Something changes. (Undertale, Swaptale.)

sans is here,
But so is everyone else.
They watch.
This is not their frisk, is it?
Sans speaks.

"Where'd you get all that LV, kiddo?" He's smiling.
His eyes
Are not.
They are shadows.
He seems... Confused.
Their look is mortified.
"How... Are you... All... ALIVE?"
"Interesting question!" "I think you could do a little bit better even if you don't think so."
"...Hey. You good?" "This world will live on!"
"F-frisk? Y-you okay there? Ar-are you having an exstestintial crisis? D-don't wort it happens to me t-too." "Undyne's dead.. We have to evacuate!"
"My child... You look... Frail... Are you alright?" "Do you really hate me that much?"
"... Hey kiddo..." "Do you want to have a B A D T I M E ?"
"N-no... W-why are you all- I- what!"
"... You wouldn't happen to... Be the monster... I've seen... In all those nightmares, now would you?" His voice almost sounded like a joke.
"M-my name's... Not Frisk. It's... C H A R A."

"Frisk. Hang in there kiddo."
*There's blood pooring from your wounds.
*The pain is intense.
"Oh.. God... Sorry."
*You can't reply.
*You receive a hot cat.

"Hey... Kiddo... You take another step forward and-"
"Sans. Don't hurt them."
He doesn't listen.
Chara takes a step.
They light up blue.
They propel into a skewer of bones.
Their health drops.
HP: 1/92
"S A N S T hat I s e nough!"
Toriel has been yelling.
*Chara clutches the real knife behind them.
"Mom!"
They cry.
"I'm here."
They felt their sins crawling on their back.
Papyrus is holding Sans, who is struggling.
"Sans! Please, cooperate!"
Sans wriggles his left hand free.
Sans rose his hand, and Chara, into the air.
"UNHAND
MY
CHILD!"
Toriel screeches, and in a split moment, a fireball lands against Sans' ribcage.
H.P: 0/1
No one moves.
Sans gasps, eyes wide with suprise for a breif moment, and then he smiles.
"Something changes."
And his dust spreads across the wind.
