One day you were doing a Genocide route and you were walking down the Judgement Hall and you and Sans was far away from each other and you two looking at each other

Sans: "Welp this is... sorta nostalgic"

Sans said with his eyes closed both his hands in his jackets pocket

Sans: "But..." "We both know you just want to get to the point..."

Sans then closes his eyes again

Sans: "So... It's a beautiful day outside birds are singing flowers are blooming and says like this kids like y-"

All of the sudden in a white flash of light there's... another Sans? This one from the Pacifist Timeline

Pacifist Sans: "What the- where am I and why do you look like me"

Said Pacifist Sans in a confused tone looking around

Genocide Sans: "I could ask you the same"

Pacifist Sans looks towards you he then looks back at the main Sans and says

Pacifist Sans: "what's with the kid ?"

Genocide: "The kid... killed them all..."

Pacifist Sans: "Oh...I guess it was too good to be true...but kid why would you do this ?"

It looks like the two Sans's are about to team up to kill you what do you do now ?
