Honestly, it's going to be weird the more people from the Underground show up here. With the other people here, Sans has observed a certain degree of consistency. People from the same worlds tend to be from the same timelines, occasionally with variations in the actual point they're from. The Underground has none of that consistency. Anyone who shows up here could be from any timeline, at any point in those timelines.

Papyrus is from one of the bad ones. Sans is from one of the good ones, but he never actually got to see the other side of the barrier. This place snatched him up before they could leave.

He shakes his head at the question. "nah. we're stuck here till this place lets us go."

Same old, same old.

"it's not so bad, though."
