Chapter 1

Disclaimer: I don't own Undertale just the story, AU and OCs. Thanx ;p

"So you're saying it's my fault?!"

"yeah it is, how else would you have known where it was?"

"Oh I don't know, maybe because it's the most obvious spot ever and besides I already told you I didn't take it!"

Frisk waved trying to get their attention.

"oh yeah? Then who else could it have been!"

BANG. A loud noise sounded from the kitchen, both Sans and Chara's heads turned towards it.

[Stop it you two] Frisk signed at them dropping the frying pans they had smashed together. [This fighting is getting out of hand, don't make me get Toriel in here] They sighed, [What was it even about this time]

"He accused me of taking his phone." Chara huffed in annoyance.

"she obviously took it, she's had it out for me since the underground." His left eye starting to flash blue and yellow.

"Excuse me? Who had it out for who now?" You hate me just as much as I hate you so don't even try playing innocent! Why would I even take your stupid phone, you probably just hid it to make me look bad." Her hand reaching for her pocket knife.

BANG

Another crash, Frisk had picked up the frying pans. [Stop it already! This is ridiculous, Sans I'm sure you just left it somewhere. Why is it so important anyway?]

Sans looked down a blush covering his cheeks. "i… well it's…" "His crush wanted to arrange to meet to work on their homework assignment" Chara interrupted her voice growing steadily more impatient, Sans glared at her.

Just as Frisk was going to reply there was a ringing noise from inside the lounge.

"See, I told you I didn't take the stupid thing." Chara growled at him before swiftly reaching over the coffee table to answer the phone.

"Hello?... Oh Hi Rita"

She smirked at Sans who quickly tried to grab the phone back only to be stopped by running into the coffee table.

"Yeah sorry Sans isn't here right now… Why do I have his phone, oh he left it on the coffee table you know how lazy he can be."

Sans' left eye started to flash and Chara's soul turned blue, he threw her against the wall in a desperate attempt to grab his phone. She struggled against the force only for Sans to take back the phone with a sly grin.

"hey Rita… yeah sorry 'bout that didn't have my tele-bone on me… yup Tuesday sound great, see ya then."

He turned to Chara only to throw her against the opposing wall, his eye flashing brightly. The sound of a door opening stopped him.

"What on earth is going on in here!" Toriel entered and furiously put her hands on her hips "I leave to for five minutes and the two of you have destroyed my living room, Chara to your room this instant."

"But I…"

"But nothing, go."

Chara's shoulders sank as she trudged upstairs to her room.

"This isn't over you smiley trash bag!" She yelled in annoyance from the top of the stairs only to abruptly slam the door behind her.

This was so unfair that stupid ex-skeleton got away with it and she was punished for something she didn't even start?

Ugh.

A frustrated sigh escaped her lips. This was ridiculous it's been four years and he still hadn't forgiven her four years where she had done absolutely nothing to even suggest that she was the same murderer from all those years ago.

Everyone had eventually forgiven her, even Undyne, but not Sans. And it's not like she had many friends either.

She wasn't very well liked at school because of her unusual red eyes, her only friends being her brothers Asriel and Flowey and Frisk of course who had become her best friend even after moving back with their human family.

It's not like she wasn't pretty, she had fair skin with rosy cheeks, long honey coloured hair and a slim but curvy body. The only thing that drove people away was her eyes, just like before she fell into the underground.

She shuddered at the thought.

Memories rushing over her like a tidal wave she reached out to her pocket knife and lifted the sleeves of her long shirt to reveal past scars, they were starting to fade.

A single tear rolled down her cheek as she brought down the knife again.

"Sans what happened?" Toriel asked, her foot tapping impatiently

Sans sighed, "just the same as usual, nothing too major, don't worry 'bout it Tori"

She glared at him before sighing deeply, "Fine I trust you Sans, just don't let it happen again." She turned and walked off.

Frisk turned to him, [Will you ever forgive her, you know how much she regrets it]

A deep chuckle came from Sans as he smiled back at them sadly, "i don't know if it's possible kiddo."

[Please, I'm sure if you tried you could see what the rest of us see, that she's not the same person from four years ago, please, for me?] Frisk pleaded giving him the puppy dog eyes.

Sans tried to look away but gave up resisting, he turned to them and sighed. "fine, but only for you kiddo"

They pump their fist in triumph and run over to give Sans a hug. A car pulled up in the driveway.

"Frisk, it's getting late let's go." Frisk's mother shouted from the car.

Waving goodbye to Sans Frisk walked out the door to their mother who greeted them with a hug.

"Oh hello Sans." Frisk's mother greeted, "Would you like a ride home?"

Sans shrugged, "nah it's cool I've got a shortcut.' And just like that he disappeared.

"I will never understand how he does that." Frisk just shrugged.

Well this got very heavy very quickly, there was an angst warning for a reason.
