Reborn as a baby Xtale Gaster

5

(Papyrus and Undyne know. Everyone is planning on moving to a larger house/mansion so Gaster can play outside without fear.  They play around 1. to keep suspicions off and 2. They have experienced a mental regression of sorts as their soul settled.)
Gaster POV (five years old)
I smiled as I ran through the house. Sans and I were currently being chased by Undyne and Papyrus. I laughed before I ran straight into a wall. I blinked as I took a step back before I ran to the left though the door.  I looked around as I entered the garage area where Alphys did most of her experiments.  It would be easy to hide!  I smiled when I saw the large machine was still in front of the desk.  I ran over and slid underneath.  It was a larger desk but the weird machine was huge so the entrance was a perfect fit for my five year old skeletal body.  I smiled as I flared my eyelights careful not to touch any of the cables that I could now see.  I accidentally shocked myself once and it hurt pretty badly.  I shuttered as I remembered it's purpose.  I worked my way into the corner and smiled as I heard Undyne enter the room.  "Alphys!  Where does the little twerp hide?!?"  I snickered before Alphys replied in her normal blank voice.  "He hides behind the old soul separator."  "Thanks!"  I smiled as Undyne ran over and managed to scoop me up.  I laughed as Undyne tossed me around before she set me down.

I looked around before I spoke "I'm a bit tired.  Can Papa tuck me in?"  Undyne nodded as we walked into my room.  I snuggled into my bed as Papyrus walked in closing the door behind him.  He looked at me before he spoke "So why did you call this meeting?" I looked around my packed up room before I spoke. "I just wish to confirm the details about the move. So far all I know is we're moving to a more remote house and that Muffet and Frisk are staying."  Papyrus nodded before he opened his mouth but Undyne interrupted "Chara is going to stay here too with Frisk and Muffet. Also the mansion is going to be huge punk!"  I nodded before snuggling into my bed.  The pair walked out and I slowly fell asleep.  If there's two things I've noticed about the body is that I need a lot of sleep and can't stay asleep.  Luckily though I've been needing less sleep but staying asleep is worse, also I've been craving chocolate milk for some reason.  Probably Gaster's soul.  Though everyone has gotten completely used to me being awake in the middle of the night.  Sans even mentioned that it was an old habit of Gaster's, though it was also one of mine.  So if it's a double habit where we both had it than I will definitely have it, some personality traits where definitely lost or weakened as I was never a perfectionist or organized, now I'm sorta organized and vaguely presentable.

Time skip of two hours

I yawned as I woke up.  I quickly sat up and realized that I must have slept longer than an hour, that's good!  I hopped out of bed... or well tried to.  I was completely trapped in my sheets.  There was a loudish thump as I fell on the ground hitting my head.  Owwwww.  I groaned as I began to fight my sheets.  I huffed as I finally managed to sit up after five or so minutes though a part of me was annoyed and claimed it closer to 30 seconds.  I got up as I slowly walked to the kitchen to see anything.  I grabbed the remote planning to watch some documentaries or continue that Docuseries about the history of radiation.  I walked into the kitchen and grabbed the choco puffs.  I quickly grabbed some water and a chocolate milk.  I looked down at the chocolate milk before I put it back in the fridge.  Not needed.  I am very much lactose intolerant... I have no clue how that works as a skeleton.  I walked back to the counter and grabbed a bowl.  I quickly poured the choco puffs into the bowl and walked back into the kitchen where Mr. Asgore was sitting sleeping on a couch.  I saw the time on the clock 11:28.  I shrugged it off and climbed onto the couch and sat down.  I turned on the TV and lowered the volume so not to wake everyone up.  I quickly opened up the streaming service and clicked on Papyrus's profile and opened the docuseries.  I curled up and began the 3ird episode.

"So what are we watching little one?"  I shot up nearly hurling my cereal at Asgore's head.  I blinked before I replied to his question "The beginnings of the misconduct of the United States radiation corporation and the radium dial company in concealing the dangers of radiation from the girls and the death of Mollie Maggia the first sign something was wrong."  Asgore blinked before he spoke.  "Well those are some very big words.  Tell me Gaster, do you see anything wrong with those actions the...". Asgore looked down trying to remember the names of the companies.  "United states radium dial corporation." Asgore continued.  I looked at Asgore before I answered.  "Mr. Asgore, I'd be concerned if I didn't see anything wrong with it.  Because that misconduct and constant lying upon the effects of radiation upon the human body ended up causing the largest legal case of workers rights in American history."  I gave Asgore a look before I turned back to my documentary.  Asgore chuckled before he watched.  A few minutes passed as Several images of the radium girls flashed on the screen.  Happy.  Partying.  Working.  Several of the pictures showed them working on painting the dials.  I watched as the narrator continued the story with the camera zooming in on a picture of a girl twirling the bushels of her paintbrush in her mouth.  Than several images of the effects of those actions flashed past. I watched the 3D recreations of the radiation replacing the calcium in the bones and than zoomed out showing an ulcer.  I blinked as Asgore got up and walked out of the room looking a little sick.

"Oh Joy he's gone."
