Somehow, Harry and Gaster had become Auntie to the human child.

How they were not sure, but likely because Toriel and Asgore knew neither would react to Chara badly.

Harry doubted Chara was the child's real name, but the one they chose.

It was also cute, how they decided they were genderless. She was pretty sure they were female, but... based on how humans reacted above they'd likely been oppressed due to there gender.

"Do we add the icing now?" Chara asked, they were helping the skeleton family make cookies.

"Not yet, to warm... go yucky," Sans said, his tiny face all serious. He'd been all aghast when he learned Chara never had cookies before, everyone needed cookies.

"Don't worry, it doesn't take long," Harry said softly, idly she ran a hand through Chara's hair. The child leaned into the touch briefly, touch starved from above still.

"Lets play in my room!" Sans cried, giggling he and Asriel ran upstairs.

"Not going to join them?" Harry asked.

"Not yet..." Chara said, there was a strange look on there face

"Did you want to talk about it, I'm not Toriel but sometimes talking helps?" Harry offered.

"Why do you have a human name... everyone else had monster names?" Chara asked "Well.. except Jerry... but he's Jerry"

No one liked Jerry, except Jerry.

"I'm a traveller, a monster enslaved by humans. I met Gaster after I escaped and grew stronger, I do have a monster name but I Harry is the name I grew up with," came his reply, Gaster and Toriel and herself had talked about it and decided it was best no one else found out the truth.

"Humans.. are the worst," Chara said an air of depression.

"Chara.. not all humans are bad, the bad ones just stick out more," Harry said pulling them into a hug, there face pressed against her shirt.

"Its not right... so any monsters will be born below, never see the sun nor real stars," Chara whispered head turning a bit, so they could look at the growing bump on Harry's body.

"We have to hope, Sans saw the sun before we we're sealed so I can only hope his sibling will see it one day. Were long lived after all," Harry grinned, gently she took Charas hand and placed it on her belly.

"They kicked!" they cried excitedly, acting like the child they were.

"That's right, and you'll be able to meet them when they're born," Harry promised.

"Then I'll be there big sibling Chara said seriously there red eyes bright with happiness.

"Nooo, my brother!" Sans cries running into the room.

"He could be my brother too!" Asriel said following, soon there was a three way argument on who would be the best big sibling.

Harry watched amused, glad to see such a scene.

Her baby was going to have so many siblings, biological and adopted.

"Cookies are cool, time to ice them," she called, the arguments dropped and all three children rushed over.

------
"Sleep tight," Gaster said as he tucked in the tree drowsing children into a pile of blankets, Sans mumbled something rather nonsense like and tried to use Asriel as a plush. None of them had wanted to sleep on beds or sleeping bags, so blankets it was.

Harry kissed her mate as he returned to the living room, they soon were cuddling on the couch.

"I hope they stay friends like that forever," Harry said softly.

"I do too, did you hear the silly nickname Sans gave Chara?" he asked grinning.

"No, go on," she asked curious.

"Cha cha"

They both laughed, kids were hilarious.
