Undertale : a happy ending

Chapter 9 : home coming for the lost child

All three children were talking as they walked down the mountain mainly on how to break it to their mom and dad . But as they walked through town and passed the movie theater Asriel saw a poster for the new ghost busters movie and he had an idea they all rushed home and put their plan in to action. When they got home they greeted Tori and went up to their rooms Chara had gone on ahead while going invisible when they all got up stairs Frisk called out.
" MOM THERE IS A GHOST IN MY CLOSET."
Toriel laughed and wondered who it was and if it was nabstablook hiding from Mettaton after he suggested a makeover again. When she got upstairs Asriel rushed into Frisks room before Toriel could open the closet.
" Frisk are you ok i heard you yell," Asriel said in a very stiff acting voice.
Toriel looked sternly at both of them wondering what trouble they had gotten themselves into or were about to prank her with because she knew , especially since it's not to hard to figure out , when Asriel was lying. She opened up the closet to find a small fairly red ghost she recognized it but who they it clicked , Chara.
" CHARA, my child is that really you."
Chara started to tear up as Toriel started to as well .
"Yes mom is really is me. Asriel and Frisk saved me they came back for me I'm sorry that I'm a ghost but but," she started full on weeping.
"Oh Chara that doesn't matter all that matters is that you are here with us."  
Tears ran down Toriel and Charas faces soon after everyone was crying and hugging .
Suddenly they heard the door open.
" HELLO, HELLO IS ANYONE HOME IT IS I THE GREAT PAPYRUS I HAVE RETURNED FROM MY RESTAURANT I HAVE A VERY FUNNY STORY TO TELL YOU ALL ABOUT A PARTICULARLY RUDE CUSTOMER."
"We are up here Papyrus it seems we have a new friend," Toriel stated.
Papyrus at the prospect of making a new friend got very excited and rushed up the stairs.
" WHO IS THIS POSSIBLE NEW FRIEND,"he asked in a very cheerful voice.
"Oh I've been friends with Papyrus since frisk met him," Chara said.
Payrus looked confused as did Toriel so all three children began to explain. Once they were finished Chara added.
" I was the one to get Frisk to flirt with everything in sight including you Papyrus," she laughed.
Toriel was only slightly surprised as she had expected her child had a flirtatious side when she had been a human.Papyrus on the other hand was more shocked.
"REALLY YOU WERE THE ONE WHO FLIRTED WITH ME WOWIE I DIDNT KNOW THAT. SO YOU KNOW ME BUT I DONT KNOW YOU WE MOST HANG OUT AND BECOME THE BEST OF FRIENDS."
Papyrus ran off dragging Chara behind him. If your wondering how this works Chara is much closer to corporeal than other ghosts and is able to touch non specially ghost made items. If she uses enough determination she can even sit and sleep though she needs to be in the same room as Frisk to be able to uses her friends extra determination. So they will be put in the same class together which works out well.
