No one's POV:
Chara ran outside the house with a picture of the Empire State Building in her hand. Frisk ran after her.
"Come on you guys!" Asriel cried as he was trying to get the poster away from them, "This is not funny!"
"Have a little sense of humor Azzy." Chara replied rolling her eyes as she hands the picture to Frisk.
"Aw come on Asriel," Frisk said with a smile, "We're just having fun."
Suddenly, out of nowhere, you snatched the paper out of Frisk's hands with a quick swipe and slightly tripped Frisk while at it accidentally. "I told you three to stay away from my room and my stuff!" You huffed looking really mad at them, "who did it this time?!"
Frisk and Chara pointed at Asriel.
Before he could protest, you whacked him on the head with your knuckle causing him to land on the grass groaning in pain.
"OWIE!" He cried, "I didn't do it this time I swear!"
Sans happened to pass by and decided to lighten the mood.
"Geez, you kids sure know how to sneak into your sister's room and grab things without her permission."He said patting Asriel's head, "Be careful next time."
"Tch,"Chara mumbled with her arms crossed, "You're one to talk..."
Sans' eye glowed blue and Chara gave her creepy usual face when it comes to 'get ready to fight me' mode. Yes, Chara and Sans hadn't gotten along over these past few years.
Toriel comes out and is happy to see Sans but her expression changes into a scowl seeing what was going on. She wore her teacher uniform cause she was just about to head to a teacher's meeting in Ebott High School, when she came across the ruckus going on outside.
"Everyone, except you Sans, in the house now." She demanded. Not wanting to disobey her, Frisk, Asriel, (Y/n), and Chara went inside the house and sat on the couch.
Toriel soon came inside with Sans behind her closing the door.
"Ha, I thought you said 'except you Sans'?" Chara said with a mocking look.
"I said I don't mind coming in it all of you at all to her." Sans said with his usual plastered fake smile on his face, which made Chara want turn him into dust. But remembering what he was capable of doing, she just turned away and looked at the TV growling slightly. (Y/n) looked up at Toriel and back down to the ground.
"So uh..." You began, "why did you call all four of us in?"
"I called you four in because you four need to start acting more like adults..."Toriel said calmly, "just look at yourselves, you four are old enough to know how to act mature." They all looked at each other and blinked.
