He jokes, but...it came a little slower than his last couple jokes. His eyelights fixated on the map, she feels like he might enjoy this a lot more than he lets on. Or maybe he doesn't enjoy it at all, but this reaction is a little bit different, and it gives Luna a small, warm feeling.

"Do you like them?" Maybe the stars are really bright where Sans is from. Maybe he has a chart of his own. Maybe he's from space. Wouldn't that be amazing? Regardless, he's here now. She stands next to him and holds out the map as far as she can in front of both of them, pointing to a nameless, shapeless cluster of faded stars. Not enough to be a constellation.

"There's...not a whole lot right now," Luna admits, not trying to sound disappointed, but it can't help but leak out of her voice. She looks to him. "We might have to wait a while for something to show up-- but when it does! We'll be ready!"
