Sans chuckled as she choked when trying to best him. He'd had a LOT of time to practice, but still, he'd figured she might win, considering the lips vs no lips argument. He took another chug of ketchup before sitting upright in his chair and winking at her,"Heh, my secret talent, having no lips."

He looked down at his plate, ready to take another bite, at least until he noticed it was empty. With a shrug to himself, the stout skeleton helped himself to a second round.

He ate in comfortable silence with Frisk, glad the awkwardness from before was gone. He could feel the subtle swell of his bones as he, once again, over ate. But it was a comforting sensation. Like how Frisk rubbed her hands together when she was nervous, it was a reassuring pressure in his bones. Heh, with that kind of thinking, it made him sound like old bones... But he was old. Just exactly how old, he couldn't recall(he'd lost a lot of time in those resets), but he was older than Papyrus, and much older than Frisk.

Not that Sans could remember his beginning. His entire life before Paps had stepped in as just a sweet little baby bones was a blur of blackness and pure, meaningless existence. Even when Paps had asked about his life before, Sans would just dismiss it and say his life began the day Papyrus was there.

So many years had passed since then.

Sans slowly looked back up at his human companion. Frisk... She was a human. And even with his lack of experience(even after all this time), he knew that human lifespans were limited and quite short.

Frisk was already twenty. She was entering her prime years. And after that.... After another few decades, she would die of old age, if no health problems occurred.

Could... Could he really live with that?

Sans' soul twisted and he took a large bite of spaghetti, his playful slurping gone as he was lost in thought. He needed a solution. Monsters, being composed of magic, weren't really all too susceptible to the wearing of time. That's not to say they didn't age, or even die from old age, but their lifespans were much longer, their prime extending over three times what a human's was.

But how could he find the cure to death?

Alphys' research. Her synthetic determination serum, it had to be the key. He would go to her and ask about it tomorrow.... No. She was already working so hard on destroying the barrier. She wouldn't have time to invest in both, not to mention, the clock was fast ticking for Frisk.

Noticing his plate was empty once more, Sans pulled the pie closest to him closer and began to slowly eat. He needed to calm down, if he was frantic, then Frisk would be on edge and worry.

He needed a distraction until Frisk was asleep. Then he could begin... Preparations.

About a fourth of the way through his pie, he sat back in his chair and took another swig of ketchup. Smiling softly to Frisk he stood,"How 'bout we move this party to the couch? I think some tv'll cap off such a nice night."

Shuffling over to the sofa, he lazily resumed his claimed end and pulled out the remote. He uninterestedly flipped through the channels, not caring what they watched, just hoping that it would be enough to help her fall asleep, and soon.
