There was dust, there was murder, it was everywhere. And it's because of you. You are the reason the monsterkind is going extinct. What is wrong with you? What have you done? Sans had observed it from afar. The way you walked away mercilessly after killing someone. The way he saw you kill his friends... the way he saw you kill his brother. And once you arrived at Judgement Hall, he had already stood there, menacingly awaiting your presence.
"so... you came. been busy, eh? i could tell. what do you think about us? freaks? i get that it might be self-defense, but isn't it too far? it doesn't matter anymore."
BATTLE, START!
"it's a terrible day outside. birds are crowing away, flowers are withering. on days like these, monsters like me..."
The light from his Gaster Blasters's beams flashes your eyes.
"WILL HAVE A GREAT TIME KILLING YOU."
