Chapter 2

Nightmare's Castle

Killer had just come back from stea- *ehem* buying some things for the [y/n]. This included baby formula, baby food, a high-chair, a proper crib, some toys, pacifiers, clothes, shampoos and body wash and of course, diapers.
(I'm british and i was so close to using the british words but i knew some people wouldn't understand them T-T')

Killer took all of this stuff into his room to put it away and check up on the baby. She was still asleep, just as it was when he left.

Taking a look at their appearance, he noticed how dirty it was. Dirt and mud were smudged on it's cheek, and a tiny scratch sat upon it's eyebrow, the blood dry.

Killer sighed, knowing he had to wash them. He gently woke her up, and took her out of the bone crib, making the bones disappear. He took her into his arms to take her downstairs to prepare some breakfast with the newly bought items.

He slid them into the high-chair and got to work preparing some food. He had made a bottle of milk, and had some Carrot and sweet potato baby food. He also decided to add some banana on the side because it seemed to make it happy.

Placing the food onto the tray in front of her, he prepared some food for himself, by grabbing some ketchup from the fridge, deciding to actually eat later.

Cross came into the kitchen, where Killer and [y/n] currently were. He smiled at Killer and went straight to [y/n]. Killer watched as [y/n]'s face lit up with joy at seeing cross as she giggled and made grabby hands at him. Cross smiled at this and picked her up into a hug.

"Hey little devil." He said with a chuckle. [y/n] started to fiddle with the locket around his neck, fascinated by it.

Cross just allowed them to play with the locket as he turned to talk to Killer.

"Decided whether to fully introduce it to Dust and Horror yet?" Cross asked. Killer looked at him, thinking. "Well, maybe Dust could be trusted. But I'm a bit hesitant with Horror, y'know because she's a human."

Cross nodded in understanding. "Maybe we could just introduce them when they come through." he said. Killer thought for a second then said, "Yea, sounds like a good idea."

Killer didn't want to leave it too long, incase it developed a fear in [y/n].

Just then, Nightmare came through.

"Sup boss." Killer said casually. Nightmare ignored him and moved directly towards Cross, who now had [y/n] on his shoulders.

"What's it's name?" he asked casually. "[y/n]," Cross answered. "She's pretty sweet, huh?" he continued. Nightmare let out a smile as he stretched his finger out towards the child, who reached out to grab it with a giggle.

Nightmare took his finger away and turned to Killer. "I assume you got the stuff." he said. "Yup," Killer said. "She's got everything she needs for a whole month."

"Good." Nightmare said. Killer turned to cross, who was now tickling [y/n]. He smiled before saying, "Yo Cross, we gotta bath the kid, could you help?"

Cross answered with a 'sure' and they made their way to the bathroom.

As they expected, bath time was a challenge. They ended up soaking wet from the child splashing water everywhere. It was worth it though, for she was now clean.

Dressed nicely in a clean baby grow, which was yellow with a duck on the chest. Cross took the child into his arms and took you into Killer's room, Killer following closely behind.

They decided to patch up the child's scars and tend to the bruises.

Once completely patched up, Cross decided it was time to introduce them to Dust. Killer was a little hesitant but agreed anyway.

Making their way to Dust's room, [y/n] sat comfortably on Cross' shoulders, it seemed to enjoy riding his shoulders.

Dust opened the door, hearing a knock. He looked at the two confused, then saw the child on Cross' shoulders.

He smiled, but it wasn't gentle, more maniacal. Killer sighed at this, telling Dust why they're here.

Dust let them in, sitting on his bed while Cross and Killer stay stood a little further away.

Cross and Killer introduced Dust to the child, and explained why they've kept them. Dust looked at the child, thinking. He then stood up and slowly walked towards it.

When he reached them, he smiled, but this time it was gentle. He chuckled as the child made grabby hands to him.

"Am I allowed to hold it?" He asked, knowing Killer didn't fully trust him. Killer thought, he looked like he was having a battle with himself.

Eventually, Killer said, "Yea, sure, but for now I'd rather you held her when either me or Cross are with you. Just for safety." with an apologetic smile.

Dust smiled, reassuring him that he's ok with that. Cross handed [y/n] to him.

[Y/n] giggled and Dust started to introduce himself to them. "Hey little devil, I'm uncle Dusty," he said with a gentle smile.

Killer slightly yelled, "Why does everyone keep appointing themselves uncle?!"

Cross and Dust chuckled at this.

Dust continued to talk to the child, "I'm telling you now, I'm gonna be the better uncle. I'm just cooler." He said with a smirk.

To this Cross started yelling, "No way! She already likes me more than you." He said crossing his arms like a child.

They decided to spend some time with Dust, letting [y/n] get used to Dust's company.

Dust was currently trying to get [y/n] to talk, "C'mon, say 'Dusty', I know you can do it." To which Cross responded with, "No no, say 'Cross'."

[Y/n], who was sat on Killer's lap, looked between them and giggled. She then decided to try and talk, blurting out "Kewa." (Killer).

Killer looked down at them in awe, then smirked at Cross and Dust, who just looked upset.

Killer looked at the time, seeing that it was getting closer to the time she's supposed to nap, and the next meeting.

"I'm gonna go settle them down for their nap early so that she'll be asleep by the time the meeting starts." He told them, getting up.

Cross and Dust waved goodbye as Killer walked to his room. He would've teleported, but he doesn't know how that would affect the baby, so he continued to walk.

Once he made it to his room he changed her into a pink and grey striped onesie, it had a picture of a white bunny in the middle.

He set it down in the crib, and went to the shelf to pick out one of the books he had gotten for her.

He decided on 'Where the wild things are'. It looked like a decent book. (childhood book, its so good).

He sat and read to them as they slowly drifted off to sleep, peacefully entering dreamland.

Killer smiled, coming to the end of the book. He set it down and looked at the sleeping child. He 'kissed' her and set up the baby monitor, tucking his end in hid pocket.

He then teleported to the room where the meeting would be held, seeing Nightmare, Dust and Cross already waiting.

"Where's Horror?" Killer asked. "He'll be here soon." Nightmare responded. Killer nodded and sat down at his designated place.

Once Horror had arrived and sat down, Nightmare started the meeting.

"I've brought you here to talk about the child."
