UNDERTALE ONE SHOTS!

Mixed up in he timelines

     You were walking down judgement hall holding an object but you didn't know what it was.

"*Heheh so you reveal yourself now huh?*" you look up to see a sad and mad Sans
"S-sans what's wrong?" You asked
"*WHATS WRONG?! ARE YOU SERIOUSLY PULLING THAT JOKE RIGHT NOW?!*"
He seemed angered you didn't know what happened until feel someone's hand on your shoulder.
"Look at the knife!" The voice said.
You look down to see a knife
'What?!' You thought to your self.
You then realized the person was
CHARA.
You turned around seeing her cackling
"Just kill him!" She laughed out
You turned to see Sans left eye glowing light blue.
You know he means it.
So you have something up your sleeve to.
You drop the knife and drop to your knees opening your arms out.
"A hug? THATS THE BEST YOU CAN DO KID?!" Sans shrieked
Your shook your head no
"Give it your all" that's all you say
Sans then attacked you and you don't dodge you take the bullets. Even though Though it hurts, it feels like the right thing though.
Sans was confused on why you weren't dogging his attacks or even fighting.
He then saw you get up and grab the knife.
"Sans I just realized, I'm in the wrong timeline."
You smile while sans was so realizing that's why. You then pointed the knife at your heart ready to puncture it
"K-kid? What are you doing?" Sans realized since you weren't bad your his only family or friend alive.
" I have to get the timelines normal again, sorry but I have to."
Sans was about to shake his head but you continued.
"Because if I'm hear then think we're is the bad one?"
Sans eyes widen and then sadly nodded
You puncutred your heart
And smiled as Sans was crying
"It's ok." Was all you said before appearing back to the spot you were in.
