You walk into the Judgement hall and see Sans. He's his usual self, happy, jokester, smart, nice, but you sense that he knows something you don't. You also realize he has no jokes to tell this time and it concerns you. Sans smiles at you and walks up to you and says:

San: "Heya kid, You've been Busy, huh ? Heh-Heh . . . as always. So, I have a question for you. But this time, it's a different one. How do you think your actions changed this world ? . . . . . . Not answering ? Well, I know."
