Once apon a broken time

Following Toriel's death with Sariel a baby, Frisk being dead and Jazzmine not coming to claim the throne, Sans was crowned the new monarch.

"Hey Bro!" Papyrus sat on the ground beside the throne 

"Hi, Papyrus," Sans looked at his brother "want a fold up chair or something?"

"Nah, I'm good!" Papyrus dismissed Sans' offer

"You know while I am doing King stuff, you need to take care of Sariel" Sans informed 

"WOWIE! REALLY?" Papyrus bubbled 

"Uhh.. yeah" Sans sat up straight "you are the.. uhh.. Royal.. babysitter..?" 

"WOWIE! THIS IS THE BEST DAY EVER!" Papyrus hugged his brother tightly

"And you can practice jokes in the ballroom's microphone" Sans said as he tried to wiggle out of Papyrus' hug to no prevail.

"Cool!" Papyrus ran off to practice comedy routines in the microphone with a stuff animal audience 

Sans went to his daughters bed chamber to see if she woken up yet

"Hey Doll baby, the funeral is soon we better get you dressed" Sans gentle shook Sariel wake in a hushed tone and got her out of her crib then turned around to see Alphys 

"Good day, Mr. King, your highness, magisty, commander, boss, dude, sir!" Alphys saluted 

"Okay...?" Sans was a little off put from the atempt of formal introduction from Alphys

"I need to inform you that where do you think the dust should be put? Podium or thing that Toriel very much likes?"  Alphys continued to awkwardly salute

"First, stop saluting, second to answer that, we can do both" Sans responded Alphys nodded in return

The funeral was that her staff and crown and some of her dust in a bag was put in a display case in the hall of past royal family members, even monster kid's dust was in the hallway.

The rest of the dust..

"Hey Sariel, you know they said put it on Toriel's favorite things," Sans begain "well, you're not a thing.. but.." Sans put it on Sariel's head causing her to sneeze "you definitely Toriel's favorite thing to come into her possession" 

Alphys got jealous of her role model and father like figure not paying attention to her, even after Alphys was a member of the royal guard after Myrtle decided to retire.

Grandpa Semi still kept his position as being Royal scientist and advisor and basicaly nothing really changed..

Or so thought..

Alphys walked home and when she reached the door the world went black and red

"SANS DOESN'T HAVE TIME FOR YOU ANYMORE, HUH?" a voice came from behind, Alphys turned around

"Who are you? And where am I?" Alphys looked around her surroundings, everything was the same but just red outlined and empty, no one to be found

"I AM FRISK AND THAT'S NOT OF IMPORTANCE, I AM HERE TO TALK TO YOU" Frisk responded 

No other choice Alphys nodded and asked "About what?"

"OH, YOUR JEALOUSY OF EVERYONE WHO SANS IS PAYING ATTENTION TOO," Frisk shrugged as she continued to use her wings to hover off the ground "I MEAN, HE IS YOUR BASICALLY FATHER YOU NEVER HAD AND HE DOESN'T HAVE TIME FOR YOU"

"I guess that's true.." Alphys looked away 

"DON'T WORRY, I HAVE A PLAN AND IT'S ALL COMING TOGETHER" Frisk Dreammurr smirked and the world went back to normal in a pulse of white and red
