinking he wouldn't come, when he heard the door open and the tell-tale footsteps of his butler's shoes coming closer.
"Oh dear, what a mess."
Ciel felt himself being lifted from the ground and he instantly squeezed his arms around Sebastian's neck, still crying.
"It's alright now, did you fall? What hurts?" Sebastian asked, running a hand through his hair.
Ciel screamed when Sebastian's hand brushed the newly recieved bump on his head, shaking the hand off his head.
Sebastian sighed and walked over to a small table in the room and sat Ciel down on it, kneeling in front of him.
"Did you hit your head, young master?" Sebastian asked, ignoring the child's arms as they reach out to be held.
Ciel finally jerked his hands back and nodded, watching as Sebastian stood up and walked over to a dresser, opening a drawer and pulling something from it.
Ciel managed to reduce his crying to hiccups, all the while keeping his gaze on Sebastian, who returned to his side and reached for his head.
Ciel smacked his hands away and yelled a somewhat dignified 'No!' and placed both his hands around the spot on his head, refusing to move them.
"Young master, if you don't move your hands how am I supposed to make sure it heals properly?" Sebastian scolded, taking Ciel's wrists in his hands. Ciel knew he was being difficult, and he let the teenager inside him allow Sebastian access to his 'wound'.
He'd been injured before and Sebastian had always made sure it didn't get infected and that the pain was kept at a bare minimum, now would be no different.
Ciel let out a few stray tears when Sebastian moved his charcoal colored hair out out the way and rubbed cream on it, blowing softly to ease the sting.
Ciel held still for the most part, rubbing the last of his tears from his eyes and letting out a soft kitten-like yawn once Sebastian finished up.
Sebastian chuckled in amusement and picked up the young earl, letting Ciel get used to being carried.
Ciel knew he should be arguing, or at least embarrassed that he was thirteen and being held like this, but he was too tired to say or do much of anything besides curl up against Sebastian and sleep.
