"pap here just wants to check out the surface again. he's--" Sans started.
"JUST SPARE ME THE PUNS, SANS." Papyrus cut him off.
The shorter skeleton rolled his 'eyes'. "....he's excited,"

Frisk nodded. *Papyrus, I hate to hurt your bubble, but maybe dont throw a big show or something. They might get REALLY scared. Trust me, I know that. When I first met Sans I was terrified. Until the whoopee cushion hand trick, anyway.*

Sans bit back a laugh as Papyrus gave him a strange look. "what? you should've seen their face."
Papyrus huffed. "YOU HAVE THE SENSE OF HUMOR OF A FIVE-YEAR-OLD..."
"well, your jokes don't get incidental rimshots."

*i think they were actually scared of you, Papyrus. With all due respect, we dont have any monsters like you on the surface.*

Papyrus considered this a moment. "... WHAT IF WE WERE TO STAY OUT OF SIGHT?"
Sans's expression was one of conflict. 'Stealth' was not a word you associated with a guy who spoke in full-caps. Still, the more powerful, supportive side of him said "that ain't a bad idea."

Frisk shrugged. *we may find you. we have devices that scan the whole world from space.*

Sans's eye sockets widened a bit in surprise. The good kind, mind you. "wait wait wait, hold the phone, let me get this straight, you humans made it to space?!"

*were trying to get people on Mars right now.*

Sans grumbled something under his breath. "lucky."
This exchange just went right over Papyrus's head.

Frisk grinned.
