Mafia: The ancient skeleton word for family. That's what Sans was taught as a boy, there is nothing more important than one's family. But the person who taught him that was killed by his own son. Sans and Papyrus became trapped in an endless loop of death, money, and power. Then you come along. He knows things have to change or he'll lose you and Papyrus. Don Gaster must go down. This, I think, will be an attempt at a slow burn. I'll be expanding the Backstory from the original Feralmafia Short Story.
