Sans is grownup Lancer, you absolute non-reader!

I told you why Sans cares in that very same post. His original name is lancer. And he’s from the original Deltarune that ended in tragedy and is absolutely demoralized from that entire experience.

SANs is a Jack card with capital As written over the Js. Making him an Ace of Spades, hence why he confuses everything with the values of 1s while being the strongest enemy you can face in Undertale with the completely baffling definition of “The easiest enemy”.

Lancer is screwing with you by bending the rules of everything. That Darkner is somehow made real. Like the Knight is.
