Disclaimer: I don't own HxH expect Kaullo

A certain brown haired toddler climbed out of his crib. He succeeded into leaving his room without Milluki-who was supposed to babysit him-noticing him. He crawled to a door and crawled inside.

No toys, no blue, no smell of the chocolate his brother loves so much. Nope ,this is defiantly not Killua's room. Curiosity got the best of him when he saw a red button on the nighttable. He knew that red buttons mostly meant trouble(He has been observing the action movies Killua watches),but for now he didn't care. He climbed on the bed and pressed on the red button…

Nothing happened. He tried it again and tilted his head to the side as the room became dark. It became black.

The light returned and there were now many pictures of Killua on the wall."Webe aw swaker iwn fis sfoemi?" He asked himself.(Transalation: We have a stalker in this family?)

His eyes turned to the door when it opened. A boy with shoulder-length black hair walked inside. His emotionless eyes met his green orbs. The words escaped his mouth as his face was still emotionless, "What are you doing here?" Kaullo didn't answer and stared pointedly at him.

The boy proceeded to look at the pictures on the wall before sighing. He walked to the nighttable and pressed on the red button. The pictures on the wall disappeared. While doing all of this, he was ignoring the toddler sitting on his bed.

"Waga!" The toddler reached his hand out and pulled at the black hair….. hard.

For the first time the boy made a facial expression : One of terrible annoyance. "Can you please stop pulling at my hair ?"

"Swaker!" Kaullo glared at him…. It looked more cute then angry though.(Translation : Stalker!)

"Are you angry about the pictures?"

"Swas!" Was the toddler's reply.(Translation : Yes !)

Illumi sighed. "Look, I don't even know what you're doing in this room, but can you please leave."

Kaullo was about to open his mouth to yell but his stomach made a loud rumbling noise. "Iwa frungry!"(Translate : I'm hungry!)

"I can hear that," Illumi deadpanned.

Kaullo puffed his cheeks as Illumi carried him In his arms and walked out of the rooms. "Oh believe me, I don't like this either. But I, and the other brothers too by the way, have to take care of you if our parents are not there." Illumi said.

Kaullo blinked, jostling slightly as Illumi moved him to rest more comfortably on his hip while his other hand pushed the door of the kitchen open. Illumi put Kaullo on the kitchen table before opening the fridge. "What do you want to eat?"

Kaullo just stared at him.

"I repeat, what do you want to eat?"

Kaullo felt small laughter bubbling as he felt that his older brother was starting to get annoyed. He he held his hand up. "Bwome wfi!"(Translation : Come here.)

It seemed that Illumi understood what he said, because he walked over to him. Kaullo took a hold of Illumi's cheek and pinched it."Bjou wawa nwot swo bwad!" (Translation: You are not so bad.)

"…"

"Bwoob bwawewe bjou lwike! Kwaullo bwill swufely lwike bwit !" (Translation :Cook whatever you like ! Kaullo will surely like it)He grinned at him.

Illumi took a stool and stood on it while he rummaged through cupboards. "Since I have no idea how to make baby milk, I'm just going to make you pancakes." Even though that Illumi was an assassin, he wasn't trained how to make baby milk. He found the needed ingredients. His head turned towards the door as he heard it open.

"Aniki! I also want so pancakes!" The future heir puffed his cheeks. "You make pancakes for Kaullo,but not for me? How unfair!"

Illumi sighed. "Fine, fine. I will make pancakes for you too."

"Kiwu!" Kaullo yelled out happily. (Translation: Killua!)

Killua grinned at the toddler. "Hi, Kaullo! Happy to see you too." He grabbed Kaullo and swung him around. The toddler screamed in glee.

Illumi decided to ignore the two and continue making the pancakes. He threw all the ingredients into a bowl and started stirring. Killua wanted a lot of pancakes, so he told Illumi to make more. Illumi was a bit surprised, but went on with it.

During his mother pregnancies, he had done this a lot. Maha didn't even know what cooking was, Zeno refused to cook and Silva wasn't even allowed to be near the kitchen(That was because he once almost burned down the kitchen when he was trying to make a omelet).

"Kiwu, fwiwer! fwiwer!" Kaullo screamed as Killua was throwing him in the air and then catching him again with ease.(Translation: Killua, higher! Higher!)

An invisible vein appeared on Illumi's forehead. It was almost impossible to concentrate with two screaming children close to him. Some minutes later, he was flipping the pancakes through the air onto a plate, causing Killua and Kaullo to stop their game to look at him with amazement and fascination.

He finished, presenting the food to his two younger brothers. Killua immediately started to eat while that Kaullo was staring at Illumi as if he was a nut.

"Don't tell me you haven't seen a pancake before?" He held one up in front of the toddler's face. Kaullo blinked. "Oh come on. Mom ate a lot of them during her pregnancy." Kaullo gaped at him. Illumi rubbed his forehead and sighed. "You're hopeless." Kaullo puffed his cheeks.

"Look Kaullo…" Killua picked up one of his plate. "Bite it like this." He took a big bite of his pancake. "You see?" He said through mouthful.

Kaullo nodded and grabbed a pancake, taking a really, really small bite.

"If you continue like that, it will take years before you finish it," Illumi deadpanned.

"Leave him." Killua scolded him. "You have to act nice to Kaullo! If you don't, I won't talk to you anymore!"

"….Fine. I'm sorry."

After two hours Kaullo was finally done with eating his pancakes. Since it took so long, Killua fell asleep. Illumi sighed as he had to carried the two to his room. Kaullo and Killua snuggled up his chest. He would have preferred to sleep alone, but he supposed that one time wouldn't hurt.

The next morning the Zoldyck's were eating breakfast at the table. Kikyou placed Kaullo on her lap and tried to feed him is oatmeal. "Come on, Ullo…" She said. "Eat this. Do it for mommy, for me."

Kaullo shook his head as fast as he could and looked away. "Hmp."

Kikyou sighed and looked at her husband who was busy talking with Zeno. "Silva, Kaullo is starting to get anorexia."

Silva looked at her and then at Kaullo. "He probably doesn't want to eat his meal."

Kikyo sighed and turned back to Kaullo. "What do you want to eat, Ullo?"

Kaullo smiled at her. "Pa-Pa…"

"OH MY GOSH!" Kikyou screamed, almost blasting off everyone's eardrums. "SILVA COME OVER HERE! HE'S GOING TO SAY PAPA!"

Silva walked over and stared at his son. Everybody was silent, waiting for Kaullo to say that special word.

"Pft-I can't even…" Killua tried his best not to laugh. He knew all too well what Kaullo was going to say.

"Come on, Ullo, say it!" Kikyo encouraged the youngest son.

"Pa-Pancake!"

Killua fell off his chair and started laughing.

The rest of the family stayed silent, just staring at Kaullo.

"W-What?"

"Pancake!" Kaullo looked really confident and he pointed at Illumi. "Pancake!" He reached out for Illumi, who was suddenly really interested in his poisoned food, behind him Killua was sitting against the wall, still laughing.

Kikyou sweat-dropped. "I don't understand."

"He wants pancakes, I don't see a problem." Silva shrugged and went back to talking with Zeno.
