The Sans AUs are gathered in a Group Chat (GC). Usually, it's filled with puns, ketchup talk, or lighthearted bickering. But today, the screen shows the origins of the Nightmare AUs . The chat goes silent as they realize that these aren't just "villains"—they are versions of themselves that broke under the weight of a multiverse that refused to give them a chance.

Watching the uncorrupted Nightmare—once a kind guardian—consume the negative apples out of pure desperation and fear changes the vibe of the room. The "Classic" Sans variants see a mirror of their own potential for despair. They see a version of themselves that didn't just lose a timeline, but lost the ability to feel anything but hate.
